The Elastic Compression in the Contact Region of a Cam Mechanism General Kinematic Pair

摘要

The paper deals with the elastic compression in the contact region of a general kinematic pair. In the case of a general cam mechanism, the general kinematic pair is formed of the contact of the working surfaces of a cam and a follower. In technical practice, the contact of the cam and the follower is created by the cylinders in contact with the parallel axes for one thing and for another, by the cylinder and the three-dimensional body, which is described locally in contact with the orthogonal radii of curvature. This issue is solved on the basis of the contact mechanics. For both cases, the relations for calculating the elastic compression in the contact regions were defined. This mathematical model is verified through the experimental identification, the general kinematic pair is carried out using a testing device. The aim of the tests was to determine the mutual approach of distant points in the two three-dimensional solids in contact.
