AI Technical Summary

Technical Problem

Conventional oil supply components for compressors face difficulties in attachment due to high resistance when inserting engagement claws into the oil supply hole of the rotating shaft, making it challenging to attach them efficiently, especially in low rotation ranges.

Method used

The oil supply component features a main plate portion with protruding insertion portions that have a specific geometry, where the connection point contacts the inner circumferential surface of the rotating shaft, reducing resistance and facilitating easier attachment by optimizing the diameter and angle of the insertion portions.

Benefits of technology

This configuration allows for easier attachment of the oil supply component to the compressor's rotating shaft, reducing resistance and improving the supply of refrigerating machine oil to sliding parts, even in low rotation ranges, enhancing the reliability and efficiency of the compressor.

Abstract

DEPCT67 The oil feeding components as disclosed herein include the main plate section, which contains... Creating holes in the area and more than one insertion point, each protruding. Exit from the main plate at a position near the outer perimeter of the plate. The principle is related to the passage hole, where more than one insertion site is inserted into the hole. Apply oil to the compressor's rotating shaft at each insertion point, including the base end. Which is connected to the main plate and the protruding end area on the terminal side. The area where insertion occurs in the case where an imaginary straight line passes through the passage hole and is perpendicular to the main plate section. Let there be a hypothetical straight line at the first point in the region where each connection is inserted, which is the location of the joint. The area where the base and the insertion point are connected is positioned away from... The first imaginary straight line is the maximum;
