A self-locking core and shaft assembly includes an elongate generally cylindrical metal shaft having a plurality of spaced elongate upraised bosses extending substantially the entire length thereof. The spaced bosses define a plurality of spaced channels that also extend substantially the entire length of the shaft. The shaft carries an elongate hollow generally cylindrical core having a plurality of spaced inwardly projecting elongate bosses that extend substantially the entire length of the core and define a plurality of elongate spaced channels that also extend substantially the entire length of the core. The shaft and core are sized such that the core fits tightly on the shaft to inhibit rotary movement of the core with respect to the shaft. The core is made of material resistant to water absorption such as reinforced fiberglass or plastic. Hollow retaining rings and spacers are also provided and shaped to fit tightly onto the shaft which has longitudinal markings to assist in the proper positioning of the core and retaining rings and any spacers used.
A self-locking core and shaft assembly comprising an elongate generally cylindrical solid shaft having an exterior surface and opposite end portions, said shaft having a plurality of spaced laterally protruding first bosses formed in said exterior surface and extending longitudinally substantially the length of said shaft, said spaced first bosses defining elongate first channels therebetween, said first channels extending substantially the length of said shaft, a hollow elongate generally cylindrical core having an interior surface and an exterior surface, said interior surface formed of a plurality of inwardly protruding second bosses extending substantially the length of said core, said spaced second bosses defining second channels extending substantially the length of said core, said core sized to be tightly fitted over and in contact with said exterior surface of said shaft to minimize movement of said core with respect to said shaft.
A self-locking core and shaft assembly comprising an elongate generally cylindrical solid shaft having an exterior surface and opposite end portions, said shaft having a plurality of spaced laterally protruding first bosses formed in said exterior surface and extending longitudinally substantially the length of said shaft, said spaced first bosses defining elongate first channels therebetween, said first channels extending substantially the length of said shaft, a hollow elongate generally cylindrical core having opposite end portions and having an interior surface and an exterior surface and being substantially the same length as said shaft, said interior surface having formed thereon a plurality of inwardly disposed second bosses that extend substantially the length of said core, said spaced second bosses defining second channels extending substantially the length of said core, said first bosses fitting into said second channels and said second bosses fitting into said first channels to provide that said core fits tightly onto and in contact with said exterior surface said shaft to minimize rotary movement of said core with respect to said shaft.
A self-locking core and shaft assembly comprising an elongate generally cylindrical solid shaft having an exterior surface and opposite end portions, said shaft having at least one laterally protruding first boss extending longitudinally substantially the length of said shaft, a hollow elongate generally cylindrical core having an interior surface and exterior surface, said interior surface formed of at least one channel extending substantially the length of said core, said core sized to be tightly fitted over and in contact with said exterior surface of said shaft to minimize movement of said core with respect to said shaft.
