Bevel gears are gears where the axes of the two shafts intersect and the toothbearing faces of the gears themselves are conically gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears .
Changing of roller wear segments for smaller mills can alternatively take place outside the mill. For the ATOX 30 and smaller, the whole roller assembly can be pulled out on a special trolley and serviced on the platform in front of the mill. Bevelhelical gear type. Bevelplanetary gear type. Easy changing of the wear segments in larger mills.
The bevel stage is the element in the drive train that is customised to the gear ratio defined by the vertical roller mill and motor speed.

RENK KPBV Vertical Roller Mill Gearbox Making mostly use of wellknown and proven components, the KPBV consists of one bevel gear stage and two planetary gear stages. Read more
power demanding vertical roller mills have been used. The first gear stage is, in all cases, a bevel gear allowing a first speed reduction and the redirection of the horizontal input axes into the vertical output axis. The further speed reduction is normally achieved by adding two planetary gear stages in series to the bevel gear stage.
