Conveyor Roller Axle Clamping via Elastic Damping Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller assemblies for conveyor systems have numerous individual parts, leading to mechanical weak points and wear surfaces, which can compromise their durability and performance.
Innovation Solution
A roller arrangement where the roller axle body is clamped in the insertion channels of the roller suspension using elastic damping elements, eliminating the need for additional clips and allowing the damping elements to serve both damping and attachment functions, with positive-locking connections for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual parts are used in the roller assembly (roller, roller suspension, damping element, clip), then the damping function can be achieved, but the number of mechanical weak points and wear surfaces increases
Solution Approach 1:
The patent combines the attachment function (clip) and damping function (damping element) into a single integrated damping element that performs both functions simultaneously. The damping element is designed with a clamping structure that directly secures the roller axle body to the roller suspension while providing vibration damping, thereby reducing the total number of parts and eliminating the mechanical weak points associated with multiple separate components
Solution Approach 2:
The damping element is designed to serve multiple functions: it provides vibration damping, attaches the roller to the roller suspension, and secures the roller axle body in position. This multi-functional design eliminates the need for separate clips and reduces the number of wear surfaces, thereby improving reliability while reducing device complexity
2Reliability
If multiple individual parts are used in the roller assembly, then the damping function can be achieved, but many wear surfaces are created
Solution Approach 1:
The patent merges the attachment and damping functions into a single component, thereby reducing the number of contact interfaces and wear surfaces. The integrated damping element has fewer mating surfaces compared to separate clips and damping elements, reducing the overall number of wear points in the assembly
3Device complexity
If elastic damping elements are used to clamp the roller axle body, then the number of parts is reduced, but the fastening mechanism becomes more complex
Solution Approach 1:
The damping element utilizes elastic deformation as a key parameter to achieve both attachment and damping functions. By designing the damping element with specific elastic properties and geometric features (such as curved surfaces and resilient sections), the component can dynamically adapt to assembly tolerances and provide secure fastening without requiring complex manufacturing processes or additional fastening mechanisms

Function Achieved in This Case
This design reduces the number of parts, enhances durability by eliminating mechanical weak points, and improves the roller assembly's performance by integrating damping and attachment functions into a single component.
Implementation Method 1
at least two elastic damping elements (7, 8) are interposed, by means of which the roller axle body (4) is clamped in a fastening position
Implementation Method 2
the elastic damping elements fulfill a dual function, namely the previously known damping of vibrations in the roller assembly
