FRICTION DISK COOLING GROOVES

摘要

A friction disk for a frictionally acting device includes an annular friction surface having an inner edge and an outer edge. Grooves are formed in the friction surface. The grooves include a plurality of radially extending inner grooves which communicate with the inner edge. A plurality of radially extending outer grooves communicate with the outer edge. A plurality of branch grooves communicate each inner groove with a pair of the outer grooves, and communicate each outer groove with a pair of the inner grooves. Each inner groove is aligned with a corresponding outer groove. Each branch groove intersects with another of the branch grooves. Each inner groove has a width which is greater than a width of a corresponding outer groove.

1. A friction disk for a frictionally acting device, comprising:
a circular plate having a surface to which friction material is fixed to define an annular friction surface having an inner edge and an outer edge; a plurality of radially extending inner grooves formed in the friction surface, each inner groove communicating with the inner edge and being equal angularly spaced from each other along the inner edge; a plurality of radially extending outer grooves formed in the friction surface, each outer groove communicating with the outer edge and being equal angularly spaced from each other along the outer edge; a plurality of groove branches located in an annular region of said friction disk between said plurality of radially extending inner grooves and said radially extending outer grooves, said plurality of groove branches communicating each inner groove with a pair of the outer grooves, and said groove branches communicating each outer groove with a pair of the inner grooves.
