Problems solved by technology

This cannot be prevented by a clutch on the auxiliary drive, although this would even allow the auxiliary drive to be protected by disengaging, but then the speed of the planet carrier still rises rapidly
It is proposed in the prior art to prevent this by means of a brake on the planet carrier, however, additional components for the coupling are still required
This increases the cost of the drive equipment and requires more space, two serious disadvantages

Embodiment Construction

[0062] figure 1 shows a drive device according to the invention, which is coupled to the working machine 1 via an output shaft 15 . And on such a device, the method for limiting the rotational speed according to the invention can be advantageously used. The superposition gear 17 has a housing 9 and includes a planetary gear 18 with a gear ratio i_PG. The input shaft 14 connects the main drive machine 2 with the ring gear 4 of the planetary gear, and the output shaft 15 connects the sun gear 7 with the working machine 1 . The third shaft of the superposition transmission is formed by the auxiliary drive shafts 16.1 and 16.2. These auxiliary drive shafts connect the auxiliary drives 3 . 1 and 3 . 2 to the planetary carrier 10 via the first transmission stages 6 . 1 , 6 . 2 . The planetary carrier 10 carries the planetary gears 5 via planet pins on the one hand, and on the other side the planetary carrier is designed as a gear which forms the first transmission stage 6 with co...

Abstract

The invention relates to a drive device comprising a superimposed transmission (17), a main drive machine (2) connected to an input shaft (14) of the superimposed transmission, at least one auxiliarydrive (3.1, 3.2) and an output shaft (15) of the superimposed transmission which can be connected to a working machine (1), the superimposed transmission (17) comprising a planetary gear system (18) with a ring gear (4), a sun gear (7), a planet carrier (10) and a plurality of planet gears (5), and the input shaft (14) being connected to the ring gear (4), the output shaft (15) being connected tothe sun gear (7) and the at least one auxiliary drive (3.1, 3.2) being connected to the planet carrier (10) via a first gear stage (6.1, 6.1a, 6.1b, 6.2, 6.2a, 6.2b) with a constant gear ratio (i_SG1), an additional driving connection with a constant gear ratio (i_SG1, i_SG2, iSG3) being provided between the auxiliary drive (3.1, 3.2) and the ring gear (4) or a pinion (4.1) on the input shaft, anda switchable clutch (11.1, 11.2) being provided in said additional driving connection which can activate or interrupt the additional driving connection such that in the event of an interruption by the clutch (11.1, 11.2), the connection between the auxiliary drive (3.1, 3.2) and the planet carrier (10) via the first gear stage (6.1, 6.1a, 6.1b, 6.2, 6.2a, 6.2b) remains activated.

Description

technical field [0001] The invention relates to a driving device, which comprises: a superposition transmission device a main drive machine connected to the input shaft of the superposition transmission; one or more auxiliary drives; and an output shaft which may be connected to the working machine, wherein the superposition transmission comprises a ring gear, a sun gear, A planetary transmission of a planet carrier and a plurality of planet gears, and wherein the input shaft is connected to the ring gear, the output shaft is connected to the sun gear, and one or more auxiliary drives are connected to the planet carrier via a transmission stage. [0002] Furthermore, the invention relates to a method for limiting the rotational speed of a main or auxiliary drive in the event of a failure or rapid shutdown of such a drive. Background technique [0003] In a superposition transmission, the two shafts of the planetary transmission are usually driven by mutually independent dr...
