How to install tapered roller bearings?
For low speed and vibration bearing, should be installed without clearance or preload installation. The purpose of the utility model is to make the roller and the raceway of the tapered roller bearing generate good contact, and the load is uniformly distributed to prevent the roller and the raceway from being damaged by vibration and shock. After adjustment, the micrometer size axial clearance test. The first method is to dial fixed in the body or the bearing seat, the contact surface of the shaft of the dial to finish, along the axial direction around the push shaft, the maximum swing Yu hands
The size of the axial clearance is related to the arrangement of the bearing, the distance between the bearings, the shaft and the material of the bearing seat, and can be determined according to the working conditions. The tapered roller bearing of high speed high load, adjust the clearance, must consider the temperature effect on the axial clearance, the temperature rise caused by windage reduction estimation, that is to say, the axial clearance to adjust a little bigger.
Adjusting axial clearanceFor the installation of taper roller bearings, the axial clearance can be adjusted by the adjusting nut on the journal, the thread in the adjusting shim and the bore of the bearing seat, or by the method of pretension spring.
