Abstract
A conveyor roller having a spring loaded telescoping tubular axle with tapered hexagonal shaped ends allowing quick replacement in the side frame openings of a conveyor when the openings are worn to an oversize. The tapered hex ends also provide for a tight fit between hex ends and hex holes in the frame to lessen relative motion (rattling) between the two surfaces that causes wear and noise. The roller can be installed from either side of the conveyor because the axle is collapsible from either end.
Claims22
A roller for a conveyor comprising:
- (a) a continuous telescoping roller shaft adapted to be non-rotatably mounted in opposed mounting openings, in a conveyor frame, and
- (b) a cylindrical roller tube rotatably mounted on the shaft,
- (c) wherein the shaft extends within the roller tube continuously between the opposed conveyor frame openings and comprises telescoping tubular members having tapered spindles on their outer ends, said tapered spindles adapted to engage said opposed frame openings, and resilient means positioned in one of the tubular members and urging the tubular members apart, the tubular members being telescoping to shorten the roller shaft and permit its insertion into a conveyor frame and extensible to seat the spindles in the frame openings.
A conveyor assembly comprising:
- (a) a pair of parallel laterally spaced frame members having a series of opposed sets of longitudinally spaced openings therein,
- (b) roller assemblies mounted between the frame members, each roller assembly including a tubular roller and a telescoping tubular shaft positioned within the roller tube and extending continuously between a set of opposed frame openings, said shaft having spindles on the ends non-rotatably positioned in said set of frame openings, said tubular roller being rotatably mounted on the shaft, and
- (c) wherein the shaft comprises telescoping tubular members having tapered spindles on their outer ends, said tapered spindles adapted to engage said opposed frame openings, and resilient means positioned in one of the tubular members and urging the tubular members apart, the tubular members being collapsible to shorten the roller shaft and permit its insertion into a conveyor frame and extendible to seat the spindles in the frame openings.
A roller for a conveyor comprising:
- (a) a telescoping roller shaft adapted to be non-rotatably mounted in opposed mounting openings in a conveyor frame,
- (b) a cylindrical roller tube rotatably mounted on the shaft, wherein the shaft comprises telescoping tubular members having tapered spindles on their outer ends, said tapered spindles adapted to engage opposed frame openings, the tubular members being telescoping to shorten the roller shaft and permit its insertion into a conveyor frame and extensible to seat the spindles in the frame openings, the spindles having shanks fixed in the outboard ends of the tubular members, and
- c) a helical spring positioned in the larger tubular member between the smaller tubular member and the larger tubular member urging the tubular members axially apart.
A conveyor assembly comprising:
- (a) a pair of parallel laterally spaced frame members having a series of opposed sets of longitudinally spaced openings therein,
- (b) roller assemblies mounted between the frame members, each roller assembly including a telescoping tubular shaft having spindles on the ends non-rotatably positioned in the frame openings and a tubular roller rotatably mounted on the shaft,
- (c) wherein the shaft comprises telescoping tubular members having tapered spindles on their outer ends, said tapered spindles adapted to engage opposed frame openings, the tubular members being collapsible to shorten the roller shaft and permit its insertion into a conveyor frame and extendible to seat the spindles in the frame openings, the spindles having shanks fixed in the outboard ends of the tubular members, and
- d) a helical spring positioned in the larger tubular member between the larger tubular member and the smaller tubular member urging the tubular members axially apart.
