Technical Field

Background

Bearings are an important component in contemporary mechanical devices. Its main function is to support the mechanical rotator, reduce the friction coefficient in the course of its movement and ensure its rotation accuracy, and according to the difference of friction properties of the moving element, the bearings can be divided into two main classes of rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but its radial size, vibration and noise are large and price is high compared with the sliding bearing. An angular ball bearing is one type of bearing, and can bear both radial and axial loads. Can work at a higher rotational speed. The larger the contact angle, the higher the axial bearing capacity. High precision and high speed bearings typically take a 15 degree contact angle. Under axial force, the contact angle increases. The thin-wall bearing realizes an extremely thin bearing section and also realizes miniaturization and light weight of products. The lubrication method of the bearing is divided into grease lubrication and oil lubrication.

The bearing generally consists of four parts, namely an inner ring, an outer ring, rolling bodies and a retainer, wherein the inner ring is matched with the shaft and rotates together with the shaft; the outer ring is matched with the bearing seat to play a supporting role; the rolling bodies are arranged between the inner ring and the outer ring by means of a retainer, and the shape, the size and the number of the rolling bodies directly influence the service performance and the service life of the bearing; the retainer can uniformly distribute the rolling bodies, prevent the rolling bodies from falling off, guide the rolling bodies to rotate and play a role in lubrication. The high-speed bearing is assembled by firstly assembling the inner ring, the retainer and the rolling bodies into an inner ring assembly, and then assembling the inner ring assembly and the outer ring.
