Abstract
In an emergency brake mechanism of the present invention, a rotation input shaft is increased in rotation speed by a planetary set-up gear to centrifuge weights, so that through the action of the centrifugal force of the weights, linings of the brake shoes are brought into press-contact with a fixed portion, to reduce rotation of the rotation input shaft, such that a large braking power is produced for a compact emergency brake mechanism.
Claims3
An emergency brake mechanism comprising a planetary set-up mechanism provided between a rotation input shaft and a fixed portion;
- weights;
- and brake shoes, wherein the brake shoes are so arranged on the rotation input shaft as to be in association with it and the weights are centrifuged by an increased rotation speed produced by the planetary set-up gear, so that through the action of the centrifugal force of the weights, friction surfaces of the brake shoes are brought into press-contact with the fixed portion, to reduce rotation of the rotation input shaft.
