Design of Shafts and Shaft Components

The shaft is basically defined as the machine element that rotates, is in circular cross-section, it is majorly used to transfer the power from one part of the system to another, or from a power generating machine to a power absorbing machine. The shaft is supported on bearings and is rotated with the help of a set of gears or pulleys that are used for the power transmission. Bending moment, torsion, and an axial force act upon the shaft. Designing of shaft primarily involves determining stresses at a critical point in the shaft that is arising due to loading.

A 0.75" diameter solid steel shaft is connected by the steel bolted coupling shown. The maximum allowable shear stress in the steel is 18 ksi (shaft and bolts). The coupling consists of steel bolts that are 1/8" diameter and the bolt holes are equally spaced and centered on a 4" diameter circle (2" radius from the center of the shaft to the center of a bolt hole). Determine a) The maximum torque that the shaft can carry Ans: /,491"* b) The number of bolts required for the torque in part a). Assume the bolts fail by shearing at the coupling interface and the shear stress is uniform across the bolt's cross sectional area.
