Solution Overview

Problem

Conventional elastomeric bearings for agricultural equipment face challenges in assembly due to loose elastomer bodies, which can shift during operation, leading to potential failure and limited axial force transmission, and require significant effort.

Innovation Solution

The elastomeric bearing features a multi-part clamping housing with permanently or detachably connected elastomer elements to the housing parts, ensuring stable attachment and improved axial force transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If loose elastomer bodies are inserted between the support and housing parts, then the bearing can be assembled, but the elastomer bodies can shift during operation leading to deterioration or complete failure

Engineering Contradiction:
Improvebearing function reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The elastomer bodies are pre-attached to the inner surface of the housing parts before assembly, ensuring they are positioned correctly and cannot shift during operation. This preliminary attachment action eliminates the reliability issue while simplifying the overall assembly process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses a simplified elastomer bearing design where the elastomer bodies are integrally attached to the housing, creating a more robust and reliable connection that prevents shifting and deterioration during operation.

Inventive Principle:
Principle #26Copying

2Ease of operation

If multiple disc arms with elastomer bearings are assembled, then the functional arm is supported, but significant assembly effort is required

Engineering Contradiction:
Improveassembly easeVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The elastomer bodies are pre-attached to the housing parts in a controlled manufacturing setting, so that during field assembly, the bearing components can be quickly installed as pre-assembled units, significantly reducing assembly time and effort.

Inventive Principle:
Principle #10Preliminary action

3Force

If conventional elastomer bearings are used, then the functional arm is elastically connected to the support, but only relatively low axial forces can be transmitted

Engineering Contradiction:
Improveaxial force transmissionVSAvoidbearing function stability
Core Design Contradiction:

Solution Approach 1:

The elastomer bodies are pre-attached to the housing parts with proper positioning and orientation, ensuring optimal load distribution and maximizing the axial force transmission capability while maintaining bearing stability during operation.

Inventive Principle:
Principle #10Preliminary action
