Coupling Part Annular Groove Machining Without Deburring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing rotationally symmetrical parts, such as coupling parts, require additional manufacturing steps and deburring processes, which increase effort and complexity, especially when creating annular grooves and machining surfaces.
Innovation Solution
A coupling part design featuring a rotationally symmetrical area with an annular groove on its radially outer surface, where the groove is machined during turning, allowing for simultaneous production of the groove and machining surface without the need for separate deburring, and incorporating a claw coupling with an axially protruding area to facilitate oil management and detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an annular groove is created after initial turning and surface machining, then the groove can be produced with precision, but additional manufacturing steps and deburring are required
Solution Approach 1:
The annular groove is created during the initial turning operation before surface machining, rather than after. This preliminary action eliminates the need for subsequent deburring steps and reduces manufacturing process complexity while maintaining groove precision through proper tool setup and cutting parameters
2Ease of manufacture
If an annular groove is machined into the coupling part during turning, then deburring is eliminated, but the groove must be created in the same setup as the machining surface
Solution Approach 1:
The annular groove creation and machining surface production are merged into a single turning operation setup. The groove is machined concentrically with the surface in the same clamping and tool configuration, eliminating deburring while avoiding the need for separate setups or operations
3Manufacturing precision
If the machining surface is produced by milling, then a flat surface with normal direction parallel to the axis of symmetry is achieved, but run-out edges and burr formation occur
Solution Approach 1:
The annular groove is created during the initial turning operation before surface machining, rather than after. This preliminary action eliminates the need for subsequent deburring steps and reduces manufacturing process complexity while maintaining groove precision through proper tool setup and cutting parameters
4Manufacturing precision
If multiple manufacturing steps are used for creating annular grooves and machining surfaces, then each feature can be optimized, but productivity decreases
Solution Approach 1:
The annular groove creation and machining surface production are merged into a single turning operation setup. The groove is machined concentrically with the surface in the same clamping and tool configuration, eliminating deburring while avoiding the need for separate setups or operations
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
This approach simplifies the production process by integrating annular groove creation into the turning operation, reducing the need for deburring and enabling efficient oil management through the annular groove's role as a throwing edge for lubricating oil, while also allowing for the detection of oil leaks.
Implementation Method 1
is then flung off the annular groove by the centrifugal force exerted on the lubricating oil by the coupling component, which rotates during operation
