2.1 General description
The gearbox is supplied with one, two or three transmission stages.
The gearbox is suitable for various mounting positions. Observe the correct oil level.
Housing
The housings for sizes 18 and 28 are made of die-cast aluminum. The housings for
sizes 38 to 208 are made of cast iron.
Geared components
The geared components of the gearboxes are hardened. In the case of helical worm
gearboxes the worm is hardened and ground, and the gear is manufactured from bronze.
The bevel gear stage of the bevel helical 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 by means of dip
lubrication or oil spray lubrication. Bearings that are not supplied with lubricant are closed
and grease-lubricated.
2.2 Shaft seals
The radial shaft sealing ring, combination shaft sealing ring, labyrinth seal, and slide ring
seal at the shaft outlet prevent lubricant from escaping from the housing and impurities from
entering it.
Radial shaft sealing ring
At higher ambient temperatures over +40 °C to +80 °C, shaft sealing rings made from
temperature-resistant material are used, subject to contractual agreement.
The radial shaft sealing ring is used as the standard type of seal. It is provided with an
additional dust lip to protect against contaminants from outside.
