Abstract: Power transmission with minimum loss is the major criteria while calculating the efficiency of the machine. Most of the machines are using the gear transmission from the input to output but it has the major power loss due to friction. A research in this area brought new ideas to transmit the power using different mechanism. This paper investigates and workouts the new mechanism by replacing the bevel gear with 90 elbow is used to transmit the power. This transmission system indicates that there is the possibility of right angle power transmission without gears in efficient way. In this paper the power is transmitted with six elbows radially connected at an angle of 60 with respect to the center of the axis.
