Abstract
Description
Technical Field
[0001] This utility model relates to the field of transmission bearing technology, specifically a transmission bearing for a clutch. Background Technology
[0002] The clutch bearing is a crucial component of an automotive clutch system, primarily located inside the clutch housing or flywheel housing. The transmission bearing consists of an eccentric mechanism, an internal gear ring, and a transmission ring positioned between them, and is made of medium-carbon quenched and tempered steel. Its main function is to support rotating mechanical parts, reduce the coefficient of friction during operation, and ensure rotational accuracy.
[0003] Existing transmission bearings for clutches still have certain shortcomings in actual use: the mounting surfaces of the outer ring of existing transmission bearings and clutch housings mostly use symmetrical positioning holes (such as evenly distributed circular holes) or universal error-proof markings (such as arrow markings). During installation, it is necessary to manually align the hole positions or identify the direction markings before tightening with bolts. However, such symmetrical positioning holes allow the outer ring of the bearing to be installed at any angle. If the operator is negligent or the markings are unclear, it is easy to cause the bearing to be installed in reverse / misaligned, leading to problems such as uneven wear of the raceway and abnormal vibration.
[0004] Based on the shortcomings of existing technology, this utility model designs a transmission bearing for a clutch. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a transmission bearing for clutches, which has the advantages of preventing reverse or misaligned installation of the bearing and avoiding uneven wear of the raceway and abnormal vibration.

The access structure includes an access pipe, one end of which is fixedly fitted with a skirt cover, and an inner groove is formed inside the access pipe. The bearing structure includes a bearing outer ring, with side blocks fixedly installed on both sides of the outer surface of the bearing outer ring. The outer surfaces of the two side blocks are provided with guide arrows pointing in the same direction. The upper and lower sides of the outer surface of the bearing outer ring are fixedly fitted with protrusions, and fastening bolts are threaded into the two protrusions. The two fastening bolts can be threadedly connected to the inner groove.
[0007] As a preferred embodiment of the present invention, the outer surface of the access pipe is provided with a first threaded groove, and a threaded ring is threadedly installed on the outer surface of the first threaded groove.
[0008] As a preferred technical solution of this utility model, the inner groove has meshing grooves on both sides, and the arc surfaces of the two meshing grooves match the arc surfaces of the side blocks.
[0009] As a preferred technical solution of this utility model, the outer surfaces of the two side blocks are provided with second threaded grooves, and the two second threaded grooves can be connected with the first threaded groove.
[0010] As a preferred embodiment of this utility model, the inner ring of the bearing is mounted inside the outer ring of the bearing by means of rotating steel balls.
[0011] As a preferred embodiment of this utility model, the inner ring of the bearing is coaxial with the inlet pipe.
[0012] As a preferred embodiment of this utility model, the inner wall of the bearing inner ring is provided with a perforated groove, which is used to connect the drive shaft.
