Solution Overview
Problem
Existing clamping elements for connecting a motor shaft to a transmission via a hub often slip and are difficult to fix securely, lacking effective radial and axial securing mechanisms.
Innovation Solution
A clamping element with an elastically deformable region and a fixing element that tapers inward to secure the motor shaft against rotation and slipping, featuring a recess and/or hole for mass balance, allowing secure radial and axial fixation with reduced necessary forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional clamping ring is used to connect motor shaft to transmission hub, then the connection can be established, but the clamping ring frequently slips and cannot be easily fixed securely
Solution Approach 1:
The clamping element is segmented into a basic body with a gap and elastically deformable regions, allowing localized deformation at the gap while maintaining overall structural integrity. This segmentation enables the fixing element to apply force selectively at the gap region to create friction grip without requiring uniform compression around the entire circumference.
Solution Approach 2:
The invention changes the physical state of the clamping element by introducing elastically deformable regions that can dynamically adjust their shape. When the fixing element is inserted, it causes radial inward deformation at the gap, changing the inner diameter parameter locally to create secure friction-based fixation against the hub.
2Reliability
If high fixing forces are applied to prevent slipping, then securing reliability improves, but the complexity of the fixing mechanism increases
Solution Approach 1:
The clamping element performs self-service by using the fixing element to induce elastic deformation at the gap, which automatically generates the necessary friction force to prevent slipping. The elastically deformable region acts as a self-regulating mechanism that creates adequate fixation force without requiring complex external actuation or multiple fixing components.
Solution Approach 2:
The invention employs flexible, elastically deformable regions within the rigid clamping element structure. These flexible zones allow the basic body to deform radially inward at the gap when subjected to the fixing element, creating friction-based securing without requiring high overall fixing forces or complex mechanisms.
3Strength
If the clamping element is made from solid material without deformable regions, then structural strength is maintained, but the ease of pushing together and fixing increases
Solution Approach 1:
The clamping element features local quality variation by incorporating elastically deformable regions specifically at the gap area while maintaining solid, strong material in the rest of the structure. This localized deformability allows easy pushing together and fixing at the gap region without compromising the overall structural strength needed for torque transmission.

AI summary
In the case of a clamping element for connecting a motor shaft to a transmission via a hub (3), in particular transmission component, such as transmission drive shaft, sun wheel, clutch or the like, with at least one fixing element (7) being inserted radially in the clamping element, the fixing element (7) is at the same time to form both a tangential element for securing the clamping element (R1, R2) against rotation and an axial element for securing the clamping element (R1, R2) with respect to the hub (3).
