Full-ball angular contact bearing trapping tool device with outer ring having ball locking mouths

Abstract

A full-ball angular contact bearing trapping tool device with an outer ring having ball locking mouths comprises a coat, a spring, an intermediate sliding sleeve, a baseboard and a positioning shaft with the cross section being a T-shaped shoulder, wherein a plurality of steps are on the upper part of the T-shaped shoulder; the central hole of the intermediate sliding sleeve having a U-shaped cross section is sleeved on the positioning shaft; the T-shaped shoulder of the positioning shaft slides in the U-shaped intermediate sliding sleeve; the intermediate sliding sleeve slides in the coat; the full-ball angular contact bearing inner ring and the intermediate sliding sleeve are positioned on the lower bottom of the intermediate sliding sleeve and the spring contact positioning shaft; and the baseboard is at the lower part of the coat and is fixed to the coat. The assembling efficiency of the device is high, and the assembled bearing quality is high.

Description

technical field [0001] The tooling device of the bearing assembly of the present invention can be used for the assembly of full-spherical angular contact ball bearings with inseparable inner and outer rings of the miniature and small series of outer rings and inner holes with locking ball ports. Background technique [0002] Angular contact ball bearings have a high limit speed, can bear radial load and axial load at the same time, and can also bear pure axial load. The axial load capacity is determined by the contact angle and increases with the increase of the contact angle. Angular contact ball bearings are divided into two types: inner and outer rings, which are separable and non-separable. Each angular contact ball bearing can be subdivided into outer ring with lock ball and inner ring with lock ball. [0003] Angular contact ball bearings are widely used. Generally speaking, most of them are used in high-speed rotating occasions with light loads. Relatively, the price ...

AI Technical Summary

Problems solved by technology

[0006] This kind of fitting method is not suitable for full-ball angular contact, because there is no cage in full-ball bearings, so the steel balls cannot be fixed; in addition, the method of heating the outer ring at high temperature is not suitable for mass production, and at the same time, it is harmful to workers. Certain security risks, low efficiency

And because it is necessary to hold the components by hand to assist in the fitting, it is generally not suitable for the fitting of miniature angular contact bearings.
