Determination of stresses in a gear disk under transverse bending with an axisymmetric load

Abstract

The need to study stresses in gear disks arises when the wheel is subjected to axial forces during operation. In this case, we are dealing with a plane stress state, characterized by the magnitude of radial and tangential stresses at various points along the radius of the disk. Experimental study of stresses in a disk under static loading of a real sample is possible if the wheel's own weight is used as a load. As a support surface, one can use: 1) the end plane of the rim, loading the disks with the weight of the shaft and partially with the own weight of the disks; 2) the plane of the flange, loading the disks with the weight of the rim and partially with the own weight of the disks. The first position occurs when the wheel is freely supported on the rim, the second - when the wheel is suspended by the shaft.
