Threaded Ring Axial Fixing Wire Race Bearing Drive
Solution Overview
Problem
Existing drive systems with wire race bearings require multiple parts and discrete adjustments, making them complex and costly to produce and assemble.
Innovation Solution
A drive system where a threaded ring is used to axially fix the wire race bearing, allowing for infinitely variable adjustment without the need for multiple parts, and can be screwed onto either the toothed part or housing, simplifying production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple individual parts are used for the toothed part or flange to permit discrete adjustment of the wire race bearing, then adjustment capability is provided, but device complexity and production cost increase
Solution Approach 1:
The patent merges multiple individual parts into a single integrated toothed part that includes an integrated flange. This single part contains both the toothed wheel and the flange with adjustment features, eliminating the need for separate parts and reducing assembly complexity while maintaining adjustment capability through integrated design features
Solution Approach 2:
The integrated flange serves multiple functions: it provides mounting holes for securing the wire race bearing, includes an adjustment feature (such as a threaded hole or slot) for adjusting the bearing's axial position, and maintains structural support. This multi-functional design eliminates the need for separate adjustment components while providing both structural and adjustment capabilities
2Adaptability or versatility
If multiple individual parts are used for the toothed part or flange to permit discrete adjustment of the wire race bearing, then adjustment capability is provided, but production cost increases
Solution Approach 1:
The patent combines multiple parts into a single integrated component that can be manufactured in one piece using standard machining or molding processes. This reduces the number of manufacturing operations, eliminates the need for multiple part inventories, and simplifies quality control, thereby reducing production costs while maintaining adjustment functionality through integrated design features
3Adaptability or versatility
If a threaded ring is screwed onto the toothed part or housing, then infinitely variable adjustment of the wire race bearing is enabled, but assembly complexity may increase
Solution Approach 1:
The threaded ring acts as an intermediary component that provides continuous adjustment capability. By screwing the threaded ring onto either the toothed part or the housing, the axial position of the wire race bearing can be precisely adjusted to any position along the thread, enabling infinitely variable adjustment while maintaining a simple two-component assembly structure
