Abstract
A bidirectional swash plate compressor has a main shaft supporting structure, which has low manufacturing cost and allows a compressor to operate normally at a high rotation speed. The bidirectional swash plate compressor comprises a compressor housing, a main shaft, a swash plate and pistons, wherein the main shaft is supported in the compressor housing in a rotating manner, the swash plate is fixed on the main shaft, the pistons in the cylinder holes of the compressor housing are arranged around the swash plate, and a valve plate component is arranged on the two end surfaces of the compressor housing respectively, and comprises a valve plate, an air suction valve plate arranged between the valve plate and a cylinder body, and an air exhaustion valve plate arranged on the other side of the valve plate. The bidirectional swash plate is characterized in that the main shaft is supported in the compressor housing through two angular contact ball bearings.
Description
Technical field
The utility model relates to a kind of compressor, relates in particular to a kind of oblique tray type compressor.
Background technique
Fig. 1 shows the structure of the existing bi-directional swash plate type compressor that is used for Vehicular air-conditioning apparatus.As shown in Figure 1, this structure has a pair of front-bank rotor housing 2 and rear-bank rotor housing 3, and screw 16 forms crankshaft cavity 40 with front-bank rotor housing 2 and rear-bank rotor housing 3 and tight.Swash plate 5 is run through by live axle 1 (main shaft) and is fixed on the live axle 1, and two thrust-bearings 6 are located at respectively between swash plate both sides and front-bank rotor housing 2, the rear-bank rotor housing 3, limits the axial position of swash plate and main shaft.Be respectively arranged with needle bearing 4 between the mesopore of main shaft 1 and front and rear cylinder 2,3, be used to keep the radial position of main shaft.When screw 16 passed protecgulum 14, front-bank rotor housing 2, rear-bank rotor housing 3 and bonnet 15 and tightens, the swash plate 5 between two thrust-bearings and thrust-bearing was clamped.When live axle 1 drive swash plate 5 rotated, a plurality of pistons 17 on the swash plate 5 were reciprocating, open when suction valve chip is beaten refrigerant is sucked cylinder 30, and cylinder is discharged in the compression back.
In adopting the air-breathing compressor of rotary valve, for example among the patent US5401144, as shown in Figure 2,, thereby there is not the space mounting needle bearing owing to rotary valve 18 is contained between main shaft and the front and back cylinder body mesopore.Adopt tapered roller bearing 9a, 9b can axial simultaneously, radial support main shaft.
In the compressor shown in Figure 1, shared 4 bearings respectively to 4 positions of main shaft axially, radially support, this structure manufacture cost is than higher.And the structures that adopted 2 tapered roller bearings to support in the compressor shown in Figure 2, the rotating speed of tapered roller bearing is limited in 10000 rev/mins, surpass 10000 rev/mins compressor and occurred now designing requirement, during operation under the spindle speed tapered roller bearing fragile.
The model utility content
The utility model provides a kind of bi-directional swash plate type compressor, and it has the spindle support structure that manufacture cost reduces, and this structure allows compressor normally operation under high rotating speed.
Bi-directional swash plate type compressor of the present utility model, comprise compressor housing, be rotatably supported in main shaft in the compressor housing, be fixed on swash plate on the main shaft, be arranged on around the swash plate, be positioned at the piston of the cylinder-bore of compressor housing, the both ends of the surface of compressor housing are provided with valve board assembly respectively, valve board assembly comprises the suction valve chip between valve plate, valve plate and the cylinder body and the exhaust valve plate of valve plate opposite side, be characterized in that main shaft is bearing in the compressor housing by two angular contact ball bearings.
Described bi-directional swash plate type compressor, its further characteristics are that described two angular contact ball bearings are contained in respectively in the front end housing and back cylinder cover of compressor housing.
Described bi-directional swash plate type compressor, its further characteristics are to have the gap between the mesopore of the cylinder body of main shaft and compressor housing.
The beneficial effects of the utility model are:
Adopt angular contact ball bearing to replace original needle bearing and thrust-bearing combination, can bear the radial and axial load that main shaft is subjected to simultaneously in rotation, the angular contact ball bearing precision is higher, noise is less, price is lower than tapered roller bearing, adapt to high speed conditions, can reach 22000 rev/mins, it is especially outstanding to be arranged in the bi-directional swash plate type compressor of high speed rotating speed performance; In the cylinder cap, the cylinder mesopore needn't play supporting role, and can keep the gap between main shaft and the cylinder body mesopore before and after bearing can be installed in, and the requirement on machining accuracy of cylinder mesopore can reduce.

Embodiment
As shown in Figure 3, the bi-directional swash plate type compressor in the car air conditioner comprises front end housing 41, front-bank rotor housing 49, rear-bank rotor housing 59, back cylinder cover 51, and a plurality of bolts 60 of front end housing 41, front-bank rotor housing 49, rear-bank rotor housing 59 and back cylinder cover 51 usefulness run through the formation compressor case.Comprise air aspiration cavity 42,52, exhaust cavity 44,54 that crankshaft room 61, forward and backward cylinder cap provide in the compressor case.Be provided with valve board assembly 20 between front and rear cylinder and the forward and backward cylinder cap and comprise suction valve chip, valve plate and exhaust valve plate.
Between main shaft 62 and the front end housing 41 sealing 65 is set, prevents that outside air from entering crankshaft room 61.Main shaft 62 middle parts are swash plate 66 fixedly, and array has a plurality of pistons 67 around the swash plate 66, and the two ends of piston 67 are contained in respectively in two corresponding cylinder- bore 45,55 of front and back.A pair of crawler shoe 68 is set between the piston seat at each piston 67 middle part and the swash plate 66, crawler shoe 68 1 side planes contact with swash plate 66, the opposite side semi circular surface contacts with the pit of piston 67, because crawler shoe variable-angle ground cooperates, swash plate 66 can be free to slide in piston seat.Piston 67 is during away from the valve board assembly 20 of correspondence, and the exhaust valve plate of valve board assembly 20 is closed, suction valve chip is opened, and cylinder-bore sucks refrigerants from air aspiration cavity 42 or 52; Piston 67 is during towards 20 motions of corresponding valve board assembly, and the suction valve chip of valve board assembly 20 is closed exhaust valve plate and opened, with the compression of the refrigerants in the cylinder-bore 55 and be discharged to exhaust cavity 44 or 54.
The back side bearing 64 of two angular contact ball bearings also can be installed in the cylinder mesopore, and main shaft 62 need not pass the cylinder block mesopore, and length can shorten.
