Embodiment Construction

[0026] figure 1 A speed limiter 1 of an elevator installation 2 according to an exemplary embodiment of the invention is shown in a schematic perspective view. Under this instance, figure 1 Illustrated in is an arrangement in which the switching vane 3 is arranged in a neutral pivoting arrangement and also outside the cam ring 4 . The elevator installation 2 also comprises triggering ropes 5 and a car 41, which is shown in Figure 4 and be able to move in elevator shafts.

[0027] The exemplary speed limiter 1 monitors the speed of the car 41 by means of the pendulum principle. The speed limiter comprises a frame 6 and a wheel 7 mounted on the frame 6 so as to be rotatable about a support point 7a. A slot 8 is formed on the wheel 7, in which slot 8 the trigger cord 5 is guided. Furthermore, the wheel 7 has a non-circularly extending guide surface 9 . In this example, the guide surface 9 outlines a wave-like movement in radial direction during the rotation of the wheel 7 ...

Abstract

A speed limiter for an elevator installation includes a stand, a wheel rotatably mounted on the stand and a non-circularly extending guide surface rotatable with the wheel. A pendulum, which is pivotable relative to the stand, with a pendulum wheel bearing against the guide surface is provided. In addition, a restraining device is provided, which loads the pendulum wheel at least indirectly with a restraining force against the guide surface. A switching vane connected with the pendulum comes into engagement with a blocking dog, which dog is connected at least indirectly with the wheel, when the pendulum is pivoted out to a certain extent in which the pendulum wheel lifts off the guide surface. In addition, an actuating device that triggers the engagement between the switching vane and the blocking dog is provided.

Description

technical field [0001] The invention relates to a speed limiter for an elevator installation, an elevator installation with a speed limiter and a method for limiting the speed of a car of an elevator installation. Background technique [0002] A speed limiter for monitoring the travel speed of a car is known from DE 36 15 270 A1. In operation, the speed limiter works as follows: The car actuates the cable sheave of the speed limiter in a known manner via the rope, wherein the retaining ring and the cam are integrated into the cable sheave. The swing roller follows the trajectory of the cam. The check spring is set so that the pendulum roller follows the wheel of the cam up to the rated speed of the elevator. The pendulum lever is set to have pendulum motion in alternating directions via the pendulum roller and the cam. When the elevator speed exceeds a specific trigger value preset by the restraining spring, the pendulum roller lifts away from the cam. The moment of iner...
