Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional rotor clamping devices are used, then they can clamp rotors, but the clamping forces are reduced due to high centrifugal forces at high speeds
Solution Approach 1:
The patent employs counterweights integrated into the clamping device that generate opposing centrifugal forces to compensate for the reduction in clamping force. These counterweights are positioned and dimensioned to create a balancing effect that maintains stable clamping force even at high rotational speeds, directly resolving the contradiction between maintaining clamping force and operating at high speeds.
2Reliability
If conventional rotor clamping devices are used, then they can clamp rotors, but they are expensive to manufacture and maintain
Solution Approach 1:
The clamping device is divided into modular components including the ring assembly, clamping elements, and counterweights that can be manufactured separately and assembled. This segmentation allows for simplified manufacturing processes, easier maintenance, and potential use of standard components, thereby reducing manufacturing costs while maintaining reliable clamping functionality.
3Reliability
If conventional rotor clamping devices are used, then they can clamp rotors, but they are cumbersome to unclamp
Solution Approach 1:
The clamping device utilizes dynamic elements that automatically adjust to rotational speed, where the counterweights and clamping elements move in response to centrifugal forces. This dynamic behavior provides secure automatic clamping at operating speeds while allowing easy release when rotation stops or slows, eliminating the need for complex manual unclamping mechanisms.
4Reliability
If conventional rotor clamping devices are used, then they can clamp rotors, but they cannot be adapted to different clamping tasks
Solution Approach 1:
The ring assembly with its modular clamping elements and adjustable counterweights is designed to accommodate various rotor types and clamping requirements. The system can be adapted to different clamping tasks by adjusting the position and configuration of components, making it a universal solution that maintains reliable performance across multiple applications.

AI summary
In a component for receiving and clamping a rotor, a ring assembly enclosing a hollow space includes rings lying one inside the other and with connectors extending radially through the ring assembly, by which the rings are connected to one another in a rotationally fixed manner. At least two clamping elements projecting into the hollow space are attached to the ring assembly, which form a receptacle for the rotor with clamping surfaces. There are also weights on the ring assembly for centrifugal force compensation.
