Embodiment Construction

[0032] The tubular drive MC consists of a cylindrical outer tube 20 housing an electric gear motor 24, ie an assembly of an electric motor plus a reduction planetary gear transmission, coupled to an (optional) brake 22 of known type . Both the gear motor 24 and the brake 22 have a cylindrical shape with an axis X, the gear motor 24 having an output pin 40 rotatable about the axis X. The brake 22 and the gear motor 24 form a unit of the drive MC, here defined as the gear motor unit 10 .

[0033] The rotational motion of the pin 40 is transferred to the output shaft 86 via an Oldham coupling which compensates for any misalignment between the pin 40 and the shaft 86 . The coupling is formed by inserting a bush 42 having a beak 42a into a first slit of a second bush 52, the second bush has a second slit at a position opposite to the first slit, and the protrusion of the shaft 86 The portion 86a is inserted into this second slit. The two slots of the bushing 52 are oriented at 9...

Abstract

To reduce the noise level and the conduction of vibrations in a driver (MC) for a roller shutter comprising an outer hollow tube (20) containing a gearmotor unit (10) adapted to actuate the roller shutter, two elastic elements (60, 90) are provided that are mounted inside the tube spaced apart and each adapted to suspend the gearmotor unit inside the tube, so that between the tube and the gear-motor unit an interspace (W) is created.

Description

technical field [0001] The present invention generally relates to tubular drives for roller blinds such as curtains / blinds, curtains or combination shutters. Background technique [0002] In tubular reduction gear motors for roller blinds, one problem is noise, especially noise due to vibrations. EP 1727959 proposes various actuation structures as a solution. For example (see figure 2 ) In order to fix the electric motor to the outer cladding tube, an absorbing plate 48 is arranged between the two. This motor is coupled to a gear motor which in turn has elastic means and an adapter connecting it to the roller blind. Since the direct contact between the gear motor and the outer tube facilitates the transmission of noisy vibrations, in a more optimal solution (in the same literature Figure 4 , 5 and 6) the motor is suspended inside the tube. exist Figure 4 In a variant of , the motor is cantilevered inside the tube, with the uncomfortable consequence that it can oscil...
