Abstract: A weighing apparatus adapted for use in an existing conveyor, and a method for attaching a weighing apparatus to an existing conveyor without removing components or modifying the conveyor. The apparatus comprises a roller, a load cell, a vertical support and a cross member. The cross member is secured to adjacent existing idlers or alternatively to the frame supporting the existing conveyor via non-invasive means that do not require the existing conveyor or components to be removed or modified by cutting, drilling or welding. The roller is capable of precise adjustment both horizontally and vertically relative to the conveyor to ensure levelness and accuracy without the use of tools.

Abstract: Bearing hubs are typically machined in a lathe. Strict tolerances must be observed because, if the bearing fits too tightly in the hub, it may “lock up” and will not turn. An approach to relax the strict tolerances associated with these bearing hubs is to cut threads or parallel grooves (circumferentially) in the surface in contact with the outer race of the bearing. These threads or the high points between the grooves will deform (crush) when the bearing race is pressed in. The strain, then, in the bearing race is lessened due to the plastic strain of the hub, reducing the chance the bearing will lock up.

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.
