SAFETY CLUTCH FOR ROLLING STAND MAIN DRIVE TRANSMISSIONS Russian patent published in 2009 - IPC F16D7/02 F16D1/08 

FIELD: mechanics, metallurgy.

SUBSTANCE: proposed safety clutch incorporates a rotary-sliding sleeve, its one end receiving the spindle inner thread part and axially moving, while its other end envelopes, with heavy-keying fit, the spindle part comprising inner sleeve. Note that its rear end representing a sleeve continuation forms in the case of an overload, with help of a spacer sleeve and a gap swollen by operating fluid, an yieldable friction joint ruling out the turning. The force of starting axial shift is adjusted by the cylinder pressure. Additionally the spindle threaded section can be furnished with a rigid bearing section, while the spindle section with inner sleeve can have a floating support section.

EFFECT: yieldable friction joint ruling out the turning.
