Document Type and Number:
Japanese Patent JP2015074535
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable an operator to easily correct an orientation of an electric motor when tension is applied to a belt by moving the electric motor while the belt is installed on a drive pulley and a driven pulley.SOLUTION: A drive device for an elevator includes a base member 10 and fastening devices 40, 50 which threadably mount leg parts 20, 30 provided on an electric motor 1 on the base member 10 respectively. The fastening device 40 includes an eccentric bolt 41 and a nut 42. The eccentric bolt 41 has a head part 41a, a concentric cylindrical part 41b which concentrically extends from the head part 41a, an eccentric cylindrical part 41c which eccentrically extends from the concentric cylindrical part 41b, and a male screw part 41d which concentrically extends from the eccentric cylindrical part 41c. The leg part 20 has a round hole 22a, and the base member 10 has a long hole 13a which extends in a direction perpendicular to a rotation shaft 1a of the electric motor 1. The eccentric bolt 41 makes the concentric cylindrical part 41b press an inner peripheral surface of the long hole 13a of the base member 10 and makes the eccentric cylindrical part 41c press an inner peripheral surface of the round hole 22a of the leg part 20 to move the leg part 20 in a direction intersecting the long hole 13a.
