Oval Spring Ring Connecting Arrangement for Constant Velocity Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting arrangements between a shaft end and a constant velocity joint are complex, costly, and material-intensive due to the production of components with ovalities, which complicates assembly and increases material loss.
Innovation Solution
A joint connection using a ring with oval regions, such as a spring ring, mounted in a groove of one of the components, allowing for easy assembly and economical production by forming a non-destructively releasable connection through axial alignment and force transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components with molded-on oval collars are used to create a non-destructive connection, then the connection reliability is improved, but the manufacturing complexity and material loss increase
Solution Approach 1:
The oval collar function is segmented from the main component and implemented as a separate ring element mounted in a groove. This ring can be a spring ring or other removable element, separating the ovality feature from the primary component manufacturing process, thereby reducing manufacturing complexity while maintaining connection reliability.
Solution Approach 2:
A ring element acts as an intermediary component that provides the oval collar function without requiring the main components (connecting nut or joint part) to be manufactured with complex oval features. The ring is mounted in a groove and provides the necessary geometric constraint for non-destructive release.
2Reliability
If components with molded-on oval collars are used to create a non-destructive connection, then the connection reliability is improved, but the material loss increases
Solution Approach 1:
The oval collar functionality is segmented into a separate ring component rather than being integrated into the main components. This allows the ring to be a simpler, more material-efficient element that can be mounted in a groove, reducing overall material consumption while maintaining the reliable non-destructive connection feature.
3Ease of manufacture
If a ring with oval regions is used instead of molded-on oval collars, then the ease of manufacture is improved, but the assembly complexity may increase
Solution Approach 1:
The ring with oval regions is pre-mounted in a groove of one of the components before final assembly. This preliminary action simplifies the overall assembly process, as the oval feature is already in place to guide the engagement of the connecting nut and joint part, preventing assembly complexity from increasing despite the manufacturing simplification.
4Ease of operation
If a spring ring with oval regions is used, then the ease of assembly is improved, but the production complexity may increase
Solution Approach 1:
The spring ring can be produced using standard spring manufacturing processes with controlled geometric parameters, including the oval region dimensions. By standardizing the ring production and mounting it in a simple groove, the ease of assembly is improved while production complexity remains manageable through parameter control rather than complex geometry.
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 enables an easily assembled, reliable, and cost-effective joint connection that facilitates the assembly of a constant velocity joint, reducing material waste and production complexity while maintaining operational reliability.
Implementation Method 1
The ring provided with an ovality can be a spring ring and the connecting nut can suitably be a locking nut. The collar having the ovality can therefore be a spring ring with its oval regions fixed radially, and in particular, facing outwardly, in a groove of the shaft end, the joint inner part or the clamping nut

AI summary
The invention relates to a connecting arrangement between a shaft end and a joint part in which a collar on a connecting nut engages behind a another collar on the shaft end or on the joint part or on a clamping nut which clamps a bearing on the shaft, and one of the collars is formed by a oval ring received in a groove which facilitates disassembly of the connection formed by the connecting arrangement.
