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).

摘要： A brake (10) for an actuator (150) of an industrial robot (110) comprises a first element (20) with a plurality of legs (30) arranged at regular intervals, and a second element (90)configured to get in between a pair of legs (30) to engage the brake (10) and to thereby oppose a relative movement between the first and the second elements (20, 90), the second element (90) further being configured to get out from between the pair of legs (30) to release the brake (10) and to thereby allow a free relative movement between the first and the second elements (20, 90). The legs (30) are configured to bend aside such that the second element (90) comes in between an adjacent pair of legs (30) if braking energy needed to stop the relative movement between the first and the second elements (20, 90) exceeds a threshold value. The braking effect is dominantly based on deformation (internal friction) of the first element (20) instead of friction between the first and second elements (20, 90), and therefore a contaminant like oil does not have a strong influence on the braking effect.
