STRESS STATE OF THE WHEEL FROM THE ACTION OF CONCENTRATED RADIAL PRESSURE ON THE ABRASIVE GRAINS

The grinding wheel is considered as an anisotropic body. To the point of the body located at a distance from the surface of the applied normal force and certain tension due to its impact. Distance equal to the height of the grinding of grain, and the forces – the normal force of cutting. Investigated the stress distribution. It is shown that the application of the material of the grinding wheel, the Poisson's ratio which is greater than zero leads to increase of maximum stress and to reduce the number of loading cycles of cutting grain before its separation from the body of the grinding wheel.
