Abstract:
A transmission, comprising:an input shaft; at least two cam followers; at least one camming device contoured to provide substantially constant linear speed to each of said at least two cam followers through each stroke of each of said at least two cam followers, in line contact with said at least two cam followers and coupled to said input shaft; at least two levers each coupled to at least one of said at least two cam followers in a manner that causes said at least two levers to pivot in an oscillating manner upon rotation of said input shaft, said at least two levers oscillating out of phase; at least two one-way clutches each coupled to one of said at least two levers where movement of said at least two levers causes corresponding rotational movement of at least one of said at least two one-way clutches; and an output shaft coupled to said at least two one-way clutches, said at least two one-way clutches capable of causing substantially ripple free rotation of said output shaft.
