  • Driving device for a mining machine
    Patent number: 4234234
    Abstract: The invention solves a problem of transferring the combine weight onto a veyor through a railing, instead of through a link chain.For the aforesaid purpose a slide skid is provided, at both sides, with riding wheels. During operation of the combine the riding wheels roll on a railing; the riding wheels are mounted in a slide skid on a cranked axle. The cranked axle is protected against turning by means of a cover provided with a splined hole fixed on a splined pin of the cranked axle. The cover is fixed to the slide skid by means of screws.The design of the present device prevents deformation and tightening of vertical links of a chain between a rack and a slide skid in case of fouling of the rack with fine coal.
