Description
Technical field
The present invention relates to a kind of air condition compressor, relate in particular to the air conditioner compressed machine core supporting structure of a kind of change discharge capacity.
Background technique
Air condition compressor is the requisite equipment of temperature regulation in automobile, and Main Function is for compression and refrigerant conveying.Air condition compressor is divided into by the inner workings difference: crank-linkage type (by crank, connecting rod, piston, the compositions such as air inlet and exhaust valve); Wobble plate type compressor (by main shaft, cone gear, oblique plate, connecting rod, piston, the compositions such as inlet and discharge valve and rocker); Three kinds of oblique tray type compressors (by main shaft, swash plate, cylinder, piston, the compositions such as inlet and discharge valve).According to the version of refrigeration discharge capacity, air condition compressor can be divided into fixed displacement compressor and variable compressor.
The core structure of variable compressor forms and comprises live axle, swash plate, valve body, pressing chamber, piston, return spring, crankcase etc.During work, the rotation of main shaft drives the rotation of swash plate, and the swash plate edge promotes piston and makes axially reciprocating, completes air-breathing, compression, exhaust.In order to make compressor operating steady, need to guarantee the installation accurate positioning of main shaft.Traditional localization method is the station-keeping mode that adopts sliding bearing, fore-end at main shaft is covered with alloy coat, using the front end cylindrical of main shaft as the radial location face of main shaft, using the shaft shoulder of intermediate portion of main shaft as axial locating surface, shaft shoulder place also is covered with alloy coat, directly fore-end and the spindle end face portion at main shaft is covered with alloy coat, valve body is in front-end of spindle section, endoporus is for becoming diametric hole, and the front end cylindrical of axle and the shaft shoulder have the slip lubrication channel effectively to work to guarantee two locating face when work.Traditional localization method has its superiority, can directly be placed on front-end of spindle section to valve body, and the opening and closing of valve body are that the position forwarded to by axle determines, valve body does not have other opening and closing structure, has saved the device space and structure.But this structure has following shortcoming: the technological requirement of (1) alloy coat is very high, is difficult to guarantee long-time effectively work under high speed; (2) additional lubrication channel requires that good greasy property is arranged, and ensures and maintain the lubricant oil good flow difficult of lubrication channel; (3) repair difficulty after the axle head fret wear, affect the motion of main shaft stationarity, thereby have influence on the performance of whole compressor.
Summary of the invention
The object of the invention is to propose the air conditioner compressed machine core supporting structure of a kind of change discharge capacity, it can reduce the processing technology difficulty of main shaft, improves the reliability of equipment, guarantees to become discharge capacity air condition compressor stable working.
For reaching this purpose, the present invention by the following technical solutions:
The air conditioner compressed machine core supporting structure of a kind of change discharge capacity, it comprises housing, valve body, movement main shaft and core part, wherein, described housing comprises the front case be fixed as one, middle casing and rear case, an end and its cylindrical that described valve body is arranged at the inner chamber of middle casing contact with the inner chamber of middle casing, one end of described movement main shaft is arranged on described valve body by the long needle bearing of front end, the other end is arranged on rear case by the supporting of the long needle bearing in rear end, described core part is arranged on described movement main shaft, be provided with needle roller thrust bearing between described core part and rear case.
Especially, the needle roller length of the long needle bearing of described front end is 20～80mm, and diameter is 5～15mm; The needle roller length of the long needle bearing in described rear end is 20～80mm, and diameter is 5～15mm; The needle roller length of described needle roller thrust bearing is 30～80mm, and diameter is 5～15mm.
Especially, on described front case, middle casing and rear case, correspondence offers attachment hole, and connecting bolt is connected as a single entity each housing through described attachment hole.
Beneficial effect of the present invention is:
1, the processing request that becomes the air conditioner compressed machine core supporting spindle of discharge capacity is reduced, do not need to be covered with alloy coat;
2, with the supporting positioning form of needle bearing, do not need the lubricated ad hoc requirement of sliding, reduced the requirement to working environment, improve the reliability of work.
3, the front end of movement main shaft and rearward end adopt long needle bearing structure, to guarantee radial location precision and the reliability of supporting spindle, core part adopt long needle thrust bearing as axially locating, with axially locating precision and the reliability of assurance core part.
