Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below in conjunction with accompanying drawing detailed description according to the motor 10 of the embodiment of the present invention and compressor 100.Wherein compressor 100 can be polytype, is described below for compressor 100 for rotary compressor.
Shown in Figure 12, the compressor 100 according to the embodiment of the present invention comprises the parts such as housing 20, the pump housing and motor 10.Specifically, motor 10 and the pump housing are located in the housing 20 of compressor 100.The housing 20 of compressor 100 is provided with blast pipe 30, and the side of the contiguous motor 10 of blast pipe 30 is arranged.
Motor 10 comprises stator 14, rotor 11 and oil baffle 12.Stator 14 is located at the periphery of rotor 11, stator 14 and rotor 11 spaced apart formation rotor gap 16.Rotor 11 is provided with rotor through hole 111.On the upper surface that oil baffle 12 is located at rotor 11 and/or lower surface, that is, on the upper surface that oil baffle 12 can be located at rotor 11 or lower surface, or the upper surface of rotor 11 and lower surface are equipped with oil baffle 12.
Oil baffle 12 comprises base plate 121 and side plate 122, and side plate 122 is around in the edge, periphery of base plate 121.With reference to shown in Fig. 3 to Figure 12, base plate 121 is provided with single through hole 123, and that is, base plate 121 is provided with a through hole 123.The upper surface of rotor 11 and lower surface are respectively equipped with balance weight 15.The balance weight 15 being positioned at the same side with oil baffle 12 is placed on the base plate 121 of this oil baffle 12.
Oil baffle 12 and balance weight 15 are all fixed on rotor 11 by fixture.Wherein, fixture is connected with rotor 11 with balance weight 15 through oil baffle 12.Alternatively, fixture can be rivet.Namely oil baffle 12 and rotor stop plate 13 can be riveted together with rotor 11, are connected firmly, not easily loosen, and ensure that compressor 100 reliability of operation.
Compressor 100 operationally, most of cold media gas of discharging from the pump housing of compressor 100 through rotor gap 16, rotor through hole 111.If do not have oil baffle 12, cold media gas can be flowed directly to blast pipe 30 place and discharge.As shown in Figure 1, when motor 10 is provided with oil baffle 12, cold media gas can collide with oil baffle 12 behind rotor gap 16 and rotor through hole 111, thus the flow velocity of cold media gas and direction are changed, and changes direction as shown by the arrows in Figure 1.
The cold media gas changed behind direction is then upwards discharged on the wall on housing 20 top, and continue to collide with the wall on housing 20 top, flow velocity is reduced again, thus the little oil droplet be blended in cold media gas is separated out from cold media gas, and flow back in the oil sump of compressor 100 along the wall of housing 20, effectively prevent cold media gas and directly discharge two from the blast pipe 30 of housing 20 and cause the oil droplet be blended in cold media gas directly to be discharged from blast pipe 30.
Thus, according to the compressor 100 of the embodiment of the present invention, refrigeration oil can control in compressor 100 by the oil baffle 12 arranged in the motor 10 of compressor 100, prevent refrigeration oil from leaking outside, what effectively reduce compressor 100 tells oil mass, alleviate the phenomenon of compressor 100 oil starvation, extend the useful life of compressor 100, improve the reliability of compressor 100; Avoid refrigeration oil enters in refrigerating system with refrigerant simultaneously, and the performance of whole system can not be affected.
As depicted in figs. 1 and 2, motor 10 also can comprise rotor stop plate 13 further, on the upper surface that rotor stop plate 13 is located at rotor 11 and/or lower surface.That is, on the upper surface that rotor 11 can be located at rotor 11 or lower surface, or the upper surface of rotor 11 and lower surface are equipped with rotor stop plate 13.And oil baffle 12 can be located between the corresponding end-faces of oil baffle 12 and rotor 11 at the rotor stop plate 13 of the same side.Such as, as shown in Figure 2, the upper surface of rotor 11 is provided with an oil baffle 12 and rotor stop plate 13, and rotor stop plate 13 is between oil baffle 12 and the upper surface of rotor 11.This kind of structure can make oil baffle 12 more firm with coordinating of rotor 11, effectively prevent leaking outside of oil further.
It should be noted that, rotor stop plate 13 is not necessary parts, and the base plate 121 of oil baffle 12 can substitute rotor stop plate 13, makes the upper surface of rotor 11 can only be arranged oil baffle 12, can simplify the structure of compressor 100 thus.Wherein, the rotor stop plate 13 whether cancelled on rotor 11 upper surface is determined by actual needs.
When comprising oil baffle 12 and balance weight 15 according to the motor 10 of the embodiment of the present invention, oil baffle 12 and balance weight 15 can form the oily assembly of gear, when comprising oil baffle 12, balance weight 15 and rotor stop plate 13 according to the motor 10 of the embodiment of the present invention, oil baffle 12, balance weight 15 and rotor stop plate 13 can form the oily assembly of gear.Refrigeration oil can control, in compressor 100, to prevent refrigeration oil from leaking outside by this gear oil assembly, and what effectively reduce compressor 100 tells oil mass, alleviates the phenomenon of compressor 100 oil starvation, extends the useful life of compressor 100, improves the reliability of compressor 100; Avoid refrigeration oil enters in refrigerating system with refrigerant simultaneously, and the performance of whole system can not be affected.Wherein, balance weight 15 can make gear oil component integration more firm, improves service behaviour.
With reference to shown in Fig. 3 to Figure 12, base plate 121 can be formed as circular.Circular base plate 121 is convenient to make, and can adapt with the end face of rotor 11, reaches the effect preventing refrigeration oil from leaking outside preferably.Side plate 122 can be arranged perpendicular to base plate 121.Thus, leaking outside of oil can effectively be prevented.
Base plate 121 has single through hole 123, through hole 123 is formed as irregularly-shaped hole, the week of this irregularly-shaped hole is along having outer tongue 124, when assembling motor 10, rotating shaft can penetrate the middle part of irregularly-shaped hole, simultaneously the outer tongue 124 of irregularly-shaped hole can be used for penetrating fixture and uses, and base plate 121 can be fitted the end face of rotor 11 or rotor stop plate 13.Thus, oil baffle 12 can match with balance weight 15 and rotor 11 preferably, reaches the effect preventing oil from leaking outside.Wherein, the quantity of outer tongue 124 and shape can be arranged as required.
Be understandable that, the shape of through hole 123 is not limited only to described above, also can be other shapes.Such as, through hole 123 can be formed as other suitable shapes such as circular or rectangle.
Advantageously, base plate 121 and side plate 122 can be formed in one part.Namely oil baffle 12 forms as one shaping structure.This kind of structure easily manufactures and structural stability is good.Certainly, base plate 121 and side plate 122 also can for be processed into shaped piece separately.Namely base plate 121 and side plate 122 can individually manufacture shaping, and then base plate 121 and side plate 122 are joined together to form oil baffle 12.Wherein, base plate 121 and side plate 122 adopt the mode of welding to be connected, and this kind of connected mode connects reliable, is convenient to processing.
