Planet speed reducer planet assembly bearing assembling tool

Abstract

The invention discloses a planet speed reducer planet assembly bearing assembling tool. The planet speed reducer planet assembly bearing assembling tool comprises a connecting beam and cushion blocksdetachably installed at the two side ends of the lower end face of the connecting beam. The cushion blocks are arc cushion blocks. Each cushion block comprises two protruding edges arranged on one endface, wherein one of the protruding edges has the radial width and the curvature radius the same to those of the inner ring of a to-be-assembled bearing, the other one of the protruding edges has theradial width and the curvature radius the same to those of the outer ring of the to-be-assembled bearing, the end faces of the two protruding edges are flush, and accordingly, the cushion block can make plane contact with the inner ring and the outer ring of the to-be-assembled bearing at the same time. According to the planet speed reducer planet assembly bearing assembling tool, all-direction assembling adjusting of the bearing can be achieved; downward movement of the inner ring and the outer ring of the bearing at the same time and bearing inclination adjustment can be achieved by slightly impacting the connecting beam; and the planet speed reducer planet assembly bearing assembling tool can be applicable to assembling of multiple different kinds of bearings, accordingly, the planet assembly bearing assembly technology requirement can be met, the assembling precision is high, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of reducer equipment, in particular to a bearing assembly tool for a planetary component of a planetary reducer. Background technique [0002] Generally, there are two ways to assemble the bearings of the planetary assembly of the planetary reducer, one is assembled by knocking copper rods, and the other is assembled by using the mounting plate provided by a professional manufacturer. When the bearing is assembled by knocking with a copper rod, since the outer ring of the bearing is generally a small clearance fit, while the inner ring and the shaft are an interference fit, it is difficult to install the inner ring by knocking the outer ring of the bearing with a copper rod, and at the same time It will also cause damage to the bearing. In severe cases, the bearing cage will be damaged due to the low accuracy of the knocking or even the inner ring of the bearing will be hammered. When using the mounting pla...

AI Technical Summary

Problems solved by technology

When the bearing is assembled by knocking with a copper rod, since the outer ring of the bearing is generally a small clearance fit, while the inner ring and the shaft are an interference fit, it is difficult to install the inner ring by knocking the outer ring of the bearing with a copper rod, and at the same time It will also cause damage to the bearing. In severe cases, the bearing cage will be damaged or even hammered to the inner ring of the bearing due to the low accuracy of the knocking. Therefore, it is difficult to fully meet the process requirements of the bearing assembly when the copper rod is knocked on the assembled bearing.

When using the mounting plate provided by a professional manufacturer to assemble the bearing, because the upper part of the mounting plate is closed, it is affected by the height structure of the product, which cannot satisfy the installation and use of the product; It is thinner, easy to rebound when hammered by hand, and the efficiency is low; and the mounting plate is specific and can only be used for the assembly of the corresponding bearing. For the assembly of multiple different types of bearings, multiple corresponding mounting plates are required, and the cost higher
