    COMPACT MOTOREDUCER TECHNICAL FIELD OF THE INVENTION
    The invention relates to the field of geared motors comprising a brushless type electric motor, associated with a speed reduction gear train. More particularly, it refers to a very compact solution using the clever combination of a brushless electric motor with a compact gear train.
    By way of non-limiting examples, the invention is intended to be used to actuate automobile thermoregulation valve flaps, or to actuate fluid circulation control assemblies (air, water, fuel, etc.). ).
    STATE OF THE PRIOR ART
    In the state of the art, it is already well known to use geared motor assemblies associating an electric motor to a compact gear system having at least two pinion / gearwheel assemblies per carrier axis.
    EP0371690 discloses for example a transmission mechanism where the mechanical reduction assembly is placed at the end of the output shaft of the electric motor.
    It is also known to provide mechanical reduction systems with compact gears as for example described in DE4342185.
    It is also known, more recently, to combine brushless electric motors with such compact reduction systems as described for example in US8403376.
    It is also known to associate brushless motors compact reduction systems with spur gears as described in patent EP1194999.
    These devices of the prior art are intended to solve the general problem of having a relatively compact mechanical reduction assembly.
    However, these devices do not make it possible to obtain a very good compactness of the geared motor assembly, or a sufficient compactness, in specific applications. Particularly, in the case of the actuation of thermoregulation flap in a motor vehicle, the market requires ever larger and smaller geared motor assemblies implying a reduced footprint compared to the state of the art.
    Thus, the solutions of the state of the art using compact reducers having at least two sets of pinions / toothed gear carrier axis do not fulfill the demands imposed in this type of applications where a better integration between the motor and the reducer must be realized, in particular by integrating these elements in a single relatively flat and narrow box compared to existing solutions.
    The integrated solutions do not have the use of reduction sets sufficiently compact.
    SUMMARY OF THE INVENTION
    The present invention aims to overcome the disadvantages of the state of the art by proposing a geared cleverly combining a brushless electric motor and a set of gear reduction gears.
    To do this, the present invention proposes to strengthen the symbiosis between the brushless electric motor and the reduction assembly by placing the first axis carrying a first pinion / gearwheel assembly between two electrical coils carried by the motor stator. electric. The toothed wheel is thus disposed closer to the axis of the motor and the formed geared motor unit is thus very compact and much more compact than the solutions of the prior art.
    More particularly, the invention proposes a geared motor consisting of a housing comprising a brushless motor having at least two electrical phases, a rotor rotating about an axis, and composed of a stator assembly having at least two poles each carrying coils whose winding axes are spaced at a mechanical angle of less than 180 ° and extend radially, and a gear train, the gear train comprising: a first axis placed in the angular space formed between the two poles, said first axis carrying a first assembly formed by a pinion (Pe1, Pe1h) and a toothed wheel (Re1, Re1h) coupled, the toothed wheel (Re1, Re1h) being placed above the pinion (Pe1 , Pe1h) and having a radius greater than the pinion (Pe1, Pe1h), the toothed wheel (Re1, Re1h) meshing with an input gear rotating about the axis of the rotor, the toothed wheel (Re1, Re1h) being disposed at above said poles carrying the coils, all the axes of the gear train being parallel to each other and parallel to the axis of the rotor, characterized in that the gear train has at least one axis carrying two sets gear / pinion rotating about said axis.
    As a result, the geared motor is particularly compact with typical reduction ratios greater than 1: 200.
    In one embodiment, the electric motor is two-phase and comprises two coils whose winding axes are spaced at an angle of 90 °.
    In another embodiment the electric motor is three-phase and comprises three coils whose winding axes are spaced at an angle of about 120 °.
    In another embodiment the electric motor is three-phase and comprises three coils whose winding axes are spaced at an angle of 60 °.
    Advantageously, the first axis carries two sets gear / gear, the gear wheels of each set being disposed above the coils.
    According to a particular embodiment, the gear train has at least four reduction stages, with a second axis supporting a second and a third pinion / gearwheel assembly, respectively upper and lower, free in relative rotation, said second set upper being formed by a wheel Re2h and a pinion Pe2h, said third lower assembly being formed by a wheel Re2b and a pinion Pe2b, the gear train comprises a third axis supporting a fourth assembly formed by a wheel Re3H and a pinion Pe3h and said wheel Re2h meshing with the pinion Pe1 of said first set, said pinion Pe2h meshing with said wheel Re3h of said fourth set, said pinion Pe3h meshing with the wheel Re2b of said third set.
    According to another particular embodiment the gear train has at least four stages of reduction, the first axis comprises a second pinion / gearwheel assembly formed by a Re1b wheel and a pinion Pe1b, the gear train comprises a second gear supporting axle: a third assembly formed by a wheel Re2h and a pinion Pe2h and a fourth assembly formed by a wheel Re2b and a pinion Pe2b, and said wheel Re2h meshing with the pinion Pe1h of said first set, said pinion Pe2h meshing with said wheel Re1b said second set, said pinion Pe1b meshing with the wheel Re2b of said fourth set.
    In an alternative embodiment said pinion Pe2b drives the output axis.
    In one embodiment, said third axis further comprises a wheel Re3b driven by said pinion Pe2b, said wheel Re3b driving a ring gear RDS output surrounding the output axis.
    In another embodiment, said pinion Pe2b drives a ring gear RDS output surrounding the output axis.
    Alternatively said RDS output ring gear has a through opening.
    Advantageously, each of said sprocket / sprocket assemblies comprises a wheel placed above the sprocket.
    To reduce the overall impression of the geared motor, the first axis is advantageously placed in contact with the stator assembly on its outer periphery.

    DETAILED DESCRIPTION OF AN EMBODIMENT
    [0029] Figure 1 schematically shows a first typical embodiment of the invention. The geared motor is composed of a housing (16) in which is found at the input of the gear motor a brushless type electric motor consisting of a stator assembly (1) wound which magnetically cooperates with a rotor (9) consisting of one or several pairs of magnetic poles. This rotor (9) is guided in rotation by an input shaft (2) and is extended by an input gear (3) which meshes with a gear train forming a mechanical reduction gear, reducing the mechanical stroke and multiplying the effort at the exit of this train.
    This gear train is composed of five or six stages of reduction (depending on the Re3b / RDS link discussed below) symbolized by pinion / gearwheel assemblies carried by a first (4), a second (5), a third (6) fixed axis as well as an output axis (7). All the axes (4,5,6,7) of this gear train are parallel to each other and parallel to the input axis (2).
    The first axis (4) carries a gear Re1 coupled to a pinion Pe1, these two elements rotating about the first axis (4). The toothed wheel Re1 meshes with the toothed input gear (3), producing a first reduction stage. Advantageously, the first axis (4) passes through the volume in which fits the stator assembly (1) wound and the gear Re1 is disposed above the stator assembly (1) wound.
    The second axis (5) carries a gear Re2h coupled to a pinion Pe2h, these two elements rotating about the second axis (5), and a gear Re2b coupled to a pinion Pe2b, these two elements also rotating. around the second axis (5). The pinion Pe1 meshes with the toothed wheel Re2h, realizing a second reduction stage.
    The third axis (6) carries a gear Re3h coupled to a pinion Pe3h, these two elements rotating about the third axis (6), and a gear Re3b also rotating about the third axis (6). The toothed wheel Re3h meshes with the toothed gear Pe2h, realizing a third reduction stage, the toothed wheel Re2b meshes with the toothed gear Pe3h, realizing a fourth reduction stage, and the gear wheel Re3b meshes with the toothed gear Pe2b, producing a fifth stage. reduction.
    The output shaft (7) carries a toothed output wheel RDS rotating about the output axis (7). A connecting member (8) makes it possible to couple the toothed output wheel RDS to any external member to be moved (not shown). The Re3b gear meshes with the RDS gear output wheel. It should be noted that this latter gear link can be both in a unit reduction ratio and a non unit ratio. This connection advantageously makes it possible to benefit from a hollow RDS toothed exit wheel that can more easily be connected to an external member. The RDS toothed output wheel can protrude from or out of the housing (16), but it can also be inside the housing (16). In the latter case, the outer member to be coupled enters the interior of the housing (16).
    Figures 2a and 2b show a first embodiment of a geared motor according to the first example. It comprises the use of a three-phase electric motor, having a stator assembly (1) composed of an assembly of sheets of soft ferromagnetic materials, for example of silicon-iron, and of three electric coils (10), (11) and (12) which are carried by poles, for example (14), of the stator assembly (1) and whose winding axes are spaced approximately 60 ° from each other. In this way, the total size of the geared motor, which can be included in a housing (16) whose imprint can be appreciated in FIG. 2a, is minimized because the gear reduction gear and the coiled poles are on the same side between the axis (2) of the rotor (9) and the RDS output wheel. The housing (16) receiving this geared motor assembly can be reduced in size compared to the prior art.
    This stator assembly (1) also has several non-wound poles, for example (13), used to close the magnetic flux of the formed circuit, and to manage the detent couple, as taught by the state of the art in the matter.
    This motor also comprises a rotor (9) having a magnetized ring, rotating around the input axis (2).
    The first axis (4) around which rotates the toothed gear assembly Re1 and pinion Pe1, is placed between the coils (11) and (12), in contact with the stator assembly (1) on the periphery of the stator assembly. The contact is not absolutely necessary for the invention but the desired compactness will be all the better as the first axis (4) is close to the input axis (2). Within the meaning of the invention, it is considered that the first axis (4) is between the coils (11) and (12) when these coils (11, 12) are separated by a mechanical angle less than or equal to 180 °, here about 60 ° and that the distance D24 from the input axis (2) to the first axis (4) is less than the distance D2b from the input axis (2) to the radial end of the coils (11). , 12).
    Then we find all the elements described in Figure 1 to the RDS output wheel which has a connecting member (8) having a shape for coupling to an external member not shown. It should be noted that, in this example, the RDS wheel is not linked and guided by an output axis (7), contrary to what is shown in Figure 1, but is guided by the form (15) given to the RDS wheel on one side.
    The connecting member is preferably hollow and traversing so that the coupling with the outer member to move can be mounted indifferently on one side or the other of the geared motor. This reversible assembly is particularly possible thanks to the use of the gear Re3b which meshes with the output gear RDS in a reduction ratio unit or close to the unit, to separate the RDS wheel from other gears and allowing a easier connection of the external member to connect.
    The compactness of the solution is therefore ensured in the first place by the reduced spacing between the axis (2) of the rotor (9) and the connecting member (8) at the output thanks to the judicious placement of the first axis ( 4) between the coils inside the volume in which the stator assembly fits. Secondly, the compactness is ensured by the use of a gear reduction unit which has at least one axis carrying two pinion / gearwheel assemblies. The reduction ratio that can be achieved is therefore very important, typically more than 1: 450, in a small footprint.
    Figures 3a and 3b show a second embodiment of a geared motor according to the first example. It comprises the use of a three-phase electric motor, having a stator assembly (1) composed of an assembly of sheets of soft ferromagnetic materials, for example of silicon-iron, and of three electric coils (10), (11) and (12) which are carried by poles, for example (14), of the stator assembly (1) and which are distributed angularly every 120 °. This stator assembly (1) also has several non-coiled poles, for example (13), serving to close the magnetic flux of the circuit formed, and to manage the detent couple, as taught by the state of the art in the material. This motor also comprises a rotor (9) having a magnetized ring, rotating around the input axis (2).
    The first axis (4) around which rotates the toothed gear assembly Re1 and pinion Pe1, is placed between the coils (11) and (12), but without contact with the stator assembly (1). The contact is not absolutely necessary for the invention but the desired compactness will be all the better as the first axis (4) is close to the input axis (2). Within the meaning of the invention, it is considered that the first axis (4) is between the coils (11) and (12) when these coils (11, 12) are separated by a mechanical angle less than or equal to 180 °, here about 120 ° and that the distance D24 from the input axis (2) to the first axis (4) is less than the distance D2b from the input axis (2) to the radial end of the coils (11). , 12).
    Then we find all the elements described in Figure 1 to the RDS output wheel which has a connecting member (8) having a shape for coupling to an external member not shown. It should be noted that, in this example as in that of Figures 2a and 2b, the RDS wheel is not linked and guided by an output axis (7), contrary to what is shown in Figure 1, but is guided by the shape (15) given to the RDS wheel on one side.
    The connecting member is preferably hollow and traversing so that the coupling with the outer member to be moved can be mounted indifferently on one side or the other of the geared motor. This reversible assembly is particularly possible thanks to the use of the gear Re3b which meshes with the output gear RDS in a reduction ratio unit or close to the unit, to separate the RDS wheel from other gears and allowing a easier connection of the external member to connect.
    The compactness of the solution is therefore ensured in the first place by the reduced spacing between the axis (2) of the rotor (9) and the connecting member (8) output through the judicious placement of the first axis ( 4) between the coils inside the volume in which the stator assembly (1) fits. Secondly, the compactness is ensured by the use of a gear reduction unit which has at least one axis carrying two pinion / gearwheel assemblies. The reduction ratio that can be achieved is therefore very important, typically more than 1: 450, in a small footprint.
    [0046] Figure 4 schematically shows a second typical embodiment of the invention. At the input of the gearmotor there is an electric motor of the brushless type consisting of a stator assembly (1) wound which magnetically cooperates with a rotor (9) composed of one or more pairs of magnetized poles. This rotor (9) is carried by an input shaft (2) and is extended by an input gear (3) which meshes with a gear train forming a mechanical reduction gear, reducing the mechanical travel and multiplying 'effort out of this train.
    Unlike the first example, the reduction gear gear train is more compact with a gears axis less gear. This gear train is composed of four or five reduction stages (depending on the nature of the Pe2b / RDS link discussed below) symbolized by pinion / gearwheel assemblies carried by a first (4) and a second ( 5) fixed axes as well as an output axis (7). All the axes (4,5,7) of this gear train are parallel to each other and parallel to the input axis (2).
    The first axis (4) carries a toothed gear Re1h coupled to a pinion Pe1 h, these two elements rotating about the first axis (4). The toothed wheel Re1 h meshes with the toothed input gear (3), producing a first reduction stage. Advantageously, the first axis (4) is passing through the volume in which fits the stator assembly (1) wound and the toothed wheel Re1h is disposed above the stator assembly (1) wound. This first axis (4) also has a gear Re1b coupled to a pinion Pe1b, these two elements rotating about the first axis (4).
    The second axis (5) carries a gear Re2h coupled to a pinion Pe2h, these two elements rotating about the second axis (5), and a gear Re2b coupled to a pinion Pe2b, these two elements also rotating. around the second axis (5). The toothed wheel Re2h meshes with the pinion Pe1h, realizing a second reduction stage. The toothed wheel Re1b meshes with the toothed gear Pe2h, realizing a third reduction stage, the toothed wheel Re2b meshes with the toothed gear Pe1b, realizing a fourth reduction stage.
    The output shaft (7) carries a toothed output wheel RDS rotating about the output axis (7) fixed. A connecting member (8) makes it possible to couple the toothed output wheel RDS to any external member to be moved (not shown). The Re2b gear meshes with the RDS gear output wheel. It should be noted that this latter gear link can be both in a unit reduction ratio and a non unit ratio. In the case of a unitary ratio, this connection advantageously makes it possible to benefit from a hollow RDS toothed exit wheel that can more easily be connected to an external member.
    To concretely illustrate an embodiment according to this second example, FIGS. 5a and 5b show the realization of a geared motor taken from the example of using a two-phase brushless motor having two coils (11) and ( 12), phase shifted mechanically and electrically by 90 °.
    The stator assembly (1) is composed of an assembly of sheets of soft ferromagnetic materials, for example iron-silicon and two electrical coils (11) and (12) which are carried by poles, for example (14), the stator assembly (1) and whose winding axes are spaced approximately 90 ° from each other. In this way, the overall size of the geared motor, which can be part of a housing (16) whose imprint can be appreciated in Figure 5a, is minimized because the gear reducer and the coiled poles are on the same side between the axis (2) of the rotor (9) and the RDS output wheel. The housing (16) receiving this geared motor assembly can be reduced in size compared to the prior art.
    This stator assembly (1) also has several non-coiled poles, for example (13), used to close the magnetic flux of the formed circuit, and to manage the relaxation torque, as taught by the state of the art in the matter. This motor also comprises a rotor (9) having a magnetized ring, rotating around the input axis (2).
    The first axis (4) around which rotates the toothed gear Re1h and Pe1h gear, is placed between the coils (11) and (12) in contact with the stator assembly (1). The contact is not absolutely necessary for the invention but the required compactness will be all the better as the first axis (4) is close to the stator assembly (1). Within the meaning of the invention, it is considered that the first axis (4) is between the coils (11) and (12) when these coils (11, 12) are separated by a mechanical angle less than or equal to 180 °, here about 90 ° and that the distance D24 from the input axis (2) to the first axis (4) is less than the distance D2b from the input axis (2) to the radial end of the coils (11). , 12).
    Then we find all the elements described in Figure 4 to the RDS output wheel which has a connecting member (8) having a shape for coupling to an external member not shown.
    The connecting member is preferably hollow and traversing so that the coupling with the outer member to be moved can be mounted indifferently on one side or the other of the geared motor.
    The compactness of the solution is therefore ensured in the first place by the reduced spacing between the axis (2) of the rotor (9) and the connecting member (8) at the output thanks to the judicious placement of the first axis ( 4) between the coils inside the volume in which the stator assembly fits. Secondly, the compactness is ensured by the use of a gear reduction unit which has at least one axis carrying two pinion / gearwheel assemblies. The reduction ratio that can be achieved in this example is therefore very important, typically more than 1: 450, in a small footprint.
