た。(b) Conventional technology Conventionally, this type of compressor oil supply system was used, for example, in
As disclosed in Japanese Patent No. 15270, etc., it is composed of a cylindrical oil pickup formed by press-drawing an iron plate or iron pipe, and a paddle formed by cutting and bending a thin sheet metal. The paddle was inserted and held in the oil piston by its own elastic force, and was press-fitted into the oil hole of the rotating shaft. By allowing the lubricating oil to rise along the slope of the paddle and the constriction surface of the oil pick-up, the centrifugal pump action of the rotating shaft is enhanced and the lubrication characteristics are improved.

As disclosed in Japanese Patent Application Publication No. 2003-110029, a system in which a paddle and an oil pisoquanope are integrally formed using a synthetic co-fabric material has already been proposed. According to such a configuration, the work of the paddle and the oil pickup x, n (, 1) is not required, so the number of work steps is reduced.

トを高騰させるものであった。。However, synthetic resin oil pickups suffer from thermal creep due to the high heat generated during compressor operation, so when installing them on the rotating shaft, they cannot be held in place simply by press-fitting them into the oil chamber; instead, a separate spring or other component is required. In this case, it is necessary to fix the spring by using a spring locking groove on the outer circumferential surface of the rotating shaft, which increases the number of parts and the number of man-hours and increases the cost. .

The oil pickup is equipped with an oil pickup whose tip is immersed in oil to enhance the centrifugal pump action, and the oil pickup has a spiral groove on the inner circumferential surface so that the oil increases the thrust along the rotational direction of the rotating shaft. It is made of an extruded metal tube, one end of which is drawn, and the other end press-fitted into the oil chamber of the rotating shaft.

し、製造コストを低減できるものである。(e) Function The compressor oiling device of the present invention has the above-described configuration, and since the oil pickup can be formed from a ready-made extruded metal tube having a spiral groove on the inner circumferential surface, the oil-scorching effect can be enhanced. Not only can the number of man-hours be reduced, but since the pickup is made of metal, it can be firmly attached to the rotating shaft simply by press-fitting the pickup into the shaft hole, making assembly easier without the need for separate fixing devices such as springs. This makes it possible to improve workability and reduce manufacturing costs.

ックアップ７は完成される。1 is a hermetic compressor in which a compressor section 3 and an electric motor section 4 for driving the compressor section 3 are housed in a closed case 2 in which lubricating oil is stored at the bottom, and these two sections 3 and 4 are connected by a rotating shaft 5. It is. Reference numeral 6 denotes an oil chamber formed in the axial direction of the rotating shaft 5. 7 has spiral fins 8 on the inner peripheral surface by extruding steel material.
This oil pickup is made of a tube with a diameter formed therein, and one end of which is drawn to form a reduced diameter portion 9. This pickup is arranged so that the rotating shaft 5 is immersed in oil so that the reduced diameter part 9 is
It is press-fitted and fixed into the oil chamber 6 of. The method for manufacturing the oil pickup 7 will be briefly explained below. First, a copper (aluminum or the like) material is placed in a cylinder and strongly compressed by a ram, and the material is forced outward through a die hole under constant pressure to form a tube with a similar cross-section. After this (referred to as a continuous extrusion method), one end of the tube is drawn into a tapered shape to complete the oil pickup 7.

きる。In the compressor oil supply system configured as described above, the oil pickup 7 has spiral fins 8 formed by extrusion molding of steel material.
Since it is integrally formed, there is no need to assemble a paddle or the like to the oil pickup 7, and the spiral fins 8 can enhance the oil lifting action of the rotating shaft 5 while reducing the number of work steps. In addition, since the oil pickup 7 is made of metal, it can be firmly attached to the rotating shaft 5 simply by press-fitting the pickup into the shaft hole 6. This eliminates the need for assembly, making assembly work easier and reducing manufacturing costs.
