ABSTRACT:
A machine for working generally tubular materials to perform deburring, pinch rolling and similar operations. The open end of the work is inserted over an idling roller mounted on the end of a first shaft. A second roller is rotationally driven on the end of a second shaft, and eccentric means controlled by separate (including manual) means are provided for varying the lateral clearance between the rollers to compress and effect rotation of the tubular work contemporaneously. A unique spur gear reduction arrangement includes a pinion gear on the driving NEMA C-face motor shaft which engages the larger ring gear. The ring gear is ball keyed to the shaft supporting the driven roller. An additional opening in the housing and shaft support casting is obviated, the ring gear being inserted through the motor face opening and moved laterally to engage the driven shaft over the keying ball in a driven shaft lateral bore.
