GOVERNOR FOR CONTROLLING THE SPEED OF A HOISTED OBJECT RELATIVE TO A GUIDE MEMBER

摘要

A governor includes a housing, a pulley, a belt, a first flyweight, and second flyweight. The housing defines a housing cavity. The pulley is disposed at least partially within the housing cavity. The belt is in contact with the pulley. The belt is operable to rotate the pulley at a rotational speed. The first and second flyweights are pivotably connected to the pulley, and are biased towards one another. At least a portion of the first and second flyweights are operable to move away from the pulley when the rotational speed of the pulley is increasing toward a predetermined threshold rotational speed. The first and second flyweights are operable to contact the housing, and thereby transmit rotational energy to the housing, when the rotational speed of the pulley is equal to at least the predetermined threshold rotational speed.

1. A governor operable to aid in controlling speed of a hoisted object relative to a guide member, the governor comprising:
a housing defining a housing cavity; a pulley disposed at least partially within the housing cavity; a belt in contact with the pulley, the belt being operable to rotate the pulley at a rotational speed related to speed of the hoisted objected relative to the guide member; a first flyweight and a second flyweight, the first and second flyweights being pivotably connected to the pulley, and being biased towards one another; wherein at least a portion of the first and second flyweights are operable to move away from the pulley when the rotational speed of the pulley is increasing toward a predetermined threshold rotational speed; and wherein the first and second flyweights are operable to contact the housing, and thereby transmit rotational energy to the housing, when the rotational speed of the pulley is equal to at least the predetermined threshold rotational speed.
