A worm gear mount of a type used in slide projectors includes a shaft, a pair of bearings supporting the shaft, a drive wheel on an end overhang of the shaft extending beyond one of the bearings, a worm gear on the shaft betweeen the bearings, and a gear wheel rotatable on an axis perpendicular to the shaft and meshing with the worm gear. The bearings are formed with generally U-shaped openings that face toward the gear wheel, and the openings allow the shaft to be moved into the bearings from the region occupied by the gear wheel. The gear wheel serves ...
A worm gear assembly comprising bearing support means, two bearings supported by said support means in axially spaced relation to each other, each of said bearings having a shaft-receiving recess of substantially U-shaped configuration open at one side, the open sides of both bearings being faced in the same direction, a first shaft mounted in said recesses of said bearings, a worm gear on said shaft between said bearings, a second shaft spaced from and extending in a direction approximately perpendicular to said first shaft, and a gear wheel on said sec...
