SAFETY CONNECTING DEVICE FOR ROTATION TRANSFER Russian patent published in 2015 - IPC F16D7/04 F16D43/286 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Safety connecting device includes drive and driven parts equipped, respectively, with primary means of torque transfer and secondary means of torque transfer. The safety connecting device also contains sensitive to torque disconnection means intended to disengage the front toothed rims of the primary and secondary means of torque transfer, this results in interruption of the torque transfer, when the torque transferred between two part of the connecting device exceeds the set maximum value. The sensitive to torque disconnection means include a pressure chamber filled with incompressible fluid, and valve devices ensuring the fluid output from the pressure chamber when the set maximum pressure of the fluid is exceeded in the chamber. The pressure of the fluid in the pressure chamber creates force acting on the front toothed rims of the primary and secondary means of torque transfer. The valve devices include safety valve installed at one end of the channel connecting with the pressure chamber. The safety valve is made with possibility to move between the closed position, where it closes the channel, and inlet position where it opens channel permitting the pressure chamber fluid output via the mentioned channel.

EFFECT: improvement of design.
