FIELD: mechanical engineering.
SUBSTANCE: coupling contains two parts, connected to each other by destroyed element. One of parts of coupling is implemented in the form of bush, rigidly fixed on driving or driven shaft. The other part of coupling is connected to, correspondingly, driving or driven element and is joined to bush by bearing assembly. Bearing assembly includes two bearings, and bush is implemented with doughnut. Between mentioned bearings it is located spacer ring. Destroyed element can be implemented, for instance in the form of disk from elastic material or elastic rod, between bearing and connected to destroyed element.
EFFECT: excluding of vibrations and beatings of device in case of destroy of destroyed element and to increasing of safety.
