Abstract

Belt tension is manually adjusted by disengaging two toothed plates in one direction and then moving one of the plates transverse to that direction. This permits tightening or loosening of belt tension and facilitates removal and replacement of the belt.

Belt Tension Adjustment

Belt tension is manually adjusted by disengaging two toothed plates in one direction and then moving one of the plates transverse to that direction. This permits tightening or loosening of belt tension and facilitates removal and replacement of the belt.

Referring to Fig. 1, belt tension is maintained by a shaft-mounted idler retained in a slotted fixed plate by spring tension against a movable plate. The shaft and movable plate are anchored together. Mating sawteeth on opposing faces of the plates prevents transverse (T) motion of the shaft and idler as long as the spring holds the plates together. Longitudinal motion of the shaft in one direction (L) separates the plates to permit transverse adjustment of the idler.

Figs. 2A and 2B show two versions of belt tension adjustment. In version A, the plates are released by pushing on the idler end of the shaft. The opposite end of the shaft is pushed to release the plates in version B.
