BRAKING APPARATUS, ELEVATOR HOISTING MACHINE THAT USES SAME, AND BUFFERING REACTION FORCE ADJUSTING METHOD FOR A BRAKING APPARATUS

摘要

In a braking apparatus, a forcing device forces a movable portion in a direction that places a friction member in contact with a rotating body. A braking force releasing device displaces the movable portion in a direction in which the friction member separates from the rotating body in opposition to the forcing device. A buffering member is disposed between a fixed portion and the movable portion, and is made of a flexible material. A deforming device deforms the buffering member by pressing the buffering member in a direction that is perpendicular to the direction of displacement of the movable portion.

主权项

1. A braking apparatus comprising:
a fixed portion; a movable portion that is displaceable toward and away from the fixed portion; a friction member that is disposed on the movable portion, and that brakes rotation of a rotating body by being placed in contact with the rotating body; a forcing device that forces the movable portion in a direction that places the friction member in contact with the rotating body; a braking force releasing device that displaces the movable portion in a direction in which the friction member separates from the rotating body in opposition to the forcing device; a buffering member that is disposed between the fixed portion and the movable portion, and that is made of a flexible material; and a deforming device that deforms the buffering member by pressing the buffering member in a direction that is perpendicular to the direction of displacement of the movable portion.
