Abstract
The invention discloses a scroll compressor, relating to the technical field of fluid machinery. The scroll compressor comprises a balancing component installed on a driving shaft, wherein the balancing component is provided with a shaft sleeve and a balancing weight installed outside the shaft sleeve, and at least part of the binding surface between the outer side of the shaft sleeve and the balancing weight is the plane for preventing the relative rotation between the shaft sleeve and the balancing weight. Compared with the prior art, the invention can solve the problem that low working reliability of the balancing component can damage the machine.
Description
Technical field
The present invention relates to the fluid machinery technical field, 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 fuselage often, drives it and rotates with respect to fixed scroll and orbiter is live axle by bias, in order to reduce the rotation of this eccentric drive, needs to be set with balanced component on 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 both pin in relative rotation.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, the phenomenon that is even cut up causes scroll compressor fault and destruction to scrap.
Summary of the invention
The purpose of this invention is to provide a kind of scroll compressor, 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 used in the present invention is: this scroll compressor comprises the balanced component that is contained on live axle, described balanced component has axle sleeve and is contained in the outer equilibrium block of this axle sleeve, and the mating face of the described axle sleeve outside and described equilibrium block has a part at least for preventing both plane in relative rotation.
In 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 present invention compared with prior art has following beneficial effect: because outside axle sleeve and the mating face of equilibrium block has a part at least for preventing both plane in relative rotation, therefore the larger speed change in the time of can fundamentally having solved due 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 structural representation of the embodiment of the present invention.
Fig. 2 is the plan view of the balanced component of the embodiment of the present invention.
Fig. 3 is left view in Fig. 2.
Embodiment
The invention will be further described 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 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, as shown in Figure 2 and Figure 3.Because the mating face of axle sleeve 4 outsides and equilibrium block 6 is to prevent both six six prismatic surfaces that the plane surrounds in relative rotation, therefore cause relatively rotating between equilibrium block 6 and axle sleeve 4 in the time of can fundamentally having solved due 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 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 mating face of the described axle sleeve outside and described equilibrium block has a part at least for preventing both plane in relative rotation.
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.
