Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted.

The use of "first," "second," and similar terms in the detailed description is not intended to imply any order, quantity, or importance, but rather is used to distinguish one element from another. It should be noted that features of the embodiments of the utility model and of the different embodiments may be combined with each other without conflict.

Fig. 1 illustrates a three-dimensional structure of a dummy separation bearing in an embodiment, fig. 2 illustrates a sectional structure of the dummy separation bearing, fig. 3 illustrates a three-dimensional structure of an annular body in the dummy separation bearing, fig. 4 illustrates a sectional structure of the annular body, and fig. 5 illustrates a three-dimensional structure of an annular contact piece in the dummy separation bearing. As shown in fig. 1 to 5, the simulated release bearing in this embodiment includes: the annular body 1, the inner edge of the contact end surface 11 of the annular body 1 protrudes axially to form an annular boss 12; the annular contact piece 2 is detachably sleeved on the annular boss 12 and tightly attached to the outer edge 110 of the contact end face 11, the outer wall of the annular body 1 and the outer wall of the annular contact piece 2 form a smooth outer wall of the analog separation bearing, and the end face of the annular boss 12 and the end face of the annular contact piece 2 form a smooth end face of the analog separation bearing.

The inner wall of the annular body 1 is formed with stepped holes 10 which are distributed in a stepped manner along the axial direction. The stepped hole 10 is used for mounting the analogue release bearing to a test fixture. After the annular body 1 and the annular contact piece 2 are assembled, a complete simulation release bearing with an integrated effect can be formed, and the simulation release bearing has a smooth outer wall and an end face, so that the simulation release bearing has the same test performance as a traditional integral simulation release bearing.

The analogue release bearing is tested in use, and wear occurs mainly at the outer edge of the contact surface with the diaphragm spring, i.e. at the annular contact plate 2. The utility model sets the analog separation bearing as a detachable annular body 1 and an annular contact piece 2, and the annular contact piece 2 is mainly contacted with the diaphragm spring in the test use process. Therefore, when the simulation release bearing is abraded, only the abraded annular contact piece 2 needs to be replaced independently, the annular body 1 of the simulation release bearing can be reused, the testing cost is reduced, practical application is facilitated, and raw materials are saved.

In one embodiment, the inner wall of the annular contact plate 2 is in interference fit with the outer wall of the annular boss 12. That is, the inner diameter R1 of the annular contact piece 2 is slightly larger than the outer diameter R2 of the annular boss 12, so that the annular contact piece 2 can be stably sleeved outside the annular boss 12 and tightly attached to the outer edge 110 of the contact end face 11 of the annular body 1 by means of interference press fitting. The outer edge of the end face of the annular boss 12 may be further provided with a chamfer 121 for guiding press fitting of the annular contact piece 2, so as to facilitate assembly between the annular contact piece 2 and the annular body 1.

In other embodiments, the annular contact piece 2 and the annular body 1 may be detachably connected, and are not limited to the above list.

Further, the outer wall of the ring-shaped body 1 is also provided with a plurality of screw holes 13, and the screw holes 13 are used for assembling studs forming a propeller type handle for operating the analog release bearing. Specifically, fig. 6 shows the structure of the propeller type handle simulating a release bearing in an embodiment, and as shown in fig. 3 and 6, a stud 40 may be screwed into each screw hole 13, and the stud 40 has a portion screwed into the screw hole 13 and a portion protruding out of the screw hole 13. The plurality of studs 40 may form a propeller handle 4 for operating the analogue throw-off bearing B. Therefore, when the simulation release bearing is installed on the test tool, the operation of the simulation release bearing B can be realized by operating the propeller type handle 4, and the operation is very convenient and labor-saving. For example, the propeller handle 4 may be turned to effect turning the analogue release bearing B into or out of position.

The screw holes 13 may be provided in plural as necessary. In this embodiment, the screw holes 13 include four circumferentially evenly distributed holes, but not limited thereto. The threaded hole 13 is a blind hole, and the depth of the hole can be set as required, so that the stud 40 can be assembled conveniently without affecting the stepped hole 10 of the annular body 1.

In addition, the screw holes 13 are disposed close to the second end face 14 of the annular body 1 opposite to the contact end face 11 thereof, so that the assembling stability between the annular body 1 and the annular contact piece 2 can be prevented from being affected.

In summary, the simulation separation bearing of the utility model is provided with the detachable annular body and the detachable annular contact piece, so that the worn annular contact piece only needs to be replaced independently when the simulation separation bearing is worn, the annular body of the simulation separation bearing can be reused, the test cost is reduced, the practical application is facilitated, and raw materials are saved.

The foregoing is a more detailed description of the utility model in connection with specific preferred embodiments and it is not intended that the utility model be limited to these specific details. For those skilled in the art to which the utility model pertains, several simple deductions or substitutions can be made without departing from the spirit of the utility model, and all shall be considered as belonging to the protection scope of the utility model.
