Solution Overview
Problem
The main shaft and bearing inner ring in compressors are prone to serious inclination due to the impact of suction airflow, leading to mechanical issues and reduced energy efficiency.
Innovation Solution
The design incorporates a convex portion on the main shaft with a slip sheet and a crescent-shaped air suction port that is positioned to minimize impact forces, ensuring the outer side does not exceed the cylinder's inner wall and the inner side does not exceed the convex portion's outer wall, resulting in reduced frictional forces during airflow entry, thereby reducing the inclination of the main shaft and bearing inner ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the air suction port is positioned to minimize impact forces on the main shaft, then the inclination of the main shaft is reduced, but the structural complexity of the air inlet and outlet device increases
Solution Approach 1:
The air suction port is designed with a specific spatial configuration including an outer side, inner side, and connecting side, positioning it in multiple dimensions relative to the cylinder and convex portion. This dimensional arrangement ensures the port is located on the inner side of the inner wall when the basic volume is maximum, minimizing impact forces on the main shaft while maintaining structural integrity
Solution Approach 2:
The convex portion with slip sheet acts as an intermediary element between the air suction port and the main shaft. The slip sheet converts relative sliding into rolling motion, reducing mechanical power consumption and minimizing the impact of suction airflow on the main shaft, thereby reducing main shaft inclination
2Stability of the object's composition
If the air suction port is positioned to minimize impact forces, then mechanical stability improves, but the energy efficiency gains are limited without additional design optimizations
Solution Approach 1:
The bearing inner ring is designed to replace pure sliding friction with rolling friction through the slip sheet mechanism. The slip sheet converts the relative sliding between the convex portion and inner wall into rolling motion, significantly reducing frictional losses and improving compressor energy efficiency while maintaining mechanical stability
Solution Approach 2:
The position of the air suction port is optimized based on the basic volume parameter of the cylinder. When the basic volume is at its maximum, the air suction port is positioned on the inner side of the inner wall, changing the spatial parameters to minimize impact forces on the bearing inner ring, thereby reducing inclination and improving energy efficiency
