Abstract
The utility model comprises a refrigeration compressor, comprising a main shaft, a swash plate, a Planetary plate, a steel ball, bevel gears, a double-head connecting rod and a piston. One end of the main shaft is connected with the swash plate, a needle bearing is arranged between a slope of the swash plate and the planetary plate, the bevel gear fixed on the planetary plate is meshed with the bevel gear on the machine body through the steel ball, the planetary plate and the piston are respectively connected with the two heads of the double-head connecting rod, the steel ball, the two heads of the double-head connecting rod and a contact wall of the piston and a cylinder are all coated with a solid lubricant coating, when the compressor accelerates suddenly, the movable friction parts can be lubricated with no easy damage, and the service life is extended.
Description
The utility model relates to air conditioning equipment of car, is meant the automobile refrigeration compressor particularly.
Existing automobile refrigeration compressor, as the rocking plate type compressor under normal operating condition, the mist lubrication oil that the body inner chamber is formed by the high-speed motion of moving element abrim, movable friction position obtains the lubricated of vaporific lubricant oil and proper functioning, and indexs such as its performance, life-span and stability all can meet technical standard and user's usage requirement.In early days in the using process, when for some time state of rest of compressor place, lubricant oil is not atomized movable friction position and can not get lubricating, if this moment, the compressor sudden change was quickened, promptly from the static unexpected 5000rpm that raises speed, in addition higher, because the compressor internal lubricating system does not catch up with, cause movable friction position lack of lubrication, obviously can cause compressor impaired and the lost of life even inefficacy like this.
The purpose of this utility model is to overcome the shortcoming that above-mentioned compressor exists, the refrigeration compressor that provide a high lubricating effect, easily starts and suddenly change and quicken.
To achieve these goals, the utility model adopts following technological scheme: the same with existing refrigeration compressor, mainly include main shaft in this compressor body, swash plate, planetary plate, steel ball, umbrella gear, bipitch connecting rod, piston, main shaft one end connects swash plate, be provided with needle bearing between the inclined-plane of swash plate and the planetary plate, fixing umbrella gear is meshed with umbrella gear on the body by steel ball on the planetary plate, planetary plate links to each other with two of bipitch connecting rod respectively with piston, and institute's difference is: at steel ball, bipitch connecting rod two, and piston is coated with the solid lubricant coating with the wall that contacts of cylinder.
Because the utility model adopts steel ball, bipitch connecting rod two and the piston in compressor to be coated with solid lubricant with the wall that contacts of cylinder, make compressor when sudden change is quickened, the movable position that rubs is lubricated, be difficult for impaired, life-saving.
Below in conjunction with drawings and Examples, the utility model is done one describes in detail:
Fig. 1 is the utility model structural profile schematic representation.
See also shown in Figure 1, mainly include main shaft 1, swash plate 2, planetary plate 5, steel ball 16, umbrella gear 14 and 17, bipitch connecting rod 7, piston 11 in the refrigeration compressor, main shaft 1 one ends connect swash plate 2, between the inclined-plane 3 of swash plate 2 and the planetary plate 5 needle bearing 4 is arranged, fixing umbrella gear 17 is meshed with umbrella gear 14 on the body 13 by steel ball 16 on the planetary plate 5, like this, planetary plate 5 just can not rotate and can only be close to swash plate inclined-plane 3 to do with steel ball 16 along with the rotation of main shaft 1, swash plate 2 be the swing at center.Planetary plate 5 links to each other with two of bipitch connecting rod 7 respectively with piston 11, the swing of planetary plate 5 drives the bipitch connecting rod 17 and the piston 11 that are attached thereto and does axial motion, fluid in the compression cylinder 8, the number of the bipitch connecting rod in the compressor of reality is identical with the number of cylinder, when each bipitch connecting rod and piston 11 are done axial motion, compress the fluid in each cylinder.In above-mentioned structure, when main shaft 1 high speed rotating, steel ball 16 and umbrella gear 14, the activity friction position of umbrella gear 17, planetary plate 5 and piston 11 and the movable position that rubs, two of bipitch connecting rod 7, piston 11 all bears violent rubbing action with the activity friction position of cylinder 8, especially when compressor is starting or when accelerating to high-speed state suddenly, it is even more serious to rub, in order to prevent the generation of this situation, at above-mentioned position, promptly at steel ball 16, two of bipitch connecting rod 7, and piston 11 is coated with solid lubricant coating 15 respectively with the wall that contacts of cylinder 8,6,12,9,10, solid lubricant can adopt as phosphatization, anodization, soft metal and fluororesin etc., because these solid lubricants have oil storage or self-lubricating property, therefore can not damage each component of compressor.
The utility model is applicable to the compressor of other types too.
