Abstract

PURPOSE: To reduce adverse influence on operation property which is caused by a vibration moment, by mounting a large friction wheel rotatively coupled with a driving sheave, and a small friction wheel mounted at a small type motor which is activated in the event of emergency, and coupled with a large friction wheel through the work of an operating device.
CONSTITUTION: A large friction wheel 7 formed by bent circumferential edge of a metal sheet, such as thin steel sheet, etc. is rotatively coupled with a driving sheave 3. The edge part, on which a high friction material such as rubber, etc. is sticked, is formed in a circular cone 7a. A small friction wheel 9 is fitted on an output shaft of a small type motor 8 and has a circular cone 9a facing the circular cone 7a. In the event of a power failure, the small friction wheel 9 is displaced through the work of an operating device 10, and the circular cones 7a and 9a of the two friction wheels 7 and 9 respectively contact each other, whereby a power of the small type motor 8 is transmitted. In consequence, an adverse influence on the operation property of an elevator can be decreased by the large friction wheel 7 having a small vibration moment.
