Abstract

Official abstract text for this publication.

According to the present invention, a conveyor pulley for use in a belt conveyor is provided, comprising: a roller tube ( 1 ); wherein the roller tube ( 1 ) is formed by plastically deforming a central portion of a substantially cylindrical metal tube ( 2 ) radially outwardly so as to form a crowned portion ( 4 ) having an enlarged outer diameter (OD ENL ) with respect to remaining portions ( 6 ) of the metal tube ( 2 ).

First claim

Opening claim text (preview).

The invention claimed is: 1. A conveyor pulley for use in a belt conveyor, comprising: a roller tube ( 1 ) having opposite first and second longitudinal ends, first and second substantially cylindrical metal tube portions ( 6 ) adjacent the respective first and second longitudinal ends, each of the first and second substantially cylindrical metal tube portions ( 6 ) having an outer diameter (OD ORIG ), the roller tube ( 11 ) further having a plastically deformed crowned portion ( 4 ) between the first and second substantially cylindrical metal tube portions ( 6 ), the crowned portion ( 4 ) having an enlarged outer diameter (OD ENL ) that is greater than the outer diameter (OD ORIG ) of the first and second substantially cylindrical metal tube portions ( 6 ), wherein the crowned portion ( 4 ) has material thickness (t) that is substantially equal to a material thickness (t) of the first and second substantially cylindrical metal tube portions ( 6 ). 2. The conveyor pulley of claim 1 , wherein the outer diameter (OD ENL ) of the crowned portion ( 4 ) is about 0.5% to about 3% larger than the outer diameter (OD ORIG ) of the first and second substantially cylindrical metal tube portions ( 6 ). 3. The conveyor pulley of claim 1 , wherein the crowned portion ( 4 ) is substantially cylindrical and wherein first and second tapered portions ( 10 ) or first and second stepped portions are formed between the crowned portion ( 4 ) and the respective first and second substantially cylindrical metal tube portions ( 6 ). 4. The conveyor pulley of claim 1 , further comprising mounting structures for mounting the conveyor pulley to a frame of the belt conveyor.
