Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional meshing sensors fail to achieve precise alignment of gearings with chamfers due to difficulty in detecting tooth structures, leading to inaccuracies in rotational angular position alignment during machining of double gearings.
Innovation Solution
A method involving the identification of a reference tooth structure using a marking detection device or meshing sensors, followed by precise measurement with a tactile or optical sensor to determine the reference rotational angular position, allowing the second gearing to be machined in a predetermined relationship to the first gearing, ensuring precise alignment even with chamfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional meshing sensors are used to detect tooth structures, then the detection process is simple, but the measurement precision is insufficient to ensure precise alignment of gearings with chamfers
Solution Approach 1:
The patent applies preliminary action by first identifying reference tooth structures using marking detection devices or meshing sensors before performing precise measurement with tactile or optical sensors. This preliminary identification step prepares the system by locating key reference points on the gear teeth, enabling subsequent high-precision measurement and alignment operations to be performed accurately even on gears with chamfers
Solution Approach 2:
The patent uses tactile sensors or optical sensors as intermediary measurement devices that can accurately detect tooth structures with chamfers. These sensors serve as mediators between the challenging measurement target (teeth with chamfers) and the control system, translating physical tooth positions into precise rotational angular position data that enables accurate alignment
2Measurement precision
If multiple sensors and measurement devices are used to achieve precise alignment, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a positioning device where multiple sensors (marking detection devices, meshing sensors, tactile sensors, optical sensors) can perform different functions within a single integrated system. The same device can identify reference tooth structures, measure precise positions, and control alignment operations, reducing the need for separate dedicated devices for each function
Solution Approach 2:
The patent merges multiple measurement and detection functions into a single integrated positioning device. By combining marking detection capabilities, meshing sensor detection, tactile measurement, and optical measurement in one unified system, the patent achieves high-precision alignment while managing device complexity through functional integration rather than separate independent systems
3Manufacturing precision
If conventional machining methods are used without precise positioning, then the machining process is simple and fast, but manufacturing precision of gear alignment deteriorates
Solution Approach 1:
The patent applies preliminary action by performing reference tooth structure identification and precise measurement operations before the actual machining of the second gearing. This preliminary positioning and measurement phase establishes accurate rotational angular position data that guides the subsequent machining process, ensuring high manufacturing precision without requiring complex adjustments during machining
Solution Approach 2:
The patent implements feedback by using measured rotational angular position data from reference tooth structures to control and adjust the machining process. The measurement system provides real-time or near-real-time position information that feeds back to the control system, enabling dynamic adjustment of machining parameters and tool positions to maintain high precision alignment between the first and second gearings

AI summary
In a method of machining a workpiece (60) having first and second gearings (61, 62), a reference tooth structure of the first gearing (61) is identified. The reference tooth structure is then measured with a reference measuring device (140) to determine a reference rotational angular position of the workpiece. Subsequently, the second gearing (62) is machined in such a way that the second gearing obtains a rotational angular position which is in a predetermined relationship to the determined reference rotational angular position.
