Abstract RU 2526020 C2

FIELD: machine building.

SUBSTANCE: invention refers to the field of machine-building, namely, to the friction disks. The friction disk comprises a metal frame with eight recesses along external contour of the frame and eight holes with composite friction cover plates secured thereto. The friction surfaces of the friction cover plates are provided with twelve grooves each. The frame holes and recesses alternate along the disk circumference. Four grooves are located at one of the cover plates in the area of frame recesses, while the other grooves are located beyond the area of frame recesses and holes. Four grooves are located at the other cover plate within areas of frame holes, while the rest grooves are located beyond the area of frame recesses and holes.

EFFECT: reduction of potential cracking and destruction of cover plates is achieved, which increases the disk strength and its stability to centrifugal loads.
