Compressor Reducer Rib Guide for Insertion Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressors face issues with reducer damage and increased costs due to complex manufacturing processes and management of oil recovery passage dimensions, leading to potential clogging and inefficiencies in oil pressure reduction during the recovery process.
Innovation Solution
Incorporation of a deformation preventing unit, specifically rib parts on the reducer's shaft and spiral parts, to prevent damage during insertion into the oil recovery passage, simplifying the manufacturing process and reducing costs by ensuring the reducer's integrity and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the reducer is forcibly fitted into the oil recovery passage to reduce oil pressure, then the oil pressure reduction function is achieved, but the spiral part of the reducer may be damaged during insertion
Solution Approach 1:
The patent applies preliminary action by providing guide ribs on the reducer surface before insertion into the oil recovery passage. These guide ribs预先 (in advance) align the reducer with the passage and guide it during insertion, preventing misalignment and damage to the spiral part. This preliminary guiding action ensures the reducer is properly positioned before the force-fitting process begins, resolving the contradiction between achieving oil pressure reduction and maintaining reducer integrity.
2Reliability
If the dimensions of the oil recovery passage are strictly managed to prevent reducer damage, then the reducer integrity is maintained, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent applies self-service by designing the guide ribs on the reducer that automatically guide the component into the oil recovery passage during assembly. The guide ribs on the reducer itself perform the guiding function without requiring external fixtures or complex positioning mechanisms. This self-guiding capability simplifies the manufacturing process and reduces dimensional control requirements while maintaining reducer integrity.
3Productivity
If the reducer is designed with a spiral part for oil pressure reduction, then the oil recovery function is improved, but the reducer becomes susceptible to damage during insertion
Solution Approach 1:
The patent applies the intermediary principle by introducing guide ribs as a mediating structural element between the reducer and the oil recovery passage. These guide ribs act as an intermediary feature that facilitates proper alignment and insertion without transmitting damaging forces to the spiral part. The guide ribs absorb and distribute the insertion forces, protecting the vulnerable spiral structure while enabling the reducer to perform its oil pressure reduction function effectively.

AI summary
Disclosed herein may be a compressor. The compressor may include: a casing; a compression unit configured to suck refrigerant from a suction space of the casing, compress the sucked refrigerant, and discharge the compressed refrigerant to a discharge space of the casing; an oil recovery passage configured to recover oil separated from refrigerant in the discharge space to the suction space; and a reducer inserted into the oil recovery passage to reduce a pressure of oil passing through the oil recovery passage. The reducer may include a deformation preventing unit configured to prevent the reducer from being damaged when the reducer is inserted into the oil recovery passage. Therefore, the reducer may be prevented from being damaged when the reducer is inserted into the oil recovery passage. The costs required to prevent the reducer from being damaged, check the conditions of the reducer, and repair reducer may be reduced.
