Dynamic Characteristics of Cylinder Push in Bearing Cylindrical Roller Detection System
Aiming at the problem that there is no dynamic analysis of the roller pushing process during the measurement of cylindrical roller dimensions,the model of the cylindrical roller push process is established based on the working principle of the ...

Squealing of cylindrical roller bearings.
Large-sized cylindrical roller bearings often emit high level squealing in grease lubrication. There are many studies on the squealing sound of the cylindrical roller bearing, however, comprehension of this sound is far from complete. We have measured sound pressure, acceleration of outer race, the roller/race slip behavior, and sound intensity. A main

Tolerance Design of Logarithmic Roller Profiles in Cylindrical Roller Bearings
A logarithmic profile is essentially optimal crowning geometry for rolling machine elements such as bearing rollers and raceways. Although some design methods of the profile have been proposed, they do not refer to the tolerance of the geometry required in engineering applications and in production.

Failure Analysis of a Cylindrical Roller Bearing Caused by Excessive Tightening Axial Force
The premature failure of a cylindrical roller bearing took place during service, with a total operation time of 100 h. The failure cause was analyzed by macroscopic and microscopic observation, metallographic analysis, hardness testing, tightening axial ...

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.
