エレベータの巻上機、及びエレベータの巻上機の製造方法

Japanese Patent JP5300990

B2

In an elevator hoisting machine, a coupling shaft that is mountable to and removable from an end portion of a motor shaft has: a boss portion; and a rotation detector mounting shaft portion that protrudes outward from the boss portion away from the motor shaft. A rotation detector is mounted onto the rotation detector mounting shaft portion. A penetrating aperture through which the rotation detector mounting shaft portion is passed is disposed on a mounting member. An inner circumferential surface of the penetrating aperture is an inclined pressing surface that is inclined relative to a shaft axis of the motor shaft such that an inside diameter of the penetrating aperture increases continuously toward the motor shaft. An inclined bearing surface that is inclined relative to a shaft axis of the coupling shaft is disposed on the boss portion so as to be formed into an annular shape around the shaft axis of the coupling shaft, and such that an outside diameter of the boss portion increases continuously toward the motor shaft. The inclined pressing surface is able to contact the inclined bearing surface by the mounting member being displaced toward the motor shaft.
