shape design method of roller gear cam with relative velocity

摘要

PURPOSE: A shape designing method for a roller gear cam is provided to accurately design shape of the roller gear cam by analyzing precise contact angle and contact point of the roller gear cam using relative velocity. CONSTITUTION: A coordinate system is established by mathematically modeling a system operated through coupling of a roller gear cam with a turret. Velocity of the roller gear cam and the turret is set up. All velocities reacted for the turret is then set up. Displacement diagram of the roller gear cam is set up. The shape of the roller gear cam is designed according to the displacement diagram of the roller gear cam. A Shape design is provided by analyzing contact angle and contact point of the roller gear cam accurately using relative velocity.
