Description
Technical field
It the utility model is related to compressor field, and in particular to a kind of rolling rotor compressor with upper support.
Background technology
With the expansion in compressor application field, for the requirement more and more higher of the operational reliability of high-power compressor,
In order to improve the stability of such compressor, upper support structure generally is set in compression case body, the upper end of bent axle is subject to
It is fixed.
Rolling rotor compressor for being provided with upper support structure, in the prior art below crankshaft oil hole generally use
Two kinds of designs：
(1) as shown in Figure 1 and Figure 2, set in bent axle 3 along the axially extending straight oilhole 31 of bent axle 3, and on the straight oilhole 31
Plug cock 311 is installed from the one end of cylinder farther out, in this design, the straight oilhole 31 is through the logical of whole bent axle 3
Hole；
(2) as shown in Figure 3, Figure 4, the straight oilhole 32 and horizontal stroke oil that bent axle 3 is axially extended to along bent axle 3 are set in bent axle 3
Hole 33, horizontal oilhole 33 are opened between upper cylinder cover 6 and rotor 7, in this design, the straight oilhole 31 is not through whole
Bent axle 3, and extend near rotor 7；
It is subject to fixed effect, when bent axle 3 rotates, its appearance to the upper end of bent axle 3 because upper supporting part 11 can play
Face corresponding site contacts friction with the upper inner surface of supporting part 11.
Scheme (1) though in there is oil stream to go out at the top of bent axle, in terms of actual result can not to upper supporting part 11 and bent axle 3 it
Between contact surface carry out effectively lubricating；Horizontal oilhole 33 is opened between upper cylinder cover 6 and rotor 7 in scheme (2), mainly to upper cylinder cover
It is lubricated that effect is preferable between 6 and the contact surface of rotor 7, but can not has to the contact surface of upper supporting part 11 and bent axle 3
Effect lubrication.
In summary, both the above scheme of the prior art, for the contact surface between upper supporting part 11 and bent axle 3 compared with
Hardly possible realizes lubrication, it is impossible to effectively reduces friction therebetween, causes supporting part 11 relative with the contact surface abrasion of bent axle 3
It is more serious.
The content of the invention
In view of problems of the prior art, the purpose of this utility model is to provide a kind of rolling rotor compressor,
Upper supporting part and bent axle mating part can be lubricated, so as to reduce the abrasion of contact surface, improve rolling rotor-type pressure
The reliability of contracting machine.
The utility model provides a kind of rolling rotor compressor, including housing, be arranged at cylinder in housing, bent axle with
Piston, it is provided with bent axle along the first axially extending oilhole of bent axle, the upper supporting part for fixed crankshaft is provided with housing,
The second oilhole is additionally provided with bent axle, the second oilhole connects the Part I coordinated on the first oilhole and bent axle with upper supporting part
Outer surface.
Further, the first oilhole extends to Part I.
Further, axis of the axis of the second oilhole perpendicular to bent axle.
Compared with prior art, rolling rotor compressor provided by the utility model, has the advantages that：Set
Oil outlet is located at the horizontal oilhole of upper supporting part and bent axle mating part, and upper supporting part and bent axle mating part can be moistened
It is sliding, so as to reduce the abrasion of bent axle, improve the reliability of rolling rotor compressor.

Embodiment
As shown in Figure 5, Figure 6, the rolling rotor compressor of one embodiment of the present utility model, including housing 1, set
It is provided with the cylinder 2 in housing 1, bent axle 3 and piston 5, bent axle 3 along the first axially extending oilhole 34 of bent axle 3, housing 1
On be provided with upper supporting part 11 for fixed crankshaft 3, be additionally provided with the second oilhole 35 in bent axle 3, the second oilhole 35 connection the
The outer surface of the Part I 36 coordinated on one oilhole 34 and bent axle 3 with upper supporting part 11.
Rolling rotor compressor in the present embodiment, oil outlet 351 is set to be located at upper supporting part 11 and the auxiliary section of bent axle 3
The horizontal oilhole (the second oilhole 35) divided, the lubricating oil flowed out from oil outlet 351 can be to upper supporting part 11 and the mating part of bent axle 3
(Part I 36) is lubricated, and so as to reduce the abrasion of bent axle 3, improves the reliability of rolling rotor compressor.
In the present embodiment, the first oilhole 34 extends to Part I 36.
Axis of the axis of second oilhole 35 perpendicular to bent axle 3.
In the present embodiment, by taking Double-cylinder rolling-rotor type compressor as an example, but the utility model is not limited to the type
Compressor.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member makes many modifications and variations without creative work can according to design of the present utility model.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model in domain
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
