Increased operational reliability through continuous checking of girth gear and pinion clearance.
Optimisation of your mill drives and kiln drives
POLGUIDE is a future-oriented girth gear and pinion drive in which the girth gear and pinion always have the same clearance, both in radial and axial direction. This ensures optimal meshing of the teeth under all operating conditions. All rotary kilns can be equipped with our drive system, irrespective of the number of stations.
Optimal meshing conditions and low wear
POLGUIDE ensures optimal meshing conditions and low wear, because it reliably compensates all disturbances caused by the operating conditions. For this purpose, a self-aligning pinion is fitted to the movably-mounted pinion shaft. Moreover, we have designed the base plate of the girth gear and pinion such that the pinion constantly follows the radial movement of the girth gear. In order always to keep the radial and axial clearance the same, the girth gear and pinion are each equipped with two guide rings.
With POLGUIDE, you can implement two-support kilns with greater length/diameter ratios than is the case with the classic girth gear/pinion concept. Furthermore, in the case of three-support and multi-support kilns, our drive concept significantly increases the service life of the girth gear and pinion.
