Counterweight Vibration Cancellation in Working Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing working machines experience significant shaking due to the swinging of their working members, which affects the stability and handling of the device, particularly when used for tasks like digging up ground soil.
Innovation Solution
Incorporating a counterweight mechanism inside the housing that swings in synchronization with the working member, canceling out the shaking by reciprocating movements, thereby reducing the overall vibration of the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a working member is swingably supported outside the housing to perform working operations, then the working capability is improved, but the housing experiences significant shaking that reduces stability
Solution Approach 1:
A counterweight is disposed inside the housing and configured to swing as the working member swings. The counterweight and working member are configured to swing toward each other and swing away from each other, creating opposite shaking forces that cancel each other out, thereby reducing the net shaking of the housing while maintaining working capability.
2Productivity
If the working member swings to perform digging operations, then the productivity is improved, but the shaking increases making handling difficult
Solution Approach 1:
The counterweight inside the housing swings in opposition to the working member, generating counterbalancing forces that reduce the shaking transmitted to the housing. This allows the working member to maintain its digging capability while the housing remains more stable and easier to handle during operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively minimizes the shaking of the housing, enhancing the stability and ease of handling the working machine, especially during operations like digging, by counteracting the vibrations caused by the working member's swing with those of the counterweight.
Implementation Method 1
the shaking of the housing caused by the swinging of the working member can be cancelled by the shaking of the housing caused by swinging of the counterweight
Data Source
AI summary
A working machine disclosed herein may include: a housing; a working member swingably supported by the housing and at least partially disposed outside the housing; and a counterweight disposed inside the housing and configured to swing as the working member swings. The working member and the counterweight may be configured to swing toward each other and swing away from each other.
