Inspection of thrust bearings after installation
When installing a thrust bearing, check the verticality of the shaft ring and the centerline of the shaft. The method is to fix the dial gauge to the end surface of the casing, so that the contact of the table top rotates the bearing on the bearing shaft raceway, and observes the dial gauge pointer. If the pointer is yawed, the shaft circle and the shaft center line are not perpendicular. When the case hole is deep, it can also be tested with an extended dial gauge.
When the thrust bearing is installed correctly, the seat ring can automatically adapt to the rolling of the rolling elements, ensuring that the rolling elements are located in the upper and lower ring raceways. If the installation is reversed, not only will the bearing work abnormally, but the mating surfaces will be severely worn. Since the difference between the shaft ring and the seat ring is not obvious, the assembly should be extra careful and do not make mistakes. In addition, there should be a gap of 0. 2-0. 5mm between the seat ring of the thrust bearing and the bearing housing hole to compensate for the error caused by inaccurate machining and installation. When the center of the bearing ring is offset during operation This gap ensures that it is automatically adjusted to avoid friction and normal operation. Otherwise, it will cause severe damage to the bearing.
Huatao Bearings included Rolling Bearings, Thrust Bearings, Slewing Bearings, Joint Bearings. They are widely used in Industrial Gearboxes, Electric Motors, Industrial Rollers.
