Tiltable Edge Regulating Member for Belt Rotation Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing belt rotation devices require complex configurations, including an additional inclined roller shaft, to minimize sliding friction between the edge regulating member and the belt, which can lead to belt damage during misalignment.
Innovation Solution
A simple configuration featuring an edge regulating member with a body that contacts the inner surface of the belt and a regulating portion extending radially outward, which tilts due to belt tension to reduce sliding friction when the belt is misaligned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an inclined flange roller is added to reduce sliding friction, then belt damage is prevented, but device complexity increases
Solution Approach 1:
The patent merges the edge regulating function and the sliding friction reduction function into a single integrated structure. The regulating portion is formed as an integral part of the edge regulating member body, eliminating the need for separate inclined flange rollers and complex mounting mechanisms. This integration maintains the belt protection function while significantly simplifying the overall device configuration.
Solution Approach 2:
The regulating portion is designed to be tiltable relative to the body, allowing it to dynamically adjust its angle in response to belt tension. When the belt becomes misaligned and contacts the regulating portion, the portion tilts to reduce sliding friction, automatically adapting to the belt's movement without requiring external control mechanisms or complex mechanical linkages.
2Object-affected harmful factors
If a complex inclined roller shaft system is used, then sliding friction is reduced, but manufacturing complexity increases
Solution Approach 1:
The edge regulating member is segmented into two functional parts: a stationary body and a tiltable regulating portion. This segmentation allows the regulating portion to independently adjust its angle to reduce sliding friction, while the body provides stable support. The segmented design simplifies manufacturing compared to complex inclined roller shaft systems, as each part can be manufactured separately and assembled through simple mounting.
Solution Approach 2:
The regulating portion automatically tilts in response to belt tension and contact forces, requiring no external actuation or complex mechanical linkages. This self-adjusting mechanism eliminates the need for complicated inclined roller shaft systems, making the device easier to manufacture while maintaining the ability to reduce sliding friction effectively.
3Device complexity
If the regulating portion is fixed, then structural simplicity is maintained, but sliding friction increases causing belt damage
Solution Approach 1:
The regulating portion is designed with tiltable capability, allowing it to dynamically adjust its angle relative to the body in response to belt contact forces. This dynamic adjustment reduces sliding friction between the regulating portion and the belt edge, preventing belt damage while maintaining configuration simplicity through a single integrated structure without complex external mechanisms.
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
This solution effectively minimizes sliding friction and prevents belt damage by allowing the belt to make point contact with the regulating portion, reducing the load on the belt edge during misalignment.
Implementation Method 1
tension of the belt acting on the body while the inner surface of the belt is in contact with the body causes the regulating portion to tilt
Implementation Method 2
sliding friction between the regulating portion and the edge of the belt is maximally reduced

AI summary
An edge regulating member provided in a belt rotation device that tensions a belt via a belt tensioning roller and rotates the belt in a rotation direction includes a body that comes into contact with an inner surface of the belt and a regulating portion that extends, at a position adjacent to the body, further outward in a radial direction of the belt tensioning roller than the body, and comes into contact with an edge of the belt. Tension of the belt acting on the body while the inner surface of the belt is in contact with the body causes the regulating portion to tilt, turned outward in the rotation axis direction from a fold-back portion of the belt toward an upstream side in the rotation direction.
