Description

Technical Field

[0001] The utility model relates to the technical field of gearbox bearing disassembly, in particular to an outer tapered sleeve for disassembling a front bearing of an intermediate shaft. Background Art

[0002] A gearbox is a mechanical device used in automobiles or other means of transportation, which is used to adjust the matching relationship between the engine output speed and the wheel speed. It achieves the adjustment of different vehicle speeds and torque outputs by changing the gear ratio. When the gearbox is damaged or fails, the gears and bearings in the gearbox need to be removed so that the staff can inspect and repair the gearbox. The front bearing of the intermediate shaft of the gearbox refers to the bearing installed on the intermediate shaft for supporting and positioning the intermediate shaft. It plays the role of bearing axial and radial loads and reducing friction and wear. When removing this bearing, a suitable bearing removal tool is usually used. The suitable removal tool is usually divided into two main structures: an outer tapered sleeve and an inner tapered sleeve. The inner tapered sleeve is used to clamp the bearing, and the outer tapered sleeve plays the role of fixing the inner tapered sleeve and protecting it. In the prior art, the outer tapered sleeve in the sleeve-type removal tool is mostly a single sleeve ring. When used, the outer tapered sleeve is easily loosened, resulting in the inner tapered sleeve being unable to continue to fix the bearing, which affects the progress of the bearing removal work.
