  • Electric motor with epicyclic gear system
    Patent number: 6500087
    Abstract: An electric motor (1) or drive motor has a cylindrical, possibly, however, even conical or disk-shaped rotor (2) and a cavity or interior space (4) surrounded by the rotor (2) and/or its stator (3), into which protrudes in the installed position an epicyclic gear system (5) or planetary gear system which is driven by the electric motor (1). The electric motor (1) has a toothed power output element, for example, a cantilevered gear shaft (6), with which meshes an opposing-teeth-exhibiting power input element, for example, the planetary gears (7) of the epicyclic gear system (5).

  • Gear drive, especially planetary gear drive, with pressure equalization
    Patent number: 6471614
    Abstract: Gear drive (1), for example, a planetary gear drive, having a housing (2) and at least one shaft (4), for example, an output shaft leading through the housing wall (3) toward the outside. For equalization of pressure, a pressure-equalization chamber (5) is positioned in the interior of the shaft (4) and/or a drive part (6) associated therewith and is connected, on the one hand, with the interior of gear drive (1) and, on the other hand, with the external atmosphere, for example, via a borehole (11) running through shaft (4) so that the shaft (4), which has to pass through the housing (2) of the gear drive (1), is employed in equalization of pressure. Located in the pressure-equalization chamber (5) is a membrane (7) that is deformable via pressure differentials. The membrane separates and seals the external atmosphere and the interior of the gear drive from each other.
