It is rotatably fitted in compression chamber under the driving of crankshaft 31.Certainly, cam mechanism 30 or integral type.
As shown in figs 2-4, cylinder 10 is equipped with sliding vane groove 13, and slide plate 40 is installed on sliding vane groove 13, swinging block 50 and slide plate 40
Apex it is hinged around first axle, first axle is parallel with the axis of cylinder 10, swinging block 50 have compresses face 55, compress face 55 and support
The periphery of belling wheel portion, and the periphery inscribe in face 55 Yu cam part is compressed, in the rotary compressor course of work, support
It is slidably matched between pressure surface 55 and the periphery of cam part, forms sliding friction pair.
It should be noted that the apex of slide plate 40 refers to that slide plate 40 extend into the cam part in compression chamber close to cam mechanism 30
One end of the periphery of (piston 32).One end of swinging block 50 and the apex of slide plate 40 offset, the other end and cam machine of swinging block 50
The periphery of the cam part (piston 32) of structure 30 offsets.Swinging block 50, which has, compresses face 55, compresses the outer circle that face 55 compresses cam part
Face compresses the width that face 55 is greater than the apex of slide plate 40 along the width of the periphery circumferential direction of cam part.

Since the face 55 that compresses of swinging block 50 is arc-shaped, and the periphery inscribe in face 55 Yu cam part is compressed, in this way, swinging block
50 compress is easily formed oil film between face 55 and the periphery of cam part, and can maintain enough oil film thicknesses, so as to
To effectively reduce the contact area between swinging block 50 and the periphery of cam part, and then the friction damage of friction pair is effectively reduced
It loses.
Compressing face 55 is the arc surface that radius is r1, and the radius of the periphery of cam part is r2.
Inventor is had found by many experiments, for the rotary compressor of the utility model embodiment, works as satisfaction:
When 0.01%≤(r1-r2)/r2, compressing for swinging block 50 is easily formed oil film between face 55 and the periphery of cam part, and can be with
Enough oil film thicknesses are maintained, so as to effectively reduce the contact area between swinging block 50 and the periphery of cam part, in turn
The friction loss of friction pair is effectively reduced.
Inventor passes through many experiments discovery, relation curve such as Figure 34 of the COP of rotary compressor and (r1-r2)/r2
Shown, when (r1-r2)/r2 is too small, gap is too small between swinging block 50 and the periphery of cam part, and lubricating oil not easily passs through the gap
Oil film is generated in engaging friction is secondary, is had an adverse effect to COP；(r1-r2) oil film bearing capacity when/r2 is excessive, in friction pair
Decline also results in the by-produced metal contact of friction, has an adverse effect to COP.
When satisfaction: when 0.01%≤(r1-r2)/r2≤1%, such as (r1-r2)/r2=0.05%, or (r1-r2)/
R2=0.1%, or (r1-r2)/r2=0.5%, compressing for swinging block 50 are easily formed between face 55 and the periphery of cam part
Oil film, and enough oil film thicknesses can be maintained, so as to effectively reduce connecing between swinging block 50 and the periphery of cam part
Contacting surface product, and then the friction loss of friction pair is effectively reduced.
The area for compressing face 55 on increasing swinging block 50 can further decrease and compress face 55 and cam part on swinging block 50
Face pressure between periphery further decreases the outer circle for compressing face 55 and cam part on swinging block 50 to increase oil film thickness
Contact area between face reduces the friction loss of friction pair.
To increase the area for compressing face 55 on swinging block 50, then need to increase the width for compressing face 55.To avoid compressor
When operation, the sliding vane groove 13 of swinging block 50 and cylinder 10 generates interference, needs to open up on 10 sliding vane groove of cylinder, 13 corresponding position scarce
Mouth 12, if the notch 12 is provided at the corresponding sliding vane groove 13 of exhaust side, can generate clearance volume, the high pressure after having compressed
Refrigerant can remain in the escape groove, and 10 internal volume of cylinder is occupied after expansion, inspiratory capacity be reduced, to reduce compressor efficiency.
The width for compressing face 55 is wider, then 12 volume of notch for needing to open up on 10 exhaust side sliding vane groove 13 of cylinder is bigger,
Clearance volume is bigger, and compressor efficiency caused by clearance volume influences bigger.
The width for compressing face 55 is wider, and the oil film thickness compressed between face 55 and the periphery of cam part is thicker, and oil film is thick
After degree reaches the metal contact avoided completely enough between the friction pair to a certain degree, the width in the face of compressing 55 is further increased
The viscous loss that the oil film between friction pair can be increased instead, reduces the efficiency of compressor.
According to the rotary compressor of the utility model embodiment, 40 apex of slide plate and cam part outer circle are significantly improved
The stress of face contact, improves the lubricating status between slide plate 40 and cam part friction pair, and swinging block 50 compresses face 55 and cam
It is easily formed oil film between the periphery in portion, and enough oil film thicknesses can be maintained, so as to effectively reduce 50 He of swinging block
Contact area between the periphery of cam part, and then the friction loss of friction pair is effectively reduced.
In some embodiments, slide plate 40 with a thickness of t1, width of the swinging block 50 at the face that compresses 55 is t2, in other words,
One end width that swinging block 50 and the periphery of cam part offset is t2.
Inventor has found that the relation curve of the COP and t2/t1 of rotary compressor are as shown in figure 35 by many experiments,
For the rotary compressor of the utility model embodiment, when satisfaction: when 0.5≤t2/t1≤3, the COP of compressor is larger.Than
Such as t2/t1=1 perhaps t2/t1=1.5 perhaps t2/t1=2 or t2/t1=2.5.
