Research Abstract

In a rolling bearing, a basic dynamic load rating and a basic static load rating are provided by the design guideline to consider the life calculation and load capacity. To improve reliability required in a machine, consideration on large load is absolutely necessary. On the other hand, it is known that several problems, for example rotational instability, are caused when the load is too small. However, there is no specific rules and regulations in terms of small load, and several empirical data and actual measured values are denoted as reference. Therefore, in this research, revolution slip of rolling element was observed. Then, necessary minimum load was studied experimentally, assuming that the necessary minimum load was defined by a load at which the rotation slip of rolling element did not increase. Consequently, it was clarified that the rotation slip of rolling element did not increase in case of equivalent load more than 0.65% of basic dynamic load rating. This condition value is similar to a recommended value as the appropriate preload. Thus, reasonability of the recommended preload was explained experimentally.
