Self-Sealing Tire Coating Frame for High-Speed Jump Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of truck-bus radial self-sealing tires faces challenges with incomplete cleaning and uneven spraying due to the tire jumping during high-speed rotation, leading to poor dynamic balance performance and safety issues.
Innovation Solution
A device comprising a support frame, positioning frame, and positioning roller system that stabilizes the tire by rotating around a central axis, ensuring the positioning roller abuts the tire tread to prevent jumping and ensure even coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the supporting machine drives the tire to rotate at high speed, then the coating process efficiency is improved, but the tire experiences severe jumping causing incomplete cleaning and uneven spraying
Solution Approach 1:
The positioning frame is designed with counterbalancing weights that offset the centrifugal force generated during high-speed rotation. These weights are strategically positioned to create opposing forces that prevent the tire from jumping, allowing high-speed operation while maintaining coating uniformity and preventing incomplete cleaning or uneven spraying
2Weight of moving object
If the tire size and weight are increased for truck-bus applications, then the load-bearing capacity is improved, but the coating process becomes more difficult and complex
Solution Approach 1:
The positioning frame incorporates adjustable positioning rollers and movable support structures that can dynamically adapt to different tire sizes and weights. The system allows real-time adjustment of support points and positioning mechanisms, enabling the same coating device to handle various tire specifications without requiring complete redesign or increasing process complexity
Solution Approach 2:
The positioning frame is designed as a universal system that can accommodate different tire types and sizes through adjustable components. The same positioning mechanism serves multiple functions: supporting heavy tires, maintaining proper positioning during rotation, and adapting to various tire dimensions, thereby simplifying the overall coating process for truck-bus applications
