Blade Core Passageways for Cooling Multi-Blade Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blade assemblies lack effective cooling mechanisms, as the flow openings on cutting, grinding, or grooving blades are not optimally aligned or configured to enhance coolant flow through the blades, leading to inefficient cooling.
Innovation Solution
The blade assembly features a plurality of blade cores with flow openings of varying geometries, cross-sectional areas, radial positions, and arcuate positions, which are aligned to form passageways that extend across multiple blade cores, allowing for improved coolant flow and distribution, with the passageways starting and ending at different radial positions and orientations relative to a common reference on the blade shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If flow openings are aligned to form passageways across multiple blade cores, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The blade assembly is divided into multiple discrete blade cores (first blade core, second blade core, third blade core) with individual flow openings in each. These segmented openings are positioned to collectively form continuous passageways across the assembly, allowing coolant to flow through multiple segments in sequence to achieve effective cooling of the cutting blades.
2Quantity of substance
If flow openings have varying geometries and positions, then coolant flow distribution is improved, but manufacturing precision requirements increase
Solution Approach 1:
Each blade core has flow openings with specific local characteristics - different geometries, cross-sectional areas, radial positions, and arcuate positions - optimized for their particular location in the assembly. For example, openings in inner portions of blade cores differ from those in outer portions, allowing tailored coolant flow distribution to match local cooling requirements of different blade regions.
Solution Approach 2:
The flow openings are deliberately configured with asymmetric variations in geometry and positioning across the blade cores. The passageways are formed at angles other than normal to the blade cores, and openings have different cross-sectional areas at different locations, creating non-uniform coolant flow paths that optimize cooling efficiency while breaking symmetry to achieve better flow distribution.
3Area of stationary object
If passageways extend across multiple blade cores, then cooling coverage is improved, but device complexity increases
Solution Approach 1:
Individual flow openings from multiple separate blade cores are merged to form continuous passageways that extend across the entire blade assembly. The openings in adjacent blade cores are positioned to align and connect, creating integrated cooling paths that span multiple components and collectively cover the full cutting blade assembly, thereby expanding cooling coverage through combination of parts.
Solution Approach 2:
The passageways are configured to extend in multiple spatial dimensions across the blade assembly - radially outward from the blade shaft, arcuately around the assembly, and axially through the blade cores. This multi-dimensional arrangement of openings and passageways maximizes cooling coverage throughout the three-dimensional volume of the blade assembly rather than relying on simple linear paths.
