Outer ring loading tool of tapered roller bearing

Abstract

The invention discloses an outer ring loading tool of a tapered roller bearing, which is characterized in that a bearing locating shaft is fixedly mounted in a pressure head through a bolt; three jack catches are arranged on the bottom end face of the bearing locating shaft; the jack catches are mounted on the bottom of the bearing locating shaft through horizontal round pins; a jack catch spring is arranged in the bearing locating shaft on the corresponding position along axial direction; each jack catch with a lever structure takes the corresponding horizontal round pin as a rotating pivot; each jack catch spring is resisted on the upper surface of the inner end of the corresponding jack catch; the tool can act on the lower surface of the inner end of each jack catch; a convex edge protruded along radial direction is arranged on the bottom side of the outer end of each jack catch; the bearing outer ring can be supported on the convex edge. The outer ring loading tool can be convenient for loading in the press fitting process of the bearing outer ring; ensures coaxiality; increases press fitting precision, and simplifies the structure, and the bearing outer ring is convenient to process and assemble.

Description

technical field [0001] The invention relates to a feeding tool used in the press-fitting process of the outer ring of a tapered roller bearing of an intermediate shaft of a gearbox. Background technique [0002] In the existing technology, in the press-fitting of the outer ring of the gearbox intermediate shaft bearing in the automobile assembly industry, the feeding tooling for the outer ring of the bearing is as follows: figure 1 In the structure shown, the polyurethane pad 1 is connected to the anti-rotation sleeve 7 with the screw 5 through the pressure plate 2, the outer circumference of the anti-rotation sleeve 7 is provided with a positioning ring 6, and an annular groove is opened on the outer peripheral surface of the polyurethane pad 1, through which the polyurethane The deformation of the pad 1 snaps the bearing outer ring 20 into the annular groove. In the process of pressing the pressure head 4 downward through the upper pressure head seat 8 through the upper p...

AI Technical Summary

Problems solved by technology

[0003] 1. The amount of deformation of the polyurethane pad is not easy to control. If the amount of deformation is too large, it will be laborious to manually load the material, which will increase the labor intensity of the workers. If the amount of deformation is too small, due to the size error of the workpiece, some workpieces will not hang and fall off and damage the workpiece; at the same time, Polyurethane pads wear out easily and constantly need to be replaced during use;

[0004] 2. The deformation of the polyurethane pad is uneven, resulting in inaccurate centering and low coaxiality when loading the outer ring of the bearing, resulting in low equipment accuracy;

[0005] 3. During the press-fitting process, the automatic return of the outer ring of the bearing is realized by the bottom end face of the polyurethane pad touching the workpiece, which is compressed and deformed to drive the bearing positioning shaft 3 to move upward relative to the pressure head 4 and the outer ring of the bearing, and then reset by the spring. The overall structure Complicated, not conducive to processing and assembly
