Problems solved by technology

When the transmission shaft rotates at a high speed, the speed of the rolling elements also increases, and the friction between the rolling elements and the raceway also increases. Excessive friction will reduce the life of the bearing and generate huge noise. affect machine

[0024]Example 1

[0025]A production process of a bearing copper casting sleeve includes the following steps:

[0026]S1. Rough inspection: The non-destructive testing equipment for steel rods sorts copper materials, detects surface cracks with eddy current testing, and detects internal ultrasonic defects. It automatically paints and marks the parts of steel rods that do not meet the testing requirements, and the defective parts are scrapped;

[0027]S2. Rough boring inner hole: Fix the qualified copper material on the lathe, and use the special inner hole boring tool to make holes on the qualified copper material;

[0028]S3. Rough turning outer circle: rough turning copper outer circle, using polycrystalline diamond turning tool to rough turning copper outer circle, after rough turning, the pipe wall thickness is reduced by 0.5mm, and coarse material A is obtained;

[0029]S4. Heat treatment: Put the coarse material A obtained in step S3 into a heat treatment furnace and heat it to 270°C, the he...

Abstract

The invention discloses a production process for a copper casting sleeve of a bearing. The production process comprises the following steps: S1, blank detection: carrying out sorting, surface crack eddy current flaw detection and ultrasonic internal defect detection on a copper material by steel bar nondestructive detection equipment, automatically spraying paint and marking on a steel bar part which does not meet detection requirements, and carrying out scrap treatment on a defect part; and S2, roughly boring an inner hole, namely fixing the qualified copper material on a lathe, and forming ahole in the qualified copper material by using a special inner hole boring cutter. According to the method, the blank is detected, so that the disqualification of the quality of the produced copper casting sleeve caused by the defects of the blank is avoided; and the strength of the copper cast sleeve is further improved by carrying out heat treatment on the processed semi-finished coarse material. According to the production process for the copper casting sleeve of the bearing, the copper cast sleeve is easier to process, and a processing procedure of the copper cast sleeve is simplified.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to a production process of a bearing copper casting sleeve. Background technique [0002] With the development of science and technology, some precision machinery and high-end household appliances put forward stricter requirements on the vibration and noise of deep groove ball bearings. These products not only require the bearings to be used at high speeds, but also require the bearings to have low vibration and good sound quality. Suitable for high speed and low noise occasions. [0003] In order to ensure that the bearing is suitable for high-speed and low-noise applications, it is necessary to ensure the high precision of the manufacturing process of each component of the bearing. When the bearing is working, the inner ring of the bearing moves together with the transmission shaft, and the inner ring of the bearing drives the rolling elements to run. When the transmi...
