Modular Grinding Disc Receptacle for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding disc receptacles fail to adequately attenuate vibrations during high-performance grinding, leading to suboptimal machining results and potential tool damage due to unbalanced masses.
Innovation Solution
A modular grinding disc receptacle design featuring a hollow-cylindrical main body with a through-pipe that acts as a coolant pipe, providing joint damping and increased stiffness, along with adjustable bracing and damping elements such as annular discs and elastomers to mitigate vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single integrally configured receptacle main body with one damping element is used, then the structure is simple, but the damping effect is insufficient to attenuate vibrations during high-performance grinding
Solution Approach 1:
The receptacle main body is divided into multiple separate components (first receptacle component, second receptacle component, third receptacle component) that are joined together. These joints create multiple damping interfaces that collectively provide sufficient vibration attenuation during high-performance grinding operations.
2Strength
If the receptacle main body is made solid to increase stiffness, then structural rigidity improves, but weight increases
Solution Approach 1:
The receptacle main body is designed as a hollow-cylindrical structure with optimized wall thickness, providing the necessary stiffness through its cylindrical geometry and material distribution while minimizing weight by removing unnecessary material from the interior.
3Reliability
If multiple damping elements and modular components are added to enhance damping, then vibration attenuation improves, but device complexity increases
Solution Approach 1:
The receptacle is divided into modular components that are joined together to create damping interfaces. This segmentation provides effective vibration attenuation through the joints while keeping each individual component relatively simple in design.
Solution Approach 2:
The joints between receptacle components serve dual functions: they mechanically connect the structural elements to maintain stiffness and simultaneously act as damping elements to attenuate vibrations, eliminating the need for separate dedicated damping components.
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 design achieves a high degree of stiffness, reduced weight, and enhanced damping, effectively reducing vibrations and improving machining precision while preventing tool damage.
Implementation Method 1
Coolant can be directed—from the working spindle-proximal interface to the grinding disc bearing—by way of an inner duct in the otherwise integrally configured receptacle main body
Implementation Method 2
The grinding disc receptacle according to the invention, as a result of the provided construction thereof, unifies a plurality of advantageous effects. The modular construction of the receptacle, composed of a plurality of components that are able to be joined to one another, or are joined to one another, respectively, such as the receptacle main body and the through-pipe disposed in the cavity of the receptacle main body, and joints arising therefrom, thus has/have a damping effect
Implementation Method 3
The modular construction of the receptacle, composed of a plurality of components that are able to be joined to one another, or are joined to one another, respectively, such as the receptacle main body and the through-pipe disposed in the cavity of the receptacle main body, and joints arising therefrom, thus has/have a damping effect

AI summary
The grinding disc receptacle has a rotationally symmetrical, hollow-cylindrical receptacle main body. A through-pipe, which is braced in particular in relation to the receptacle main body, is disposed in the cavity of the receptacle main body so as to be spaced apart from the cylinder barrel of the hollow-cylindrical receptacle main body.
