The machinery brake comprises an armature part (60) movably supported through at least two supporting points (P1, P3) on a frame part (50). Spring means (70) pushes the armature part away from the frame part and electromagnet means (80) pulls the armature part towards the frame part. Each supporting point comprises a longitudinal support pin (200) surrounded in the armature part by a sliding bearing having a flange seating against the outer surface of the armature part and in a gap (G) between the armature part and the frame part by a damper plate seating against the flange and in the frame part by a recess. The armature part is movable via the sliding bearing on the support pins. The flange and the damper plate, which is bendable into the recess, act as damping elements between the armature part and the frame part.
该机械制动器包括电枢部件(60),该电枢部件通过至少两个支撑点(P1,P3)可移动地支撑在框架部件(50)上。弹簧装置(70)将电枢部分推离框架部件,而电磁装置(80)将电枢部分朝向框架部件拉动。每个支撑点包括纵向支撑销(200),该纵向支撑销(200)在电枢部件中由滑动轴承围绕,该滑动轴承的凸缘抵着电枢部件的外表面安置并且在该电枢部件和框架部件之间的间隙(G)中,阻尼板在抵着凸缘安置并且通过凸缘在框架部件中。电枢部件可通过支撑销上的滑动轴承移动。凸缘和可弯曲到凹部中的阻尼板充当电枢部件和框架部件之间的阻尼元件。
