Tapered Roller Bearings Cage to Improvement Design

In order to improve the utilization of materials, improving stamping cage processing methods, the single row tapered roller bearing cage is improved from structural strength, puts forward whole stamping cage a type of structure. Use ANSYS finite element analysis to the different structure and the thickness cage. Get the stress contours of the cage, based on equal strength design principles. Get...

On Calculation Methods and Results for Straight Cylindrical Roller Bearing Deflection, Stiffness, and Stress

The purpose of this study was to assess some calculation methods for quantifying the relationships of bearing geometry, material properties, load, deflection, stiffness, and stress. The scope of the work was limited to two-dimensional modeling of straight cylindrical roller bearings. Preparations for studies of dynamic response of bearings with damaged surfaces motivated this work. Studies were...

Grease Degradation in R0F Bearing Tests

This paper is the second in a series that examines grease lubrication mechanisms and failure in rolling element bearings. The aim of the work was to understand the grease condition changes during use and the relationship to lubrication performance and failure. R0F bearing tests were carried out with two lithium hydroxystearate greases and the effects of the temperature, the speed, and the addit...

A Comparison of Shaft Deflection Measurements

The oldest of all the shaft specifications is flex. Once the production problems had been overcome which enabled steel shafts to become a reality, early steel shaft manufacturers began to experiment with producing shafts, which possessed different amounts of resistance to bending. Through the 70 years of shaft design that have followed the introduction of the steel shaft, companies have produce...
