Hertzian contact stress bearing
Witryna15 cze 2024 · 2.1 Introduction. When two elements with curved surfaces make contact with each other and are pressed together, contact stresses (also called Hertzian contact stresses) are developed within the contact areas. Practical examples include the contact between wheels and rails, valve cams and tappets, mating gears and … WitrynaTo engineer a contact condition like that the cylinder needs a profile with "end reliefs". This is true for tires, needle bearings and other roller type of devices. The simplest modification is to crown the cylinder that the contact is of double radius type, just as Hertzian theory handles.
