Embodiment Construction

[0039] figure 1 An embodiment of the device according to the invention is shown. A plurality of drive units 1 according to the invention are provided which together drive a ring gear 2 . Each drive unit 1 comprises a motor 3, in this embodiment a hydraulic motor. Alternatively, other motors, in particular electric motors, can also be used. Each drive unit also includes a transmission and an output shaft, which are mounted in a common housing 10 . Arranged in each case on the output shafts is a pinion 6 , which meshes with the ring gear 2 . Teeth 7 of the pinion 6 meet teeth 8 of the ring gear. The drive unit 1 can be mounted on the device via a mounting flange. The ring gear 2 is a ring structure and has a plurality of teeth 8 on its outer side. The ring gear may also include an internal ring gear.

[0040] exist figure 1In the shown embodiment, 3 drive units are provided for the ring gear 2 . As an alternative, however, it is also possible to use only one or two driv...

Abstract

This invention relates to a drive unit for driving a ring gear, comprising a motor, a transmission and a drive shaft, on which a pinion is arranged for driving the ring gear, wherein the drive unit includes a mechanical overload protection. In accordance with the invention the overload protection is arranged between the transmission and the pinion.

Description

technical field [0001] The invention relates to a drive unit for driving or braking a ring gear comprising a motor or brake, a transmission and an output shaft on which a pinion is arranged for driving the ring gear. Background technique [0002] Such a drive unit is used, for example, to drive a swivel or pivot device, in particular to drive a swivel device of a wind turbine or a swivel or pivot device of a crane or excavator. The ring gear has a plurality of teeth on its outer or inner circumference, which mesh with the teeth of the pinion gear. The ring gear is driven by driving the pinion gear through the output shaft. Ring gears are also used to drive winches, especially those used to drive cranes. [0003] To drive the ring gear, multiple drive units can also be used in parallel when high drive forces are required. [0004] For such drive units, overload protection mechanisms are known, for example in the form of slip clutches or predetermined breaking points, which...
