Abstract
The pinion (10) on the pin shaft (11) and/or the pinion shaft bearings to either side of the pinion and/or the pinion shaft pillow blocks (12, 13) are supported by elastically deformable components (15, 16, 22, 23) so as to automatically adapt radially in an elastically compliant manner to variations in the meshing of the pinion with the rim gear on the driven rotary drum of a tube mill or the like.
Claims6
A drive for a rim gear of a rotary drum, said drive comprising:
- a pinion (10) with drive teeth meshing with said rim gear and presenting an axial shaft receiving opening,
- a pinion shaft (11) extending through said opening and drivingly connected to said pinion (10),
- pinion shaft bearings on said pinion shaft (11) at axially opposite sides of said pinion (10),
- a pair of pinion shaft pillow blocks (12, 13) supporting said pinion shaft bearings, respectively,
- elastically deformable components (15, 16, 22, 23) disposed between said pinon (10) and said pinion shaft (11) and
- spline teeth (17, 24) formed in said opening of said pinion (10) and on said pinion shaft (11), respectively,
- said spline teeth (17, 24) being disposed axially between said elastically deformable components (15, 16, 22, 23) and being in engagement for transmission of torque.
