Embodiment
Below in conjunction with attached drawing 2 to Fig. 5 to the utility model proposes Rotary Compressor and its oil guard and the oily part of gear
It is described in further detail.It should be noted that attached drawing uses using very simplified form and non-accurate ratio, only use
With purpose that is convenient, lucidly aiding in illustrating the utility model embodiment.
Fig. 2 is the structure diagram for the oily part of gear that one embodiment of the utility model provides, and Fig. 3 is the gear oil part shown in Fig. 2
Sectional view at A-A lines.As shown in Figures 2 and 3, the oily part 10 of the gear is suitable for compressor, is particularly suitable for swinging
Compressor.The through hole 11 of upper and lower surface is provided through on the gear oil part 10, alternatively, is opened up in the center of the oily part 10 of gear described
Through hole 11.Especially, the oily part 10 of gear at the through hole 11 to side formed with a turnup structure 12.
So, a kind of Rotary Compressor includes housing, electric machine assembly, compression assembly, upper shell cover and lower cover.The electricity
Inside housings, the electric machine assembly is made of motor stator and rotor 21, the pressure for thermomechanical components and compression assembly installation
Contracting component includes cylinder, bent axle 22, piston and blade, and the piston is connected and is engaged with blade, institute with the eccentric part of bent axle
Blade is stated to be used for being spatially separating as suction muffler and discharge chamber in cylinder.
Wherein, the upper surface of rotor 21 is stretched out (i.e. away from compression group in one end (being defined as upper end) of the bent axle 22
One end of part), the upper end of the bent axle 22 mainly connects a supporting structure, which is used in structural support bent axle
22.The other end connection cylinder of the bent axle 22, the other end of the bent axle 22 are defined as lower end.And the swinging compression
Machine further includes oil guard, which includes above-mentioned gear oil part 10.
As shown in figure 4, during actual installation, the oily part 10 of gear is just arranged at the upper end surface of rotor 21, and described
The upper end of bent axle 22 is also through keeping off the through hole 11 of oily part 10, while the end of the turnup structure 12 of the oil baffle 10 is resisted against electricity
On the upper surface of machine rotor 21, and the upper surface of turnup structure 12 and rotor 21 is set to fit closing, with this to the electricity
Exhausting-gas hole 23 on machine rotor 21 is blocked.Obviously, the gas outlet of the exhausting-gas hole 23 is just located at the periphery of turnup structure 12,
In this way, be directly entered from the refrigerant that exhausting-gas hole 23 flows out in the exhaust space 13 of the oily part 10 of gear, it is cold in the exhaust space 13
Matchmaker can realize Oil-gas Separation, recycle oil droplet according to this, lift the oily cyclic utilization rate of compressor.
However, also can be as shown in figure 5, formed with a groove on the upper surface of the rotor 21 during actual installation
(not identifying), a part of size of the turnup structure 12 of the oily part 10 of gear are inserted into the groove, and then with the groove and wearing
Bent axle 22 in the groove fits closing, and same achievable bent axle 22 is isolated with exhausting-gas hole 23.
Preferably, balance weight 24, the gear oil are provided between the upper surface of the oily part 10 of the gear and the rotor 21
Part 10 is directly fixed with 24 phase of balance weight.Alternatively, multiple mounting holes 14, such as four are provided with around the through hole 11
A mounting hole 14, four mounting holes 14 are circumferentially evenly arranged, and each mounting hole 14 can intert a fastener and will balance
Block 24 is locked with the oily part 10 of gear.
With continued reference to Fig. 3, the turnup structure 12 has 121 He of first segment successively in the present embodiment, along flange direction
Second segment 122, and the cross sectional dimensions of the first segment 121 is more than the cross sectional dimensions of second segment 122, so convenient processing,
And the area that through hole 11 is in contact with bent axle 22 can be reduced, in order to assemble the oily part 10 of gear.Wherein, the second segment 122
Can be right angle flange, for being engaged with bent axle 22, but the hole size of the second segment 122 does not limit particularly, as long as
Can allow for bent axle 22 by, i.e., it is either large or small harmless, still can to the gas outlet of exhausting-gas hole 23 and bent axle 22 into
Row isolation.In addition, the first segment 121 can also be right angle flange.
Further, need to suitably be lengthened for the gear oil part 10 of insertion groove, the flange height of the second segment 121, so that
Can be after groove be inserted into, in the upper end surface of the oily part 10 of gear and rotor 21 formed with the exhaust space 13.More into one
Step, the oily part 10 of gear is a sheet metal component, and the Rotary Compressor can be rolling type compressor.
Finally, above-described embodiment has carried out in detail the oil guard of the utility model using Rotary Compressor as signal
Bright, to be converted on the basis of any oil guard provided in above-described embodiment content is provided in detail, belongs to the utility model institute
The scope of protection, those skilled in the art can draw inferences about other cases from one instance according to the content of above-described embodiment.
In conclusion the oily part of gear of the utility model is provided with the through hole that permissible bent axle passes through, and the oily part of the gear in
The through hole is also formed with can fitting with rotor the turnup structure of closing, and such oily part of gear can be to rotor
On exhausting-gas hole effectively blocked, can preferably isolate the gas outlet of bent axle and exhausting-gas hole, so that oil gas be better achieved
Separation, and the oily part of such gear is convenient for assembly.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Calmly, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content, belonging to right will
