Solved Problems: Design of Shafts and Couplings
Design a clamp coupling to transmit 30 kW at 100 r.p.m. The allowable shear stress for the shaft and key is 40 MPa and the number of bolts connecting the two halves are six. The permissible tensile stress for the bolts is 70 MPa. The coefficient of friction between the muff and the shaft surface may be taken as 0.3.

Design of Shafts and Couplings
Shaft Coupling . Shafts are usually available up to 7 metres length due to inconvenience in transport. In order to have a greater length, it becomes necessary to join two or more pieces of the shaft by means of a coupling. Shaft couplings are used in machinery for several purposes, the most common of which are the following :

Design of Flange Coupling | Engineers Gallery
We know that area resisting crushing of all the bolts = n × d1 × tf. and crushing strength of all the bolts = (n × d1 × tf ) σcb. ∴ Torque, T = (n × d1 × tf × σcb ) D1/2. From this equation, the induced crushing stress in the bolts may be checked. [/nextpage] Reference by A Textbook of a Machine Design by R. S. Khurmi and J. K. Gupta

This coupling is a modification of a rigid-type flange coupling in the sense that the design of the shaft and the hub of flanges is similar to that of rigid flange coupling (see Fig. 14-17). In this, rubber bushes or leather bushes are provided to act as flexible elements, and to allow for a minor angular misalignment between the two shafts. No socket and spigot are provided on the two flanges
