Abstract
A driving apparatus for an elevator includes rotary elements disposed in such a manner as to be in contact with a circumferential surface of an input shaft adapted to be rotationally driven by an electric motor device so as to rotate as the input shaft rotates, a cylindrical element disposed in such a manner as to be in contact with the rotary elements on an inner circumferential surface thereof so as to rotate as the rotary elements rotate, and a sheave provided on an outer circumferential side of the cylindrical element and configured so as to be wound therearound with ropes for lifting up and/or down a moving cage of the elevator. A brake device is disposed in a radial direction of the sheave for braking a brake disc constructed so as to extend in the radial directions and secured to the sheave.
Claims11
A driving apparatus for an elevator comprising:
- an electric motor device having a rotary plate extending radially, and a rotor fixed to an outer circumference of the rotary plate;
- an input shaft fixed to a central portion of the rotary plate, and adapted to be rotationally driven by said electric motor device;
- rotary elements, each contacting a circumferential surface of said input shaft such that the rotary elements rotate as said input shaft rotates;
- a supporting member adjacent to the rotary plate, and rotatably supporting said rotary elements;
- a cylindrical element having an inner circumferential surface contacting said rotary elements to rotate as said rotary elements rotate;
- and
- a sheave provided on an outer circumferential side of said cylindrical element to rotate together with said cylindrical element, and supported on the supporting member.
