1 | Materials | All torque-bearing gearbox components are made of top-quality
casehardened and tempered steels. |
2 | Gearbox structure | All sun gears and planet wheels are case-hardened and ground. The
ring gears are made of high-strength tempered steel, which is also
used for the forged planetary supports. Well thought-out
construction principles ensure an even load distribution of the
individual stages and therefore a high performance density. In addition, the gearboxes are characterised by an integral design optimised to reduce the number of components to a minimum, thereby also minimising the number of sealing points. |
3 | Bearings | All rotation parts run on rotation element bearings .Ball bearings
are used to support the input gearing,cylindrical Roller Bearings
for the planet wheels and tapered Roller Bearings are used on the
output gearing . |
4 | Seals | Travel drives and winch drives use floating oil seals, slewing
drives use rotating glyd ring seals. |
