An overspeed governor (1) for an elevator, comprising: a sheave (2) and a cam (4) mounted on one side so as to rotate together with the sheave (2); a pendulum member (5) mounted on the frame (25) so as to rotate about a pivot point (6) and provided with a tripping pawl (8); a cam driven wheel (3) mounted on the pendulum member (5) so as to follow the contour of the cam (4) when the sheave (2) rotates, and starting to jump at intervals when the rotational speed of the sheave (2) is greater than a first rotational speed; a plurality of engaging portions (9) arranged on one side of the sheave (2) so as to rotate together with the sheave (2), the engaging portions (9) and the pendulum member (5) being arranged such that the tripping pawl (8) engages one of the engaging portions (9) when a second rotational speed of the sheave (2) is reached; a main resistance element (23) mounted between the frame (25) and the pendulum member (5); at least one additional resistance element (12) acting on the pendulum member (5) starting from a third intermediate rotational speed of the sheave (2).
一种用于电梯的超速调速器(1),包括:槽轮(2)和凸轮(4),凸轮(4)安装在一侧以便与槽轮(2)一起旋转;摆锤构件(5),安装在框架(25)上以便围绕枢转点(6)旋转,并且设有脱扣棘爪(8);凸轮从动轮(3),安装在摆锤构件(5)上以当槽轮(2)旋转时跟随凸轮(4)的轮廓,并且对于槽轮(2)的旋转速度大于第一旋转速度时,凸轮从动轮(3)开始间隔地跳跃;多个接合部(9),布置在槽轮(2)的一侧以便与槽轮(2)一起旋转,接合部(9)和摆锤构件(5)布置成使得在达到槽轮(2)的第二旋转速度时,脱扣棘爪(8)接合接合部(9)中的一个接合部;主阻力元件(23),安装在框架(25)和摆锤构件(5)之间;至少一个附加阻力元件(12),其从槽轮(2)的第三中间旋转速度开始作用于摆锤构件(5)。
