Abstract

Ina keyed shaft/hub connections, problems of fretting corrosion and backlash occurs due to slippage of keys during impact and shock loads. The solution to these problem is elimination of key by using keyless power transmission device to transmit torque. This papers reviews shrink disc as a keyless power transmission device to transmit power between shaft and hub. Shrink disc as a locking device uses interference fit to transmit torque or axial force. In this paper, review of design of these interference fit carried out by different authors by different methods like traditional method (Lame’s equation, compound cylinder theory) and numerical method is carried out. Also the comparison between these methods have been carried out. Also, design of shrink disc based on reliability and dynamic reliability has been reviewed. In this review paper, torque transmission capacity and contact stress analysis of shrink disc compiled by
different authors is carried out.
