Assembly Of Thrust Ball Bearing

What is thrust ball bearing
Thrust ball bearing is composed of three parts: seat ring, shaft ring and ball cage assembly.The shaft ring matched with the shaft ring and the seat ring matched with the housing.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.
The purpose of thrust ball bearing
Purpose of thrust ball bearing: it is only suitable for bearing one axial load and low speed parts, such as crane hook, vertical water pump, vertical centrifuge, jack, low speed reducer, etc.The shaft ring, seat ring and rolling body of the bearing are separated and can be assembled and disassembled respectively.
Characteristics of thrust ball bearing
1. There are two types: one-way and two-way.
2. In order to allow installation errors, spherical aligning spherical seat cushion type or spherical seat ring type can be selected, either one-way or two-way.
3. Uses super clean steel which can prolong the life of the bearing.
4. High degree of grease technology can prolong the life of grease and improve the performance of bearings.
5. The use of high grade steel ball can be quiet and smooth at high speed.
6. With the ring in the option, installation error can be allowed.

Assembly of thrust ball bearing
There are two key points in thrust ball bearing assembly.One is the control of the pressing quality of the cage and the ball, the other is the control of the nominal height of the bearing after assembly.The stamping cage uses curved edge assembly die.After pressing, the steel ball is required to rotate flexibly in the pocket, but not to fall off from the pocket, and the movement of the steel ball in the pocket shall be checked according to the technical procedures.Too deep embossing of the solid cage will make the ball movement small, and the connection between the embossing convex part and the cage is too little and the strength is insufficient, which is prone to drop blocks, causing the cage to be scrapped.The size difference between the small thrust ball bearing ring and the inner diameter of the shaft ring is very small, and there is no obvious difference between the two sleeves.In order to prevent the phenomenon of mixing, that is, a set of bearings installed into the two are found to be seat rings or shaft rings.This requires certain measures.Usually with the aid of auxiliary tooling will draw ring, seat group to be distinguished, or in the nominal height of sampling with the inside diameter gauge check the inside diameter size, in order to check the inside diameter convenient, the seat ring is placed below, the shaft ring is placed above.If the inner diameter of the seat ring has obvious quenching, heating and oxidation color or does not go through grinding, it is not necessary to check the inner diameter size, and the difference between the shaft ring and the seat ring can be clearly seen, and it is not easy to mix.The nominal height of thrust ball bearing shall be measured after assembly to confirm whether it is qualified.When measuring, calibrate with height block or standard parts, and measure the load. The bearing needs to rotate for dozens of times, and must reach the minimum height.
