What are the steps to use the taper roller auto bearing?

The taper roller auto bearing is mainly used to carry the combined radial and axial loads, which are mainly based on radial loads. Compared to angular contact ball bearings, the load capacity is large and the limit speed is low. taper roller auto bearings can withstand axial loads in one direction and limit axial displacement of the shaft or housing in one direction.

Adjusting the axial clearance When installing the taper roller auto bearing, the axial clearance can be adjusted via the adjusting nut on the pivot, the adjusting disc and the thread in the bearing seat bore or via 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.

In taper roller auto 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 correspondingly larger.

For bearings with low speed and vibration, they should be installed backlash-free or with preload. The purpose is to ensure that the rollers and raceways of taper roller auto bearings have 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 is the permissible error of taper roller auto bearing?

Equivalent dynamic load

P=Fr KN] If Fa/Fr≤e

P=0,4Fr +YFa [KN] If Fa/Fr>e

When using single row taper roller auto bearings in pairs (the basic dimensions may vary), the additional axial force caused by the radial load must be taken into account when calculating the dynamically equivalent load on the bearing. The additional axial force S of the single row taper roller auto bearing can be calculated approximately according to the following formula: S= Fr/2Y

Equivalent static load

Single row taper roller auto bearings

P0=0,5Fr +Y0fa KN]

If P0 <Fr, take P0 × Fr

Two- and four-row taper roller auto bearings

P=0Fr +Y1Fa [KN] If Fa/Fr≤e

P=0,67Fr +Y2Fa [KN] If Fa/Fr>e

How do I install an taper roller auto bearing?

taper roller auto bearings are separable bearings, and the inner and outer rings can be separated. Therefore, during installation, the inner ring cage roller element arrangement can be press-fitted to the shaft in each case and the outer ring can be installed separately into the bearing seat hole. on the surface of the career.

taper roller auto bearings are usually used in pairs. When installing, you should focus on three aspects and opt for installing and adjusting the axial clearance for troubleshooting and temperature detection.
