HOIST FOR ELEVATOR, AND METHOD FOR PRODUCING HOIST FOR ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2011/096079
Kind Code:
A1
Abstract:
Disclosed is a hoist for an elevator wherein a joint shaft, which is detachable in relation to the edge portion of a motor shaft, is provided with: a boss section; and a shaft section for mounting a rotation detector, which protrudes from the boss section in the direction away from the motor shaft. The shaft section for mounting a rotation detector is mounted with a rotation detector. An attachment member is provided with a through hole through which the shaft section for mounting a rotation detector is inserted. The inner peripheral surface of the through hole is formed as an inclined pressing surface which inclines along the shaft line of the motor shaft in a manner such that the inner diameter of the through hole continuously becomes larger as the through hole approaches the motor shaft. The boss section has an annular shape in which the shaft line of the joint shaft is in the center, and has an inclined receiving surface which inclines along the shaft line of the joint section in a manner such that the outer diameter of the boss section continuously becomes larger as the boss section approaches the motor shaft. The inclined pressing surface is positioned so as to be able to come into contact with the inclined receiving surface when the attachment member is displaced in the direction towards the motor shaft.
