ABSTRACT:
A shearing wheel, and a method of assembling the same, having individually demountable cutting segments, shear knives, and an interlock key assembly to wedge adjacent shear knives together so that each shear knife shares a mounting force of the attachment bolts present on adjacent knives. The shear knives are mounted in successive abutting relation, forming a chevron-shaped aperture into which a rectangular key is wedged. A portion of each shear knife extends radially beyond the annular member. This extending portion forms a toothlike structure for feeding and ripping waste material. A support shoulder extending axially from the annular member contacts and supports the shear knives. The shear knives may be individually removed and resharpened, whereafter shims are positioned between the shear knives and the annular member to properly space the shear knives from an adjacent shearing wheel.
