Replaceable sprocket wheel assembly for modular link belt systems
First Claim
1. A part for a sprocket wheel assembly for mounting upon a drive shaft for a modular link belt, wherein the assembly has separable sprocket wheel parts removably positioned about the drive shaft in a configuration permitting removal of the sprocket wheel parts from an in-situ drive shaft in a direction perpendicular to the shaft comprising in combination:
- a sprocket wheel sectorial part for mating with a drive shaft to interfit with a further sprocket wheel sectorial part to thereby constitute a unitary sprocket drive wheel assembly of substantially cylindrical peripheral shape having sprocket teeth disposed circumferentially thereabout for driving said belt,said sprocket wheel part having interfittable flanges thinner than said wheel extending near the wheel circumference from two interfitting sector extremities disposed substantially radially inwardly toward the shaft, said flanges being adapted to meet mating flanges on said further sprocket wheel part in an overlapping mated joint to form a complete sprocket wheel disposed about an axis.

Abstract
Sprocket wheels for modular plastic link belts are made in two mating halves for expediting removal perpendicularly away from a coaxial drive shaft about which they are supported without disassembly of the shaft. To assure axial alignment and stability of the mating parts overlap joints between the parts are formed by securing together in surface contact laminar flange extensions from respective sprocket wheel halves joined in driving relationship about an inner shaft to form a completed sprocket wheel assembly. For critical use in food and chemical environments, the entire sprocket assembly is made of plastic, including binding clamps for holding the two mated flange surfaces of different halves together.

12. A sprocket wheel comprising in combination,
two mating parts each adapted (a) to mate on a drive shaft (b) to move toward and away from the shaft in a direction perpendicular to the shaft (c) to mate at circumferentially disposed flanges in surface contact with mating flanges on a mating part, and substantially radially disposed interlocking structure accessible from the sprocket wheel circumference comprising a bore and a rod for binding the flanges together in said surface contact.
-
14. A sprocket wheel comprising in combination,
two wheel parts at circumferential positions thereon respectively having inwardly extending flat planar flanges mated in driving relationship on a driving shaft to produce a circumferential portion comprising two overlapping flange joints on the respective parts to form a unitary sprocket wheel.
