Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Constructing toothed gears with external toothing and internal grooved profiles poses challenges in achieving high precision and productivity while minimizing processing errors and costs, particularly due to the need for multiple machine transfers that can lead to positioning errors and increased costs.
Innovation Solution
A machine tool with a rotating table and mandrel-type engagement devices allows continuous processing of workpieces with external toothing and internal grooved profiles, eliminating the need for machine transfers by using a combination of toothing and milling heads that maintain the workpiece engagement, ensuring precise positioning and simultaneous processing of multiple workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple machine transfers are used to process external toothing and internal grooved profiles separately, then specialized processing operations can be performed, but positioning errors occur and manufacturing precision deteriorates
Solution Approach 1:
The patent combines multiple processing operations (external toothing construction and internal grooved profile construction) into a single machine tool with a rotating table that can hold multiple workpieces. This allows both operations to be performed on the same workpiece without transfer, eliminating positioning errors and ensuring high concentricity while maintaining specialized processing capabilities through dedicated tooling stations.
Solution Approach 2:
The machine tool is designed with multi-functionality to perform both external toothing construction and internal grooved profile construction operations. The rotating table with multiple workpiece positions and interchangeable tooling allows the same machine to execute different specialized operations on the same workpiece, eliminating the need for multiple specialized machines while maintaining precision.
2Ease of manufacture
If multiple machine transfers are used for processing, then different processing operations can be performed, but processing time increases and productivity decreases
Solution Approach 1:
The patent implements continuous processing by eliminating machine transfers between operations. The rotating table allows workpieces to be sequentially processed for both external toothing and internal grooved profiles in a continuous flow without interruption or repositioning, maximizing productivity while maintaining full processing capability through coordinated tooling stations.
Solution Approach 2:
The machine tool is segmented into multiple independent processing stations arranged on a rotating table, each capable of performing specific operations. This segmentation allows different workpieces to be processed simultaneously at different stations, and enables continuous operation without idle transfer time, thereby increasing overall productivity while maintaining specialized processing functions.
3Ease of manufacture
If multiple machines are used for processing operations, then processing capability is enhanced, but device complexity and cost increase
Solution Approach 1:
The patent creates a universal machine tool that consolidates multiple specialized machines into one system. The rotating table with multiple workpiece positions and interchangeable tooling stations provides the capability to perform both external toothing and internal grooved profile operations, reducing the number of machines needed while maintaining full processing capability through multi-functional design.
Solution Approach 2:
The patent adds the dimension of time and sequence to the processing system by using a rotating table with multiple positions. Instead of having multiple machines operating in parallel space, the system uses sequential positioning and coordinated tooling to achieve the same processing capability, thereby reducing spatial complexity and machine count while maintaining full functionality.

AI summary
A machine tool for constructing toothed gears and components which are provided with external toothing and a grooved internal profile comprises a rotating table and a plurality of toothing heads and a plurality of milling heads, each of the toothing heads being arranged in alternation with a respective milling head along the perimeter of the rotating table. The workpieces to be processed are rotatably supported on the rotating table by means of mandrel type engagement devices which are rotatable about a secondary rotation axis parallel with the main rotation axis of the machine and which are configured in such a manner that the workpieces are gripped by the engagement devices with an axis of axial symmetry of the workpieces being aligned with the secondary rotation axis.
