SPRING-LOADED BRAKE FOR AN ACTUATOR FOR DRIVING A HOUSEHOLD SCREEN AND ACTUATOR EQUIPPED WITH SUCH A BRAKE
摘要:
This spring-loaded brake (105) for an actuator for driving a household screen comprises a helical spring (30) each end of which forms a lug (32a, 32b) extending radially, a friction piece (40) comprising a friction surface (41) against which the helical spring (30) presses radially, an input piece (10) able to drive the rotation of the spring (30) about a central axis (X30) in one direction reducing the force of contact between the helical spring (30) and the friction surface, and an output piece (20) able to drive the rotation of the spring (30) about its axis in a direction increasing the force of contact between the helical spring and the friction surface. This brake (105) additionally comprises two pieces (10, 50) which always rotate as one about the axis (X30) of the spring and each of which forms an end stop (16, 57) to an axial movement of the helical spring (30). The end stop (16) formed by one of these pieces (10) is able to limit the axial movement of the spring in a first direction, whereas the end stop (57) formed by the other piece (50) is able to limit the axial movement of the spring in a second direction opposite to the first direction.
