Rolling Bearing Life Prediction, Theory, and Application Erwin V. Zaretsky National Aeronautics and Space Administration Glenn Research Center Cleveland, Ohio 44135 Summary A tutorial is presented outlining the evolution, theory, and application of rolling-element bearing life prediction from that Equations for stress distribution in the simply supported square plate under transverse impact have been developed by using the static theory of thin plates combined with the Hertz contact law. Experimental tests were performed using an air gun to impact steel spherical projectiles on steel plates with and without Adiprene and Lexan coverings.

Bearing pressure is a particular case of contact mechanics often occurring in cases where a convex surface (male cylinder or sphere) contacts a concave surface (female cylinder or sphere: bore or hemispherical cup). Excessive contact pressure can lead to a typical bearing failure such as a plastic deformation similar to peening. A new more accurate analytical model for calculating the tooth surface contact stress of tip-relieved gears is established based on the accurate tooth profile equations represented by the parameter equations, which can be used to calculate both the standard gear and tip-relieved gear. maximum contact stress is 326.26 N/mm 2. This maximum contact stress value is almost identical with the values obtained by AGMA and Lewis equations. Table-4 compares the contact stress values obtained by using the Hertz approach, AGMA and ANSYS for different modules. The contact stress obtained

“I use HertzWin to calculate contact stiffness. My compliments for the user-friendliness and the visual feedback”. Peter, The Netherlands “I have downloaded your HertzWin program and have confirmed that your Hertz Contact Stress calculation matches what I have been using.
