Gearing System Quality Assessment via Rotation Angle Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods, such as the double flank gear test, are inadequate for assessing the quality of gearing systems with multiple gear wheels, as they cannot automatically match toothed wheels or evaluate the interplay between them, limiting the determination of optimal distance and individual wheel quality.
Innovation Solution
A method and apparatus that measure and calculate angle of rotation differences between target and theoretical output angles of gear wheels, using transmission ratios to determine amplitude values representing the quality of the gearing system, allowing for optimal distance adjustment and identification of faulty components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the double flank gear test is used to test individual toothed wheels, then the quality of individual toothed wheels can be tested, but the interplay of the toothed wheels and the distance between them cannot be examined
Solution Approach 1:
The patent combines multiple toothed wheels into a single gearing system under test, rather than testing them separately. The method measures the cumulative angle of rotation of the entire gear system, thereby capturing the interplay between multiple toothed wheels and their relative distances simultaneously, resolving the limitation of the double flank gear test which can only examine individual wheels
2Manufacturing precision
If the double flank gear test is used, then toothed wheel form stability can be tested, but automatic matching of the distance between toothed wheels is not possible
Solution Approach 1:
The patent employs a feedback mechanism where the measured cumulative angle of rotation is compared against theoretically calculated values. The angle of rotation differences provide feedback information that enables automatic determination of optimal distances between toothed wheels, replacing the manual adjustment process and enabling automated matching while maintaining manufacturing precision requirements
3Adaptability or versatility
If multiple toothed wheels are used in a gearing mechanism, then complex movements can be achieved, but the quality determination becomes more difficult as individual wheel interplay cannot be assessed
Solution Approach 1:
The patent creates a universal measurement method that works for gearing systems with any number of toothed wheels. The single measurement of cumulative angle of rotation serves multiple functions: it assesses individual wheel quality, evaluates inter-wheel interplay, and determines optimal distances simultaneously, making the method applicable to complex multi-wheel systems without increasing measurement difficulty

AI summary
A method and an apparatus for determining the quality of a gearing system is described. The method includes the steps of setting a sequence of target angles of rotation of a first gear wheel, measuring for each of the target angles of rotation an output angle of rotation of a second gear wheel, and calculating a plurality of theoretical output angles of rotation. The method also includes obtaining angle of rotation differences between the plurality of output angles of rotation and the plurality of theoretical output angles of rotation, forming a sequence of cumulative values, and determining, based on the sequence, a first amplitude value, a second amplitude value or a third amplitude value.
