Abstract
A self-rotating saw tooth and associated mount assembly for use in wood cutting, for example with the saw disc on a feller buncher. Each saw tooth configured to rotate about its own axis of rotation responsive to contact with wood during cutting. A saw disc specially configured for use with the self-rotating saw teeth.
Claims14
A cutting system comprising:
- a generally circular, rotatable saw disc having a periphery and a disc plane of rotation;
- a plurality of mounting tangs evenly spaced around the periphery of the saw disc;
- a circular cutting tooth having a cutting edge to cut material as the saw disc is rotated, the cutting tooth being removably and rotatably mounted to each of the mounting tangs by a saw disc mounting system including:
- a mounting tang bore defined in each of the mounting tangs, the mounting tang bore extending generally tangentially with respect to the rotation of the saw disc and terminating at a generally radially extending tang tooth face;
- a bolt positioned within each of the mounting tang bores;
- an adaptor plate having a centrally-disposed aperture, the adaptor plate being positioned on the bolt with the bolt passing through the aperture, and having a first face abutting the tang tooth face and a second face wherein the first and second adaptor faces are inclined with respect to each other;
- a retainer that defines a retainer aperture, the retainer being positioned on the bolt with the bolt passing through the retainer aperture, the retainer being mounted in abutment with the adaptor plate;
- and
- wherein the cutting tooth is rotatably mounted to the retainer so that as the saw disc is rotated to cut material, the cutting tooth will rotate on the retainer and a different portion of the cutting edge engages the workpiece as the cutting tooth rotates while the saw disc rotates.
6 more elements
A cutting system comprising:
- a generally circular, rotatable saw disc with at least one mounting tang having a tangentially-extending bore with a bolt positioned within the bore along a bore axis;
- a circular cutting tooth having an internal opening through which the bolt extends;
- and
- a cutting tooth mounting system for mounting the circular cutting tooth to the mounting tang, the cutting tooth mounting system including:
- an adaptor plate defining a centrally-disposed aperture, the adaptor plate being positioned on the bolt with the bolt passing through the aperture, and having a first face abutting the mounting tang and a second face wherein the first and second adaptor faces are inclined with respect to each other;
- a generally conical retainer defining a retainer aperture, the retainer aperture being disposed offset with respect to the bore axis such that the retainer is asymmetrically mounted with respect to the bore axis when mounted on the bolt;
- and
- wherein the internal opening in the cutting tooth is generally conical and complementing the configuration of the retainer, the cutting tooth being rotatably and removably mounted to the retainer such that the cutting tooth is offset in such a manner that causes the cutting tooth to rotate responsive to contact with material as the saw disc rotates.
