A MULTIPLE DISC BRAKE FOR AN INDUSTRIAL ROBOT AND AN INDUSTRIAL ROBOT INCLUDING THE MULTIPLE DISC BRAKE

摘要

A multiple disc brake (10) for an industrial robot (1 ), wherein the multiple disc brake (10) includes a hub (4). The multiple disc brake (10) includes at least one friction disc (5) arranged to the hub (4) such that it rotates with the motion of the hub (4), and a braking disc (6) arranged freely rotatable to the hub (4). The braking disc (6) has at least one brake protrusion (6A, 6B) protruding in a radial direction of the braking disc (6), and an actuating arrangement (9) including an actuator (13) and a stop member (14, 16). The actuating arrangement (9) is arranged to move the stop member (14, 16) such that the stop member (14, 16) and the at least one brake protrusion (6A, 6B) becomes engaged, whereby any rotational motion of the braking disc (6) is halted and a braking force is created by friction acting between the at least one friction disc (5) and the braking disc (6).
