In the compressor 100 shown in Fig. 1, compressing mechanism is by determining scroll element 150 and moving scroll element 160 forms.More specifically, determining scroll element 150 comprises end plate 154, is formed on the spiral helicine blade 156 of end plate one side and is formed on the relief opening 152 of the substantial middle position of end plate.Moving scroll element 160 comprises end plate 164, be formed on the hub portion 162 of end plate one side and be formed on the spiral helicine blade 166 of end plate opposite side.Be engaged with each other to form betwixt compression chamber C1, C2 and the C3 that a series of volumes are reducing to radially inner side gradually from radial outside determining the helical blade 156 of scroll element 150 and the helical blade 166 of moving scroll element 160.Wherein, the compression chamber C1 of outermost radial outside is in pressure of inspiration(Pi), radially the compression chamber C3 of inner side in exhaust pressure.Middle compression chamber C2 between pressure of inspiration(Pi) and exhaust pressure, thereby be also referred to as middle pressure chamber.
In housing 110, be also provided with the motor 120 being formed by stator 122 and rotor 124.Stator 122 is fixing with respect to described housing 110.Stator 122 can directly be fixed in housing 110 and also can for example be fixed in housing 110 by means of the motor hoop 126 shown in Fig. 1, to form the passage AP passing for for example refrigeration agent of fluid between stator 122 and housing 100.Rotor 124 can in stator 122, rotate and rotor 124 in be combined with running shaft 130 so that running shaft 130 rotates together with rotor 124.Motor 120 drives the compressing mechanism by determining scroll element 150 and moving scroll element 160 and forming as above via running shaft 130.
In housing 110, be further provided with the main bearing seat 140 that supports described compressing mechanism and running shaft 130.Particularly, the downside of moving scroll element 160 is by the thrust plate 142 being arranged in main bearing seat 140, and a part for live axle 130 is supported by the main bearing 144 being arranged in main bearing seat 140.More specifically, main bearing 144 is arranged in the main bearing setting unit 143 of main bearing seat 140.In this example, thrust plate 142 and main bearing seat 140 are designed to independently parts and are then assembled together, but it should be appreciated by those skilled in the art that thrust plate 142 and main bearing seat 140 also can design all-in-one-piece parts.Main bearing seat 140 also comprises diapire 147, thereby main bearing seat 140 is formed as opening up bowl dress member substantially.
Determining scroll element 150 is assemblied on main bearing seat 140 and thinks that compressing mechanism provides described axial elasticity below via sleeve pin 170.More specifically, determine to be provided with multiple smooth faces 158 on the peripheral part of scroll element 150, on main bearing seat 140, be provided with corresponding with these light faces 158 148.Sleeve pin 170 comprises bolt 172 and sleeve 174.Sleeve 174 is arranged in light face 158, and bolt 172 passes sleeve 174 and is screwed in the tapped hole 148 of main bearing seat 140.Like this, determine scroll element 150 and can on sleeve 174, slide to move in predetermined axial range.
One end of live axle 130 is provided with eccentric crank pin 132, is provided with unloading lining 176 and thinks that compressing mechanism provides the radial compliance that will describe below between eccentric crank pin 132 and the hub portion 162 of moving scroll element 160.By the driving of motor 120, moving scroll element 160 will be with respect to determining scroll element 150 translation rotations (, the central axis of moving scroll element 160 is around the central axis rotation of determining scroll element 150, but moving scroll element 160 itself can not rotate around the central axis of self) to realize the compression of fluid.Above-mentioned translation rotation realizes by the cross slip-ring 178 of determining to arrange between scroll element 150 and moving scroll element 160.Be discharged to high pressure side through the fluid of determining after scroll element 150 and 160 compressions of moving scroll element by relief opening 152.In order to prevent that on high-tension side fluid is back to low voltage side via relief opening 152 under specific circumstances, one-way valve or outlet valve V can be set at relief opening 152 places.
In order to realize the compression of fluid, determining needs effective sealing between scroll element 150 and moving scroll element 160.
On the one hand, determine between the top of helical blade 156 of scroll element 150 and the end plate 164 of moving scroll element 160 and the top of the helical blade 166 of moving scroll element 160 and determine to need axial seal between the end plate 154 of scroll element 150.Conventionally, be provided with back pressure cavity CB in a side contrary with helical blade 156 of the end plate 154 of determining scroll element 150.In back pressure cavity CB, be provided with black box S, the axial displacement of black box S is subject to the restriction of dividing plate 116.Thereby back pressure cavity CB is communicated with middle pressure chamber C2 fluid and is formed the power of pressing towards moving scroll element 160 determining scroll element 150 by the axially extended through hole (not shown) forming in end plate 154.Because a side of moving scroll element 160 is supported by thrust plate 142, so utilize pressure in back pressure cavity CB can be effectively will to determine scroll element 150 and moving scroll element 160 forces together.In the time that the pressure in each compression chamber exceedes setting value, thereby the pressure in these compression chambers makes to determine scroll element 150 and moves upward the downforce providing in back pressure cavity CB is provided at making a concerted effort of producing.Now, fluid in compression chamber unloads to low voltage side the top of the helical blade 166 by determine gap between the top of helical blade 156 and the end plate 164 of moving scroll element 160 of scroll element 150 and moving scroll element 160 and the clearance leakage of determining between the end plate 154 of scroll element 150 with realization, thereby provides axial elasticity for compressor.
On the other hand, determine also to need radial seal between the side surface of helical blade 156 of scroll element 150 and the side surface of the helical blade 166 of moving scroll element 160.This radial seal between the two driving force that the centrifugal force in operation process and live axle 130 provide by means of moving scroll element 160 conventionally realizes.Particularly, in operation process, by the driving of motor 120, moving scroll element 160 will, with respect to determining scroll element 150 translation rotations, will produce centrifugal force thereby move scroll element 160.On the other hand, the eccentric crank pin 132 of live axle 130 also can produce and contribute to realize the driving force component of determining scroll element and moving scroll element radial seal in rotary course.The helical blade 166 of moving scroll element 160 will abut on the helical blade 156 of determining scroll element 150 by means of above-mentioned centrifugal force and driving force component, thereby realizes the radial seal between the two.When incompressible material (such as solid impurity, lubricant oil and liquid refrigerant) enters in compression chamber and between helical blade 156 and helical blade 166 time, helical blade 156 and helical blade 166 can temporarily radially be separated from each other to allow foreign matter to pass through, and have therefore prevented that helical blade 156 or 166 from damaging.This ability that can radially separate, for compressor provides radial compliance, has improved the reliability of compressor.
To the lubrication and cooling process of each parts in compressor be described below.In the example of the compressor shown in Fig. 1, store oiling agent in the bottom of compressor housing 110, the liquid level height of oiling agent is for example referred to by OL.For oiling agent being supplied to the parts such as the bearing of compressor, in live axle 130, be formed with roughly along its axially extended oiling agent supply passage OP.Oiling agent supply passage OP can comprise the eccentric opening 134 that is formed on the center hole 136 of live axle 130 lower ends and extends up to eccentric crank pin 132 end faces from center hole 136.The end of center hole 136 is immersed in the oiling agent bottom compressor housing or has otherwise been supplied to oiling agent.In the example described in Fig. 1, for example, in this center hole 136 or feeding lubricating device is set, oil fork 138 near it.In the operation process of compressor, the lubricated agent feeding device in one end of center hole 136 is supplied with oiling agent, and the oiling agent that enters center hole 136 is subject to the effect of centrifugal force and upwards flows and arrive the end face of eccentric crank pin 132 always in being pumped or being thrown to eccentric opening 134 and along eccentric opening 134 in live axle 130 rotary courses.The oiling agent of discharging from the end face of eccentric crank pin 132 flows downward and arrives the recess 146 of main bearing seat 140 along the gap between gap and unloading lining 176 and hub portion 162 between unloading lining 176 and eccentric crank pin 132.Be gathered in a part of oiling agent in recess 146 and flow and flow downward through main bearing 144 and/or the tap hole (not shown) that is formed on main bearing seat, a part of oiling agent stirred and move to by hub portion 162 and/or counterweight CW moving scroll element 160 end plate 164 downside and spread all over the thrust surfaces between moving scroll element 160 and thrust plate 142 along with the translation rotation of moving scroll element 160.In the operation process of compressor, be supplied to oiling agent on the comings and goings parts in compressor and be thrown out of and splash to form drop or mist.These lubricant droplet or mist will be blended in the working fluid (or refrigeration agent) sucking from air input joint 118.These working fluids that are mixed with lubricant droplet are inhaled in the compression chamber of determining between scroll element 150 and moving scroll element 160 to realize lubricated, the sealing and cooling of these scroll element inside subsequently.The fluid that motor 120 can suck by oiling agent with from air input joint 118 the two come cooling.
As described in the background section, the size of oil recycle ratio depends on the size of the amount of the oiling agent being carried as refrigeration agent by working fluid.In the compressor of prior art, the oiling agent being carried in working fluid mainly comprises two-part: first portion is the lubricant droplet sputtering between driven scroll element 160 and thrust plate 142, and second portion is flow downward via main bearing 144 or above-mentioned tap hole from main bearing seat 140 and thrown away by movable parts such as rotors and the lubricant droplet that forms.In the large compressor of refrigerating capacity, this two-part lubricant droplet has formed the major component of large oil recycle ratio.
In order to reduce oil recycle ratio, in the compressor 100 of the first mode of execution of the present invention, further provide following structure.More specifically, be provided with the first lubricant passageway 145 passing through for oiling agent in the bottom of main bearing seat 140.More specifically, as shown in Figure 2, the first lubricant passageway 145 can be formed at least one through hole in the main bearing setting unit 143 of main bearing seat 140, this at least one through hole can be for example along the longitudinal extension of main bearing seat 140.In rotor 124, be provided with the second lubricant passageway 125 passing through for oiling agent.More specifically, as shown in Figure 4, the second lubricant passageway 125 can be formed at least one through hole in rotor 124.Between main bearing seat 140 and rotor 124, be provided with oiling agent gathering-device 180.Oiling agent gathering-device 180 is configured to reception from the oiling agent of the first lubricant passageway 145 of main bearing seat 140 and received oiling agent is supplied in the second lubricant passageway 125 of rotor 124.In a kind of optimal way, oiling agent gathering-device 180 can be constructed to be permeable to rotor 124 rotations.
As shown in Fig. 3 A, 3B and 3C, in the first mode of execution of the present invention, oiling agent gathering-device 180 can be configured to roughly cup part.Simultaneously with reference to Fig. 1, oiling agent gathering-device 180 can comprise the inner circle wall 182 being fixed on running shaft 130, the diapire 184 roughly extending radially outwardly from inner circle wall 182 and from roughly upwardly extending periphery wall 186 of diapire 184.The bottom opening 185 being communicated with the second lubricant passageway 125 fluids of rotor 124 can be set on diapire 184.Cup part can also comprise the roof 188 roughly extending radially inwardly from periphery wall 186.Roof 188 comprises for receiving the open top 189 from the oiling agent of the first lubricant passageway 145 of main bearing seat 140.The diapire 184 of cup part can be arranged to the end of butt rotor 124.In addition, the roof 188 of cup part can be arranged to the lower end of contiguous main bearing seat 140.
In the compressor of as above constructing, in the time of compressor operation, as shown in Figure 1 (in Fig. 1, with filled arrows represent oiling agent flow, represent flowing of working fluid with dotted arrow), the oiling agent flowing out from the oiling agent supply passage OP of running shaft 130 is gathered in the recess 146 of main bearing seat 140.The oiling agent being gathered in recess 146 flows out and enters oiling agent gathering-device 180 from open top 189 from the first lubricant passageway 145.Because oiling agent gathering-device 180 is along with running shaft 130 rotates together, so the oiling agent being gathered in oiling agent gathering-device 180 can form as shown in Figure 1 the roughly pasta P of parabolic shape.The roof 188 of oiling agent gathering-device 180 contributes to prevent that oiling agent from throwing away oiling agent gathering-device 180.Subsequently, the oiling agent in oiling agent gathering-device 180 flows in the second lubricant passageway 125 of rotor 124 and finally turns back to the oil sump of housing 110 bottoms via bottom opening 185.In this process, this part oiling agent (being referred to as first portion's oiling agent below) can mix with the fluid sucking from air input joint 118 hardly, therefore also can contribute to hardly the increase of oil recycle ratio.
On the other hand, as in the compressor of prior art, be gathered in a part of oiling agent in recess 146 stirred and move to by hub portion 162 and/or counterweight CW moving scroll element 160 end plate 164 downside and spread all over the thrust surfaces between moving scroll element 160 and thrust plate 142 along with the translation rotation of moving scroll element 160, be thrown out of subsequently and form lubricant droplet.The lubricated overwhelming majority that contribute and form oil recycle ratio of this part oiling agent (being referred to as second portion oiling agent below) to compressing mechanism and miscellaneous part.
Compared with prior art, owing to having got rid of the contribution of first portion's oiling agent to oil recycle ratio, so greatly reduce oil recycle ratio.Meanwhile, the working fluid that the stator 122 of motor 120 can be relatively low by the temperature sucking from air input joint 118 comes cooling, so the efficiency of motor 120 also can not reduce.
Inventor is to having carried out contrast test according to the compressor of the compressor of first embodiment of the invention and prior art, and result is as shown in the table:
| Oil recycle ratio under normal oil level | Oil recycle ratio under high oil level | |
| The compressor of prior art | 2.29% | 8.44% |
| According to compressor of the present invention | 1.28% | 4.36% |
In above-mentioned test, according to being provided with the first lubricant passageway 145, the second lubricant passageway 125 and oiling agent gathering-device 180 in compressor of the present invention, other structures are identical with compressor of the prior art.Can find out, though the oil level of the oiling agent in compressor in normal oil level or in high oil level, the oil recycle ratio of compressor of the present invention can both significantly reduce.
Particularly, the position of air input joint 118 can be determined according to the cooling effect that will realize.For example, in the time need to increasing the cooling effect of motor 120, air input joint 118 compressor longitudinally on position can be arranged to the lower end near stator 122.Otherwise, in the time need to reducing the cooling effect of motor 120, air input joint 118 compressor longitudinally on position can be arranged to middle part or the upper end near stator 122.
For mixing of the fluid that prevents from better sucking from air input joint 118 and above-mentioned first portion oiling agent, can motor cover 190 be set in the lower end of stator 122.More specifically, motor cover 190 can comprise diapire 192 and from roughly upwardly extending periphery wall 194 of diapire 192.Periphery wall 194 can be fixed in the stator core of stator 122.On the diapire 194 of motor cover 190, be formed with the opening 193 passing for running shaft 130.On the diapire 192 of motor cover 190, can further be formed with the opening 195 passing through for oiling agent.Owing to being provided with motor cover 190, further reduce the chance that the oiling agent of discharging from the second lubricant passageway 125 of rotor 124 mixes with working fluid.
Further, the diapire 192 of motor cover 190 can be arranged to close on the liquid level OL of the oiling agent of storing in compressor or be positioned under liquid level OL.Like this, can substantially completely cut off mixing of working fluid and first portion's oiling agent.Thereby can greatly reduce oil recycle ratio.
It should be appreciated by those skilled in the art that the present invention is not limited to the example shown in Fig. 1-Fig. 5 B, but can carry out various modification.
For example, can omit the motor cover 190 in compressor.In this case, the bottom of stator 122 can be arranged to close on the liquid level OL of the oiling agent of storing in compressor or be positioned under liquid level OL, further to reduce oil recycle ratio.
For example, the roof 188 of oiling agent gathering-device 180 can omit.In this case, the height design of the periphery wall of oiling agent gathering-device 180 186 can be become the oiling agent in oiling agent gathering-device can not overflowed from periphery wall 186.
For example, the bottom opening 185 on the diapire 184 of oiling agent gathering-device 180 is not limited to the circular hole shown in Fig. 3 A and size, but can be various shapes and size.
For example, the quantity of the second lubricant passageway 125 in rotor 124 is not limited to one, but can be multiple.
For example, the diapire 184 of oiling agent gathering-device 180 can be via extra liner etc. the top butt with rotor 124.
For example, oiling agent gathering-device can also be fixed on rotor 124.For example, in the second mode of execution as shown in Figure 6, oiling agent gathering-device 180A comprises the roughly body 182A of tubular, and the first end of body 182A is fixed on rotor 124.The second end of body 182A is formed with the roof 184A roughly extending radially inwardly.Roof 184A can comprise for receiving the open top 189A from the oiling agent of the first lubricant passageway 145 of main bearing seat 140.The roof 184A of oiling agent gathering-device 180A can be arranged to the lower end of contiguous main bearing seat 140.In this structure, the oiling agent flowing out from the first lubricant passageway 145 of main bearing seat 140 can be gathered in the space being formed by the top of oiling agent gathering-device 180A and rotor 124 and flow in the second lubricant passageway 125 of rotor 124.Other structures of the second mode of execution are basic identical with the first mode of execution, do not repeat them here.
For example, oiling agent gathering-device can also be shown in Fig. 1 by the groove 127(being formed on rotor 124 ends) form.In this case, groove 127 can be communicated with the second lubricant passageway 125 fluids by variety of way.
In the above-described embodiment, the first lubricant passageway 145 in main bearing seat 140 is configured at least one axial hole being formed in main bearing setting unit 143, but the present invention is not limited thereto.For example, as shown in Fig. 7 A and 7B, can be with respect to the fore-and-aft tilt of main bearing seat 140 to make the opening of at least one through hole be positioned at the side of main bearing setting unit 143 or to be positioned at the side of main bearing setting unit 143 and the intersection location place of the diapire of main bearing seat 147 as at least one through hole of the first lubricant passageway 145.In this structure, the position of the entrance of the first lubricant passageway 145 is minimized, thereby the oiling agent being gathered in main bearing seat 140 can more easily flow into oiling agent gathering-device 180 or 180A via the first lubricant passageway 145.Again for example, as shown in Fig. 8 A and 8B, tubular part 149 can be set at least one through hole, and tubular part 149 can extend in oiling agent gathering-device 180 or 180A.Adopt this structure, can further prevent the tubular part 149 more accurately from the first lubricant passageway 145() flow out oiling agent because the rotation of rotor 124 is splashed.
