Handling your Sandex

1. Operating theory

SANDEX units operate based on the following principal. A globoidal cam is mounted onto the input shaft. This cam interlocks with the turret portion of the output shaft. The turret has cam followers along its perimeter, which are in contact with the tapered ribs on the cam. This contact or pressure is called the preload. Turning the input shaft rolls the cam followers along the rib surfaces thereby rotating the turret according to the curve of the cam. The turret is motionless when the ribs are parallel with the edges of the cam although the cam followers stay in motion.

Two of three cam followers are always kept pressed against the tapered ribs to ensure an accurate transmission of rotation. Any backlash or movement between the tapered rib surfaces and cam followers can cause vibrations, noise, and also damage the cam and cam follower surfaces. Backlash can be completely eliminated by rotating the eccentric flange that holds the input shaft, and minimizing the distance between the input and output shaft.
