Detailed introduction of angular contact ball bearings
Angular contact ball bearing
(Angular Contact Ball Bearings) can support both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.
Angular contact ball bearings
Single-row angular contact ball bearings can only bear axial loads in one direction, and they will cause additional axial forces when bearing radial loads. And can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand large axial loads.
Angular contact ball bearings are non-separated design, with shoulders on both sides of the inner and outer rings varying in height. In order to increase the load capacity of the bearing, the shoulder on one side is processed lower, so that the bearing can fit more steel balls.
Double-row angular contact ball bearings can withstand large radial and axial combined radial and axial loads and moment loads, limiting axial displacement on both sides of the shaft. Mainly used to limit the axial displacement of the shaft and the shell in the two-way angular contact ball bearing. The tiltability between the inner and outer rings is limited. The allowable tilt angle depends on the internal clearance of the bearing, the size of the bearing, the internal design and the effect The force and moment on the bearing, and the maximum allowable tilt angle should ensure that no excessively high additional stress is generated in the bearing. If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing, at the same time, it will reduce the bearing running accuracy and increase the running noise.
Double-row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, care should be taken. Although the bearing can withstand bidirectional axial loads, if there is a ball gap on one side, care should be taken not to let the main axial load pass through the groove side of the gap. When using bearings, care should be taken to make the raceway on the side without the ball notch bear the main load.
Paired double ball bearings
If it is installed in pairs, the outer rings of a pair of bearings are opposite, that is, the wide end face is opposite to the wide end face, and the narrow end face is opposite to the narrow end face. This prevents additional axial forces and limits the shaft or housing to axial clearance in both directions.
Because the inner and outer rings of the raceway can be relatively displaced on the horizontal axis, it can bear both radial and axial loads-combined load (single-row angular contact ball bearings can only support axial loads in one direction, so they are often (Installed in pairs). The material of the cage includes brass, synthetic resin, etc., which are differentiated according to the bearing type and use conditions. Angular contact ball bearings are mostly manufactured by foreign bearing manufacturers. They are mostly used in imported equipment such as angular contact ball bearings 3204RS, etc. The narrow side is outside, the wide side is inside, the other wide side is inside, and the narrow side is outside. Is back-to-back contact.
