Conveyor rollers are one of the most massive and at the same time responsible elements of a belt conveyor. They take on the main load from the material and the conveyor belt. An error in determining the load or the wrong selection of the roller series leads to increased resistance to rotation (increased energy consumption), faster wear of bearing assemblies and, in some cases, even to a complete emergency stop of the production line.
Forces acting on conveyor rollers
The reliability of a conveyor line directly depends on the correct selection of rollers. If the equipment has too much safety margin, you have to invest significant funds that may not pay off. On the other hand, incorrectly calculated load or speed can lead to premature wear of bearings, shaft deformation and unplanned failure of conveyor rollers.
To simplify the selection process and ensure the smooth operation of your equipment, our ATS INDUSTRY team, in partnership with the world leader in the production of conveyor rollers and drums, Rulmeca Germany GmbH, calculates rollers using specialized software. As a result, you receive products that are guaranteed to meet your technical data without excessive costs.
The main risks of improper roller selection:
1. Bearing overload: reduces the service life of the roller several times.
2. Shaft bending: leads to jamming of the bearings and damage to the belt.
3. Uncalculated shock loads: destruction of the rollers in the material loading areas.
4. Incorrect selection of seals: penetration of dust or moisture into the bearing and its failure.
Key features of our software:
· Determination of the load on the roller support: the program calculates the static and dynamic forces acting on the central and lateral rollers.
· Bearing life check (L10h): estimates the service life of the bearings in hours depending on the operating conditions.
· Shaft strength and bending check: ensures that the roller shaft can withstand the specified loads.
· Selection of materials and seal types: helps to select rollers according to the environment of use (quarries, cement plants, port terminals, chemical industry).
