Drive device i.e. unbalance drive, for driving sieving body of sieving machine, has bearing units exclusively arranged at horizontal shafts in axis direction of shaft section between unbalance units and supported at crossbar

摘要

The device has a synchronous gear (3) staying in effective connection with a drive motor (1') and including output shafts (4, 5). Unbalance units are arranged in a horizontal direction between side walls (6') of a sieving body (6) and has horizontal shafts that are supported at a crossbar (21) by bearing units. The unbalance units are directly arranged at the horizontal shafts. The bearing units are exclusively arranged at the horizontal shafts in an axis direction of a shaft section between the unbalance units and supported at the crossbar.
