Abstract
The invention discloses an oil inlet device of a vortex type electrical air conditioner compressor, relating to the technical field of manufacturing of compressors. The oil inlet device of the vortex type electrical air conditioner compressor comprises a motor shaft provided with an eccentric shaft section, wherein the motor shaft is arranged in a center hole of a bearing block in a penetrating manner through a bearing sleeving the motor shaft, the bearing block is provided with a locating part pushing against an inner ring of the bearing, the bearing block is provided with multiple vent holes distributed circumferentially and communicated with a bearing ball slideway at the locating part, and an oil screen is arranged at the outer side of each vent hole. Compared with the prior art, the oil inlet device can solve the problems that the service life of the bearing is short and the noise is high due to an oil mist mixed gas inlet mode of the existing vortex type electrical air conditioner compressor.
Description
Technical field
The present invention relates to scroll compressor manufacturing technology field, especially a kind of oil feeding device for swirl motor air condition compressor.
Background technique
At present, there is a kind of vortex air conditioner compressor as shown in Figure 1 on the market, this vortex air conditioner compressor is included in the motor shaft 10 that one end shaft shoulder is provided with eccentric shaft part 101, one end that this motor shaft 10 is coated with rotor is fixed on the bottom of casing 40, motor shaft 10 end being provided with eccentric shaft part 101 is installed in bearing support 20 by the bearing 30 that it is sleeved on the shaft shoulder, and this bearing support 20 is provided with the ring washer portion of support bearing outer ring; In bearing support 20, be provided with the orbiter engaged with fixed scroll, this orbiter is sleeved on the eccentric shaft part of described motor shaft with balance soon by the sliding bearing be mounted in it in central hole.During work, the oil gas being mixed with mist of oil enters from the suction port being located at casing and being equipped with one end of rotor, enters work chamber, lubricating bearings and each movement parts by the annular inlet passageway between bearing support and the motor shaft shaft shoulder, bearing ball slideway.In use there are the following problems for the intake method of this oil gas: due to be mixed with mist of oil oil gas in containing fine particle impurity, these fine particle impurity enter the wearing and tearing that bearing ball slideway and work chamber not only easily accelerate bearing ball, make it the lost of life; Swirl motor air condition compressor noise in operation process also can be made large, even exceed standard.
Summary of the invention
Problem solved by the invention is to provide a kind of swirl motor air condition compressor oil feeding device, easily causes with the intake method being mixed with the gas of mist of oil solving existing swirl motor air condition compressor the problem that bearing life is short and noise is large.
In order to solve the problem, the technical solution used in the present invention is: this swirl motor air condition compressor oil feeding device, comprise the motor shaft being provided with eccentric shaft part, described motor shaft is installed in the center hole of bearing support by its upper bearing (metal) of suit, described bearing support is provided with the positioning part abutted against with the inner ring of described bearing, described bearing support be provided with in this positioning part multiple circumferentially distribute and be communicated with the vent of described bearing ball slideway, be equipped with an oil screen in the outside of each described vent.
In above-mentioned swirl motor air condition compressor oil feeding device technological scheme, technological scheme can also be more specifically: on described motor shaft, be set with shaft seal, and described shaft seal is fixed in the annular groove of described bearing support center hole between described bearing and described oil screen.
Further: the end face of described bearing support in nearly described eccentric shaft part side is provided with many and goes out oil groove.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, owing to the annular inlet passageway on bearing support to be changed into multiple vent that circumferentially distributes, and be provided with an oil screen in the outside of each vent, the oil gas entering gas-entered passageway is filtered, make the fine particle impurity in oil gas can not enter bearing ball slideway and work chamber, thus improve the working life of bearing, make noise in swirl motor air condition compressor operation process little; 2, owing to being set with shaft seal on motor shaft, shaft seal is fixed in the annular groove of bearing support center hole between bearing and described oil screen, the lubricant oil be deposited on the motor shaft being positioned at eccentric shaft part side can not enter bearing ball slideway and work chamber, thus guarantee the turbidity test of lubricant oil; 3, on the end face of the nearly eccentric shaft part side of bearing support, be provided with out oil groove, unnecessary lubricant oil recycles by going out oil groove discharge.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing swirl motor air condition compressor.
Fig. 2 is the structural representation of the embodiment of the present invention.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the right elevation of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Swirl motor air condition compressor oil feeding device as shown in Figure 2 comprises the motor shaft 1 being provided with eccentric shaft part 1-1, motor shaft 1 is installed in the center hole of bearing support 2 by its upper bearing (metal) 3 of suit, bearing support 2 is provided with the positioning part abutted against with the inner ring of bearing 3, the present embodiment have on the positioning part of bearing support 2 four circumferentially distribute and be communicated with the vent 2-1 of bearing ball slideway, the bearing ball slideway between bearing outer ring and inner ring of four vent 2-1 is gas-entered passageway, an oil screen 5 is all equipped with in side in the outside of each vent namely near rotor, a counterbore coordinated with oil screen 5 fitting seat crest clearance is had in each vent and end face outside joint, oil screen 5 is riveted on the counterbore of vent, be provided with three in the end face of nearly eccentric shaft part 1-1 side shaft holder 2 and go out oil groove 2-2.Motor shaft 1 is set with shaft seal 4, and shaft seal 4 is fixed in the annular groove of bearing support 2 center hole between bearing 3 and oil screen 5.
During work, oil gas just can enter gas-entered passageway by oil screen 5, oil screen 5 makes the fine particle impurity in oil gas can not enter bearing ball slideway and work chamber, thus improves the working life of bearing, makes to keep little noise in swirl motor air condition compressor operation process.
