Grinding Roller Axial Oscillation via Single Motor Cam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding and deburring machines for flat workpieces require a second drive to independently control the rotational speed and oscillating frequency of the grinding roller, making them complex, expensive, and less reliable.
Innovation Solution
A single drive motor is used to both rotate and axially oscillate the grinding roller through a cam mechanism integrated with the drive shaft, allowing independent adjustment of the oscillating frequency and rotational speed without a separate motor for oscillation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a second independent drive is provided for the back-and-forth movement of the grinding roller, then the rotary speed and oscillation frequency can be selected and adjusted completely independently, but the machine becomes significantly more complicated and expensive
Solution Approach 1:
The patent combines the drive for rotational movement and the drive for axial back-and-forth movement into a single motor. The motor's rotational output is transmitted through a transmission mechanism that simultaneously produces both the rotation of the grinding roller and its axial oscillation, eliminating the need for a second independent drive while maintaining independent adjustability of both movements
Solution Approach 2:
A single motor is designed to perform multiple functions: it generates the rotational movement of the grinding roller and simultaneously produces the axial back-and-forth movement through an integrated transmission mechanism. This multi-functional approach reduces the number of separate drives required while maintaining full control over both motion parameters
2Adaptability or versatility
If a second independent drive is provided for oscillation, then rotary speed and oscillation frequency can be adjusted independently, but the machine becomes less reliable in operation
Solution Approach 1:
By merging the rotational drive and oscillation drive into a single motor system, the patent reduces the number of independent drive components that could potentially fail. The single motor with integrated transmission eliminates the complexity and potential failure points associated with having two separate drives, thereby improving reliability while maintaining independent control capabilities
3Adaptability or versatility
If a second drive is added for back-and-forth movement, then the machine can be more flexible in operation, but it becomes significantly more expensive
Solution Approach 1:
The patent merges the functions of two separate drives into a single motor system with an integrated transmission mechanism. This consolidation reduces the bill of materials, simplifies assembly, and lowers manufacturing costs while preserving the operational flexibility of independently adjusting rotational speed and oscillation frequency

AI summary
A device for grinding and deburring a flat workpiece comprise a grinding roller having an abrasive coating. A coaxial drive shaft that is connected rotation-fast to the guide roller is driven by a drive motor via a primary belt drive. The grinding roller is borne axially displaceable on the drive shaft. Via a second secondary belt drive, the drive motor drives a cam mechanism, comprising a control cylinder that is rotatably borne on the drive shaft of the grinding roller and that has a groove cam and comprising a cam slide arranged on the grinding roller. The rotating grinding roller thus performs an oscillating axial back-and-forth movement.
