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.

Question

Determine the minimum required diameter of the shaft CD.

A torque of magnitude T = 1000 N-m is applied at end D of the shaft-gear system fixed at end
A (Figure 8). The two supports E and F allow free rotation of the shafts about their axes. The
diameter of shaft AB is 50 mm, the length of shafts L4B is 0.4 m and that of Lcp is 0.7 m, the
shear modulus of shafts GAB is 80 GPa and that of Gcp is 35 GPa, and the allowable shear
stress Tal is 65 MPa.

The customised shaft has a diameter of 50 mm. A square parallel key is suggested to be used for mounting a gear into this shaft. The shaft is to be made of SAE 1095 Carbon Steel with a yield stress of 572 MPa. The gear is made from SAE 1045 Carbon Steel with a yield stress of 531 MPa. A key can be made of SAE 1018 Carbon Steel with a yield stress of 372 MPa or SAE 316 Stainless Steel of 241 MPa. The gear transmits torque of 2,000 +P N-m and has a hub length of 100 mm. The design factor is chosen as 3.0 and the width of the key is 12.7 mm. Specify the keys using two materials and explain which material should be recommended in such a design scenario.
