Abstract
The utility model discloses a scroll compressor, relating to the technical field of fluid machinery. The scroll compressor comprises a balance assembly installed on a driving shaft, wherein the balance assembly comprises a shaft sleeve and a balance weight installed outside the shaft sleeve; and at least part of the joint face of the outside of the shaft sleeve and the balance weight is a plane preventing the shaft sleeve and the balance weight from rotating relatively. Compared with the prior art, the scroll compressor has the beneficial effect that the problem that the balance assembly in the scroll compressor works unreliably, which can cause machine damage can be solved.
Description
Technical field
The utility model relates to the fluid machinery technical field, and especially a kind of live axle of its orbiter is equipped with the scroll compressor of balanced component.
Background technique
The core component of scroll compressor includes orbiter and fixed scroll, during this two scroll relative movement, the movement at the vortex wall engagement position by these two scroll is dwindled the volume that is enclosed in the gas medium in these two scroll and is realized compression, and at last will be compressed the gas medium discharge.Its fixed scroll of the scroll compressor of this structure is fixed on the fuselage often, drives it and rotates with respect to fixed scroll and orbiter is live axle by off-centre, in order to reduce the rotation of this eccentric drive, needs to be set with balanced component on the live axle.In the prior art, this balanced component includes axle sleeve and is sleeved on the outer equilibrium block of this axle sleeve, in order to prevent equilibrium block with respect to the rotation of axle sleeve, is equipped with between axle sleeve and equilibrium block and prevents the two in relative rotation pin.When the balanced component of this structure occurred larger acceleration change at the live axle that runs up in running, this pin can be subject to a very large shearing force.The loosening of pin just appearred in the scroll compressor of existing this structure after work a period of time, even the phenomenon that is cut up, and caused scroll compressor fault and destruction to scrap.
The model utility content
The purpose of this utility model provides a kind of scroll compressor, and the balanced component work that this scroll compressor can solve in it is unreliable, the problem that can cause machine to destroy.
In order to address the above problem, the technical solution adopted in the utility model is: this scroll compressor comprises the balanced component that is contained on the live axle, described balanced component has axle sleeve and is contained in the outer equilibrium block of this axle sleeve, and the described axle sleeve outside has a part at least for preventing the two in relative rotation plane with the mating face of described equilibrium block.
In the above-mentioned scroll compressor technological scheme, can also be more specifically: the mating face of the described axle sleeve outside and described equilibrium block be the outer side surface of the prism that surrounded by a plurality of described planes.Described prism generally is adopted as six prisms.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: because the mating face of the axle sleeve outside and equilibrium block has a part at least for preventing the two in relative rotation plane, therefore the larger speed change in the time of can fundamentally having solved owing to the balanced component High Rotation Speed causes, and prevents the loosening problem of being cut off of the pin that rotates.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the plan view of the utility model embodiment's balanced component.
Fig. 3 is left view among Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Scroll compressor as shown in Figure 1, it fixedly is equipped with fixed scroll 1 in casing, fixed scroll 1 is by the vortex wall engagement of the vortex wall on it and orbiter 2, the needle roller row 3 of needle bearing are housed in the bearing hole of orbiter 2 lower end surface as shown in Figure 1, be set with the axle sleeve 4 of balanced component in the needle roller row 3, the eccentric mechanism of live axle 5 is housed in the through hole of axle sleeve 4, the outer side surface of axle sleeve 4 in underpart shown in Figure 1 is six prismatic surfaces that surrounded by six planes, this six prismatic surface engages with the endoporus of six prismatic surfaces of equilibrium block 6, such as Fig. 2, shown in Figure 3.Because the mating face of axle sleeve 4 outsides and equilibrium block 6 is to prevent the two in relative rotation six six prismatic surface that the plane surrounds, therefore cause relatively rotating between equilibrium block 6 and the axle sleeve 4 in the time of can fundamentally having solved owing to the high speed-changing rotation of balanced component, thereby solve up hill and dale the insecure problem of balanced component work.
Claims (3)
1. scroll compressor, comprise the balanced component that is contained on the live axle, described balanced component has axle sleeve and is contained in the outer equilibrium block of this axle sleeve, it is characterized in that: the described axle sleeve outside has a part at least for preventing the two in relative rotation plane with the mating face of described equilibrium block.
2. scroll compressor according to claim 1 is characterized in that: the mating face of the described axle sleeve outside and described equilibrium block is the outer side surface of the prism that surrounded by a plurality of described planes.
