Abstract
A method of constructing a stub shaft for conveyor pulleys, comprising forming an annular exterior periphery on an inward portion of a shaft member. Forming an annular ring with a complimentary interior peripheral surface having substantially the same dimensions as at least a portion of the annular exterior periphery of the shaft. Placing the annular ring over the shaft wherein the formed interior peripheral surface of the annular ring is in abutment with the formed annular exterior periphery of the shaft. Machining the inner side of the annular ring to be complementary to the outer side of the hub. Machining the exterior periphery of the inward portion of the shaft to a reduced diameter thereby forming an inwardly facing shoulder thereon flush with the machined inner side of the annular ring, and wherein the reduced diameter is substantially the same diameter as the opening in the hub. Bolting the annular ring to the hub, thereby preventing relative movement between the main shaft, the annular ring and the hub.
