Longitudinal Side Support Coupling for Weaving Machine Shafts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weaving technologies face limitations in operating at higher speeds over longer periods due to wear and deformation issues in clutch elements and web shafts, leading to reduced efficiency and increased maintenance costs.
Innovation Solution
A page support system with a side support that features a clutch element designed for longitudinal movement, allowing for a play-free coupling with the weaving machine. This design reduces shear forces caused by shaft rod deformations and enables operation without expensive, high-strength shaft rods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lateral movement coupling is used to enable quick release and height adjustment, then ease of operation is improved, but play in the direction of movement occurs causing increased wear and limiting operating speed
Solution Approach 1:
Instead of moving the coupling laterally to engage/disengage (conventional approach), the invention inverts the movement direction to longitudinal (vertical) motion. The coupling element moves in the longitudinal direction of the side support to couple with the machine-side coupling unit, eliminating lateral play while maintaining quick operation capability.
Solution Approach 2:
The coupling system is segmented into a side support with coupling element and a separate machine-side coupling unit. This segmentation allows the coupling element to be designed with longitudinal movement capability while the machine-side unit remains fixed, resolving the conflict between ease of operation and wear resistance.
2Productivity
If shaft rods are used on high-speed weaving machines, then productivity is improved, but high loads cause considerable deformation particularly near lateral ends
Solution Approach 1:
The invention extracts the coupling function from the shaft rod structure itself and places it in a separate coupling element on the side support. This allows the shaft rod to be simpler and less expensive while the coupling element absorbs the deformation through longitudinal movement, maintaining high-speed operation capability.
Solution Approach 2:
The coupling element is designed with dynamic longitudinal movement capability that allows it to accommodate shaft rod deformation. This dynamic adjustment prevents stress concentration on the shaft rod while maintaining operational stability at high speeds.
3Adaptability or versatility
If coupling elements are attached to side support for height adjustment, then adaptability is improved, but shear forces increase between frame bars and coupling elements
Solution Approach 1:
The invention inverts the coupling movement from lateral to longitudinal direction. This inversion changes the force distribution so that shear forces between frame bars and coupling elements are eliminated, as the longitudinal movement does not create lateral shear stress on the frame structure.

AI summary
The present invention describes a side support for a weaving shaft for a loom, a loom, and a method for coupling a side support to a loom. The side support is configured to move parallel to its longitudinal direction within the loom during weaving. The side support has its greatest extent in the longitudinal direction. Two connecting elements for each of a weaving shaft rods are arranged longitudinally spaced apart on the side support. The side support has a coupling element at one end in the longitudinal direction. The side support is characterized in that the coupling element is configured to be coupled to the loom by a linear relative movement in the longitudinal direction.
