Dual-Gearing Angular Referencing Without Tooth Markings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing components with two gearings require additional unproductive manufacturing steps, such as generating and detecting markings, to identify reference teeth or gaps, which increases machining time and costs.
Innovation Solution
A method that identifies the reference tooth or gap of the first gearing by assigning measured actual angular distances to predetermined nominal angular distances, eliminating the need for separate markings and associated manufacturing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If markings are generated and detected to identify reference teeth or gaps, then the reference identification is reliable, but the manufacturing time and costs increase
Solution Approach 1:
The patent extracts and eliminates the marking generation and detection steps from the manufacturing process. Instead of adding markings to identify reference teeth or gaps, the method directly uses the geometric features of the already-machined first gearing to identify reference elements and establish angular positions for the second gearing, thereby removing unproductive manufacturing steps while maintaining identification reliability
Solution Approach 2:
The first gearing serves itself as the reference for the second gearing. The geometric features of the first gearing (teeth, gaps, or predetermined features) are directly used to identify reference elements and define angular positions, eliminating the need for separate marking systems. The component's own structure provides the necessary reference information
2Reliability
If markings are generated and detected to identify reference teeth or gaps, then the reference identification is reliable, but the device complexity increases
Solution Approach 1:
The patent removes the marking generation and detection devices from the manufacturing system. By using the geometric features of the first gearing directly as references, the method eliminates the need for specialized marking equipment, reducing device complexity while maintaining reliable reference identification
Solution Approach 2:
The geometric features of the first gearing serve multiple functions: they are both the machined feature and the reference feature for the second gearing. This multi-functionality eliminates the need for separate marking systems, reducing device complexity while maintaining identification reliability
3Manufacturing precision
If the component is reclamped after fine machining of the first gearing and before fine machining of the second gearing, then the second gearing can be machined with correct reference, but the manufacturing time increases
Solution Approach 1:
The method performs preliminary identification of reference teeth or gaps of the first gearing before reclamping. By measuring actual angular distances and assigning them to predetermined nominal angular distances in advance, the reference is established before the component is reclamped, reducing the time lost during reclamping operations while maintaining precision
Solution Approach 2:
The method uses feedback from measuring actual angular distances on the first gearing to identify reference elements. The measured data is used to assign nominal angular distances and establish precise angular positions for the second gearing, ensuring manufacturing precision while minimizing reclamping time through efficient reference identification
Data Source
AI summary
A hard finishing of a component, wherein the component has a first gearing and a second gearing, wherein a nominal angular position of the second gearing relative to the first gearing is defined for the component. The identification of a reference for achieving the nominal angular position is carried out by a pattern matching of measured actual angular distances to predetermined nominal angular distances.
