Abstract: Generally readiness of speed increasing every field minimum time and more quality product are made the conventional system like a gear is major problem while calculating the effencing of machine the gear are required for transmission of power to input to output shaft they major power loss due to friction So that the gear replaced by the 3 or more no elbow rod having (900) bent this mechanism is called as “Gearless power transmission mechanism” is replaced of bevel gear is low cost and low Torque application are used it can be transiting angle (00to90o).it is work on kinematic chain principal and in genius link mechanism when power is transmit input shaft to output shaft ,Gearless transmission mechanism transmits power from input to output shafts by means of sliding links that form revolute pair with the hub elbow rod are slide inside the housing and power transmission take place in our project power is transmit without any gear can be manufacturing .
