ABSTRACT:
A log debarker having a frame, a stator supported by the frame, a rotor journaled in the stator for rotation about a longitudinal axis of the rotor, a rotating mechanism for rotating the rotor about the longitudinal axis, a plurality of debarking tools attached to the rotor, and a feeding system for feeding logs axially through the rotor. The feeding system includes a plurality of log gripping rollers positioned for rolling contact with the log, and individual hydraulic motors are operatively connected to the log gripping roller for rotating the log gripping roller. Each of the hydraulic motors is adapted to rotate its log gripping roller at different and variable rotation speeds to accommodate logs of uneven surfaces. A hydraulic fluid supply system supplies each of the hydraulic motors with fluid so that the different and variable hydraulic fluid requirements of each of the hydraulic motors necessitated by uneven log surfaces are satisfied. A clutch mechanism operatively disposed between the roller and a roller drive shaft is positioned in and sealed in the roller. The debarking tools are mounted in a staggered fashion relative to an incoming log and are slanted in the direction of log travel.
