Multifunctional bearing assembly with constant pressure and positioning functions

Abstract

The invention relates to the technical field of bearing manufacturing, and discloses a multifunctional bearing assembly with constant pressure and positioning functions. The multifunctional bearing assembly comprises an outer ring; inner rings are assembled in the outer ring, and the two inner rings are assembled in the outer ring in a vertically stacked manner; first arc-shaped grooves are formedin the outer side of the bottom end of the inner ring at the upper end and the outer side of the top end of the inner ring at the lower end, and corresponding second arc-shaped grooves are formed incorresponding positions of the inner wall of the outer ring; and steel balls are assembled between the two inner rings and the outer ring. According to the multifunctional bearing assembly, by adopting the separate design for the inner rings and the integrated design for the outer ring, the effect of compensation after roller path abrasion can be achieved, and the bearing has a certain buffering effect under an impact load; and besides, the inner rings are combined together through an inner race and an elastic gasket, the product achieves pre-tightening through the elastic gasket under a smallload, and the end face of the inner race is in rigid contact with the end faces of the inner rings under a high load to achieve large-load bearing.

Description

technical field [0001] The invention relates to the technical field of bearing manufacture, in particular to a multifunctional bearing assembly with constant pressure and positioning. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main multi-function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The existing bearing is composed of an inner ring, an outer ring, steel balls and a fixing frame. During its use, The rollers will wear the inner ring, reduce the service life, and cannot effectively balance the preload of parts under small loads and the carrying capacity under high loads. Based on this, we propose a multifunctional bearing with constant pressure and positioning components. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: during the use o...
