Abstract:
The raceway control assumption is used to determine the rolling element
attitude angle in ball bearings. There are some problems in it. A clear
understanding of the attitude angle cannot be obtained according to this
theory. Analyzing the equilibrium of the rolling element, a new method
of calculating the attitude angle is established. As contrasted with the
raceway control assumption, the new method can be applicable to all
kinds of speeds and is relative reasonable because it is based upon
mechanical analysis. A calculation example is helpful to understanding
the attitude angle well, which was difficulty to deal with.
