Specific embodiment
Detailed description of the preferred embodiments below.It should be understood that described herein specific
Embodiment is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
The present invention provides a kind of compressors, and the compressor oil return is unimpeded, and have preferable lubricant effect.
The circulating within the compressor to the structure, working principle and lubricating oil of compressor of the present invention first below
Access does following explanation.
Referring to Fig. 1, compressor of the invention includes closed shell 13, and the crankshaft 7, dynamic being arranged in closed shell 13
Scroll plate 2, upper bearing (metal) 5, upper bracket 4 and oil return component 6 etc..
Wherein, upper bracket 4 is mounted on the top of closed shell 13；Fixed scroll 1 is provided on the upper surface of upper bracket 4,
Fixed scroll 1 is in close contact and protects including the upper surface of first end face 1b and the first scroll wrap 1a, first end face 1b and upper bracket 4
Hold sealing state；Orbiter 2 is arranged between upper bracket 4 and fixed scroll 1, and orbiter 2 includes second end face 2b and the
Two scroll wrap 2a, the second scroll wrap 2a engages to form compression chamber with the first scroll wrap 1a, and 4 inside second end face 2b and upper bracket
Boss between two spaces (higher first back pressure cavity 21 of pressure and pressure lower second is isolated by seal member 18
Back pressure cavity 22).
The middle part of closed shell 13 is provided with motor 12；The lower part of closed shell 13 is provided with lower bracket 10；Crankshaft 7 passes through
Upper bearing (metal) 5, lower bearing 11 are supported in closed shell 13, and the eccentric part 7d of crankshaft 7 is inserted into the tail bearing 3 of orbiter 2
It is interior；Oil Guide component 8 is equipped with the corresponding position of lower bracket 10 inside crankshaft.
The course of work of compressor is as follows: when compressor operation, motor 12 drives crankshaft 7 to rotate, and crankshaft 7 drives dynamic vortex
Disk 2 moves；Under the limitation of anti-rotation cross slip-ring 17, orbiter 2 is translatable around the center of crankshaft 7 with fixed radius
Movement, thus generated between the second scroll wrap 2a of orbiter 2 and the first scroll wrap 1a of fixed scroll 1 it is several mutually every
From and volume consecutive variations compression chamber；Row arrives the inside of closed shell 13 after the refrigerant gas of sucking compresses in compression chamber
In cavity, after through exhaust pipe 16 enter cooling cycle system.
The circulation flow passage of lubricating oil within the compressor are as follows:
The bottom of closed shell 13 is stored with enough refrigeration lubrication oil and compresses motor spindle with the rotary motion of crankshaft 7
Lubricating oil in oil sump enters the center oilhole 7b of crankshaft 7 through Oil Guide component 8.A part of lubricating oil into center oilhole 7b passes through
The lower bearing oilhole 7c of 7 lower part of crankshaft lubricates lower bearing 11, later along crankshaft 7 and lower bearing 11 gaps to flowing down
It returns in the oil sump of compression motor spindle；Most of lubricating oil into center oilhole 7b enters song from the upper end of center oilhole 7b
In the eccentric oilhole 7a on 7 top of axis, and flow up under the influence of centrifugal force, reach crankshaft 7 top area, later along
Gap between 7 eccentric part 7d of crankshaft and tail bearing 3 enters in the first back pressure cavity 21.
The lubricating oil that a part enters in the first back pressure cavity 21 can enter the by the seal member 18 with communication gap
Two back pressure cavities 22 enter compression chamber after being lubricated to anti-rotation cross slip-ring 17；And major part enters in the first back pressure cavity 21
The way to cycle oil that can be arranged on upper bracket 4 of lubricating oil flow downward, lubricate other components, pass through oil return component 6 later
It returns in the oil sump of compression motor spindle.
The present invention mainly improves the way to cycle oil being arranged on upper bracket 4, by the way that way to cycle oil is rationally arranged, makes
The running gear that the lubricating oil entered in the first back pressure cavity 21 is capable of sufficient lubrication compressor is obtained, the abrasion of running gear is reduced
Degree improves the working efficiency and service life of compressor；Meanwhile by the improvement of way to cycle oil, lubricating oil can be made suitable
Benefit flows back in the oil sump of compression motor spindle, has taken away the heat generated when the running gear friction of compressor, has enhanced heat dissipation effect
Fruit, and the pump housing that a large amount of refrigeration lubrication oil enters compressor is avoided, improve the refrigeration performance of compressor.
Mainly the way to cycle oil of compressor of the invention is described in detail below.It should be noted that following implement
The description of the orientation word such as upper and lower in example is using the placement position in embodiment 1 as reference.
