Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as to this practicality
New restriction.
Fig. 1 to Fig. 8 is refer to, the oil guard in the utility model can be used in rotor assembly, it includes body 1, slides
Block 2 and flexible member 3.For example, pie structure of the body 1 in cylinder, flexible member 3 can provide elastic force, to balance rotor
The centrifugal force that sliding block 2 is produced when component rotates.
Wherein, sliding block 2 is movably arranged as on body 1, and can moving radially along body 1.Body 1 has one or many
Individual air inlet 4, these air inlets 4 are arranged on the motion path of sliding block 2.Flexible member 3 is arranged on body 1, in this practicality
When oil guard in new remains static, flexible member 3 provides an active force to sliding block 2, so as to drive sliding block 2 to keep off
Live in gas port 4；When the oil guard in the utility model rotates, sliding block 2 gradually overcomes elastic unit under the influence of centrifugal force
Part 3 is applied to the active force on sliding block 2, so as to be moved radially outwards, air inlet 4 is exposed.Due to the size of centrifugal force
It is related to rotating speed, therefore according to different rotating speeds, the centrifugal force size of generation is also different, the size that air inlet 4 is exposed
Also it is different.
By the sliding block 2 on oil guard, rotor circulation area can be made to change with compressor operating frequency and change.Example
Such as, in compressor low-frequency operation, rotor speed is low, and compressor does not need larger circulation area, and sliding block 2 blocks opening, subtracts
The refrigeration oil of outflow compressor is lacked；With the rising of compressor operating frequency, sliding block 2 slides in and out, and circulation area gradually increases
Plus, so as to ensure that the circulating rate of refrigerant.
It can be seen that, the oil guard in the utility model can be such that rotor circulation area is adapted with the operating condition of compressor,
Specifically, refrigerating capacity it is small, do not need books circulation area when, reduce rotor assembly circulation area, so as to reduce cold
Frozen oil is lost in；When refrigerating capacity is big, increase circulation area, it is ensured that refrigerant circulating rate.
In a preferred embodiment, the utility model opens up one on the end face away from rotor core side of body 1
Individual annular groove 5, and air inlet 4 is arranged at the position corresponding with the opening on rotor core on the bottom surface of annular groove 5, with
Just refrigerant flows through.So, can also be that sliding block 2 provides installing space by annular groove 5.
In the embodiment shown in Figure 2, be formed with the chute 6 of radial direction on the lateral wall of annular groove 5, a part for sliding block 2 with
The gap of chute 6 coordinates, and is movably arranged as in chute 6.Chute 6 can be during sliding block 2 be moved, the motion to sliding block 2
A guide effect is played, makes it by predetermined movement path, so as to adjust the aperture of air inlet 4 exactly.More preferably
Ground, chute 6 is the blind slot being formed on end face, by the way of blind slot, can more easily install and assemble sliding block 2 and elasticity
Element 3, also simplify the difficulty of structure design.
Fig. 7 and Fig. 8 is refer to, the T-shaped structure that the sliding block 2 in the utility model is constituted using block 7 and guide post 8,
Wherein, one end of guide post 8 is connected with block 7, the other end is inserted in chute 6.Additionally, the shape of block 7 can be rectangle or
It is trapezoidal etc., as long as the circulation area of air inlet can be adjusted.
Refer to Fig. 1, the end of one end towards flexible member 3 of guide post 8 and flexible member 3 are by the mode such as abutting
Cooperation is assembled up.For example, in the embodiment shown in fig. 8, can form one on the end face of the other end of guide post 8 is used for
The depression 19 of the small end of flexible member 3 is accommodated, the depression 19 can also be that cone waits it using the rectangle shown in Fig. 8
His shape.By way of depression 19, flexible member 3 can be preferably fixed, it is ensured that it provides elastic force along radial direction.Please join
Fig. 7 is examined, the end face towards the side of annular groove 5 of block 7 is in the arc coordinated with the madial wall of annular groove 5, in order to the inner side of annular groove 5
Wall coordinates, and is conducive to the abrasion for preventing collision from producing, and is also beneficial to reduce noise.
Fig. 4 is refer to, the utility model forms a fixing hole 9 connected with chute 6 on the lateral wall of annular groove 5, more
Especially, the fixing hole 9 can be a through hole, and during installation, at least a portion of flexible member 3 is fixed in fixing hole 9.For
Bigger decrement is provided, preferably using the spring in taper type, it is towards sliding block 2 for the flexible member 3 in the utility model
One end be small end, due to the full-size of the maximum gauge more than fixing hole 9 at big end, therefore big end then can be by interference fit
Mode be fixedly connected with fixing hole 9, for example, big end can protrude from the outside of body 1.In a preferred embodiment, it is
Suitable for larger decrement, the spring diameter of section of flexible member 3 is 0.5mm, spacing 0.5mm, length 10mm, small end are straight
Footpath 2mm, outside diameter 3.5mm.
Wherein, the specification of flexible member 3 can be according to the pass for opening opportunity, unlatching size and running frequency of required air inlet
System is determined and adjusts.Because, under the different running frequency of compressor, the centrifugal force that sliding block 2 can be generated is different.
By adjusting the parameter such as material, step pitch of flexible member 3, the coefficient of elasticity of spring can be changed, so as to obtain different running frequencies
Under amount of spring compression, and then realize control different frequency under slider displacement amount and air inlet aperture.
In the utility model, a buffering cavity can be formed by annular groove 5, be carried out with to entering the refrigerant in annular groove 5
Buffering and separation.In order to discharge the refrigeration oil isolated, the utility model also forms one or more on the lateral wall of annular groove 5
The venthole 10 that (such as 8) connect with annular groove 5, since discharge via oil guard annular groove constitute inside cavity buffer
Refrigeration oil refrigerant.
Annular groove 5 in the utility model changes oil-containing refrigerant by way of runner flows out, will refrigerant in the prior art
The mode that refrigeration oil is flowed directly out, is changed into the buffering cavity constituted by annular groove 5, so that the refrigeration oil in being mixed in refrigerant can be more
Flowed out again after many absorption, thus increased the oily efficiency of gear.
In the illustrated embodiment, venthole 10 is circular port, and in other embodiments (not shown), venthole 10 can also
Can be adjusted according to required exhaust velocity using trapezoidal hole, stepped hole diplodal, and its aperture or number.
For the ease of oil guard is coupled together with the other parts installation in rotor assembly, the utility model is also in ring
The mounting holes 11 of multiple axial directions are formed on the lateral wall of groove 5, so, can by the modes such as rivet formed one it is complete
Rotor assembly.
Fig. 9 and Figure 10 is refer to, the utility model additionally provides a kind of rotor assembly, including above-mentioned oil guard 12.
For example, in the rotor assembly, oil guard 12 is arranged on the end of rotor core 13, and the air inlet 4 of oil guard 12 with
