Problems solved by technology

However, the chain steering method in this case is also not conducive to the installation of the chain.
[0004] In known actuators with a rigid chain at the back, the installation of the chain takes up a lot of space and causes some wear depending on the specific thrust direction

Embodiment Construction

[0037] figure 1 The shown actuator 1 comprises a box-shaped housing 2, a pushable back rigid chain 3 and a joint head 4 with a ball joint for rotational placement. As an alternative to the joint head 4 with a spherical joint, it is also possible to provide numerous other fastening options for the actuator 1 . It can also be placed directly on the housing 2 . The back rigid chain 3 retracts and extends from the front end or front side 5 of the housing 2 . A joint head 4 with a spherical joint is screwed onto the rear end or rear side 6 of the housing 2 . An electrical connection socket 7 for power supply is also provided on the rear side 6 . The casing 2 also includes a front panel 8 , an end panel 9 and a shield 10 screwed on the bottom panel 11 with a U-shaped cross section.

[0038] The housing 2 comprises a load-bearing structure which, in addition to a front panel 8 and an end panel 9 parallel thereto, also includes a bottom panel 11 . The load-bearing structure also ...

Abstract

The invention relates to an actuator with a rigid-spined chain, a drive motor, and a worm which can be driven by the drive motor and which comprises a helical groove. The rigid-spined chain has engagement means and is guided along the worm, and the chain is in engagement with the worm by means of the engagement means and the helical groove in order to drive the rigid-spined chain. Such an actuatoris to have a more compact design and should optionally exhibit less wear. For this purpose, the core diameter of the worm is larger than twice the distance from the motor axis to the motor face alongwhich the rigid-spined chain is guided, and the rigid-spined chain is guided at least partly along the drive motor by means of the engagement means.

Description

technical field [0001] The invention relates to an actuator with a rigid back chain, a drive motor and a screw with a helical groove drivable by the drive motor, wherein the rigid back chain has snap-in members and is guided along the screw And by means of the engaging member and the helical groove engaging with the screw rod, so as to drive the rear rigid chain. Background technique [0002] DE 20221581 U1 discloses an actuator which moves a back rigid chain by means of a motor-driven spindle. Such actuators are used, for example, to open and close casements. The electric motor is associated with a transmission and primarily drives the spindle in the motor extension. The installation of the chain is likewise mainly carried out in the electric motor extension along the main shaft, with which the chain engages. The stroke movement of the actuator is carried out substantially perpendicular to the spindle centerline. For this purpose, the rear rigid chain is deflected and g...
