Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vibration isolation systems for agricultural machines primarily focus on vertical direction isolation, neglecting radial and angular vibrations, which leads to premature fatigue of isolating elements and inadequate ergonomic conditions for operators due to unaddressed vibratory loads in multiple directions.
Innovation Solution
A vibration isolation device featuring radially arranged rubber elements on two crowns opposing the roller, with adjustable inclination between the roller shaft and supporting structure, providing flexible fastening and isolation in all directions to mitigate vibratory loads and prevent isolator fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rubber element is used for vibration isolation, then the structure is simple, but the isolation effectiveness is insufficient in multiple directions
Solution Approach 1:
The vibration isolation system is segmented into multiple rubber elements (at least two) arranged radially around the roller shaft, with each element handling specific directional vibrations. This segmentation allows comprehensive multi-directional isolation while maintaining reasonable structural complexity.
Solution Approach 2:
The invention transitions from single-direction vertical isolation to multi-dimensional radial isolation by arranging rubber elements around the roller shaft at different angular positions, covering all spatial directions including radial, tangential, and vertical vibrations.
2Reliability
If rubber elements are arranged vertically for main direction isolation, then vertical vibration isolation is improved, but radial and angular vibrations are not adequately addressed
Solution Approach 1:
The rubber elements are designed with universal multi-directional isolation capability through radial arrangement around the roller shaft. Each element can accommodate vertical, radial, and angular vibrations simultaneously, making the system versatile for all vibration directions rather than specialized for one direction.
Solution Approach 2:
The isolation capability extends from single vertical dimension to three-dimensional radial coverage by positioning rubber elements at different angular positions around the shaft, enabling comprehensive vibration isolation in all spatial directions.
3Device complexity
If isolating elements are not designed for multi-directional loads, then the structure is simpler, but the isolating elements fail prematurely due to fatigue
Solution Approach 1:
The isolation system segments vibratory loads into different directional components handled by specifically positioned rubber elements. This segmentation ensures each element is optimized for its directional load, preventing premature fatigue failure and extending service life.
Solution Approach 2:
The invention changes the configurational parameters of the isolation system by arranging rubber elements radially at specific angular positions and inclinations, optimizing their load-bearing parameters for multi-directional vibrations and thereby extending their operational duration.
4Reliability
If vibration isolation is not comprehensive in all directions, then the mechanical components suffer fatigue damage, but adding more isolators increases complexity
Solution Approach 1:
The system segments the protection function across multiple radially arranged rubber elements, with each element contributing to overall component durability. This segmented approach achieves comprehensive protection without requiring an overly complex centralized isolation mechanism.
Solution Approach 2:
The invention achieves comprehensive multi-directional protection by transitioning from single-point vertical isolation to distributed radial isolation around the shaft, covering all spatial dimensions and protecting mechanical components from fatigue in any direction.

AI summary
The invention relates to a vibration isolation device for agricultural machines comprising at least one roller coupled to the machine by means of a supporting structure to which the roller is secured at the ends thereof. The device can be used as a means for isolating the vibration produced as the roller is pulled along the ground. The device comprises multiple rubber isolating elements secured at each of the ends of the roller with variable inclination, said elements being distributed radially about the shaft such as to form a flexible link between the roller and the supporting structure.
