Convex-Tooth Conveyor Belt for Stable Torque in Concave Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller conveyors with round grooves suffer from poor torque transmission and increased wear due to uneven contact surfaces, leading to potential belt disengagement and reduced service life, particularly in curved sections.
Innovation Solution
A transmission belt with an elastomer-based body featuring a convex toothing and embedded tension cords, combined with a controlled coefficient of friction coating, is designed to fit concave grooves, enhancing torque transmission and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional round belts are used in round grooves, then the belt is easy to fit and inexpensive, but the contact surface is uneven leading to poor torque transmission and increased wear
Solution Approach 1:
The belt is designed with a specific convex cross-sectional shape that matches the concave groove geometry, creating a localized optimal contact surface at the belt-groove interface. This local geometric adaptation ensures uniform pressure distribution and maximizes torque transmission while maintaining ease of installation.
2Reliability
If the belt is made wider to improve torque transmission, then the contact surface increases, but the belt becomes more prone to turning over in curved sections
Solution Approach 1:
The belt cross-section incorporates specific curved surfaces with optimized radius of curvature that match the groove geometry. This curvature design ensures the belt maintains its position in the groove while distributing contact forces evenly, preventing both disengagement and overturning in curved conveyor sections.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The belt achieves improved torque transmission and reduced risk of overturning, extending service life and reducing infrastructure and energy costs by allowing more slave rollers per driving roller.
Implementation Method 1
a coating arranged on an outer surface of the toothing defining, with a shape of the outer surface of the toothing, a coefficient of friction with a groove of a roller that is non-zero and less than or equal to 0.8

AI summary
A transmission belt for a roller conveyor having rollers having concave grooves and made of steel or plastic is disclosed. The belt comprises an elastomer-based body comprising a dorsal portion and a ventral portion formed by a single toothing, an outer surface of which has a convex shape configured to engage with a concave groove of a roller; a set of tension cords embedded in the body between the dorsal portion and the ventral portion of the body; and a coating arranged on the outer surface of the toothing and defining, with the convex shape of the outer surface of the toothing, a coefficient of friction with the concave groove of a roller that is non-zero and less than or equal to 0.8.
