Description

The oil feed device of horizontal-type compressor

Technical field

The present invention is meant to be applied in a kind of comparatively small-sized rotary compressor about a kind of oil feed device of horizontal-type compressor especially, makes compressor installing and using when tilting the place uneven, still can provide parts necessary lubricious oil supply and Oil Guide function effectively.

Background technique

A kind of horizontal-type compressor, can be applied to the refrigerating and air conditioning system or the heat radiation of electronic product, be particularly useful for such as on the portable carriers such as automobile, for example Portable refrigerator, car air-conditioner etc., and be the needs that adapt to installing space, adopt horizontal (horizontal) design more.Because compared to rectilinear design, the oilhole of horizontal (lubrication bore) is bigger with the distance of pasta, the fuel feeding difficulty improves relatively.Therefore, for this horizontal-type compressor, whether lubricant oil can be supplied with effectively, become main problem with inner each parts of lubricate compressors, especially at the horizontal-type compressor that partly is installed on the moving carrier, because of compressor often must be in heeling condition, under this kind situation, internal works can effectively be supplied with and be guided to lubricant oil whether, will obviously influence the working life of compressor.

In existing prior art, a lot of at providing the horizontal-type compressor parts to fill part lubricated design.For example the U.S. the 4th, 472, case before No. 121 " Horizontal rotary compressor with oil forced by gasdischarge into crankshaft bore " patents.Please cooperate referring to Figure 1 and Figure 2, it mainly utilizes in a compressor housing 1a of sealing, to be located at a coolant discharging pipe 3a and an oil gas pipe 5a socket each other of compressor housing 1a one side, and its socket place is positioned at below the lubricant oil 7a oil collecting zone liquid level of compressor housing 1a bottom.Simultaneously since the caliber of oil gas pipe 5a greater than coolant discharging pipe 3a, make its socket place form a gap 9a, when the cold media air of high pressure enters oil gas pipe 5a via coolant discharging pipe 3a, the mixed oil and gas that cold media air is mixed because of the pressure difference effect with lubricant oil is inhaled into oil gas pipe 5a simultaneously, be positioned at the oil gas accumulator tank 11a of arbor side again via oil gas pipe 5a injection one, by a rotation of being located at the helical flabellum 13a in the arbor lubricant oil 7a is imported the axis hole 15a inside of arbor then, and then reach the purpose of lubricated internal works.

Only, case design before the aforesaid U. S. Patent, owing to be arranged at a side position of compressor by the composite tube of coolant discharging pipe 3a and oil gas pipe 5a socket each other, therefore when compressor is located at fixed flat carrier, refrigerator etc. for example, this design still can be kept the normal lubrication of compressor internal works, yet when it is located at portable carrier, automobile for example, and be positioned at climbing during the position, then the Yi Fashengyin level inclination is excessive and make lubricant oil 7a liquid level tilt, and makes this composite tube break away from liquid level and can't normally draw the phenomenon of lubricant oil 7a, and then the compressor internal works can't normally be lubricated, so that influence its working life.

Secondly, for another the preceding case of the 5th, 221, No. 191 " Horizontal rotary compressor " patents of the U.S., please cooperate shown in Figure 3.Mainly be provided with one in the inner side of the compressor of a sealing and be down L shaped strike the oil pipe 1b, its upper end is installed on the hollow bearing lid 7b of arbor 3b one step bearing 5b, and the lower end then deeply is positioned under the oil collecting zone liquid level of compressor bottom lubricant oil 9b.In addition, end in addition at compressor shaft 3b then is provided with a rotatable axial flow fan 11b, when turning round, drive axial flow fan 11b by arbor 3b, make the inner axis hole 13b of arbor 3b produce suction force because of pressure reduction, and then after lubricant oil 9b can be extracted via strike the oil pipe 1b, import bearing 5b and the inner axis hole 13b of arbor 3b by bearing cap 7b again, to reach purpose to oil lubrication.

Case before the aforementioned known U. S. Patent, its oil supplying device mainly utilizes the axial flow fan 11b that the is positioned at arbor 3b one side pressure reduction of axis hole 13b at axial position that causes when subsidiary arbor 3b revolution, and lubricant oil 9b is aspirated and enters internal works and be lubricated through falling L shaped strike the oil pipe 1b.Case before right this known patent, though because of it adopts a kind of L shaped strike the oil pipe 1b of falling, can improve a little that time institute's lubricant oil 9b liquid level that may cause descends because of horizontal tilt when compressor, the lack of lubrication phenomenon that can't normally aspirate and cause, but when the compressor inclination angle is excessive, the L shaped strike the oil pipe 1b that falls still possibly can't effectively draw the lubricant oil 9b that descends because of the inclination liquid level, study carefully it and be arranged at a side of compressor because of promptly being strike the oil pipe 1b, and lubricant oil 9a liquid level descends and easily causes the strike the oil pipe 1b mouth of pipe to break away from liquid level and normal strike the oil when tilting, and then causes the compressor internal works can't obtain normal fuel injection lubricating.Moreover, in the preceding case of aforementioned known U. S. Patent, because axial flow fan 11b is when running, fluid is flowed vertically, that is to say the axial inner pressure difference that must be produced by a side axial flow fan 11b and strike the oil pipe 1b interaction, could produce the kinetic energy of suction, therefore, must produce longer pipe spare and foot for the axial flow fan 11b that implements this working principle, yet when pipe fitting is long more, just get over the shape difficulty in the collocation, often derive the situation that also becomes complicated on the structure, and thereby improve the difficulty of making processing, influence is in one's power, manufacture cost also improves relatively, and product competitive ability then reduces.

Therefore, for solving the deficiency and the disappearance of aforementioned prior art, be necessary to develop and a kind of new design, this design not only can reach economic, economical purpose, the lubricated of parts can still can effectively be provided with the different horizontal tilt angle of compressor simultaneously, guaranteeing the normal operation of compressor, and then prolong its working life.

Summary of the invention

The invention provides a kind of horizontal-type compressor oil feed device, the main centrifugal cutter that at least one subsidiary arbor rotation is installed on the arbor between compressor internal motor rotor and cylinder axis frame, and near arbor and centrifugal cutter socket place, that is below flabellum, be equipped with several oil outlets.In addition, in the geometrical center position near compressor, promptly the strike the oil hole is established in sliding bearing bottom, the design in the inner Oil Guide of collocation arbor duct, and be connected with the oil outlet of aforementioned arbor.Wherein, the Oil Guide duct comprises at least one radially fuel-displaced duct that is reached the axle center by the downward extension of arbor oil outlet deeply; An axial oil duct that is drilled with by the endface position of arbor is as main oil leab, and it is deep hole formula design, and reaches deeply and aforementioned radially duct forms quadrature; That establishes in addition in arbor and sliding bearing socket position at least onely radially goes into the neck location that the oilhole road reaches sliding bearing deeply, communicate with axial oil duct, and be provided with at least one radially strike the oil duct in the same position of sliding bearing, the bottom in duct is a strike the oil hole, and it is positioned at below the oil collecting zone liquid level of compressor bottom; And, in the cylinder cover plate be provided with one radially the strike the oil duct communicate with the aforementioned axial oil duct, and its bottom also is provided with a strike the oil hole, also is positioned at below the oil collecting zone liquid level of compressor bottom.

When centrifugal cutter rotates, because pressure gradient effect, interval between flabellum and arbor oil outlet forms low pressure area, make the lubricant oil that is positioned at the compressor bottom, see through with arbor that oil outlet is connected in axial oil duct, and the sliding bearing of inner intercommunication strike the oil duct and cylinder cover plate strike the oil duct etc. radially radially, via each strike the oil hole of each bottom, strike the oil duct by pumping after, being guided to each parts inside via described Oil Guide duct again finishes lubricated, go out by oil outlet place jet flow on the described arbor more at last, and got rid of back the bottom oil collecting zone of compressor by centrifugal cutter, to form lubricated circulating oil path.

By above-mentioned design, because one of strike the oil hole is positioned at the bottom of sliding bearing, approach the geometrical center position of compressor, therefore compressor is as because of horizontal tilt angle when excessive, this strike the oil hole still can be in below the liquid level of lubricant oil, in other words, still can keep the normal lubricated of compressor internal works and the not influence at machine angle of inclination by compression, and then can improve the restriction that known techniques is subject to the influence of horizontal tilt angle, cause the situation of lack of lubrication to take place.Simultaneously because centrifugal cutter also approaches the geometrical center of compressor, even with the strike the oil hole that is positioned on the cylinder cover plate, distance also is unlikely long, so can improve pressure gradient by this, draws the ability of lubricant oil with the lifting centrifugal cutter.In addition, utilization of the present invention is fixedly arranged on the centrifugal cutter on the arbor, the lubricant oil Oil Guide duct design of collocation arbor internal structure intercommunication, and structurally most simple and easy processing, thereby also have the economic value that reduces manufacture cost.
