Procedure for determination of thrust load direction : c. If the fingers of left/right hand are pointed in the direction of rotation of driver, the thumb points in the direction of the thrust load acting on the shaft of driver. d. The direction of thrust load acting on the shaft of driven gear would be in the opposite direction to that of the driver. a. Identify the driver. b. Identify whether the helix is right hand or left hand by placing your fingers in the direction of rotation.
