Grinding Tool Support Body With One-Sided Recess Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier bodies for grinding or cutting tools with recesses designed as bushings face issues of high complexity in production, noise, and imbalance due to turbulence when using a cooling medium, and are not suitable for effective cooling.
Innovation Solution
An asymmetrical design with recesses open on one side, covered by a common annular cover, and optionally filled with a filler, to reduce noise and maintain radial elasticity, allowing for efficient cooling without turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If recesses are designed as bushings to reduce weight, then weight is reduced, but noise increases and cooling medium causes turbulence and imbalance
Solution Approach 1:
The recesses are designed to be open only towards one side surface of the carrier body, creating an asymmetrical configuration. This asymmetry allows the cooling medium to flow through the recesses in a controlled manner, preventing turbulence and noise generation while maintaining the weight reduction benefit of the recessed structure
Solution Approach 2:
The recesses are selectively opened only on one side surface while remaining closed on the opposite side. This local differentiation in openness allows the carrier body to maintain radial elasticity where needed while providing controlled cooling medium flow paths, thereby reducing noise and preventing imbalance
2Object-generated harmful factors
If cover elements are applied to close bushings, then noise is reduced, but production complexity increases significantly
Solution Approach 1:
Instead of applying cover elements to close recesses from both sides, the design asymmetrically opens the recesses only on one side surface. This eliminates the need for multiple cover elements and complex multi-step assembly processes, significantly simplifying production while still achieving noise reduction
3Object-generated harmful factors
If recesses are completely closed, then radial elasticity is lost, but noise is reduced
Solution Approach 1:
The recesses are designed with differentiated openness - open on one side surface to maintain radial elasticity and closed on the opposite side to reduce noise. This local quality differentiation allows the carrier body to simultaneously achieve both radial elasticity and noise reduction without compromising either property
