What are the structural features and performance characteristics of angular contact ball bearings?
Angular contact ball bearings are a type of bearing often used in the engineering machinery and equipment industry. They can withstand relatively complex load conditions and can also adapt to high-precision, high-speed and other usage requirements, making them the first choice for many industries. The reason why angular contact ball bearings are so popular is inseparable from their special structural characteristics. So what are the structural characteristics of angular contact ball bearings?
What is the structure of angular contact ball bearings?
1.Angular contact ball bearings consist of four parts: inner ring, outer ring, steel ball and cage. The inner and outer rings are in contact through steel balls and can withstand radial force, axial force and a certain torque. The function of the cage is to fix the steel balls, which can prevent the steel balls from falling off, and at the same time, keep the steel balls at an appropriate distance when rolling.
2.Angular contact ball bearings, as can be seen from the name, are designed with a contact angle internally, that is, there is a certain angle between the contact line between the inner and outer rings and the axis. Common contact angles are 15, 25, 45, etc., among which 15 and 25 are the main bearing types produced by Sanli Bearing. Don't underestimate this contact angle. Its size affects the bearing's load-bearing capacity and rotation accuracy. The increased contact angle means that the bearing can withstand greater axial load, but it also increases frictional resistance and causes unnecessary energy loss.
3.Single row and double row designs can be used. Single row angular contact ball bearings can only bear axial loads in one direction, but double row angular contact ball bearings can bear axial loads in both directions at the same time. In comparison, double row angular contact ball bearings have better rigidity and radial load capacity.
What are the performance characteristics of angular contact ball bearings?
1.Angular contact ball bearings have good load-bearing capacity and stiffness performance, and can withstand a large amount of radial force and axial force. When the steel ball is in rolling contact with the inner and outer rings, the load can be dispersed to reduce the stress at a single contact point and extend the service life of the bearing.
2.Angular contact ball bearings are manufactured with high precision. The precision grades of P5, P4, and even P2 are suitable for use under high-speed operating conditions. It is often used in mechanical equipment that requires high precision and high speed, such as machine tool spindles and high-speed motors.
3.Angular contact ball bearings can reduce vibration and noise generated during operation by applying preload. Preload is mainly achieved by applying axial force to the inner and outer rings of the bearing.
4.The rolling elements of angular contact ball bearings can be made of high-strength steel or ceramic materials, and the inner and outer rings are made of high-strength steel, which can reduce friction and wear. The inside of the bearing will be filled with an appropriate amount of grease to further reduce friction loss.
5.Angular contact ball bearings can be used alone or installed in pairs to meet different axial and radial load requirements.
