Abstract
A conveyor drive transmission for a secondary conveyor system is disclosed. The secondary conveyor system is designed to feed material cut by a mining machine onto a primary conveyor which would convey mine material to the rear of the machine for discharge. The secondary conveyor has a foot shaft adjacent and parallel to one side of the primary conveyor. The transmission for the secondary conveyor includes an input drive shaft aligned with and driven by a transverse shaft on the primary conveyor. A helical worm drive gear mounted on and driven by the input drive shaft is included to engage and drive a worm wheel. The worm wheel then drives a helical worm gear mounted on a shaft in the same plane as the input drive shaft. A set of bevel gears mounted on the same shaft as the helical worm driven gear drives the worm shaft of the secondary conveyor.
