Einrichtung zur Geräuschdämpfung bei mechanischen Bremsen

摘要

The invention relates to electromagnetically operated or released friction brakes, with mechanical elements generating and transmitting the breaking force, with elastic rings, specially O rings as a means to absorb impacts or vibrations, specially noises, said rings being inserted in recesses of a mechanical element facing another mechanical element and comprising an overmeasure for producing a prestress. Such silencing should be able to work even when greater forces are brought to bear. To this end, the O rings (11) are lodged excentrically to the axis of the brakes, wherein resistant elastic plates (12) to guide the O rings (11) can be used inside the O rings (11). The silencing of impacts, vibrations and noises in such electromagnetic brakes can also be achieved by fitting electronic retarding elements in the rectifier, which serves to feed the magnetic coil.
