Abstract

The utility model provides an oil-way structure of an automotive air conditioning vortex compressor, which is characterized in that a pore is arranged at the end surface of the front cover of the structure, an annular groove is arranged around an assembly surface of the front cover and a wear-resisting disc, the bottom of the pore is communicated with the annular groove through an inclined hole, a top groove is arranged at the external edge of the wear-resisting disc, a bottom groove is arranged at the internal edge of the wear-resisting disc, and a channel for communicating the bottom of a high-pressure area inside the automotive air conditioning vortex compressor with the pore is arranged on the wall of a vortex fixing disc. The oil-way structure leads lubricating oil separated from a high-pressure area oil separator into a low-pressure area through the pore so as to spray and lubricate bearings and scrolls. Therefore, the bearings can not be lack of lubrication, noises are low, and service life of the bearing can be prolonged.

Description

Car air conditioner scroll compressor oil channel structures

Technical field

The utility model relates to a kind of car air conditioner scroll compressor oil channel structures, can be used for improving car air conditioner scroll compressor in use moving element oil starvation or lubricated deficiency, prolong bearing life, reduce the noise that running produces, belong to car air conditioner scroll compressor technical field of structures.

Background technique

At present, scroll compressor is very rapid in China development, and, advantages such as component few, high rotating speed little with volumetric efficiency height, Energy Efficiency Ratio height, vibration are favored gradually.Just because of therefore the high rotating speed of scroll compressor needs one to overlap lubrication system efficiently.Because if it will be fatal concerning compressor that oil starvation or lack of lubrication make damage of bearings.

As shown in Figure 1, the refrigerant that contains lubricant oil during the work of traditional car air conditioner scroll compressor enters low-pressure cavity from suction port, along with the revolution motion of movable orbiting scroll enters the bearing bore lubricating bearings from first waist-shaped hole 1 and second waist-shaped hole 2.But not only do not had pressure difference between two waist-shaped holes but also can not form convection current, and original contained lubricant oil is just few in the refrigerant, so really can provide lubricated oil seldom to bearing, cause the bearing lubrication deficiency, noise increases, and causes bearing to damage in advance.

Summary of the invention

The purpose of this utility model provides a kind of vortex of car air conditioner efficiently compression oil channel structures.

In order to achieve the above object, the technical solution of the utility model has provided a kind of car air conditioner scroll compressor oil channel structures, it is characterized in that: comprise the pore of being located on the protecgulum end face, around protecgulum and wear-resisting dish mating face, have a ring annular groove, the bottom of pore communicates with circular groove by inclined hole, having groove on the cylindrical of wear-resisting dish, on the interior circle of wear-resisting dish, have a following groove, on the wall of static vortex disk, have a passage that makes that bottom, the zone of high pressure in the car air conditioner scroll compressor communicates with pore.

Further, the sectional area of described pore is 0.2～2mm2, and the sectional area that passes through area and described pore of described upward groove and described groove down is suitable.

The lubricant oil that the utility model is separated the zone of high pressure oil separator is introduced low pressure area by pore bearing and scroll is carried out spray lubrication, therefore makes the bearing sufficient lubrication, and noise is less, and prolongs bearing working life.

Embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

Extremely shown in Figure 4 as Fig. 2, a kind of car air conditioner scroll compressor oil channel structures that the utility model provides comprises the pore of being located on protecgulum 3 end faces 4, around protecgulum 3 and wear-resisting dish 5 mating faces, have a ring annular groove 6, the bottom of pore 4 communicates with circular groove 6 by inclined hole, having groove 7 on the cylindrical of wear-resisting dish 5, on the interior circle of wear-resisting dish 5, have a following groove 8, on the wall of static vortex disk 9, have a passage that makes that 10 bottoms, zone of high pressure in the car air conditioner scroll compressor communicate with pore 4.The sectional area of pore 4 is 0.2～2mm2, and the sectional area that passes through area and described pore 4 of groove 8 was suitable under described upward groove 7 reached, and length is adjusted according to movable orbiting scroll diameter and spindle eccentricity distance.

Wearing plate 5 cylindricals become to be slidingly matched with protecgulum 3 endoporus, and matching gap is 0.01-0.025mm.Enter the pore 4 of protecgulum 3 with certain pressure when lubricant oil after, will be from last groove 7 ejections of wearing plate 5.When movable orbiting scroll runs to the quadrant position, through lubricated anti-rotation mechanism in movable orbiting scroll bottom and main bearing, flow out from the following groove 8 of wearing plate 5 from the oil of last groove 7 ejection of wearing plate 5.When movable orbiting scroll runs to the lower quadrant position, following groove 8 sealings, lubricant oil is from the lubricated scroll of last groove 3 ejections of wearing plate 5.Other positions are for lubricated simultaneously.
