Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine tools with linear guideways and ball screws experience significant wear and noise due to resonance and vibration during high-speed movements, leading to reduced service life and precision.
Innovation Solution
Incorporating a lightweight, shock absorption, and sound absorption material such as foam metal, polystyrene, asbestos, foam, plastic, or rubber within the hollow interior of the rail and block to reduce vibrations and noise, while using pipe materials for the rail and block to minimize weight and material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional solid rail and block structures are used, then structural strength and stability are maintained, but weight is excessive and vibrations cause noise and wear
Solution Approach 1:
The rail and block are divided into hollow sections with internal cavities, separating the external load-bearing structure from the internal filling material. This segmentation allows the outer shell to maintain structural strength while the hollow interior reduces weight and accommodates vibration-damping materials.
Solution Approach 2:
The invention uses composite construction by filling the hollow interior of the rail and block with vibration-damping materials (such as foam, rubber, or other viscoelastic materials) while maintaining the metallic outer shell. This composite structure combines the strength of metal with the vibration-absorbing properties of the filling material, resolving the contradiction between strength and weight.
2Productivity
If high speed movement is achieved, then productivity is improved, but vibrations and noises increase causing wear and reduced service life
Solution Approach 1:
The invention converts the harmful vibrations generated during high-speed movement into a beneficial effect by using the vibration-damping filling material to absorb and dissipate the vibrational energy. The hollow interior structure allows the filling material to effectively counteract vibrations, transforming the harmful resonance into reduced wear and extended service life.
Solution Approach 2:
The invention changes the physical parameters of the rail and block by introducing hollow sections filled with viscoelastic materials, which alter the vibrational characteristics and damping properties of the system. This parameter change allows high-speed operation while reducing the transmission of vibrations that would otherwise cause wear.
3Weight of moving object
If hollow structures with lightweight materials are used, then weight is reduced by 30-50%, but manufacturing complexity increases
Solution Approach 1:
The hollow sections are prepared in advance during the casting or extrusion process, creating pre-formed cavities that are ready to receive the vibration-damping filling material. This preliminary action simplifies the overall manufacturing process by integrating the hollow structure creation into the primary forming operation rather than requiring subsequent complex machining or assembly steps.
