Dual Double-Action Can Body Maker Bearing Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional one-way double-action can body makers experience high impact loads on main bearings due to inertial and reaction forces, leading to reduced service life and increased energy consumption, as they rely on a single ram drive mechanism and hydrodynamic journal bearings.
Innovation Solution
A dual double-action can body maker design featuring two identical ram drive mechanisms sharing a crankshaft, with each mechanism operating in opposite directions to balance inertial and reaction forces, reducing the load on the crankshaft's support bearing and optimizing energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single ram drive mechanism is used in a one-way double-action can body maker, then the device complexity is reduced, but the impact load on the main bearing increases significantly
Solution Approach 1:
The patent combines two identical ram drive mechanisms into a single integrated system sharing one crankshaft. The two mechanisms work simultaneously in opposite directions, merging their force-balancing functions to reduce the impact load on the main bearing while maintaining the simplicity of a unified drive system.
Solution Approach 2:
The patent employs counterbalancing by arranging two identical ram drive mechanisms to operate in opposite directions. The inertial forces and reaction forces generated by each mechanism counterbalance each other, significantly reducing the net impact load on the main bearing supporting the crankshaft.
2Ease of manufacture
If a single ram drive mechanism is used, then the manufacturing cost is lower, but the service life of the bearing is reduced
Solution Approach 1:
The patent merges two force-balancing mechanisms into a single integrated drive system, achieving the force balance effect that extends bearing service life while avoiding the need for separate mechanisms, thus controlling manufacturing costs.
Solution Approach 2:
The counterbalancing arrangement reduces the impact load on the bearing through force cancellation, which directly extends the service life of the bearing. This approach is more cost-effective than using higher-grade bearings or complex lubrication systems.
3Use of energy by moving object
If a single ram drive mechanism is used, then the energy consumption is higher, but the device structure is simpler
Solution Approach 1:
The patent combines two drive mechanisms into one integrated system that shares a crankshaft and operates in opposition. This merging achieves energy efficiency through force balance while maintaining structural simplicity through the unified design.
Solution Approach 2:
The counterbalancing operation of the two mechanisms reduces the net force that the drive motor must overcome, thereby reducing energy consumption. The opposite-direction operation creates a naturally balanced system that requires less energy input.
