Embodiment Construction

[0064] In the subsequent description of the different embodiments of the invention, elements that correspond with respect to their function also receive the same reference symbols in the different configurations or shapes.

[0065] figure 1 A cross-sectional view of an actuating drive 1 known per se comprising an electric motor 2 is shown. The electric motor 2 positively drives the input shaft 7 of the transmission 3 via the clutch 8 . On the input shaft 7 a hollow worm 10 is mounted centrally, which drives the figure 1 The output shaft 4 is not shown, however, where the reference numeral 4 is approximately figure 1 The middle represents the position of the output shaft 4. The transmission 3 is thus formed by the input shaft 7 , the worm shaft 10 , the output shaft 4 (not shown) and further elements. During operation, an adjusting element, which is adjusted by the actuating drive 1 , is connected to the output shaft 4 , not shown.

Abstract

In order to increase the operational safety of an actuator (1) comprising an electric motor (2) and a gear, preferably a non-self-locking gear (3), the invention discloses a braking device which allows the controlled, self-actuating displacement, by means of a deceleration brake (5), of an actuating element connected to the actuator (1) via the gear (3). Preferably, the actuating element can be held in a fixed position by means of an additional holding device (6), even if the electric motor (2) fails. An actuator according to the invention (1) can be used, for example, to drive heavy sluice gates, in the event of a power failure, in a controlled free-fall operation at a constant rate of fall, or to hold them in a defined position. According to the invention, the holding device (6) and thedeceleration brake (5) can be combined in a common housing (11) to form a braking module (12) which can be designed to be used modularly with existing motor actuators (2) and gears (3) (cf. Fig. 2).

Description

technical field [0001] The invention relates to an actuating drive comprising an electric motor which drives an output shaft by means of a transmission, wherein the output shaft is coupleable or coupled to an adjusting element. [0002] The invention also relates to a brake module, which can be arranged, for example, between an electric motor and a transmission of such an actuating drive. Background technique [0003] Such actuating drives are known and are used, for example, to actuate adjusting elements such as gates, ie lowering gates, for blocking and blocking water flows or water locks. [0004] In the drive of gates, it is common for the actuating drive to be designed to be self-locking in order to prevent the gate from closing automatically in the event of a power failure. In some applications, however, it is desirable that the gate can be closed automatically in a controlled manner based on its own weight, preferably at a constant lowering speed (so-called "lower sa...
