Gearbox type
Helical gearbox
Parallel shaft gearbox
Bevel gearbox B
Bevel gearbox K
Helical worm gearbox C Aluminum
Geared components
The geared components are hardened and ground.
For the helical worm gearbox, the worm is hardened and ground. The gear is manufactured
from high-quality bronze.
The bevel gear stage of the bevel gearbox is lapped in pairs.
Lubrication
The geared components are supplied with adequate lubricant by means of dip lubrication.
Shaft bearings
All shafts are mounted in roller bearings. The roller bearings are lubricated using splash
lubrication or oil-spray lubrication. Bearings that are not supplied with lubricant are closed
and grease-lubricated.
Shaft sealing rings
The shaft sealing rings on the output side prevent lubricant from escaping from the housing
at the shaft outlet and prevent pollution from entering the housing.
The optimum use of the seals depends on the ambient conditions and the lubricant being
used.
