    专利说明:

    The invention relates to hydraulic engineering, in particular to axial-piston hydraulic machines with a fixed cylinder block and a rotating swing assembly.
    The aim of the invention is to relieve the trunnion by redistributing at least part of the axial forces between the trunnion of the cylinder block and the housing.
    FIG. 1 shows a machine with a vertical section1; figure 2 - the same option.
    The machine contains a fixed cylinder block 2 with pistons 3 rigidly connected to housing 1. The piston rods 4 are pivotally connected to the inclined washer 5. The inclined washer 5 rests on the bearing 6 of the swivel unit 7 placed in the cover 8 on the bearing 9 equipped with an adjusting gasket ten.
    The gasket 10 is intended for preloading, its thickness is calculated to regulate the corresponding values of the prestressing forces, shown as U and, or as a function of the ratio of the desired distribution. For example, you can accept that. In addition, the gasket 10 provides additional reliability in the event of a hydraulic compensation failure.

    with
    The geometrical axis of rotation 11 of the swiveling unit 7 coincides with the geometric axis 12 of the cylinder block 2, the central part 13 of the inclined washer 5 has a spherical bearing 14 formed by inserts mounted rotatably on the central pin 15, provided with channels 16 for lubricating the spherical bearing 14. Central axle 15 is fixed in the central part 17 of the cylinder block 2 against rotation. It is rigidly connected to the axle 18, which is installed with the possibility of interaction with the cover 8 by means of a nut 19.
    In the cylinder block 2, there is a central axial drilling 20. Between the cover 8 and the bearing 9, a hydraulic cylinder -21 can be installed, which is under pressure, which acts on the bearing 9.
    The half shaft 18 is integrally formed with the axle 15 in the form of a single piece with a through axial bore 22, in which at least one movable rod 23 is installed, equipped with a piston 24 installed in axial drilling 20 of the cylinder block 2 to form a working chamber 25 communicated with a pressure source . Between the pin 15 and the cylinder block 2 provides a gap 26 for adjusting the stroke of the piston 24.
    At the free end of the stem 23, a lock nut 27 is mounted, resting on the half shaft 18. The lock nut 27 allows blocking the stem 23 in a predetermined position in the axle 15, at which a gap 26 is formed between the axle 15 and the cylinder block 2
    The rod 23 is mounted to the semi-axis 18 with the formation of an annular chamber 28, which is connected with an axial channel 29 formed in the semi-axis 18 with lubrication channels 16 in the axle 15 for supplying lubricant to the spherical bearing 14.
    An elastic element 30 is mounted between the nut 19 mounted on the half-axle 18 and the lid 8, in particular this can be an elastic conical washer.
    The cover 8 is provided with an abutment 31 under the bearing 32 of the oscillatory transmission transmission unit 33. connected through a thrust bearing 9 with an inclined washer 5.
    The machine can be equipped with
    34 installs additional housing
    35 with cylinders 36 in which additional pistons 37 are installed to form working chambers (not shown).
    The valve may be provided with a pressure regulator 38 acting on the piston 24 and a compensation pressure occurring in the hydraulic cylinder 21.
    The inclined washer 5 cannot rotate freely due to the reaction of the connecting rod
    reverse action 39, hinged with its spherical head 40 in a bushing 41, rigidly connected through the support 42 to the housing 1 and the cylinder block
    5 2 with brackets 43.
    Bearing 42 forms the base of the bearing 44 for the drive shaft 45, equipped with a gear 46, interacting with a gear rim 47, performed on the swing node 7.
    The pressure developed in chamber 25 may be a sufficiently high pressure to balance at least some of the opposing
    5 forces applied to the trunnion 15 through the swinging unit 7 during the operation of the machine.
    The pressure in the chamber 25 acting on the piston 24 is transmitted by different parts of the rod 23 to the trunnion 15 and to the stop lock 27, which is tucked to the axle 18, and the nut 19 can transfer part of the force to the cover 8, the supporting bearing 9, while the data no force is applied to housing 1.
    24 t piston no axle 15 and transmits to it
    5, the part of the force during pumping of the working medium, the gap 26 provided between the trunnion 15 and the cylinder block 2, controls the stroke of the piston 24, while unloading the thrust bearings 6 and 9,
    0 When choosing a certain pressure in chamber 25, it is possible to make so that all the stresses that affect the pin 1P are transmitted through the half axis 18 without transferring them to housing 1, which in this case
    5 can be made very easy. The working medium in the chamber 25 is also an element of compensation for the differential expansion that occurs between the semi-axis 18, various parts of the rod 23 and
    0 cylinder block 2.
    In the embodiment shown in Fig. 2, the trunnion 15 is directly attached to the threaded portion of the rod 23, which is connected to the piston 24.
    5 The design allows the distribution of hydraulic pressures designed to balance the axial stresses on one side of the cylinder block 2 and on the other side of the cap 8. Pressure
    50 which can be created by the hydraulic cylinder 21, is fed to the swinging unit 7 and, through the thrust bearing 6, to the inclined washer 5, which allows us to reduce the axial forces between the axle 15 and the spherical original 14 of the inclined washer 5,
