Pump Mounting Flange Layout for Flexible Engine Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pump systems face issues with lubrication, where oil in bearings can overheat and break down due to limited exchange with the primary oil reservoir, leading to reduced lubricating performance and accumulation of breakdown products, which can cause damage.
Innovation Solution
A dynamic lubrication system is implemented, where the cam plate's rotational motion imparts dynamic motion to oil within the primary oil reservoir, facilitating its migration through the bearing, refreshing the oil and removing breakdown products, thereby reducing heat buildup and extending lubricant life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pump mounting flange uses a symmetrical pattern of mounting holes, then the pump can be mounted in multiple orientations and positions, but the mounting holes must correspond to an asymmetrical engine flange pattern
Solution Approach 1:
The pump mounting flange incorporates two distinct sets of mounting holes: a first set arranged in a symmetrical pattern and a second set arranged in an asymmetrical pattern. This asymmetric design within the flange allows the pump to be mounted to engine flanges with different hole patterns, providing versatility while maintaining a relatively simple overall structure.
Solution Approach 2:
The mounting flange is designed with multiple sets of mounting holes that can accommodate different engine flange configurations. This multi-functional design allows a single pump model to be universally mounted to various engine types without requiring custom adapter plates, thereby improving adaptability without significantly increasing device complexity.
2Device complexity
If conventional static lubrication is used in bearings, then the structure is simple, but oil overheats and breaks down due to limited exchange with the primary oil reservoir
Solution Approach 1:
The lubrication system transitions from a static oil reservoir to a dynamic system where the cam plate's rotation actively circulates oil through the bearing. This dynamic motion continuously exchanges oil between the bearing and primary oil reservoir, preventing overheating and breakdown while maintaining structural simplicity by utilizing existing moving parts.
Solution Approach 2:
The system uses the cam plate's inherent rotational motion to drive oil circulation through the bearing without requiring additional pumps or complex mechanisms. The existing mechanical motion serves a dual purpose: driving the pump mechanism and circulating lubricant, thereby improving reliability without increasing device complexity.
