- Description
- Skewed idler rolls are often used in belt conveyors to deliberately track belts. Applications include dynamic belt tracking systems, tilted wing rolls or deliberately misaligned idler frames. Additionally, skewed idler rolls may be introduced unintentionally as a result of poor manufacturing tolerances, structural misalignment, ground settlement, etc. Whether intentional, or otherwise, the influence of the skewed idler roll on the belt tracking performance is an area of interest for plant operators and designers, and while there have been a number of analytical investigations into the thrust force that a skewed idler roll imparts to a conveyor belt, there have been limited experimental investigations to prove the accuracy of these predictions. To examine the forces acting on a skewed idler roll this paper investigates the forces acting for static and dynamic loading scenarios. To achieve this, two test rigs located at the University of Newcastle have been developed. These testing rigs allow for measurements of the coefficient of friction and resulting dynamic forces to be quantitatively determined for a range of skew angles. A comparison of analytical investigations and experimentally measured results are shown where the prediction of the forces acting on a skewed idler roll in relation to belt mistracking can be undertaken.
