Face gears are used in angular transmissions together with one or more spur- or skew- toothed gears. In the past they were displaced by bevel gears because of the former manufacturing processes. Due to modern production processes and the improvement of these processes at WELTER zahnrad it´s now possible to produce gears with a quality index of 5 according to DIN 3967. Advantages:
Variable shaftangle from 0° to 150°
Axial relocatability enables an easy installation and a constant contact pattern under load
Triple gear sets are easy to adjustable
Ratio until i = 20
Positioning with offset
Efficiency comparable to spur gears
Bevel-spur-gear-combination is possible with only 3 parts
No temperature sensitiveness
No or a little axial force with spur gears
Separated production of crown gear and pinion – no pairing necessary
Wearless over life period
Known application range of crown gears:
Drives for human transport systems (Monorail)
Compactor adjusting for grader rollers
Rear axle drives for cars and motorbikes
Swivel mechanism for operating tables
Angular milling heads
Driven tool systems with several pinions and one crown gear
