Abstract
A conveyor screw includes a substantially continuous row of wear-resistant elements mounted on the wearing surface thereof. Opposed complementary semi-circular recesses are formed in adjacent wear-resistant elements providing a combined circular recess. A retaining member is received in each such recess and is secured to the conveyor screw with its axis positioned in the radial dividing line between adjacent wear-resistant elements. The gap between the retaining member and the wear-resistant elements is filled with a resilient padding material. In a modified form of the invention each wear-resistant element includes a backing plate of ductile material with each wear-resistant element being off-set relative to its corresponding backing plate. Adjacent faces of the backing plates, in lieu of being straight, are formed at an angle of approximately 175.degree. so as to provide a small gap permitting use of uniform components along a conveyor screw having a changing diameter.
