ELECTROMAGNETIC BRAKE DEVICE FOR HOIST OF ELEVATOR

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic brake device which maintains a proper holding force generated between an elastic body and an amateur and enables easy replacement of the elastic body in a hoist of an elevator.;SOLUTION: An electromagnetic brake device 1 includes: a brake shoe 2 which may slidably contact with a drum; an amateur 3 which supports the brake shoe 2; a brake spring 4 which presses the amateur 3 and biases the brake shoe 2 in a brake direction; an electromagnetic magnet core 6 which suctions the amateur 3 against the biasing force of the brake spring 4 and separates the brake shoe 2 from the drum; and a rod 7 which is provided at the amateur 3 and guides displacement of the amateur 3. The electromagnetic brake device 1 includes: a bolt body 8 which screws into a brake shoe side end part of the rod 7 to detachably fit therein; and an elastic body 9 provided between the bolt body 8 and the amateur 3. The elastic body 9 may vary a contact area which contacts with the amateur 3 according to screwing movements of the bolt body 8.;COPYRIGHT: (C)2014,JPO&INPIT
