How to install and align the girth gear and pinion prmdrive

Jan 14, 2020  The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Backlash (engineering) - Wikipedia

In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts.It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."

LGDX lateral gear drive for ball mills

Jun 17, 2020  Two fundamentally different philosophies exist to drive horizonal mills: While the gear unit and the electric motor of a central drive are located at the front of the mill and take up a lot of space, the lateral drive is placed at the side of the mill. The three-stage spur gear unit includes a mechanical torque split and contributes significantly to the extremely compact setup.
