Titanium alloy bearing backfill process

Abstract

The invention provides a titanium alloy bearing backfill process. The process comprises the following steps that pretreatment before ball loading is conducted; specifically, a titanium alloy bearing billet is subjected to the machining procedures of turning, heat treatment, grinding and milling, and an intermediate part is selected through intermediate inspection; balls are loaded, specifically, the intermediate part is taken for loading the balls, and a semi-finished bearing is obtained; welding is conducted, specifically, ball loading holes of the semi-finished bearing are subjected to backfill welding, a welding machine is adopted for spot welding of the ball loading holes, and it is guaranteed that a welding spot is higher than the outer circle surface of an inner ring and the inner circle surface of an outer ring of the semi-finished bearing; ultrasonic inspection is conducted, specifically, a bearing part with a qualified welding atlas is selected out; and grinding is conducted, specifically, the welding spot is repaired until being consistent with the outer circle surface of the inner ring and the inner circle surface of the outer ring of the bearing part. The titanium alloy bearing backfill process is mainly used for backfilling of the ball loading holes, rolling bodies of the bearing rotate in a complete closed loop, slipping is avoided, the reliability of the bearing is greatly enhanced, and the service life is obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a titanium alloy bearing backfilling process. Background technique [0002] Bearings are an important part of contemporary machinery and equipment. They are widely used and can be divided into rolling bearings, radial bearings, ball bearings, thrust bearings, etc. The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. [0003] Most of the existing bearings are made of ordinary GCR15 or stainless steel 420, 440 and other materials. Under the working conditions of strong acid or strong alkali, the service life of this kind of bearing is short, resulting in unsustainable production and decreased productivity. Most of them cannot meet the customer's production requirements. need. Bearings often need to work at higher speeds, but the bearings produced by the existing process...

Problems solved by technology

[0003] Most of the existing bearings are made of ordinary GCR15 or stainless steel 420, 440 and other materials. Under the working conditions of strong acid or strong alkali, the service life of this kind of bearing is short, resulting in unsustainable production and decreased productivity. Most of them cannot meet the customer's production requirements. need

Bearings often need to work at a higher speed, but the bearings processed by the existing processing technology, when rotating at high speed, are prone to ball jamming and ball removal at the position of the ball hole, which seriously affects the normal operation of the equipment
