Both wheelswhen in positive rotation by rolling contact, will have the same ratio of velocity, or as it is generallytermed a constant velocity ratio. The number of revohitions of the shafts will beinversely proportional… … Fig. 424. secure this condition, the wheels are provided withteeth which will enable them to rotate without thepossibility of slipping.
