The Hertzian problem for the ring layer of the optional thickness subject to friction forces in the contact area
The paper presents a problem-solving procedure for the contact interaction of solid cylinder with elastic ring layer, coating the contact parallel hole in the rigid body. It is supposed that the radial contact pressure varies according to the cosine law, and the friction forces in the contact area vary in proportion to radial contact pressures. The authors defines explicitly the dependence of contact area size on the resultant load and cogging performance, which appears to be very useful for engineering practice.
