Abstract
A motion conversion apparatus having a torque compensation device which is operable to cancel a fluctuation torque, acting on an input shaft due to an inertia load and a fluctuation torque acting on the input shaft due to a frictional load. The motion conversion apparatus converts a continuous rotational motion of the input shaft into a predetermined-type motion of an output shaft through a transmission cam device with the torque compensation device comprising a cam connected to the input shaft, a cam follower, and a resilient force-producing device pressing the cam follower against the cam. The torque compensation device is operable to cancel (a) a frictional fluctuation torque portion which is obtained by subtracting from a fluctuation torque acting on at least one of the input shaft and the output shaft when converting the motion of the input shaft into the motion of the output shaft through the transmission cam device, an average value or the approximate average value of the fluctuation torque, and (b) a fluctuation torque acting on the input shaft due to an inertia load when converting the motion of the input shaft into the motion of the output shaft.
