ABSTRACT:
An accumulation type roller conveyor drive assembly comprising a sprocket and drive wheel unit rotatably supported on a tubular cylindrical bushing mounted in a housing formed by separate upper and lower portions. These housing portions have sides formed with abutting surfaces lying in a common plane passing through the axis of the bushing, with semicircular recesses engageable with peripheral end portions of the bushing, and with interfitting tabs and recesses for positioning the housing portions in assembled relation. An axle bolt, insertable through openings formed by semicircular apertures in the sides of the housing portions concentric with their respective recesses, and through a central passage in the bushing, receives a nut which when tightened, clamps the sides of the housing portions between the axle bolt head and nut and the bushing ends, thereby locking the drive assembly components in assembled condition.
