Tapered Roller Bearing Installation
Adjust the axial clearance for the installation of tapered roller bearing axial clearance, can be adjusted nut on the axle neck, adjust the gasket and the thread in the bearing seat hole, or use pretension Spring and other methods to adjust. The size of the axial clearance is related to the arrangement of the bearing, the distance between the bearings, the material of the shaft and the housing, which can be determined according to working conditions.
For high load and high rotational speed tapered roller bearings, adjusting the clearance, we must consider the effect of temperature rise on the axial clearance, the temperature rise caused by the reduction of clearance, that is to say, the axial clearance should be adjusted to a larger point.
For bearings with low rotational speed and bearing vibration, no clearance should be installed or preload installed. The aim is to make the rollers and raceways of tapered roller bearings have good contact and load evenly distributed to prevent the rollers and raceways from being damaged by vibration shock. After adjusting, the axial clearance size is dial inspected.
