What is thrust ball bearing
Thrust ball bearing is designed to withstand thrust load when running at high speed and is composed of washer-like rings with ball rolling raceway groove. Because the ring is in the shape of seat, thrust ball bearings are divided into two types: flat base cushion type and aligning spherical cushion type. In addition, these bearings can withstand axial loads but not radial loads.
Thrust ball bearing classification
According to the force, it is divided into unidirectional thrust ball bearing and bidirectional thrust ball bearing. One - way thrust ball bearing, can bear one - way axial load. Bidirectional thrust ball bearing, can withstand bidirectional axial load, wherein shaft ring and shaft match. The mounting surface of the seat ring is spherical bearing with self-aligning performance, which can reduce the influence of installation error. Thrust ball bearing can not bear radial load, limit speed is low.
Material analysis of thrust ball bearing
1.Thrust ball bearings generally use steel as the main material, but not all steel is suitable for this kind of mechanical hardware fittings. Bearing steel is generally used, because it will be more ideal. Bearing steels have high and uniform hardness and wear resistance, as well as high elastic limits. Bearing steel has strict requirements on the uniformity of chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides, etc. It is one of the most stringent steel types in all steel production, and it is also a kind of material commonly used in thrust ball bearings.
2.Thrust ball bearing is a kind of separation bearing. The shaft ring and seat ring can be separated from the components of the cage and steel ball. The shaft ring is a ring matched with the shaft, the seat ring is a ring matched with the bearing seat hole, and there is a gap between the shaft; Thrust ball bearing can only bear axial load, one-way thrust ball bearing can only bear axial load in one direction, two-way thrust ball bearing can bear axial load in two directions; Thrust ball bearings can not limit the radial displacement of the shaft, and the limit speed is very low. One-way thrust ball bearings can limit the axial displacement of the shaft and the shell in one direction, and two-way bearings can limit the axial displacement in two directions. Thrust roller bearings are used to bear combined axial and radial loads, which are mainly axial loads, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction coefficient, higher speed and self-aligning performance.
