Dynamic Balancing Beads in Rotating Member Vessel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotating members in devices such as drive shafts and pump shafts become imbalanced over time due to wear and foreign objects, requiring a system that can dynamically compensate for changes in mass and realign the center of mass with the axis of rotation.
Innovation Solution
A balancing system comprising a vessel with solid balancing beads inserted into a hollow portion of the rotating member, where the beads are centrifugally positioned to offset imbalances and vibrations, using a shell that conforms to the inner walls of the hollow portion for a friction fit, allowing the system to dynamically adjust for changes in the rotating member's mass distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional static balancing methods are used, then initial balance is achieved, but the rotating member becomes imbalanced over time due to wear and foreign objects
Solution Approach 1:
The patent employs dynamic balancing beads that can move freely within a balancing chamber instead of fixed static weights. These beads automatically redistribute themselves under centrifugal force during rotation, allowing the balancing system to adapt continuously to changing mass distributions caused by wear and foreign objects, thereby maintaining balance effectiveness throughout the operational duration
Solution Approach 2:
The balancing system performs self-adjustment through the automatic movement and redistribution of balancing beads under centrifugal force. The system requires no external intervention or control mechanisms to maintain balance - the beads naturally migrate to positions that counteract imbalance forces, enabling the rotating member to self-correct its balance state continuously during operation
2Manufacturing precision
If the center of mass is fixed, then initial alignment with axis of rotation is achieved, but the system cannot compensate for changes in mass distribution over time
Solution Approach 1:
The system transitions from a fixed center of mass to a dynamic center of mass that can shift position automatically. The balancing beads move within the chamber to reposition the effective center of mass in real-time, enabling the system to adapt to changing mass distributions while maintaining alignment with the axis of rotation throughout operation
3Productivity
If wear and foreign objects cause imbalance, then operational continuity is maintained, but vibrations and torque issues increase over time
Solution Approach 1:
The balancing system continuously self-adjusts by allowing balancing beads to migrate under centrifugal force, automatically counteracting vibrations and torque imbalance generated by wear and foreign objects. This self-correcting mechanism enables prolonged operational continuity without the accumulation of harmful vibrational effects
Solution Approach 2:
The system provides continuous feedback through the movement of balancing beads in response to imbalance forces. The beads naturally migrate toward positions that counteract vibrations and torque issues, creating a self-regulating feedback loop that suppresses harmful factors while maintaining operational continuity
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
The system effectively maintains balance by redistributing the mass of the balancing beads under centrifugal force, reducing vibrations and compensating for wear and foreign objects, thus ensuring continuous operation without undesirable torque or imbalance issues.
Implementation Method 1
the balancing beads are centrifugally positioned within the vessel to compensate for imbalance in the rotating member

AI summary
A balancing system for a rotating member is presented. The rotating member includes a hollow portion and an axis of rotation which extends through the hollow portion. The balancing system includes a vessel that is insertable into the hollow portion of the rotating member. The vessel includes an outer shell which is shaped to conform to inner walls of the hollow portion. A plurality of solid balancing beads partially fill the vessel. When the vessel is inserted into hollow portion and the rotating member is rotating, the axis of rotation passes through the vessel and the balancing beads are centrifugally positioned within the vessel to compensate for imbalance in the rotating member.
