エレベータの調速機
Document Type and Number:
Japanese Patent JP5735504
Kind Code:
B2
Abstract:
A governor system for an elevator is disclosed. The governor includes a shaft horizontally extending from a sheave of the governor system. A base, spring, and slider are mounted on the shaft with linkages extending from the base of the sheave to at least one flyweight. The spring and flyweights are sized such that centrifugal force will be sufficient to overcome the biasing force of the spring upon the sheave reaching a certain rotational speed. Overspeed sensors and mechanical switches are positioned proximate the flyweights and flyweights plates such that upon such motion of the flyweights, the governor system is triggered, thereby slowing and ultimately stopping the elevator. The governor system has a greatly reduced space requirement compared to previous governors, as well as a reduced likelihood of false trips due to acceleration or deceleration of the car.
