How to adjust the taper roller bearing clearance during installation?

The installation of the bearing is very important. If the installation is not proper, the whole machine will not work. How to adjust the tapered roller bearing clearance during installation?

Adjusting the axial clearance of the taper roller bearing clearance For the axial clearance of the tapered roller bearing, the adjustment nut on the journal, the adjustment washer and the thread in the bearing housing bore, or the adjustment of the preload spring can be used. . The size of the axial clearance of the taper roller bearing clearance is related to the arrangement of the bearing when mounting, the distance between the bearings, and the material of the shaft and the bearing housing, which can be determined according to working conditions.

For high-load and high-speed tapered roller bearings, when adjusting the taper roller bearing clearance, the influence of temperature rise on the axial clearance of the taper roller bearing clearance must be considered, and the taper roller bearing clearance caused by the temperature rise should also be reduced. Estimated, that is, the axial clearance should be adjusted to a larger extent.

For low-speed and vibration-resistant bearings, it is better to install without a taper roller bearing clearance, or to apply a preload. Its purpose is to make the roller and the raceway of the tapered roller bearing have good contact, and the load is evenly distributed to prevent the roller and the raceway from being damaged by the vibration shock. After adjustment, the axial clearance of the taper roller bearing clearance is checked with a dial gauge.
How to assemble tapered roller bearings and gears?

When the gear is designed, it should have an axial positioning step, and the outer ring of the bearing should be stopped. Then, the outer ring of the inner ring is locked with a lock nut, and the locking pre-tightening force is set according to the application condition, so that it can be installed.
How to install and adjust taper roller bearing clearance for tapered roller bearings?
Tapered roller bearings are generally used, face to face and back to back. The size of the taper roller bearing clearance should be determined according to the bearing size you choose and the transmission accuracy required by the mechanism. As for the adjustment method can be achieved by pressing back to loose!
