How to use tapered roller bearings?

The pressure angle of the tapered roller bearing on the raceway is variable, which allows the applied axial and radial load ratio to be balanced in any case; greater axial load capacity is achieved at larger angles.

What are the installation steps for tapered roller bearings?

Adjusting the axial clearance When installing the tapered roller bearing, the axial clearance can be adjusted by adjusting the nut on the pin, the adjusting disc and the thread in the bearing seat bore, or by using a preloaded spring. The size of the axial clearance depends on the arrangement of the bearing during installation, the distance between the bearings and the material of the shaft and bearing seat, which can be determined according to the operating conditions.

For tapered roller bearings with high load and high speed, the influence of the temperature rise on the axial clearance must be taken into account when adjusting the clearance, and the clearance reduction caused by the temperature rise must be estimated, that is, the axial clearance must be adjusted accordingly to be greater.

For bearings with low speed and vibration, they should be installed backlash-free or with preload. The purpose is to bring the rollers and raceways of tapered roller bearings into good contact, distribute the load evenly, and prevent the rollers and raceways from being damaged by vibration and shock. After setting, check the axial clearance with a gauge.

What factors should be considered when choosing tapered roller bearings?

1. Leave room

In mechanical design, generally, the size of the shaft is first determined, and then the bearing is selected according to the size of the shaft. Ball bearings are usually used for small shafts; tapered roller bearings are used for large shafts. If the radial installation space of the bearing component is limited, a bearing with a lower radial installation height should be used. Like needle bearings. Some series of deep groove ball bearings. Angular contact ball bearings. Cylindrical or spherical roller bearings and thin-walled bearings. If the axial installation space in the bearing receiving part is limited, a bearing with a smaller width can be used.

2. Bearing load

A tapered roller bearing has a higher load capacity than a ball bearing of the same shape and size and is suitable for light to medium loads. Roller bearings are suitable for carrying heavy loads.
