Abstract:
1. A rotary cutter for a wood planing machine, comprising: an elongated shaft that defines a rotation axis, that has two opposite mounting ends, and at least one axially extending blade-mounting surface parallel to said rotation axis and extending between said mounting ends, and that is formed with threaded holes indented inwardly from said blade-mounting surface and aligned in an axial direction relative to said rotation axis; a pair of blade-aligning members, each of which is mounted on a respective one of said mounting ends of said shaft, and each of which is formed with at least one protrusion; at least one blade attached to said blade-mounting surface and having two opposite end portions, each of which is formed with a first recess that receives said protrusion of a respective one of said blade-aligning members so as to permit alignment of said blade on said blade-mounting surface; at least one elongated blade-fastening plate attached to said blade-mounting surface of said shaft, formed with a plurality of through-holes that are respectively registered with said threaded holes in said blade-mounting surface, and cooperating with said blade-mounting surface to define a blade-receiving gap therebetween for receiving said blade therein; and a plurality of fastening screws, each of which extends through a respective one of said through-holes in said blade-fastening plate and said blade receiving gap and engages threadedly a respective one of said threaded holes in said shaft so as to fasten said blade to said blade-mounting surface of said shaft upon tightening of said fastening screws.
