Existing drive assemblies for necker machines are shaft-based, leading to issues such as expensive and prone-to-failure lubrication systems and significant downtime for repairs, especially when drive elements are difficult to access.
Innovation Solution
A drive assembly for a necker machine that includes a plurality of motors with output shafts, drive wheel assemblies operatively coupled to the machine's drive shafts, and timing/drive belts operatively coupled to each drive wheel assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shaft-based drive assembly is used, then the processing stations can be linked to a motor, but the lubrication system becomes expensive and prone to breakdown
Solution Approach 1:
The patent removes the lubrication system entirely by replacing the shaft-based drive assembly with a belt-driven system. The timing belts transmit power from motors to drive shafts without requiring lubrication, extracting the problematic lubrication component from the drive system while maintaining the essential power transmission function.
Solution Approach 2:
The patent substitutes the mechanical shaft-based drive system with a belt-driven system. Instead of using rigid shafts that require lubrication, the invention uses timing belts and pulleys to transmit rotational motion, replacing the mechanical contact-based power transmission with a friction-based belt drive system that eliminates the need for lubrication.
2Productivity
If a shaft-based drive assembly is used, then the processing stations can be linked to a motor, but downtime for repairs increases when drive elements are difficult to access
Solution Approach 1:
The patent creates a standardized modular drive assembly where each processing station has an identical belt-driven configuration. This homogeneity allows for interchangeable components and standardized maintenance procedures, reducing repair downtime by enabling quick replacement of belts and drive elements without custom fabrication or complex disassembly.
Solution Approach 2:
The drive assembly is segmented into modular units, with each processing station having its own independent motor and belt-driven drive shaft. This segmentation allows individual stations to be maintained or repaired without affecting other stations, minimizing overall machine downtime through localized maintenance activities.
3Productivity
If the number of processing and forming stations is increased, then more forming operations can be completed, but the machine becomes more complex and less desirable
Solution Approach 1:
The belt-driven drive shafts are designed to be universally applicable across multiple processing stations. A single motor can drive multiple processing stations through the belt system, and the same drive assembly configuration can be used for different forming operations, reducing overall system complexity while maintaining high productivity through multi-functional capabilities.
