Abstract
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 (ODENL) with respect to remaining portions (6) of the metal tube (2).
Claims4
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 (ODORIG), 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 (ODENL) that is greater than the outer diameter (ODORIG) 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).
