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.

8.9 (A/B). A solid steel shaft of 200 mm diameter transmits 5 MW at 500 rev/min. It is proposed to alter the horsepower to 7 MW and the speed to 440 rev/min and to replace the solid shaft by a hollow shaft made of the same type of steel but having only 80% of the weight of the solid shaft. The length of both shafts is the same and the hollow shaft is to have the same maximum shear stress as the solid shaft. Find: (a) the ratio between the torque per unit angle of twist per metre for the two shafts; (b) the external and internal diameters for the hollow shaft. [L.Mech.E.] [2.085; 261, 190 mm.]

As part of an innovation policy introduced within the company to research into newer design of swings, the R and D department is proposing that work should be carried out on motorized swings. The initial consideration is to use an electric motor to spin the central shaft. For this purpose a hollow shaft of diameter ratio 3:5 is required to transmit 600 kW at 110 rpm, the maximum torque being 12% greater than the mean. The shear stress is not to exceed 60MPa and the twist in a length of 3m is not to exceed 1 Degree (1º). Calculate the minimum outer diameter (D) to satisfy both these conditions. Take G = 80GN/m2
