Description
Technical field
The present invention relates to a kind of oil supply structure, especially the oil supply structure of compressor.
Background technique
The scroll compressor of prior art as shown in Figure 1, it is configured to: the internal fixation with casing 1 of certain space has upper frame 2 and lower frame 3, and the electronic portion that comprises stator 4 and rotor 5 is arranged between upper frame 2 and the lower frame 3.Be pressed into running shaft 6 in the rotor 5, the top of running shaft 6 is eccentric part 6a.Upper frame 2 upper fixed have quiet whirlpool dish 7.Insert between upper frame 2 and the quiet whirlpool dish 7 and can carry out counterrotating movable orbiting scroll 8 with quiet whirlpool dish 7.The eccentric part 6a of running shaft 6 is connected with movable orbiting scroll 8, and the steel pin 9 that prevents movable orbiting scroll 8 rotations is arranged between movable orbiting scroll 8 and the upper frame 2.
Be thrust shaft bearing surface 2b on the body 2a of upper frame 2, the core of thrust shaft bearing surface 2b is the axle sleeve insertion groove 2c that the certain internal diameter and the degree of depth are arranged.Upper frame 2 is shaft insertion hole 2d with axle sleeve insertion groove 2c connecting part, and running shaft 6 inserts in the shaft insertion hole 2d.The oilhole 2e that is communicated with axle sleeve insertion groove 2c is arranged on the frame body 2a.Be to be the ring-like oil groove 2f that the center has the certain width and the degree of depth on the thrust shaft bearing surface 2b with axle sleeve insertion groove 2c.Be cotter way 2g on the marginal position above the frame body 2a, the pin of steel pin 9 inserts in the cotter way 2g.
In the movable orbiting scroll 8, on have the rotating disc 8d of certain thickness and area movable orbiting scroll sheet 8a, have below the rotating disc 8d and the relative thrust shaft bearing surface 8b of thrust shaft bearing surface 2b above the upper frame, the core of thrust shaft bearing surface 8b has the axle sleeve 8c that has certain internal diameter and highly protrude, axle sleeve 8c is inserted in the axle sleeve insertion groove 2c, the core of axle sleeve 8c has eccentric part insertion groove 8f, and the eccentric part of running shaft is inserted in the eccentric part insertion groove 8f.Be cotter way 8e below the rotating disc 8d, the pin of steel pin 9 is inserted in the cotter way 8e.
The axle sleeve 8c of movable orbiting scroll 8 inserts in the axle sleeve insertion groove 2c of upper frame, and the relative combination of thrust bearing 2b of the thrust shaft bearing surface 8b of movable orbiting scroll 8 and upper frame.In addition, running shaft 6 inserts in the shaft insertion hole 2d of upper frame, and the eccentric part 6a of running shaft 6 inserts in the eccentric part insertion groove 8f of movable orbiting scroll axle sleeve.
On the quiet whirlpool dish 7 separating plate 10 is arranged, separating plate 10 is divided into space, high pressure side and low voltage side space with the inner space of casing 1, be provided with between separating plate 10 and quiet whirlpool dish 7 and regulate the modulating valve 11 that the High Temperature High Pressure cold media air flows, the low voltage side space in the casing 1 links to each other with discharge tube 13 with suction pipe 12 respectively with the space, high pressure side.
A certain amount of machine oil is equipped with in the bottom surface of casing 1, and the end of running shaft 6 is connected with machine oil lifter 14, and the oil circuit 6b by 14 oil spouts of machine oil lifter is arranged in running shaft 6.
The working procedure of scroll compressor is as follows: at first, the compressor energising, start electronic portion, make rotor 5 rotations that constitute electronic portion, the rotating force that rotor 5 rotations produce sends movable orbiting scroll 8 to by the running shaft 6 that is pressed in the rotor 5, steel pin 9 prevents movable orbiting scroll 8 rotations, relative being rotated of static vortex disk sheet 7a of the movable orbiting scroll sheet 8a of movable orbiting scroll 8 and quiet whirlpool dish.By the rotation of movable orbiting scroll 8, cold media air is inhaled into the compression volume that forms between static vortex disk sheet 7a and the movable orbiting scroll sheet 8a through suction pipe 12 and the suction port that coils 7 one sides in quiet whirlpool.When cold media air moves to the center of compression volume, cold media air is compressed by the variation of compression space volume, cold media air after being compressed is discharged by the discharge port 7b on the quiet whirlpool dish 7, and the cold media air of the high-temperature high-pressure state of discharge discharges by discharge tube 13.
Rotation along with running shaft 6, the machine oil of casing 1 inner bottom surface is sucked by machine oil lifter 14, the machine oil that is sucked upwards promotes by oil circuit 6b, and a part is supplied with the part with running shaft 6 slide relative, and remaining machine oil flows out by the end of the engine oil passage 6b of running shaft 6.The machine oil that flows out flows between the inwall of the eccentric part 6a of running shaft and eccentric part insertion groove 8f, flow in the axle sleeve insertion groove 2c and upper frame on oil groove 2f in, supply between the thrust shaft bearing surface 8b of movable orbiting scroll and the thrust shaft bearing surface 2b on the upper frame.The oil that supplies to the thrust shaft bearing surface 8b of movable orbiting scroll and the thrust shaft bearing surface 2b on the upper frame flows back to the bottom surface of casing 1 again, in addition, flows into the interior machine oil of axle sleeve insertion groove 2c flows back to casing 1 by oilhole 2e bottom surface.
Shortcoming with scroll compressor of said structure is: along with the rotation of running shaft 6, the machine oil that is raised flow in the axle sleeve insertion groove 2c, supply with machine oil to the thrust shaft bearing surface 8b of movable orbiting scroll and the thrust shaft bearing surface 2b on the upper frame, so cotter way 8e below the rotating disc 8d of movable orbiting scroll, it is the supply that can not in time obtain machine oil in the cotter way 8e that inserts of the pin of steel pin 9, cause the startup of steel pin 9 successfully not carry out, wear and tear between the inwall of the pin of steel pin 9 and cotter way 8e simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of oil supply structure that can in time obtain the scroll compressor of engine oil supplying in the cotter way that makes.
In order to address the above problem, the technical solution used in the present invention is: a kind of oil supply structure of vortex compressor, comprise the eccentric part insertion groove of machine oil lifter, running shaft, running shaft oil circuit, movable orbiting scroll, the cotter way of movable orbiting scroll, it is characterized in that: be communicated with by the machine oil through hole between the eccentric part insertion groove of the cotter way of movable orbiting scroll and movable orbiting scroll.
The beneficial effect of the oil supply structure of scroll compressor of the present invention is; In compressor operation, the oil that oil circuit by running shaft promotes ejection is through machine oil through hole sufficient machine oil of supply between the pin of the cotter way of movable orbiting scroll and steel pin, make the cotter way of movable orbiting scroll and be inserted in moving of being well between the pin of the steel pin in the cotter way, reduce the wearing and tearing between them simultaneously, improve reliability.
