Problems solved by technology

[0013] However, because the oil passage is long and narrow and installed upright inside the rotating shaft, the amount of oil needed to lubricate each friction starting device and cool the stator (121) cannot be fully supplied, and each friction starting device is due to friction or wear, damage, and due to The stator (121) is overheated, reducing the starting efficiency of the motor (120)

Embodiment Construction

[0058] The oil supply structure of the sealed scroll compressor will be described below with reference to the accompanying drawings.

[0059] As shown in the figure, the scroll compressor (1) in the present invention consists of the following parts. That is, the casing (10) that forms a sealed space inside; the compressor (30) that compresses the refrigerant inside the casing (10); the motor (20) that provides power to the compressor (30); The main frame (14) and the auxiliary frame (15) etc. which support the rotation shaft (23) of the motor (20) up and down.

[0060] Shell (10) is made up of following several parts. That is, a cylindrical housing main body (11) with openings at the upper and lower ends; an upper end cover (12) that seals the top of the housing and is connected with the housing main body; a lower end cover (13) that seals the lower end of the housing and is connected with the housing main body (11) )Wait.

[0061] The compressor (30) consists of a fixed sc...

Abstract

The invention belongs to compressor field, relates to a oil supply structure of scroll compressor. The technical project is: the rotating shaft fixed on the rotor center through the shaft hole of the assistant frame is combined to the dynamic scroll disk which can gear with the static scroll disk and compress the secondary refrigerant by the eccentric shaft, simultaneously, more than one screw group and oil guiding grooves for the oil draining holes are arranged along the inner side of the oil way which is formed along the length of the rotating shaft for transferring the lubricating oil stocked in the bottom of the casing to the friction surface on upper of the compressor by centrifugal action, The invention makes the lubrication oil supply more sufficient for compressor.

Description

technical field [0001] The invention belongs to the field of compressors and relates to an oil supply structure of a sealed scroll compressor. More specifically, it uses the centrifugal action of the rotating shaft to make the oil accumulated in the lower part of the casing more smoothly supplied to each friction surface. structure. Background technique [0002] Generally speaking, a hermetic scroll compressor consists of a motor and a compressor. The motor is used to generate rotational force in a sealed space; the rotational force generated by the motor is used to make the compressor suck in the refrigerant and discharge it after compression. According to the compression method of the compressor, it is divided into a reciprocating compressor, a rotary compressor, a scroll compressor, and the like. [0003] Hereinafter, a conventional scroll compressor according to the present invention will be described in detail with reference to the drawings. Fig. 1 is a longitudinal ...
