2- A chain drive using bush roller chain transmits 5500 W of power. The driving shaft on an electric motor runs at 1440 r.p.m. and velocity ratio is 4.6:1. The drive is required to operate continuously with periodic lubrication and driven machine is such that load can be regarded as fairly constant. Considering the center distance to be as minimum as possible, design the chain drive by calculating leading dimensions, number of teeth and length of the chain.
