SAFETY CLUTCH Russian patent published in 1996 - IPC

FIELD: mechanical engineering; protection of drive members from overload when transmitting the torque. SUBSTANCE: driving clutch member 1 and driven clutch member 2 are installed on shafts to be connected. Disk is mounted on driven shaft. Disk accommodates spring 6 of clutch instantaneous disengagement mechanism. Spring 6 contributes to axial displacement of driven clutch member 3. In case of overload, driven clutch member 3 comes into meshing with cams of brake disk 5 thus reliably holding clutch members in disengaged position. EFFECT: enhanced safety. 2 cl, 2 dwg
