Why radial taper roller bearings can’t work?

18 Published by admin Apr 03,2024

In general, the reasons for the radial taper roller bearings can't work can be considered and analyzed from two aspects: usage factors and intrinsic factors.The usage factors mainly refer to whether the installation, adjustment, maintenance, and repair of the radial taper roller bearings meet the technical requirements. Installation conditions are one of the primary factors in the use of tape roller bearings. Improper installation often leads to changes in the stress state between the various parts of the entire bearing, causing the bearing to operate abnormally and fail prematurely. According to the technical requirements for bearing installation, use, maintenance, and upkeep, monitor and inspect the load, speed, working temperature, vibration, noise, and lubrication conditions of the running bearings. If any abnormalities are found, immediately identify the cause and make adjustments to restore normal operation. In addition, it is also important to analyze and inspect the quality of lubricating grease and the surrounding medium and atmosphere.

The internal factors mainly refer to the three major factors that determine the quality of radial tape roller bearings, including structural design, manufacturing process, and material quality.Analysis and diagnostic techniques for causing burns in radial taper roller bearingsThe so-called burn damage state of bearings refers to the rapid heating of the raceway wheel, rolling element, and retaining frame of the bearing during rotation until discoloration, softening, deposition, and damage occur. The main reason for bearing burns is due to poor lubrication of the radial tape roller bearings, which may have used non-standard lubricants or excessive or insufficient lubricants, both of which are incorrect.Secondly, it may be due to excessive load (excessive preloading). The rotational speed is too high. The clearance is too small. There is water or other foreign objects invading. If neither of the above situations is true, then it is due to poor accuracy of the shaft and bearing box, and large deflection of the shaft.

Seeing this, I think everyone wants to know the solution. Firstly, we need to study the radial taper roller bearings lubricant and lubrication method, choose the right bearing lubricant and its dosage, and correct the selection of tapered roller bearings. Research should be conducted in conjunction with radial taper roller bearings for clearance and preloading, and to improve sealing devices. Check the accuracy of the shaft and bearing housing.
