Clamping Device Centrifugal Counterweights High Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clamping devices fail to maintain reliable clamping at high revolution speeds due to centrifugal forces causing the device to open, leading to unreliable fixation of components.
Innovation Solution
Incorporation of centrifugal force counterweights in the cavities of the clamping device, which are designed to be pushed outwards by centrifugal forces, causing the receptacle to close and enhancing the clamping force, allowing reliable clamping even at speeds up to 250,000 revolutions/min.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If radial compressive forces are applied to deform the base element for clamping, then the receptacle opens to allow component insertion, but at high revolution speeds the centrifugal forces cause the clamping device to open and lose reliable clamping
Solution Approach 1:
Centrifugal force counterweights are provided in the cavities to counteract the harmful centrifugal forces. When the clamping device rotates, the counterweights are pushed outwards by centrifugal forces, causing the regions between them to bend inwards and close the receptacle, thereby maintaining clamping force even at high revolution speeds of up to 250,000 revolutions/min
Solution Approach 2:
The harmful centrifugal forces that tend to open the clamping device at high speeds are converted into a beneficial effect. The counterweights utilize these centrifugal forces to generate an inwards bending moment on the base element, which actively closes and secures the receptacle, transforming the destabilizing force into a clamping mechanism
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 solution ensures reliable clamping and strengthens the clamping force at high rotation speeds by utilizing centrifugal force counterweights that deform the base element to maintain a secure press fit, effectively addressing the issue of clamping device instability at high speeds.
Implementation Method 1
If the clamping device according to the invention is set in rotation, the centrifugal force counterweights are pushed outwards due to the centrifugal forces that occur with the result that the regions lying between them are bent inwards, and so the receptacle closes
Implementation Method 2
the base element being elastically deformable by radial compressive forces which are applied from the outside in the region of the cavities such that a component to be clamped can be pushed into the receptacle, and by reducing or releasing the radial compressive forces can be elastically deformed back in order to create a pressure connection with the component to be clamped

AI summary
The invention relates to a clamping device which comprises a base, having a center holding fixture for a structural component to be clamped and a plurality of cavities arranged around the holding fixture. The base can be elastically deformed in such a manner by radial compressive forces applied from the outside in the area of the cavities that a structural component to be clamped can be inserted in the holding fixture and can be elastically returned to its former shape by reducing or releasing the radial forces, thereby establishing a pressure connection with the structural component to be clamped. The invention is characterized in that centrifugal counterweights are provided inside the cavities.
