BLADE AND WHEEL PLATE FOR BLAST CLEANING WHEEL AND METHOD OF CONNECTING A BLADE TO THE WHEEL PLATE

摘要

A method and apparatus for connecting a. blade to a single sided wheel plate or a pair of interconnected wheel plates. The assembly provides a repeatable, positive and even positioning location for each blade, It utilizes an ellipse that tapers outwardly from the center of the wheel along the blade connecting member that corresponds, with the connecting channel on the wheel. The ellipse provides for equal and uniform contact on the entire blade connection to firmly hold the blade in place without parallel surfaces. The ellipse design provides a measured and increasing improved release in that all. surfaces of the ellipse are tapered with non-parallel surfaces such that blade retention and blade removal is dramatically simplified.
