Self-aligning ball bearing introduction and picture show

Nov 16, 2023

The self-aligning ball bearing is a ball bearing with a self-adjusting alignment function. It can automatically correct axis deviation between the inner and outer rings of self-aligning ball bearings during operation, ensuring regular operation. The design and manufacturing process of this kind of bearing involves knowledge and technology in multiple fields, including material science, mechanical design, manufacturing technology, etc. The various aspects of self-aligning ball bearings will be introduced in detail below.

1. Background introduction

Ball bearing is a component widely used in the field of mechanical transmission. It has the advantages of high precision, high speed, and long life. However, in practical applications, due to machining errors, improper installation, etc., the axis between the inner and outer rings of the self-aligning ball bearing is prone to deviation, which will lead to noise, heat, and other problems during the operation of the bearing, and in severe cases may even affect the bearing's performance. To solve this problem, people invented self-aligning ball bearings, which can automatically align the axis deviation between the inner and outer rings during the operation, thus ensuring regular bearing operation.

2. Working principle

The working principle of self-aligning ball bearings relies on the movement between the inner and outer rings of the self-aligning ball bearings to achieve automatic axis alignment. During operation, the angular deviation between the inner and outer rings can be adjusted automatically due to the friction between the balls inside the bearing and the inner and outer rings. When the axis deviation between the inner and outer rings is significant, the conflict between the balls and the inner and outer rings causes relative movement, which adjusts the axis deviation. The size of this friction depends on the contact area and contact pressure between the ball and the inner and outer rings.

Manufacturing process of self-aligning ball bearings

The manufacturing process of self-aligning ball bearings includes the following steps:

Material selection: The material of self-aligning ball bearings is produced with steel with high strength and good wear resistance, such as stainless steel, high carbon steel, etc.

Rough grinding: Rough grinding of the selected steel to remove defects and stress on the material's surface.

Fine grinding: The rough-ground steel is fine-grinded to obtain high-precision inner and outer rings and balls.

Assembly: Assemble the finely ground inner and outer rings and balls for a complete self-aligning ball bearing.

Inspection: Inspection of assembled self-aligning ball bearings to check whether they meet requirements.

Features and advantages of Self-aligning ball bearings

Self-aligning ball bearings have the following features and benefits:

Automatic alignment: Self-aligning ball bearings can automatically align the axis deviation between the inner and outer rings during operation, thereby ensuring the regular operation of the Self-aligning ball bearing.

High precision: High-precision processing equipment and manufacturing processes are used in the manufacturing process of self-aligning ball bearings, thus ensuring their high-precision requirements.

Long service life: Since self-aligning ball bearings can automatically adjust axis deviation during operation, thus avoiding problems such as bearing damage caused by axis deviation, they have a long service life.
