It is fixed together with internal rotor 81.
Connect due to being added in rotary compressor provided in an embodiment of the present invention in the upside of motor 5 with the upper end of bent axle 1
The gear pump 8 connect, the footstock 3 and partition plate 2 that are connected with gear pump 8.Therefore during its normal operation, the rotor 51 of motor 5 is with dynamic crankshaft 1
Rotate, and then bent axle 1 drives the internal rotor 81 of gear pump 8 to rotate, the oil sucting cavity volume of 81 rotation process middle gear of internal rotor pump 8
Gradually increase and form parital vacuum, the air pressure in oil sucting cavity is relatively low and it is connected with the oil inlet 32 of footstock 3, therefore the upside of footstock 3
I.e. the refrigeration oil 7 of the upside of motor 5 accumulation is inhaled into the oil sucting cavity of gear pump 8 due to the effect of air pressure, so internal rotor 81 after
The continuous refrigeration oil 7 that rotates is taken to oil-discharging cavity, and the volume of oil-discharging cavity, which is gradually reduced, extrudes its internal refrigeration oil 7, due to oil extraction
Chamber is connected with the oiler of the oily passage 11 of bent axle 1, therefore internal rotor 81 rotates the refrigeration oil 7 in oil-discharging cavity draining into oily passage 11
Interior, internal rotor 81 persistently rotates and realizes continuous oil suction oil extraction.Can be along it after in the oily passage 11 of the entrance bent axle 1 of refrigeration oil 7
Circulation downwards, realizes that more refrigeration oils 7 are back to 5 lower space of motor and are back to rotary compression motor spindle with this.
Refrigeration oil 7 is set to be back to the logical of the downside of motor 5 from the foregoing, it will be observed that rotary compressor provided by the invention adds
The oil inlet 32 that road, i.e. refrigeration oil 7 on the upside of motor 5 can be inhaled into footstock 3 enters gear pump 8, and then flow to oily passage 11
In and flow back along oily passage 11.In this way, by gear pump 8 and the oily passage 11 being arranged on bent axle, by the cold of motor top
Frozen oil draws back compression motor spindle oil sump, and motor speed is faster, and oil return effect becomes apparent from, and substantially reduces the friction of 6 component of the pump housing
Power, reduces the abrasion of the rotary compressor, ensure that compressor lubrication reliability.
It should be noted that the oil inlet of footstock 3 should be as far as possible low, to ensure that more refrigeration oils can flow into footstock
In oil inlet and then enter in gear pump 8.In order to interfere stator of the footstock 3 when mounted not with motor, the downside of footstock 3 is straight
Footpath should be not more than the outside diameter of rotor.
Wherein, holding tank 34 can be stepped groove, and a part for partition plate 2 is connected with cell wall, and another part is located at gear pump 8
Downside, realizes that partition plate 2 closes the downside of oil sucting cavity and oil-discharging cavity with this.
Preferably, the edge of footstock 3 can be fixedly connected with 4 inner wall of shell of the rotary compressor, realize footstock 3
It is fixed, so only need the center of footstock 3 to be connected with gear pump 8 and partition plate 2, the edge and shell 4 of footstock 3 can weld,
It is clamped or is bolted.Footstock 3 is generally circular, to be connected with the inner wall of shell 4.For the ease of footstock 3 and gear
Pump 8 and partition plate 2 connect, and the downside center of footstock 3 can set downwardly convex boss, and receiving is so opened up on boss
Groove 34.Footstock 3 can be metal material.Certainly, footstock 3 can also be fixed by the bracket in the shell 4 of rotary compressor
Portion, is not limited thereto.
Further, the hollow hole 33 of multiple perforations can also be offered on footstock 3, so accumulates in the upside of footstock 3
Refrigeration oil 7 not only can may also pass through the hollow hole 33 on footstock 3 by the circulation downwards of oily passage 11 and flow to inside motor 5,
And then by 5 internal reflux of motor to the pump housing 6, further increasing the amount for the refrigeration oil 7 being back in the pump housing 6.Wherein, engrave
The shape of emptying aperture 33 can be arc.Specifically, two layers of hollow hole 33 along the radial direction of footstock 3, two layers of hollow out can be set
Hole 33 is arranged concentrically, every layer of hollow hole 33 for including four arcs.Certainly, the shape of hollow hole 33 can also be circular, square
Deng being not limited thereto.
Smoothly it is flow in oily passage 11 for the ease of the refrigeration oil 7 in oil-discharging cavity in gear pump 8, the inside of footstock 3 is also
The flowing lumen 31 connected with the oiler of oily passage 11 can be offered, and the refrigeration oil 7 in gear pump 8 can be squeezed and become a mandarin
In cavity 31.I.e. flowing lumen 31 is connected with the oiler of oily passage 11 and the oil-discharging cavity of gear pump 8 at the same time, the oily quilt in oil-discharging cavity
Squeeze into flowing lumen 31 and then flow in oil inlet passage 11.So that partial freeze oil 7 is accumulated in flowing lumen 31, it is cold to ensure
In the stream oil inlet passage 11 that frozen oil 7 can continue.Flowing lumen 31 can certainly be not provided with, directly by the oiler of oily passage 11
Connected with oil-discharging cavity.
In order to further optimize above-mentioned technical proposal, wherein the oil outlet of oily passage 11 can be with the lower space of motor 5
Connection, and the oil outlet of oily passage 11 is located at the top of 6 upper flange of the pump housing.So can from the refrigeration oil 7 of oily passage 11 outflow
Motor spindle oil sump is compressed to return, ensures compressor lubrication reliability.
It is possible to further open up fluted 511 in the downside of the rotor 51 of motor 5, oily passage 11 include vertical section and
Horizontal segment, and its vertical section is set along the axis of bent axle 1, its horizontal segment is set along perpendicular to the direction of 1 axis of bent axle, oil
The oil outlet of passage 11 is the end of horizontal segment, and the oil outlet of oily passage 11 is located in groove 511, and is opened in bent axle 1
Side wall on.Its internal refrigeration oil 7 can be thrown away and got rid of into groove 511 when rotating by such bent axle 1, and then along groove
511 cell wall slide downward.Certainly, the oil outlet of oily passage 11 can also directly be opened in the side wall of the bent axle 1 of the downside of motor 5
On.
Bent axle 1 and the rotor 51 of motor 5 can be interference fitted, and can also be clamped or are bolted, be not limited thereto.
Similarly, can also be interference fitted between the cell wall of partition plate 2 and holding tank 34, or mutually clamping, welding etc..
