Abstract
A sound attenuated conveyor roller assembly reduces the noise or vibration produced by the conveyor roller assembly during operation, and includes a conveyor roller having a cylindrical portion to which a sound damper may be coupled. The conveyor roller may include an unreduced outer surface and a reduced outer surface, in which the sound damper is disposed at the reduced outer surface such that an outer surface of the damper and the unreduced outer surface of the conveyor roller are located at substantially equal radial distances from a longitudinal axis of the conveyor roller. A tapered end connector having a tapered plastic tip may be coupled to each end of the conveyor roller to further reduce noise and vibration in the conveyor roller assembly.
Claims22
A sound attenuated conveyor roller assembly comprising:
- a pair of frame side walls;
- a conveyor roller comprising a cylindrical body having an outer surface, said conveyor roller coupled to said frame side walls;
- and
- a sound damping sleeve comprising a sound damping material configured to attenuate vibration at said conveyor roller during operation of said conveyor roller assembly, said sound damping sleeve coupled circumferentially around said conveyor roller and covering a majority of said outer surface of said conveyor roller, wherein said outer surface is an unreduced outer surface, wherein said conveyor roller further comprises a reduced outer surface that is located at a lesser radial distance from a longitudinal axis of said conveyor roller than said unreduced outer surface, and wherein said sound damping sleeve is coupled at said reduced outer surface.
A sound attenuated conveyor roller assembly comprising:
- a conveyor roller comprising a cylindrical body having an unreduced outer surface and a reduced outer surface;
- and
- a sound damper comprising a sound damping material configured to attenuate vibration at said conveyor roller during operation of said conveyor roller assembly, said sound damper disposed at said reduced outer surface and comprising a damper outer surface;
- wherein said damper outer surface and said unreduced outer surface are located at substantially equal radial distances from a longitudinal axis of said conveyor roller.
A method of producing a sound attenuated conveyor roller for a conveyor assembly, said method comprising:
- reducing a diameter of a damper portion of a cylindrical conveyor roller by a thickness that is twice as thick as a wall thickness of a cylindrical sound damper;
- coupling the sound damper at the damper portion, wherein the sound damper is made of sound damping material;
- and
- operably coupling the conveyor roller into the conveyor assembly.
A sound attenuated conveyor roller comprising:
- a cylindrical body having an unreduced outer surface and a reduced outer surface;
- and
- a sound damper comprising a sound damping material configured to attenuate vibration at said conveyor roller during operation of said conveyor roller, said sound damper disposed at said reduced outer surface and comprising a damper outer surface;
- wherein said damper outer surface and said unreduced outer surface are located at substantially equal radial distances from a longitudinal axis of said conveyor roller.
