Transmission and torque-limiting joint

A torque limiting joint comprising:

• an outer member having an inner circumferential surface, said outer member defining a plurality of receptive recesses, each of said receptive recesses includes a first radial flank, a circumferential bottom portion, an inclined flank positioned at an incline to a radial direction, and a junction surface between said inner circumference surface and said inclined flank;
• an inner member positioned inside said outer member, said inner member defining a plurality of tangential seats, each tangential seat extending orthogonally to said radial direction and lying parallel to a plane orthogonal to an axis of rotation of the joint, said inner member also defining a plurality of radial glide seats extending along said radial direction, each of said plurality of glide seats extending between a periphery of said inner member and one of said tangential seats;
• a plurality of glide pads, two of said glide pads being slidably positioned in each of said plurality of tangential seats, said two glide pads in each said tangential seat having opposed surfaces with symmetrical shapings;
• biasing means for biasing said opposed surfaces of each of said two glide pads together;
• a plurality of sliders, one of said sliders being slidably positioned in each of said glide seats, each of said sliders having an inner end with a wedge shaped profile means for penetrating between said two glide pads of a respective tangential seat and part said two glide pads, each of said sliders having an outer profile means cooperating with one of said plurality of receptive recesses to transmit torque between said inner and outer member, said outer profile means includes a first radial flank, a circumferential end surface, an inclined flank positioned at an incline to said radial direction, and a junction surface positioned between said end surface and said inclined flank, said outer profile means and said receptive recess also generating an inner radial force on said slider in relationship to transmitted torque between said inner and outer member, said inner radial force moving said slider out of said receptive recess, said two glide pads and said biasing means moving a respective said slider into a respective said receptive recess below a predetermined speed difference between said inner and outer member.
