Description
Technical field
The present invention relates to the structures that a kind of electric scroll compressor bearing is cooling and lubricates, and belong to electric scroll compressor skill
Art field.
Background technology
The energy and problem of environmental pollution are one of the significant problems that the world today faces, and the energy is modern society and life
Material base, as world population and economic increase sharply, the consumption of the energy sharply increases, and environmental pollution is caused constantly to add
It is acute.
Electric scroll compressor is energy-efficient with its, low noise, it is stable the advantages that favored deeply by people.It is existing
Electric scroll compressor, as shown in Figure 1 (serial number 4 flows to for refrigerant), refrigerant is high by being formed after compression when the compressor is operated
Refrigerant 3 is pressed, is directly discharged from exhaust outlet 2, refrigeration oil can be discharged with high pressure refrigerant 3 in the process, then pass through entire air-conditioning system
A small amount of refrigeration oil is had after system can return to compressor with refrigerant, and in the whole process, low pressure refrigerant 5 enters from air entry 6
Then compressor enters dynamic fixed scroll 8 by compressor inner wall surrounding and is compressed, and the bearing on bearing block 7 and movable orbiting scroll 1
Pass through by a large amount of low pressure refrigerant 5, the friction generation high temperature in compressor operating so that bearing lubrication is bad, leads to bearing
Damage, when compressor operation, generate abnormal sound, final cisco unity malfunction.
Invention content
The technical problem to be solved by the present invention is to：It provides a kind of reduction compressor noise, promote compressor service life
Electric scroll compressor bearing is cooling and the structure of lubrication, solve the bearing block of existing electric scroll compressor and dynamic whirlpool
Bearing on disk passes through by a large amount of low pressure refrigerant so that bearing lubrication is bad, the problem of leading to bearing damage.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of electric scroll compressor bearing is cold
But and the structure of lubrication, which is characterized in that including flabellum, wear plate and bearing block, flabellum is set to below bearing block, and flabellum is sleeved on
On bearing, bearing block is equipped with oil-recovery tank, and wear plate is equipped with oil return hole, and oil return hole is connected with oil-recovery tank.
Preferably, the wear plate is set between flabellum and the oil-recovery tank of bearing block.
Preferably, inner space is equipped in the bearing block, wear plate and flabellum are respectively arranged on the upper and lower of inner space
Both ends.
Preferably, the oil return hole is evenly distributed on wear plate, and oil-recovery tank is evenly distributed in the side of bearing block
On edge, oil return hole is corresponding with the position of oil-recovery tank.
The present invention below compressor shaft bearing by loading onto a flabellum, then passes through wear plate and band with oil return hole
The bearing block for having oil-recovery tank, using the refrigeration oil mixed in the cooling of low pressure refrigerant and low pressure refrigerant to bearing lubrication, to protect
The lubrication of bearing is demonstrate,proved.Apply the present invention to existing electric scroll compressor, under the premise of not changing original structure, increases
Add a flabellum, improve the lubrication under long-time use, reduce the noise of compressor and improve compressor use the longevity
Life.Ensure that bearing of compressor will not cause internal lubrication bad because of freezing shortage of oil, bearing rapid wear after working long hours, system
The problem of reduction of cold and Energy Efficiency Ratio and cisco unity malfunction.

Specific implementation mode
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.
The present invention is the structure that a kind of electric scroll compressor bearing is cooling and lubricates, as shown in Figure 2 comprising flabellum 9
(as shown in Figure 3), wear plate 12 and bearing block 7, flabellum 9 are set to 7 lower section of bearing block, and flabellum 9 is sleeved on main shaft；On bearing block 7
Equipped with oil-recovery tank 10, as shown in Figure 5；Wear plate 12 is equipped with oil return hole 11, as shown in Figure 4.Oil return hole 11 connects with oil-recovery tank 10
It is logical.Wear plate 12 is set between flabellum 9 and the oil-recovery tank 10 of bearing block 7.Inner space, 12 He of wear plate are equipped in bearing block 7
Flabellum 9 is respectively arranged on the upper and lower ends of inner space.Oil return hole 11 is evenly distributed on wear plate 12, and oil-recovery tank 10 is uniform
It is distributed on the edge of bearing block 7, oil return hole 11 is corresponding with the position of oil-recovery tank 10.
In the structure that a kind of electric scroll compressor bearing provided by the present invention is cooling and lubricates, refrigerant flows to 4 such as
Shown in Fig. 2, after low pressure refrigerant 5 enters compressor, low pressure refrigerant 5 is sent by 7 inner space of bearing block by flabellum 9, by cold
The refrigeration oil mixed in matchmaker is cooled down and is lubricated to the bearing of bearing block 7 and movable orbiting scroll 1, then passes through returning on wear plate 12
Oilhole 11 enters the oil-recovery tank 10 on bearing block 7, finally flows back to compressor low pressure chamber and is inhaled into compression, wear plate in scroll plate 1
12 oil return hole 11 and 10 size of oil-recovery tank of bearing block 7 are designed with the requirement of recirculating oil quantity, to facilitate processing to be advisable.
Flabellum 9 and the wear plate 12 with oil return hole 11 and the bearing block 7 with oil-recovery tank 10 are packed into compressor.Work as electricity
In the running, low pressure refrigerant 5 is sent into 7 inner space of bearing block to dynamic vortex compressor by flabellum 9 so that low pressure refrigerant 5 is to high speed
The bearing of operating is cooled down, and the refrigeration oil by being mixed in low pressure refrigerant 5 is to bearing lubrication, then by wear plate 12
Oil return hole 11 enter the oil-recovery tank 10 on bearing block 7, finally flow back to compressor low pressure chamber and be inhaled into compression in scroll plate 1, lead to
Cross low pressure refrigerant 5 cooling and lubrication after enable bearing to keep working normally for a long time, to reduce entire compression
The noise decibel of machine, and also improve the reliability of compressor so that compression function is using the longer time without not
Workable phenomenon.
