FRICTION DISK (VERSIONS) Russian patent published in 2015 - IPC F16D69/04 F16D65/12 

FIELD: machine building.

SUBSTANCE: friction disk contains at metal framework with eight pockets over the outside contour of the framework and eight holes. Holes and grooves alternate over the disk circle, on which the friction pads are secured, on their friction surfaces grooves are made. Under first option on each friction surface of the friction disk from 13 to 24 grooves are made, they are repeated after each 30-15 degrees with arc length between them from 8 to 2 cm. In each pad eight grooves are in the pocket zones, and other are beyond the pocket zones and holes of the framework. Under second option on each friction surface of the friction disk from 13 to 24 grooves are made, they are repeated after each 30-15 degrees with arc length between them from 8 to 2 cm. In each pad eight grooves are in the hole zones, and other are beyond the hole zones and pockets of the framework. Under third option on each friction surface of the friction disk from 13 to 24 grooves are made, they are repeated after each 30-15 degrees with arc length between them from 8 to 2 cm. In each pad eight grooves are in the pocket zones, eight grooves are made in hole zones, and other are beyond zones of pockets and holes of the framework.

EFFECT: increased work efficiency of the friction disk due to cooling of the work surfaces of the friction pads as result of effective removal of the wear products, increased service life of the friction disk due to reduced probability of overheating and reduced probability of cracking.
