    The invention relates to a form-locking connection between a first housing part (11, 21, 31, 41, 51) which has a first flange (11a, 21a, 31a), and a second housing part (12, 22, 32, 42, 52), which has a second flange (12a, 22a, 32a), with form-locking elements designed as projections and recesses, wherein an insert part (13, 23, 33, 43, 53) can be clamped between the flanges (11a, 12a; 21a, 22a; 31a , 32a) and wherein the recesses (1 lb, 12b, 21b, 22b; 31b, 31c, 32b, 32c, 41b, 42b, 51a) are arranged both in the first and also in the second flange (11a, 21a, 31a, 12a , 22a, 32a) and the projections (13a, 13b, 23a, 23b, 33a to 33d, 43a, 43b, 53a) are arranged on both sides of the inlay part (13, 23, 33, 43, 53).

    专利说明:

    According to a further preferred embodiment, the projections can be designed as closed embossments, for example as studs or cantilevers, which are also arranged on both sides of the insert part and engage pre-locking in correspondingly shaped embossments in the soles.
    According to a further preferred embodiment, the projections can be solidly shaped, for example as cylindrical elevations, which project from both sides of the insert part and engage in the recesses.
    According to a further preferred embodiment, the inlay part can be designed as a plastic part. The manufacture is preferably carried out by injection molding, the protrusions being sprayed on the inlay part.
    According to a further preferred embodiment, the projections can be welded at the insert part. This allows tool costs to be saved.
    According to a further preferred embodiment, a sealing means is arranged between the inlay part and at least one end. This achieves a sealed connection between the two parts of the house in the area of the island plan.
    According to a further preferred embodiment, the sealing means is designed as an elastomeric layer, which is vulcanized on the inlay part, in particular in the area of the projections or embossments. Thereby, the insert part and the seal can be mounted as a part.
    Exemplary embodiments of the invention are shown in the drawings and are described in more detail below, whereby further features and / or advantages may appear from the description and / or the drawings. Fig. 1 shows a known gear housing with several housing planes, Fig. 2 a first embodiment of the invention with an insert part between two housings, Fig. 3 a second embodiment of the invention for an installation part, Fig. 4 a third embodiment of the invention for an insert part, Fig. 5 a fourth embodiment of the invention for an insert part, Fig. 6 a fifth embodiment of the invention for an insert part and Fig. 7 a section through the insert part according to Fig. 6 with seal.
    Fig. 1 shows a gear housing 1, which via a 3 end 3 is connected to a flywheel housing 2. The gear housing 1 is divided into individual housing parts or sections 7, 8, 9, 9a by further fl ends 4, 5, 6. Through the end connections, the housing parts are sealed on the one hand, and on the other hand, transverse forces and / or torque are transmitted from one to the other housing part via the end connections. In this context, with regard to more detailed details, reference is made to the above-mentioned earlier application from the applicant with the official file designation DE 10 2011 003 324.6, the entire scope of which is included in the content of the present application.
    Fig. 2 shows a first embodiment of the invention for an end connection 10, which has a first housing part 11 with a first end 11a as well as a second housing part 12 with a second end 12a. The flanges 11a, 12a are evenly designed and have depressions or recesses 11b, 12b, which are distributed over the circumference of the members 11a, 12a.
    The recesses 11b, 12b are in this exemplary embodiment designed as blind hole bores, i.e. circular-cylindrical. Between the elements 11a, 12a a separate insert part 13 is clamped, as on both sides, i.e. on the side towards the first l end 11a and on the side towards the second ns end 12a have projections 13a, 13b designed as collars or penetrations. The insert part 13 is here designed as a sheet metal part, i.e. made of a metallic material; the collars 13a, 13b are manufactured by punching and pulling through and are thus formed in one piece with the insert part 13. The collars 13a, 13b engage form-locking and without play in the recesses 11b, 12b and thus provide a form-locking connection between the first housing part 11 and the second housing part 12, so that transverse forces and / or torque can be transmitted. The insert part 13 thus acts as a pre-locking transfer element between the housing parts 11, 12.
    Fig. 3 shows a second embodiment of the invention for an end connection 20 between a first housing part 21 with a first end 21a and a recess 21b and a second housing part 22 with a second end 22a and a recess 22b. Between the two ends 21a, 22a a separate insert part 23 is clamped, which on both sides has projections formed as embossments 23a, 23b, which engage form-locking in the recesses 21b, 22b. In contrast to the open penetrations 13a, 13b in the first embodiment, the embossments 23a, 23b are closed, ie. the insert part 23 has a closed surface including its projections. The insert part 23 transmits transverse forces and / or torque from the first housing part 21 to the second housing part 22 via the embossments 23a, 23b and thus acts - as in the first embodiment - as a transfer element.
    Fig. 4 shows a third embodiment of the invention for an end connection 30, which has a first housing part 31 with a first end 31a as well as a second housing part 32 with a second end 32a. In the first flange 31a, cylindrically shaped recesses 3 lb, 3 lc in the form of blind hole bores are worked in and in the second flange 32b, corresponding recesses 32b, 32c are worked in, which are arranged coaxially with the bores 3 lb, 3lc in 10 The first 31 end 31a. Between the two ends 31a, 3lb a separate insert part 33 is clamped, which on both sides has mutually opposite opposite arranged projections 33a, 33b as well as 33c, 33d. The inlay part 33 consists of a metallic material and the projections 33a to 33d are made by mass forming, so that on both sides of the inlay part material thickenings are shown in the form of cylinder stubs.
    The solidly formed projections 33a to 33d engage pre-locking and without play in the recesses 3lb, 31c on one side and in the recesses 32b, 32c on the other side. As for the previous embodiments, the inlay part 33 acts as a transfer element between the two housing parts 31, 32.
    Fig. 5 shows a variation of the exemplary embodiment according to Fig. 4, i.e. a fourth embodiment of the invention for an end connection 40 with a first housing part 41 and a second housing part 42, in which recesses 41b, 42b are incorporated. An insert part 43 has alternately on one side projections or elevations 43a and on the other side projections or elevations 43b, which pre-locking and without play engage the recesses 41b of the first housing part 41 as well as the recesses 42b of the second housing part.
    The insert part 43 is manufactured - like the insert part 32 according to Fig. 4 - by mass forming, so that solid cylinder stubs 43a, 43b arise.
    Fig. 6 shows a fifth embodiment of the invention for an end connection 50 between a first housing part 51 and a second housing part 52, between which a separate insert part 53 is clamped. The first housing part 51 has a recess designed as bore 5a, to which a threaded bore 51b, designed as threaded blind hole, connects. The insert part 53 has a projection 53a designed as a collar or pull-through, which pre-lockingly engages in the bore 5a. The second housing part 52 has a through-bore 52a arranged coaxially with the threaded bore 5b and the through-hole 53a, through which a screw bolt 54 passes. By means of the screw bolt 54, of which fls may be arranged on the circumference of the two housing parts, the two housing parts are fixed in a force-locking manner. The collar or the recess 53a of the insert part 53 has a double function in this exemplary embodiment: on the one hand it acts as a form-locking element between the two housing parts 51, 52 (further projections as for the previous exemplary embodiments are omitted here), and on the other hand the recess acts 53a as a passage opening for the screw bolt 54.
    Fig. 7 shows a section in the plane VII-VII in Fig. 6. The insert part 53 has been coated on both sides with a sealant 55, whereby the sealant 55 can be vulcanized as an elastomeric layer on both sides of the insert part 53. To improve the sealing effect, the insert part 53 has studs or bead-like shaped embossments 53b, 53c on both sides. Thus, both a front locking and a tight connection are formed between the housing parts 51, 53.
