ABSTRACT:
There is disclosed herein a drive system and a coupling system for each roller in a roller hearth kiln. The drive system is modular and encased and includes a plurality of aligned drive worms that engage driven gears that in turn rotate a drive shaft. The casing defines an oil sump which lubricates and cools the worm and gear and permits higher precision elements to be used. A cup-like ball-bearing style coupling system is used to drivingly couple the drive shaft to the roller.
