Title:
ELECTROMAGNETICALLY ACTUATABLE SPRING PRESSURE BRAKE AND METHOD FOR THE PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/049164
Kind Code:
A3
Abstract:
The invention relates to an electromagnetically actuatable spring pressure brake (100), comprising: a magnet housing (1) having a coil (2); an armature (3), which is arranged coaxial to the coil (2) and in such a way that the armature can be moved axially with respect to a shaft (7) to be braked; a friction element (5), which is spaced in a rotationally fixed manner with respect to the magnet housing (1) by means of at least one bolt-shaped connecting element (8) and which has a friction surface (5.1); a friction disk (4), which is arranged between the armature (3) and the friction element (5) and which is arranged in a rotationally fixed manner on the shaft (7) to be braked; and at least one compression spring (6), which applies pressure to the armature (3) and the spring force of which causes a braking torque on the shaft (7) to be braked in the currentless state of the coil (2) by the pressing of the friction disk (4) against the armature (3) and against the friction surface (5.1) of the friction element (5). According to the invention, for the adjustment of the distance (a) between the friction element (5) and the magnet housing (1), the at least one bolt-shaped connecting element (8) is designed having a compression zone (8.1) that can be compressed in an axial direction of the connecting element. According to alternative solutions, the compression zone can also be arranged in the region of a blind hole (9) accommodating the at least one connecting element (8) or in an accommodating opening (5.1) of a brake element (5) designed as a brake plate. The invention further relates to a method for producing the spring pressure brake (100) according to the invention.
