SAFETY CLUTCH Russian patent published in 2008 - IPC F16D7/04 F16D23/12 

FIELD: mechanics.

SUBSTANCE: invention relates to machine building and, in particular, to clutches that protect the structural components. The safety clutch contains a driving gear fitted on the shaft unfixed and a driven clutch fitted on the said shaft fixed the gear has a cavity accommodating along its inner perimeter a spring with bent ends held in the cavity by unbending force. The clutch has a bulge to interact with the spring ends during the shaft rotation. The proposed invention allows the clutch to transfer the torque in forward and reversed engine running, to drive the engine shaft up before hard coupling, to speed up to a peak load when the spring slips in the gear allowing a decrease peak loads in driving up and a protection of reduction gear components against breakage and abnormal wear.

EFFECT: decrease in starting loads in driving the engine up and protection of the reduction gear components against breakage and abnormal wear
