Weaving Machine Non-Stationary Driving Wheel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Weaving machines with movable drive elements and sley systems suffer from undesired vibrations due to the mass of the drive elements, leading to increased drive energy requirements and design complexity, which affects the precision and quality of fabric production.
Innovation Solution
Aligning the drive organ axis with the drive wheel axis and using an articulated connection with length and angular mobility to transmit rotary forces directly, reducing the mass of moving parts and intermediate components, allowing for more precise and efficient power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive element is arranged below the drive wheel and connected via intermediate components (such as crank drives, intermediate rods, or gear mechanisms), then the drive can be transmitted to the movable sley, but the mass of moving parts increases and additional vibrations are generated
Solution Approach 1:
The invention extracts and eliminates the intermediate transmission components (crank drives, intermediate rods, gear mechanisms) from the drive system. By directly coupling the drive element to the drive wheel, the patent removes the unnecessary intermediate elements that added mass and complexity, while maintaining reliable drive transmission to the movable sley.
Solution Approach 2:
Instead of arranging the drive element below the drive wheel with intermediate components, the invention inverts the arrangement by positioning the drive element directly on the drive wheel axis. This fundamental reconfiguration eliminates the need for complex intermediate transmission mechanisms and reduces the mass of moving parts.
2Stability of the object's composition
If the sley is reinforced and stiffened to counter undesired vibrations, then vibration resistance improves, but the mass of the sley increases and drive energy requirements increase
Solution Approach 1:
The invention converts the harmful vibrations caused by heavy drive elements into a beneficial situation by eliminating the source of vibrations through direct coupling. By removing intermediate components and reducing oscillating masses, the system naturally suppresses vibrations without requiring additional reinforcement, thereby reducing drive energy consumption.
3Adaptability or versatility
If intermediate components are used in the drive transmission, then the drive can accommodate relative movements, but the total play increases and precision decreases
Solution Approach 1:
The invention inverts the conventional approach by eliminating intermediate components that accumulate play. Instead of using multiple components to accommodate relative movements, the direct coupling of the drive element to the drive wheel minimizes total play while maintaining adaptability through the articulated connection that allows for relative movements.
