To realize the separation between refrigerant and lubricating oil, the oil spitting amount of rotary compressor 100 is reduced.In the other of the present invention
In embodiment, first end 511 can also be located at both ends or the other positions of the first side wall 52.
Further, groove 51 is along linear extension.As a result, when rotary compressor 100 works, balance weight A is adjoint to be turned
Son 31 rotate, convenient for lubricating oil under the influence of centrifugal force, thrown away out of groove 51, to significantly more efficient realizations lubricating oil with
Separation between refrigerant.That is, the intersection point along extending direction and 31 diameter of rotor of groove 51 is located in the rotation of rotor 31
At position other than heart line.
According to one embodiment of present invention, at least one of the first side wall 52 and second sidewall 53 are formed as arcwall
Face.Facilitate the fixed installation between balance weight A and rotor 31 as a result,.As shown in Figure 3, the first side wall 52 and second of balance weight A
Side wall 53 is all formed as curved wall.In the other embodiment of the present invention, second sidewall 53 may be formed as other
Shape.
According to one embodiment of present invention, at least one of balance weight A and balance weight B are riveted with rotor 31.As a result,
Balance weight A and balance weight B can be made simply and easily to be mounted on 31 end face of rotor, also, installed solid and reliable.Such as Fig. 2
It is shown, it is provided with rivet hole 54 on balance weight A, balance weight A can be stably fixed on 31 end face of rotor by rivet 11.
As shown in Figure 2, according to one embodiment of present invention, between balance weight A and rotor 31 and/or balance weight B with
Gear magnetic partition board 7 is equipped between rotor 31.That is, can be that gear magnetic partition board 7 is provided between balance weight A and rotor 31,
Can be that gear magnetic partition board 7 is provided between balance weight B and rotor 31；Certainly it can also be between balance weight A and rotor 31, balance
Gear magnetic partition board 7 is equipped between block B and rotor 31.Thus, it is possible to prevent the magnetic of balance weight A and balance weight B interference electric machine assemblies 3
, to ensure electric machine assembly 3 stability and high efficiency work, improve rotary compressor 100 overall performance.
Rotary compressor 100 according to the present invention is described in detail with a specific embodiment referring to Fig. 1-Fig. 6.
It is worth understanding, it is described below to be merely illustrative, rather than to the concrete restriction of the present invention.
As shown in Figure 1, rotary compressor 100 includes：Shell 1, compression assembly 2 and electric machine assembly 3.
Wherein, compression assembly 2 is located in shell 1, and electric machine assembly 3 is located in shell 1 and includes rotor 31 and stator 32, turns

Electric machine assembly 3 is rotated with dynamic crankshaft 4, and the rotation of bent axle 4 is to drive compression assembly 2 to compress refrigerant, compressed refrigerant
It is discharged from gas outlet 10.During compression mechanism moves, the abrasion between two components in order to reduce relative motion needs
Lubricating oil is added into compression mechanism, in order to realize efficiently separating between refrigerant and lubricating oil, reduce rotary compressor 100
Oil spitting amount, groove 51 can be set on balance weight A 5.
As shown in figure 3, the upper surface of balance weight A is equipped with groove 51, from the radially inner side of rotor 31 to radial outside
On direction, balance weight A has the 53 equal shape of the first side wall 52 and 53 the first side wall 52 of second sidewall and second sidewall being oppositely arranged
As curved wall, groove 51 penetrates through the first side wall 52 and second sidewall 53 and along linear extension.Groove 51 is located at the first side wall
52 and second sidewall 53 on both ends be respectively first end 511 and second end 512, first end 511 is in the first side wall 52
Portion.On 31 direction of rotation of rotor, first end 511 is located at the downstream of second end 512.
It is measured through overtesting, after the upper surface of balance weight A setting fluted 51, the oil spitting amount W of rotary compressor 100
Apparent improvement has been obtained with performance Y.Fig. 7 is according to the beneficial of the oil spitting amount W of the rotary compressor 100 of the embodiment of the present invention
Design sketch, it can be seen from the figure that the oil spitting amount W (in Fig. 7 shown in D) after balance weight A setting grooves 51 is not arranged than balance weight A
The apparent obtained reductions of oil spitting amount W (in Fig. 7 shown in C) when groove 51.Fig. 8 is the rotary compressor of the embodiment of the present invention
100 performance Y (COP) advantageous effect figure, it can be seen from the figure that rotary after groove 51 is arranged on the end face of balance weight A
Performance Y (Fig. 8 of rotary compressor 100 when groove 51 is not arranged compared with balance weight A by the performance Y (in Fig. 8 shown in F) of compressor 100
Shown in middle E) it is significantly improved.
As a result, by the way that groove 51 is arranged on 31 end face of rotor in balance weight A, when rotary compressor 100 works,
Balance weight A rotates together with rotor 31, at this point, the gaseous coolant for being mixed with lubricating oil can be from groove 51 in the first side wall 52
On opening enter in groove 51, and flowed out to outside groove 51 by opening of the groove 51 in second sidewall 53, due to
Lubricating oil is different with the density of gaseous coolant, under the influence of centrifugal force, can effectively detach lubricating oil and gaseous coolant,
So as to reduce the oil spitting amount of rotary compressor 100, the overall performance of rotary compressor 100 is improved.
