Method for filling and sealing rollers of integrated special-shaped crossed roller bearing

Abstract

The invention relates to the technical field of bearings, and discloses a method for filling and sealing rollers of an integrated special-shaped crossed roller bearing. The method comprises the following steps of: forming a roller filling hole on a bearing outer ring (1) which corresponds to a roller path of a bearing inner ring (2) and is connected with a reduction box; filling the rollers into the roller filling hole (6) and then allowing the rollers to sequentially enter a roller path which is formed by combining the bearing outer ring and the bearing inner ring; and after the rollers are distributed on the roller path which is formed by combining the bearing outer ring and the bearing inner ring, inserting a spring pin (7) into a spring pin hole (10) on the end face of the bearing outer ring to ensure that a plunger (4) is integrated with the bearing outer ring so as to finish sealing. The manufactured integrated crossed roller bearing with large contour dimension for a micro reduction box can replace a separate crossed roller bearing, the filling problems of the rollers of the integrated crossed roller bearing, and an isolated block are solved, the rated load, rigidity and intensity of the bearing are increased, and bearing capacity and rotation speed of the whole reduction box can be improved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a method for filling and sealing rollers of an integral special-shaped crossed roller bearing for a miniature reducer. Background technique [0002] The reducer is a mechanism that can transmit power and change the speed, and is widely used in mechanical equipment in various fields. With the development of science and technology, the requirements for the reducer are getting higher and higher, and at the same time, higher requirements are put forward for the bearing, which is an important part of the reducer. A miniature reducer is composed of three parts: shell, outer ring or inner ring separated cross roller bearing and reduction mechanism. Affected by the installation space, the reducer can only be installed with small bearings, which affects the load-carrying capacity of the reducer. The integral special-shaped crossed roller bearing we prepared can solve this problem very w...

AI Technical Summary

Problems solved by technology

Affected by the installation space, the reducer can only be installed with small bearings, which affects the load-carrying capacity of the reducer. The integral special-shaped crossed roller bearing we prepared can solve this problem very well.

However, the filling and sealing of the rollers of the integral integral special-shaped crossed roller bearing has not been solved, which restricts the possibility of mass production and promotion of this product
