Abstract
The utility model discloses a kind of loss of weight roller and compressor pump and air conditioner, the cylinder tubular of roller, the roller inner wall is provided with plural ring annular groove.The utility model in roller inner wall by opening annular groove automatic, the equivalent wall thickness reduction, and meet seal request that mitigates roller.
Description
Technical field
The utility model is related to Compressor Technology field more particularly to a kind of loss of weight rollers and compressor pump and air-conditioning
Device.
Background technology
The operation principle of spinning rollers compressor is roller to be driven to be eccentrically rotated in cylinder by bent axle to carry out air
Compression.Same cylinder can correspond to a series of discharge capacities, and different displacements need to only change roller outer diameter realization.Fig. 1 is the sectional view of roller,
According to compressor displacement theoretical calculation formula it is found that same air cylinder structure, the smaller gap needed between roller and cylinder of discharge capacity
Smaller, so roller outer diameter D, wall thickness h increase, the weight of roller is consequently increased.In compressor operation, because of roller certainly
Increasing idle work that its rotation is consumed again can be bigger.Obviously this is unfavorable for improving compressor efficiency.To reduce roller
The wall thickness h of roller need to be thinned in the idle work of rotation, often directly using the method for increase roller internal diameter d.Increase roller internal diameter d,
It is feasible when coping with small displacement, but for huge discharge when both needs the gap increased between roller and cylinder to subtract outer diameter D
It is small, and increase roller internal diameter d directly makes roller wall thickness h too thin again, rigidity not enough causes deformation to be not achieved when so that the roller is worked
Seal request.
Therefore, how to reduce roller in the case where meeting seal request and flog a dead horse is that industry technology urgently to be resolved hurrily is asked
Topic.
Utility model content
In order to solve drawbacks described above in the prior art, the utility model proposes a kind of loss of weight roller and compressor pumps
Body and air conditioner.
The technical solution adopted in the utility model is a kind of loss of weight roller, the cylinder tubular of roller, and roller inner wall is provided with
Plural ring annular groove.
Further, it annular groove uniform intervals and is arranged in parallel.
Further, the side of annular groove is plane or inner concave arc surface.
Further, roller inner wall is provided with four annular grooves.
The utility model also proposed a kind of compressor pump, including：It is provided with the bent axle of off-centre operation, is sleeved on the song
The roller of eccentric shaft circle periphery, the cylinder for being set in roller periphery, upper flange, the set for being set on bent axle and being bonded cylinder top surface
It is located at the lower flange that cylinder bottom surface is bonded on bent axle；
Roller inner wall is provided with plural ring annular groove.
Further, upper flange, lower flange, cylinder are integrally fixed by screw.
The utility model proposes a kind of air conditioner according to the above-mentioned compressor pump housing, including compressor pump.
Compared with prior art, the utility model mitigates roller weight by opening annular groove in the inner wall of roller, so as to subtract
Few roller flogs a dead horse, and do not influence the effective thickness of roller, and meet seal request.
Description of the drawings
The utility model is described in detail with reference to embodiment and attached drawing, wherein：
Fig. 1 is the sectional view of roller in the prior art；
Fig. 2 is the sectional view of roller in the utility model；
Fig. 3 is the sectional view of another embodiment of roller in the utility model；
Fig. 4 is the explosive view of compressor pump in the utility model.
Specific embodiment
As shown in Figure 2 and Figure 3, the utility model proposes a kind of loss of weight roller, roller 1 is cylindrical barrel, and both ends of the surface are parallel
And with axially vertical, it is evenly spaced to be provided with four circles on the roller inner wall between two chamferings for inner wall and both ends of the surface junction chamfering
Annular groove 11, annular groove 11 are set on roller radially and are mutually parallel in a ring.Excess stock is removed by opening annular groove 11, not
In the case of changing 1 effective internal diameter of roller, equivalent wall thickness reduction so as to mitigate the dead weight of roller, reduces roller and is using process
The middle idle work generated by rotation.
Wherein, annular groove 11 is also used as oil storage tank when roller 1 is rotated using inner wall as contact surface, ensures in roller
The lubricating status of wall, and the side of annular groove forms plane or inner concave arc surface according to different cutter shapes in process,
All in the scope of protection of the utility model.
As shown in figure 4, the utility model also proposes compressor pump made of a kind of above-mentioned loss of weight roller of use, including,
Bent axle 2, bent axle 2 are the cylinder of strip, and middle part is justified with crankshaft eccentric, and 2 axis of bent axle can be surrounded in 2 rotation in an axial direction of bent axle
The heart does eccentric motion, and crankshaft eccentric circle periphery bushing has the roller 1 with annular groove 11, the band for making roller 1 that can justify in crankshaft eccentric
It moves in a circle under dynamic, 1 periphery of roller is arranged with cylinder, and roller is made to be located in the cavity of cylinder 3, and the cavity volume of cylinder 3 is
Roller 1 moves in a circle the range of rotation using 2 axle center of bent axle as the center of circle, and 3 top of cylinder, which is equipped with, to be sleeved on bent axle 2 and be bonded cylinder
The upper flange 4 of top surface, the top for making the cavity of cylinder 3 is closed in addition into and out of stomata, and the lower section of cylinder 3, which is equipped with, is sleeved on bent axle 2
The lower flange 5 of upper enclosed cylinder bottom surface, upper flange 4, cylinder 3, lower flange 5 are provided with position opposing through-bores around 2 axle center of bent axle,
It is integrally fixed by screw.The roller 1 of annular groove is opened by using inner wall, is meeting seal request, is reducing 1 institute of roller
The idle work done improves efficiency.
Another embodiment of the utility model also proposed a kind of air conditioner, mainly include the above-mentioned compressor pump housing.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
