SPRING COUPLING Russian patent published in 2017 - IPC F16D47/02 F16D43/22 F16D3/72 F16D11/06 F03D7/04 

FIELD: machine engineering.

SUBSTANCE: spring coupling comprises a drive and driven half couplings which can be moved along the shaft splines. There are cushion layers along the planes of engagement. The half coupling is connected by a helical spring. The ends of the helical spring are fixed in the slots of the couplings at the end flanges. When the shaft rotates, the spring is able to twist and move the driven half coupling, driving the half couplings into the locked-in condition. The possibility of moving the ends of the springs in the mentioned slots and the presence of shock absorbers makes the engagement smoother.

EFFECT: prolongation of working life.
