Performance Evaluation and Analysis of Three Pin Constant Velocity Joint

Presently Oldham's coupling and Universal joints are used for parallel offset power transmission and angular offset transmission. The basic function of a power transmission coupling is to transmit torque from an input shaft to an output shaft at a given shaft speed and where necessary to accommodate shaft misalignment. These joints have limitations on maximum offset distance / angle /speed and result in vibrations and low efficiency (below 70%). The three pin constant velocity joint is an alteration in design that offers up to 15 mm parallel offset and 12 degree angular offset, at high speeds up to 2000 or 2500 rpm @ 90% efficiency. This design lowers cost of production, space requirement and simply technology of manufacture as compared to present CVJ in market.
