ABSTRACT:
A transmission for transmitting drive from a motor to a drive sprocket wheel for driving the drive chain of a mineral mining plough has a housing which is attached to a side plate of the drive frame of a mine conveyor. The housing is formed with a recess sized and shaped to accommodate the sprocket wheel. The recess is open at one end to permit the plough drive chain to enter and leave the sprocket wheel. The housing is provided with connector flanges adjacent to the end remote from the recess opening, and with a spacer adjacent to the end adjacent to the recess opening. The spacer is detachably secured to the housing and to the drive frame, or to an intermediate channel section which joins the drive frame to a scraper-chain conveyor. The spacer and the flanges are bolted to the drive frame and/or the channel section.
