Do you know the installation of thrust bearing china?

The cooperation between the shaft ring and the shaft of thrust bearing china is generally a transition fit, and the cooperation between the seat ring and the bearing seat is generally a clearance fit. Therefore, this kind of bearing is easier to install, and the middle shaft ring of two-way thrust bearing china should be fixed on the shaft. to prevent rotation relative to the shaft. In addition to the general installation method of the bearing, the following points must be done:

1. Check the gap between the seat ring and the bearing seat hole of the non-rotating thrust bearing china.

There should be a gap of 0.2 ~ 0.5mm between the seat ring of thrust bearing china and the bearing seat hole to compensate for the error caused by inaccurate parts processing and installation. When the center of the bearing ring is offset during operation, the gap can be Make sure it adjusts itself to avoid touch friction to make it function properly. Otherwise, the bearing will vibrate violently.

2. Check the verticality of the thrust bearing china shaft ring and the shaft center line.

The method is to fix the dial indicator on the end face of the bearing seat, make the contacts of the meter stand on the raceway of the bearing shaft ring and rotate the bearing while observing the pointer of the dial indicator. If the pointer is deflected, it means that the shaft ring and the center line of the shaft are not perpendicular. When the casing hole is deep, it can also be inspected with an extended dial indicator head.

3. Check and adjust the clearance of the thrust bearing

There are many ways to adjust the clearance of thrust bearing china: a. Adjust the preloaded thrust bearing with gaskets; b. Adjust the preloaded thrust bearing with the nut or end cover of the bearing seat; Spring adjustment preload thrust bearing etc.

When the thrust bearing china is installed correctly, its seat ring can automatically adapt to the rolling of the rolling elements, ensuring that the rolling elements are located in the raceways of the shaft ring and the seat ring. If it is reversed, not only the bearing will not work properly, but also the mating surfaces will be severely worn. Special attention should be paid to the fact that the difference between the shaft ring and the seat ring is not obvious, so extra care should be taken during assembly, and no mistakes should be made.
