The elevator speed limiter comprises a base, a connecting shaft is movably connected into the inner wall of the base, rope wheels are fixedly connected to the two sides of the surface of the connecting shaft, involute grooves are formed in the inner sides of the rope wheels, throwing balls are arranged at the left ends of the inner sides of the rope wheels, and the surfaces of the throwing balls are movably connected with the inner walls of the involute grooves. The right end of the inner side of the rope wheel is fixedly connected with a trigger device. Due to the fact that the involute groove is formed in the rope wheel, and meanwhile the throwing ball is installed at the inner end of the involute groove, when the rope wheel rotates in an accelerated mode, the throwing ball overcomes frictional resistance to move outwards along the involute groove under the action of outward centrifugal force in the involute groove, and when the throwing ball moves to the position of the trigger device, the speed limiter can be triggered in time to act, and the speed limiter is prevented from being damaged. When the triggering device is used for speed limiters with different speeds, only the installation position of the triggering device needs to be adjusted, so that the speed limiters from low speed to high speed achieve the purpose that the same rope wheel can be completely triggered.

    本发明公开了一种电梯限速器,包括底座,所述底座内壁的内部活动连接有连接轴,所述连接轴表面的两侧均固定连接有绳轮,所述绳轮的内侧开设有渐开线槽,所述绳轮内侧的左端设置有甩珠,所述甩珠的表面与渐开线槽的内壁活动连接,所述绳轮内侧的右端固定连接有触发装置。本发明由于绳轮上开设有渐开线槽,同时甩珠安装于渐开线槽的内端,当绳轮加速转动时,甩珠在渐开线槽中受向外的离心力,沿渐开线槽克服摩擦阻力向外运动,当甩珠运动到触发装置位置时,可以及时触发限速器动作,在用于不同速度的限速器时,只需要调整触发装置的安装位置即可,使得在低速到高速的限速器实现同一绳轮达到全部的可触发目的。
