Embodiment 1
As shown in figure 1, the present embodiment provides a kind of rotary compressor, comprising: body 1；Bent axle 2, has eccentric part 21, leads to
Cross the clutch shaft bearing 3 being set in described eccentric part 21 both sides and second bearing 4 is installed in rotation in described body 1；Pass through
Described eccentric part 21 drives the cylinder 5 being arranged in described body to be compressed air work；Described second bearing 4 and described song
It is provided with axial limit structure between the corresponding coupling part of axle 2, be used for making to protect between described eccentric part 21 and described second bearing 4
Hold axial gap.
Pass through described position limiting structure, described bent axle 2 can be lifted certain altitude, thus prevent described eccentric part 21 with
Coming in contact between described second bearing 4, thus avoiding that friction generation noise occurs therebetween, causing compressor power consumption to increase
Greatly.
As shown in figure 1, rotary compressor is vertically placed described in the present embodiment, the rotation axiss of bent axle 2 are vertically arranged, the
Two bearings 4 are located at the lower section of described eccentric part 21, now because the effect of axial limit structure is so that eccentric part 21 acts on the
Two bearing 4 top certain distance, it is to avoid rub therebetween, the space vertically placing occupancy is less, is conducive to device
Miniaturization.
In the present embodiment, as shown in Figures 2 and 3, described axial limit structure includes being arranged on the lower end of described bent axle 2
Bearing-surface 22 directed downwardly and be arranged on the described second bearing 4 described bearing-surface 22 for supporting described bent axle 2 upward
Support face 41.
Described supporting surface 41 is offseted with described bearing-surface 22, thus bent axle 2 is promoted to certain altitude, and then prevents bent axle
2 eccentric parts 21 are contacted with the upper surface of second bearing 4.
Specifically, when described rotary compressor works, described bent axle 2 rotates under the drive of electric machine assembly 11,
The eccentric part 21 of bent axle 2 is connected with roller 13, and roller 13 rotates in cylinder 5, and the coolant in liquor separator 12 flows in cylinder 5,
Coolant in cylinder 5 is compressed and discharges by the rotation of roller 13.Now described bearing-surface 22 will be in described supporting surface
Rotated on 41, due to contact area very little therebetween, therefore can effectively be reduced frictional force therebetween.
Specifically, as shown in Fig. 2 the lower end of described bent axle 2 forms necking part；The transition face of described necking part perpendicular to
The pivot center of described bent axle 2, the transition face of described necking part constitutes described bearing-surface 22.Described supporting surface 41 acts against described
The lower section of bearing-surface 22, so that it is guaranteed that described bent axle 2 keeps vertical.
In the present embodiment, as shown in figure 3, forming annular retaining groove 6 inside described second bearing 4, a circlip type bearing
Back-up ring 7 is connected in described annular retaining groove 6, and described end ring side upward constitutes described supporting surface 41.
Because annular retaining groove 6 is placed on the medial surface of described second bearing 4, therefore iff adopting closed circle,
Then it is difficult to position limiting structure is attached in annular groove, and adopts circlip type end ring 7, its own is provided with opening, Ke Yitong
Cross the size that external force adjusts opening circle diameter, and then so that circlip type end ring 7 is stably placed inside annular retaining groove 6.
Certainly, described circlip type end ring can also be replaced using other back-up rings in the present embodiment, as long as described axle
Hold back-up ring and be provided with opening, so can adjust end ring by external force make it be adjacent to described annular groove.
In the present embodiment, as shown in figure 1, the bottom of described body 1 is provided with oil pocket 8, described second bearing 4 and described bent axle
2 lower end is immersed in described oil pocket 8.
Because described second bearing 4 immerses in oil pocket 8 so that being moistened between described supporting surface 41 and described bearing-surface 22
Sliding, friction therebetween can be reduced, and be prevented from noise generation.
In the present embodiment, as shown in figure 3, described axial limit structure also includes being molded over the annular of described bent axle 2 lower end
Stopper slot 23, a circlip type bent axle back-up ring 10 is connected in described stopper slot and is located at described second bearing 4 outer face side,
For keeping, between described eccentric part 21 and described clutch shaft bearing 3, there is axial gap.
When described bent axle 2 is offset up by external force, bent axle 2 back-up ring can be connected with the outer face of second bearing 4
Touch, because bent axle 2 back-up ring itself and bent axle 2 are connected as a single entity, that therefore can pass through the bent axle 2 back-up ring described bent axle 2 of restriction enters one
The motion upwards of step, and then prevent from rubbing between the upper surface of described eccentric part 21 and the lower surface of described clutch shaft bearing 3.
Specifically, described bent axle 2 back-up ring and the distance between described second bearing 4 outer face h1Less than described eccentric part 21
With the distance between described clutch shaft bearing 3 h2.
Due to h1<h2, therefore when bent axle 2 back-up ring abuts in the outer face of described second bearing 4, described eccentric part 21
Still there is between upper surface and clutch shaft bearing 3 gap, and then prevent the upper surface of described eccentric part 21 and described clutch shaft bearing 3
Rub between lower surface.
Embodiment 2
On the basis of above-described embodiment 1, described second bearing 4 replaces with lower inside and forms radially contracting the present embodiment
Fraction, described radial direction reduces the pivot center perpendicular to described bent axle 2 for the transition face of part, and described radial direction reduces the mistake of part
Face of crossing constitutes described supporting surface 41.Second bearing 4 radially-inwardly shrinks formation supporting surface 41, and described supporting surface 41 supports bent axle 2
Bearing-surface 22, so that described bent axle 2 is vertically rotated on described supporting surface 41, because contact area therebetween is less, because
This frictional force very little producing, can be effectively prevented the noise that friction produces.
As disposable embodiment, the present embodiment rotary compressor described in above-described embodiment 1 or embodiment 2 is replaced
For horizontal positioned, due to described axial limit structure so that eccentric part 21 and second bearing 4 maintain between first in the horizontal direction
Gap, thus efficiently avoid rub therebetween.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.Right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Change among still in the protection domain of the invention.
