Abstract:
In the case of power transmission sometimes a fluctuating or repetitive load comes on drive shaft or driven shaft in working condition. At that time shaft as well as gear or pulley which is mounted on the gear shaft also comes under the fatigue loading. To determine the shaft diameter under dynamic condition we should consider length of shaft, diameter of pulley and gear, tension on pulley, rpm of shaft, distance between gear and pulley, pulley and bearing on which shaft is mounted, permissible stress of shaft material and fatigue load. The main purpose of writing of this paper is to determine shaft diameter with different material and under the different permissible stress
