Embodiment Construction

[0029] figure 1 The braking system 1 shown in includes a partially shown seat body 2 which is fixed to a main structure (not shown). In the seat body 2 there is a rotatable shaft 3 with an axis X and a pulley for driving the elevator cable. One end of the shaft 3 has two grooves 4 and 5 .

[0030] In the example described, the braking system also comprises two brakes 8 and 9, respectively comprising discs 11 and 12, the hubs of which, when turning therewith, are able to engage respectively in the grooves 3 and 4 along the axis X of the shaft. Swipe up.

[0031] Friction linings 13 are provided on the periphery and side surfaces of the brake discs 11 and 12 .

[0032] The brakes 8 and 9 also comprise respective movable armatures 15 and 16 guided in translation along the axis X by a strut 17 of the first brake and a strut 18 of the second brake, which struts 17 and 18 are screwed into the respective brake 8 and 9 of the yokes 19 and 20.

Abstract

The present invention relates to a braking system for an electric motor, the braking system comprising: a chassis; and at least one brake supported by the chassis, the brake comprising: at least one brake disk connected via a fluted connection to a shaft driven by the motor; an armature that is movable in translation along an axis of rotation of the shaft; a plurality of armature-guiding spacers, at least one of the spacers being engaged at one end in a corresponding housing in the chassis, so as to enable the chassis to take up torque that is exerted on the brake during braking; a plurality of springs for urging the armature against the disk; and an electromagnet which, when powered, attracts the armature and moves it away from the disk against the action of the springs.

Description

field of invention [0001] This invention relates to motor braking systems, and more particularly to motor braking systems for use with drive elevators or other lifting systems. Background technique [0002] The known braking system includes electromagnetic brakes, each of which includes a brake disk fixed on a motor shaft and provided with a friction lining, and an armature movable under the drive of an electromagnet. If the electromagnet is not energized, the armature is spring-loaded against the friction lining, thereby applying a braking torque to the disc and a reaction force to the brake and the seat supporting it. [0003] The brake is usually assembled to the base body in a bolt-fixed manner, and at the same time, due to the friction generated by tightening the bolts, the brake torque is locked by the base body. [0004] Screw-fastened devices are subject to a large dispersion of properties, which necessitates oversizing the braking system by using more screws and / or...
