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 pl...

Abstract

The invention relates to a driving device comprising a superposition transmission (18) with a planetary gear transmission (6) and a housing (8), a main drive machine ( 1), two auxiliary drives (3.1, 3.2) connected to the planetary gear (6) via a transmission connection (9.1, 10.1, 9.2, 10.2) each, the superposition transmission can be connected with the working machine (2) connected output shaft (11), wherein the planetary gear (6) has a ring gear (6.1), a sun gear (6.2), a planetary carrier (7) and a plurality of planetary gears (6.3), wherein, in the auxiliary drive Between (3.1, 3.2) and the input shaft (4) or between the auxiliary drives (3.1, 3.2) and the output shaft (5) of the planetary gear, there is an additional transmission connection with a constant transmission ratio for each auxiliary drive , the additional transmission connection is implemented in such a way that it can be disconnected or connected via each of the switching clutches (16.1, 16.2) present, wherein the auxiliary drive (3.1, 3.2) is connected to the transmission of the superposition transmission (9.1, 10.1, 9.2, 10.2) stay connected in each 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...
