Reversible Skiving Tool for Longer Gear Blank Cutting Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable skiving tools used for gear wheel processing have a limited lifespan due to wear, leading to increased costs and waste, as they cannot be reused effectively.
Innovation Solution
A reversible skiving tool design with two identically designed processing sides and a coupling device that allows the tool to be fastened to a skiving machine in two positions, enabling continued use after the first cutting edges wear out by switching to the second cutting edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If disposable skiving tools are used, then acquisition costs are lower, but the tool cannot be reused after reaching wear limit
Solution Approach 1:
The skiving tool is segmented into two identical processing sides, each with its own cutting edges. When one side's cutting edges wear out, the tool can be flipped to use the other side, effectively doubling the tool's useful life while maintaining the simplicity and low cost of disposable tool design
Solution Approach 2:
The tool design adds a second dimension of usability by creating two identical functional surfaces on the tool body. This allows the tool to be used from both sides, extending its service life without increasing acquisition costs or complexity
2Loss of substance
If reusable skiving tools are used, then resource sustainability is improved, but acquisition costs and reprocessing costs increase
Solution Approach 1:
The invention applies the disposable tool concept but extends its life through dual-sided design. The tool remains simple and low-cost to manufacture while achieving extended usability, avoiding the need for expensive reusable tools and their associated reprocessing costs
3Duration of action of moving object
If a skiving tool has two processing sides, then useful life is doubled, but device complexity increases
Solution Approach 1:
Both processing sides of the tool are designed identically with the same cutting edge geometry and tooth configuration. This homogeneity ensures that the tool performs equally well on both sides while keeping the design simple and easy to manufacture, minimizing the increase in device complexity

AI summary
The invention relates to a skiving tool which is designed as a disposable tool and which includes a first front side, a second front side, a toothing formed on its circumference and having teeth. The front surfaces assigned to the first front side are each delimited by a first cutting edge, as well as a coupling device for coupling the skiving tool to a tool spindle of a skiving machine. In order to enable an extended use in the case of such a skiving tool, the invention provides that the skiving tool has the basic shape of a cylindrical disc, that the front surfaces of the teeth assigned to the second front side are each delimited by a second cutting edge, and that the coupling device for use enables coupling of the skiving tool to the tool spindle such that the cutting edges assigned to its first front side come into engagement with the gear wheel to be processed, and enables coupling of the skiving tool to the tool spindle such that the cutting edges assigned to its second front side come into engagement with the gear wheel to be processed. During use, when the first cutting edges have reached their wear limit, the skiving tool is turned and skiving processing is continued with the same skiving tool until the second cutting edges have also reached their wear limit.
