ABSTRACT
In Chapter 10 of the first volume of this handbook, equations were developed to calculate rolling
element orbital speed and speed of the rolling element about its own axis. These equations were
constructed using kinematical relationships based on simple rolling motion. Also, as discussed in
Chapter 6 of the first volume of this handbook, when a load occurs between a rolling element and
raceway, a contact surface is formed. When the rolling element rotates relative to the deformed
surface, the simple rolling motion does not occur; rather, a combination of rolling and sliding
motions occur. Hence, a system of complex equations needs to be developed to calculate the
rolling element speeds.
