Compressor Gear Counterweight Locking With Spherical Balance Weights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressed air supply systems require inflexible and complex balancing weights that need to be specifically manufactured for each application, leading to increased costs and potential installation errors.
Innovation Solution
The use of spherical ball bearing balls as balancing weights, which are easily locked into position within trapezoidal recesses on the gear, allowing for a simple and flexible connection without welding, and enabling uniform counterweight distribution with multiple weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional balancing weights are used with welding or heat deformation, then the balancing weight is securely fixed, but the manufacturing complexity increases and flexibility is reduced
Solution Approach 1:
The balancing weight is designed as a spherical element that fits into a corresponding recess in the gear. The spherical shape allows for simple detent connection without requiring welding or heat deformation processes, thereby reducing manufacturing complexity while maintaining secure fixation through the geometric interlock between the sphere and recess.
Solution Approach 2:
The balancing weight is separated as an independent spherical element that can be individually selected and installed in different gear configurations. This segmentation allows for flexible combination of multiple balancing weights to achieve desired balance effects without requiring complex integrated designs or additional securing processes.
2Manufacturing precision
If multiple different balancing weights are manufactured specifically for each application, then the balancing precision is improved, but the manufacturing cost and stock requirements increase
Solution Approach 1:
A single universal spherical balancing weight design is created that can be used across multiple different applications and gear types. The spherical shape and standardized recess fit allow the same balancing weight to be applied in various configurations, eliminating the need to manufacture and stock multiple different balancing weight types while still achieving the required balancing precision through selective placement and combination of weights.
Solution Approach 2:
Instead of creating different balancing weight shapes or sizes for each application, the system uses parameter changes in the arrangement, number, and positioning of identical spherical balancing weights to achieve different balancing effects. This allows precise balancing control while maintaining a single standardized weight design for manufacturing and inventory purposes.
3Adaptability or versatility
If spherical balancing weights are used, then the installation flexibility is improved and incorrect installations are avoided, but the securing mechanism must be simple
Solution Approach 1:
The spherical balancing weight fits into a corresponding spherical or cup-shaped recess in the gear, creating a simple detent connection. The curved surfaces of the sphere and recess provide stable geometric interlock that prevents incorrect installation orientations while maintaining a simple securing mechanism without additional fasteners or complex assembly procedures.
