FreeChat09.12.2004 I would like to incorporate the formulae into a conveyor design computer program. 6th December 2004, 11:36. Graham Shortt. Hello Derek, I would suggest the the curve radii as presented in CEMA are still valid and very much in use today. We most certainly use them, as well as the Goodyear system as presented in their Red Book. I would suggest that the belt modulus is one of the more

FreeChat09.12.2004 CEMA also gives a formula r=12(b/12) to prevent buckling at centre for convex curves. I seem to remember someone saying once that the overstress equation is not particularly good when the belt tension gets up near the rated tension of the belt.

FreeChatUse the function. f ( x) = ( x 1 − x) 2 y 0 + 2 ( x 1 − x) ( x − x 0) h + ( x − x 0) 2 y 1 ( x 1 − x 0) 2. The h is a free parameter. You can adjust its value between 1 2 ( y 0 + y 1) and y 1. If ( x 0, y 0) = ( 0, 0) and ( x 1, y 1) = ( 1, 1), as in your picture, then this f simplifies greatly. It just becomes.

FreeChat13.01.2005 I'd like to get some idea of the formulas typically used for say stockpile yard belts with convex vertical curves. My understanding is that the minimum radius is calculated to prevent overstress at belt centre, and minimum tension at the edge of the belt. The ones I've seen are from suppliers such as Dunlop (old), Goodyear, Apex, and the CEMA formulas.

FreeChatHorizontal curves eliminate the constraints of the straight line conveyor and reduce the installed and operating cost of the conveyor. Horizontally curved conveyors use conventionally troughed conveyor belts and standard components. The loaded and empty portion of the belt passes through the ‘carry and return runs’ of the horizontal curve in unconstrained equilibrium by super-elevating the idlers. Horizontal curves may also be combined with convex and/or concave vertical curves

FreeChatFor pipe conveyors it is desirable to separate the Kx term into separate values for trough and return belt because the value for return Kx is much larger than for standard conveyors. To develop the Ai factors for pipe conveyors, we first reduce Ai by 6/7 to delete one of the return idler bearings (assumes returns at twice trough idler spacing). The value

FreeChatA plane curve is called convex if it lies on one side of each of its tangent lines. In other words, a convex curve is a curve that has a supporting line through each of its points. Definition by convex sets. A convex curve may be defined as the boundary of a convex set in the Euclidean plane. This definition is more restrictive than the definition in terms of tangent lines; in particular, with this definition, a convex curve
