A conveyor drive transmission for a secondary conveyor system is disclosed. The secondary conveyor system 24 is designed to feed material cut by a mining machine onto a primary conveyor for conveyance of mined material to the rear of the machine for discharge. The secondary conveyor has afoot shaft 122 adjacent and parallel to one side of the primary conveyor. The transmission for the secondary conveyor includes an input drive shaft 131 aligned with and driven by a transverse shaft on the primary conveyor. A helical worm gear 141 mounted on and driven by the input drive shaft 131 is included to engage and drive a worm wheel 143. The worm wheel then drives a helical worm 142 mounted on a lay shaft 149 in the same plane as the input drive shaft 131. A set of bevel gears 146, 147 driven from the lay shaft 149 drives the foot shaft 122 of the secondary conveyor. Two such secondary conveyors may be provided on opposite sides of the primary conveyor, a torque sharing drive shaft being operatively connected between the lay shafts of the two transmissions. <IMAGE> |
