Adjusting the axial clearance for the installation of tapered roller bearings can be achieved by adjusting the nuts, washers, and threads in the bearing seat holes on the shaft neck, or by using methods such as pre tightening springs. The size of axial clearance is related to the arrangement of bearings during installation, the distance between bearings, and the material of the shaft and bearing seat, and can be determined based on working conditions.

For high load and high speed tapered roller bearings, when adjusting the clearance, it is necessary to consider the impact of temperature rise on the axial clearance, and estimate the reduction in clearance caused by temperature rise. In other words, the axial clearance should be appropriately adjusted to be larger.

For bearings with low rotational speed and bearing vibration, installation without clearance or with preload should be adopted. The purpose is to create good contact between the rollers and raceways of tapered roller bearings, distribute the load evenly, and prevent the rollers and raceways from being damaged by vibration and impact. After adjustment, the size of the axial clearance is checked with a dial gauge.

Installation method of thrust tapered roller bearings

Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low speed situations, while thrust tapered roller bearings have slightly flat speeds. Thrust bearings mainly bear axial loads in assemblies and are widely used. Although the thrust bearing installation operation

How are gears and tapered roller bearings assembled?

When designing gears, there should be axial positioning steps to lock the outer ring of the bearing tightly, and the outer side of the inner ring should be locked with a locking nut. The pre tightening force for locking should be set according to the application conditions.

How to install and adjust the clearance of tapered roller bearings?

Generally, tapered roller bearings are used, both face-to-face and back-to-back, and the clearance size should be determined based on the size of the bearing you choose and the transmission accuracy required by the mechanism! As for the adjustment method, it can be achieved by pressing and loosening!
