ABSTRACT:
An air-seal cooling fin system in a log debarker of the type having a frame, a ring mounted for rotation on the frame, and air-pressure actuated debarking arms carried on the ring. Pressurized air is supplied to the arms through a rotary air seal composed of a stationary seal portion joined to the frame and a rotatable seal portion joined to the ring including a pair of spaced annular elements disposed on axially opposed sides of the stationary portion. Arranged on each of the annular elements in the rotatable seal portion is a circular array of angularly spaced fins. These fins act to radiate heat generated in the seal during debarker operation and interact with a circular array of fins carried on the stationary portion to create cooling air turbulence in the region of the seal.
