Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a pressure plate bearing installation structure for an automobile gearbox. Background Art

[0002] Due to the existence of bidirectional torque and helical gears in automobile gearboxes, there are bidirectional axial forces in the single shaft system. In order to prevent the movement of the shaft, the method of positioning the double-sided end faces of the outer ring of a single bearing is often used. Due to the limitations of the gearbox assembly process, one side of the pressure plate is usually flexibly integrated with the bearing for end face positioning. The pressure plate must not fall off the bearing axially and must be flexible in circumferential rotation. The common way to integrate the pressure plate into the bearing is to use riveting, but this method is unreliable for mass production, and often causes problems such as the inability to rotate flexibly in the circumferential direction and the pressure plate easily falling off the bearing when there is vibration during transportation. Therefore, a pressure plate bearing mounting structure for an automobile gearbox is invented. Utility Model Content

[0008] Rubber, the rubber is arranged on the inner diameter of the pressure plate;

[0009] A first stepped groove, wherein one side of the outer ring of the bearing is provided with a first stepped groove, and an inner cavity of the first stepped groove is provided with a pressure plate;

[0010] A second stepped groove is provided on one side of the outer ring of the bearing, and rubber is provided in the inner cavity of the second stepped groove.

[0011] As a preferred solution of the pressure plate bearing installation structure for an automobile gearbox described in the utility model, wherein: the cross section of the rubber is set to be T-shaped.

[0012] As a preferred solution of the pressure plate bearing installation structure for an automobile gearbox described in the utility model, the inner diameter of the pressure plate is smaller than the outer diameter of the first stepped groove.

[0013] As a preferred solution of the pressure plate bearing installation structure for an automobile gearbox described in the utility model, wherein: the inner diameter of the rubber is larger than the outer diameter of the second stepped groove.

[0014] As a preferred solution of the pressure plate bearing installation structure for an automobile gearbox described in the utility model, a shaft shoulder is provided on the right side of the second stepped groove.

[0015] Compared with existing technologies:

[0016] The rubber and the pressure plate are fixed together through a vulcanization process to form a pressure plate assembly, and the rubber is accommodated in the step groove by setting a step groove, which can prevent the rubber from falling off axially. In addition, the clearance between the rubber and the step groove can enable the pressure plate and the rubber assembly to achieve circumferential rotation. BRIEF DESCRIPTION OF THE DRAWINGS
