Conveying Roller Head Element Frictional Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor rollers lack reliability and precision in conveying materials, particularly in starting and stopping, due to inadequate transmission of rotation between rollers.
Innovation Solution
A conveyor roller design featuring a holding element with a radial distance greater than the roller axis, which is inserted into the hollow end of the roller body, creating a secure frictional connection and preventing relative rotational movement, enhancing the transmission of torque and precision in material conveying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a head element is inserted into the hollow end of the roller body without a holding element, then the manufacturing process is simple, but the reliability and precision of rotation transmission deteriorates
Solution Approach 1:
The head element is divided into two functional parts: the insertion section that fits into the roller body and the holding element that provides rotational constraint. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The holding element acts as an intermediary component between the insertion section and the roller body, creating a secure frictional connection that prevents relative rotational movement without requiring complex mechanical fastening systems.
2Manufacturing precision
If a holding element with radial distance greater than roller axis is used, then the precision of conveying material is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The holding element extends in the radial direction beyond the roller axis, utilizing the radial dimension to create a frictional connection that prevents relative rotation. This dimensional approach simplifies the assembly process while achieving precise conveying control.
3Strength
If the head element is rigidly connected to the roller body, then the strength of connection is improved, but the ability to transmit rotation to other rollers deteriorates
Solution Approach 1:
The connection type is changed from rigid to frictional, which allows the head element to maintain strong connection to the roller body while enabling reliable rotation transmission to other rollers through the frictional interface created by the holding element.

AI summary
The invention relates to a conveyor roller for conveyor systems for the purpose of conveying containers, pallets and the like, comprising a roller body with a roller axis, the outer peripheral area of which represents a bearing surface for material to be conveyed, and a head element that is inserted with an insertion section into a hollow end of the roller body. The invention further relates to a method for manufacturing such a conveyor roller. In the case of the conveyor roller according to the invention, a holding element is arranged at the insertion section, which holding element has at least one point on the outer circumference thereof, the distance of which in a radial direction from the roller axis is greater than a distance between the roller axis and a point on an inner circumference of the hollow end of the roller body in the same radial direction.
