AI Technical Summary

Technical Problem

Existing scroll compressors face limitations with grease lubrication, allowing only limited rotor speed and gas flow, requiring frequent maintenance, while oil lubrication systems suffer from insufficient oil circulation leading to potential damage and reduced lubrication effectiveness.

Method used

A scroll compressor design with an oil chamber located at a radial distance from the rotor's center, connected by a narrow oil channel to lubricate the central bearing, enhanced by a fan-cooled oil chamber and oil collector to ensure consistent lubrication and cooling.

Benefits of technology

The design achieves improved lubrication and reduced maintenance needs by maintaining effective oil circulation and cooling, allowing higher rotor speeds and gas flow rates without separate cooling circuits.

Abstract

A scroll compressor comprises a housing (2) with a fixed stator; a movable rotor (8); and a crankshaft (9) having a main shaft (14) and a secondary shaft (16) mounted on bearings at the center of the rotor (8) by means of a bearing (17); the rotor (8) being provided with an oil chamber (36) filled with oil (46) so that after the movement of the rotor (8), the oil (46) is lifted to lubricate the bearing (IV), characterized in that the oil chamber (36) is located at a radial distance (A) from the center of the rotor (8) and is connected to the bearing (17) by a narrower oil channel (37).
