ISOLATING DISCONNECTOR Russian patent published in 2013 - IPC F16D7/02 F16D41/20 

FIELD: machine building.

SUBSTANCE: isolating disconnector includes a pulley installed on the shaft by means of a bearing, a sleeve interacting with sliding with the pulley and the shaft, a one-sided coupling and a torsion spring. The one-sided coupling is fixed on the shaft and interacts with the sleeve; at that, the sleeve rotates concurrently with the one-sided coupling. The torsion spring interacts between the pulley and the one-sided coupling for elastic connection of the pulley to the shaft. The pulley is connected directly and elastically to the shaft in a temporary specified loaded state.

EFFECT: preventing overloading of a spring.
