ABSTRACT:
A retaining mechanism securely retains a gear in a fixed position on a shaft of a drive system in a photographic processor. The retaining mechanism includes a woodruff key which is held in position between the gear, preferably in a keyway in the gear, and an arcuate keyway in the shaft. The key has a first end portion which is engaged by a set screw and a second end portion which deformably engages an interior surface of the keyway of the gear. The set screw extends through a bore in the gear and has a head portion with a diameter slightly greater than the diameter of the bore. The set screw engages the first end portion of the key with its distal end, thereby tipping the key so that the second end portion of the key engages the interior surface of the keyway of the gear. The gear is made of a material, preferably an ultra-high molecular weight polyethylene, which can be initially deformed by interference with the head of the set screw and, remains deformed, effectively retaining the set screw in a fixed position. As a result, the set screw securely retains the second end portion of the key in engagement with the surface of the keyway of the gear, which in turn securely retains the gear on the shaft.
