Abstract

The invention regards a gear box, which gear box comprises a plurality of gear wheels supported on gear shafts, whereby the gear shafts are supported by rolling bearings, the rolling bearings are spherical roller bearings or optionally spherical roller bearings and toroidal roller bearings, and at least one of the rolling bearings are sealed by sealing elements on each axial end face of the at least one rolling bearing.(Figure 1)

Description

ln an embodiment, the sealing elements of the rolling bearings in the gear box function as a filter. ln an embodiment, the gear box is a gear box in any of: - a crane, - a wind turbine, - a generator, - a steel mill, - a paper mill, - an elevator, - or any other industrial application where a gear box is used. ln an embodiment, the sealing elements of the rolling bearings in the gear box function as a filter. ln an embodiment, the gear box is a gear box in any of: - a crane, - a wind turbine, - a generator, - a steel mill, - a paper mill, - an elevator, - or any other industrial application where a gear box is used.
