Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing funding systems for promoting bulk goods suffer from significant wear of the deflection wheel, leading to impaired deflection and frequent replacements, which result in considerable effort and downtime.
Innovation Solution
The deflection wheel is designed with a metallic first deflection section and a second deflection section made of plastic, specifically polyurethane, which provides enhanced abrasion resistance and reduces wear, while maintaining stability through the metallic section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the deflection wheel contact surface is made of metal, then the structural stability and strength are maintained, but significant wear occurs during operation leading to frequent replacements
Solution Approach 1:
The deflection wheel combines a metallic core structure with a polyurethane coating layer. The metallic core (steel or stainless steel) provides structural stability and strength, while the polyurethane coating layer provides high wear resistance and extends the service life of the deflection wheel by forming a protective contact surface that resists abrasion from the carrier device.
Solution Approach 2:
The deflection wheel has different material properties in different regions: the core structure is made of metal for overall stability, while only the contact surface region is covered with polyurethane material. This localized application of different materials optimizes both structural integrity and wear resistance where needed most.
2Stability of the object's composition
If the deflection wheel is made entirely of metal, then the stability is maintained, but the wear leads to impaired shape and frequent replacement requiring considerable downtime
Solution Approach 1:
The deflection wheel combines a metallic core structure with a polyurethane coating layer. The metallic core (steel or stainless steel) provides structural stability and strength, while the polyurethane coating layer provides high wear resistance and extends the service life of the deflection wheel by forming a protective contact surface that resists abrasion from the carrier device.
Solution Approach 2:
The invention changes the material parameter of the contact surface from metal to polyurethane, which has superior wear resistance properties. This material parameter change extends the operational life of the deflection wheel significantly, reducing the frequency of replacements and minimizing downtime for the conveyor system.
3Reliability
If a plastic coating is applied on the metallic section, then the abrasion resistance is enhanced, but the manufacturing complexity increases

AI summary
The invention relates to a conveying system for transporting bulk material. The conveying system comprises a drive device designed to rotate in a circular direction, which has at least one flexible traction element and several drive elements arranged on the traction element and extending transversely away from the traction element in the circular direction. The conveying system also includes a deflection wheel rotatably mounted about a deflection axis for redirecting the drive device. The deflection wheel comprises a metallic first deflection wheel section and bears against the drive device with a contact surface facing away from the deflection axis. According to the invention, the contact surface is at least partially formed by a second deflection wheel section of the deflection wheel made of plastic.
