Abstract: A transfer drive mechanism (10, 62, 81, 116, 136, 166) for use in conjunction with work transfer apparatus is disclosed which is operative to provide extremely smooth rapid acceleration/deceleration while substantially eliminating the high stresses and potential workpiece dislocating jerk often associated with such drive systems. The drive mechanism comprises a planetary gear (26, 52, 76, 93, 128, 160, 178) having an eccentric follower means (30, 56, 80, 97, 162, 176) which is adapted to be revolved around a stationary sun gear (28, 54, 70, 88, 130, 138, 180) which imparts a rotating motion thereto.

Abstract: A deburring apparatus is provided for automatically deburring gears having a plurality of external or internal extending teeth formed therealong at predetermined intervals from each other. The apparatus comprises a frame having a spindle on which the gear to be deburred is mounted. A main shaft is rotatably supported within the frame which, upon rotation, incrementally indexes the gear mounted on the spindle for a distance corresponding to the distance between adjacent gear teeth and, after doing so, interrupts the rotation of the spindle for a predetermined period of time. Both an eccentric member and a cam are secured to the shaft. In addition a cutting tool arm is rotatably secured at one end to the eccentric member and, at its other end, a cutting tool is mounted. A bell crank is also pivotally secured to the frame and has a cam follower mounted to one end which engages the cam.
