Problems solved by technology

In this case, mechanical and electrical components (e.g. the planet carrier) can undergo unacceptably high rotational speeds and damage these components
Clutches in the prior art can only be protected against overspeed by decoupling the auxiliary drive

Embodiment Construction

[0035] figure 1 The drive device according to the invention is shown in plan view, which is coupled to the work machine 2 via an output shaft 11 . The work machine 2 can be, for example, a pump, a compressor, a ventilator or a blower. The work machine can also be a belt drive or a mill or similar. Especially for work machines 2 with high power, it is especially important to have a high-efficiency drive. Due to the dimensions of the drive, it is also crucial that the required installation space is not too large.

[0036]The superposition gear 18 present in the drive unit has a housing 8 and includes the planetary gear 6 . The output shaft 5 of the planetary gear is at the same time the output shaft 11 of the superposition gear. The input shaft 4 connects the main drive machine 1 to the ring gear 6.1 of the planetary gear, and the output shaft 5 is coupled to the sun gear 6.2. The transmission connection between the ring gear 6.1 and the sun gear 6.2 is realized via the pla...

Abstract

The invention relates to a drive device which comprises a speed modulation gearbox (18) having a planetary gearbox (6) and a case (8), a main drive machine (1), connected to an input shaft (4) of thespeed modulation gearbox, two auxiliary drives (3.1, 3.2), each connected to the planetary gearbox (6) via a drive connection (9.1,10.1, 9.2,10.2), and an output shaft (11) of the speed modulation gearbox, which output shaft can be connected to a drive machine (2). The planetary gearbox (6) comprises a ring gear (6.1), a sun gear (6.2), a planet carrier (7) and a plurality of planet gears (6.3). The auxiliary drives (3.1, 3.2) and the input shaft (4) or the auxiliary drives (3.1, 3.2) and a power take-off shaft (5) of the planetary gearbox have an additional drive connection with a constant transmission ratio per auxiliary drive. Said additional drive connection is designed such that it can be engaged or disengaged by means of a respective shifting clutch (16.1, 16.2), the drive connections (9.1, 10.1, 9.2,10.2) from the auxiliary drives (3.1, 3.2) to the speed modulation gearbox remaining engaged in any case.

Description

technical field [0001] The invention relates to a drive device comprising a superposition transmission with a planetary gear and a housing, a main drive machine connected to the input shaft of the superposition transmission, two drive machines connected to the planetary transmission via a transmission connection each An output shaft of an auxiliary drive device, a superposition transmission device that can be connected to a working machine, wherein the planetary gear transmission has a ring gear, a sun gear, a planet carrier and a plurality of planetary gears. Background technique [0002] In the case of a superposition transmission, usually at least two shafts of a planetary gear are driven by mutually independent drives, so that the rotational speeds of the other shaft (output shaft) are added or subtracted. If one of the drive devices can be controlled, a stepless speed regulation of the output shaft can be realized. In this case, two shafts are driven, one of which is d...
