For any kind of bearings, matching and clearance control are very important, which naturally includes tapered roller bearings. Regardless of the conditions, it is necessary to adjust the fit and clearance of tapered roller bearings reasonably. What factors should be considered when adjusting?

On the one hand, the change of temperature and hardness of tapered roller bearings should be considered, because the change of clearance is closely related to it. On the other hand, the effect of centrifugal force should also be considered, which will also change the shape of various aspects. In order to ensure the stable operation of tapered roller bearings, timely adjustment is needed.

However, under high temperature conditions, it is very difficult to coordinate and control the clearance to achieve the accuracy and performance of tapered roller bearings. In addition to the above two principles, there are many factors to be overcome.

For example, to ensure that the deformation of tapered roller bearing raceway after installation is very small, and the amount of interference fit can not be too large; but also to lubricate the bearing well, select the appropriate lubricant and lubrication measures.

When considering the clearance of tapered roller bearings, not only the aforementioned factors, but also the influence of the axial thermal elongation of the clearance should be considered. It is required that the clearance of tapered roller bearings should be accurate under working conditions.

Since the purpose of sliding bearings is to reduce internal friction, the relative displacement of internal and external rings and the adjustment method of axial clearance of ball bearings should not be used to avoid adverse effects.

Material properties are also one of the key factors to be considered, especially when the material gradually becomes soft, a little improper may cause permanent deformation of tapered roller bearings, so it must be handled with caution.
