In the bi-directional swash plate type compressor, contacting between forward thrust bearing and front-bank rotor housing and the swash plate can be set to semi-rigid contact, contacting between back thrust-bearing and rear-bank rotor housing and the swash plate is set to flexible the contact; Perhaps contacting between forward thrust bearing and front-bank rotor housing and the swash plate is set to flexible contact, contacting between back thrust-bearing and rear-bank rotor housing and the swash plate is set to semi-rigid contact.
First embodiment of bi-directional swash plate type compressor
Fig. 2 shows first embodiment's of bi-directional swash plate type compressor cross-section structure, in the present embodiment, is set to semi-rigid the contact between forward thrust bearing and front-bank rotor housing and the swash plate, is set to flexible the contact between back thrust-bearing and rear-bank rotor housing and the swash plate.See also Fig. 2, the bi-directional swash plate type compressor of present embodiment comprises a pair of front-bank rotor housing 2, rear-bank rotor housing 3, a seal ring 4 is arranged between front-bank rotor housing 2 and rear-bank rotor housing 3, and plate member 7 before existing between front-bank rotor housing 2 and the protecgulum 14 exists back plate member 8 between same rear-bank rotor housing 3 and the bonnet 15.Front-bank rotor housing 2, rear-bank rotor housing 3 and protecgulum 14 and bonnet 15 and preceding valve plate 7 are connected by screw 16 with back valve plate 8 and fix.A live axle 1 passes protecgulum 14 and front-bank rotor housing 2 and rear-bank rotor housing 3, and swash plate 5 is housed on the live axle 1, is provided with forward thrust bearing 6A between swash plate 5 and the front-bank rotor housing 2, and is provided with back thrust-bearing 6B between the rear-bank rotor housing 3.Live axle 1 drives swash plate 5 and rotates in crankshaft cavity, moves reciprocatingly in the chamber of the preceding body of rod 2 and rear-bank rotor housing 3 thereby drive a plurality of pistons 17, finishes suction, compression and the discharging of refrigerant in cylinder 30.
Back thrust-bearing 6B between swash plate 5 and the rear-bank rotor housing 3 adopts the flexible way of contact, wherein the back thrusting plate 64b of back thrust-bearing 6B contacts with the minor diameter annular rib 3b of rear-bank rotor housing 3, and forward thrust sheet 63b contacts with the major diameter annular rib 5b of swash plate 5.Forward thrust bearing 6A between swash plate 5 and the front-bank rotor housing 2 adopts the semirigid way of contact, and wherein the back thrusting plate 62a of forward thrust bearing 6A contacts with the major diameter annular rib 5a of swash plate 5, and forward thrust sheet 61a contacts with the anchor ring 2a of front-bank rotor housing 2.Because the anchor ring on the front-bank rotor housing 2 is a bigger plane, the forward thrust sheet 61a of forward thrust bearing 6A offsets with it, when being subjected to axial impact force load, does not produce distortion substantially, and then the elasticity of thrust-bearing 6B is bigger.Effect after the distortion as shown in Figure 3.
Two thrust-bearing 6A, 6B have done different settings on the degree of resiliently deformable, so that better absorb thrust load on both direction, so that in the thrust load that produces, partial load is passed to cylinder body when better absorbing compressor operating.
Second embodiment of bi-directional swash plate type compressor
The difference of the bi-directional swash plate type compressor of present embodiment and first embodiment's bi-directional swash plate type compressor is to be provided with an elastomer between forward thrust bearing and front-bank rotor housing.
Fig. 4 shows the structure that the thrust-bearing of the bi-directional swash plate type compressor of present embodiment is installed, for other structures of bi-directional swash plate type compressor, owing to be prior art, and shown in Figure 2, do not giving unnecessary details at this.As shown in Figure 4, forward thrust bearing 6A between swash plate 5 and the front-bank rotor housing 2 adopts the semirigid way of contact, wherein the thrust-bearing 6A between forward thrust sheet 61a and the front-bank rotor housing 2 adopts the semirigid way of contact, wherein between forward thrust sheet 61a and the front-bank rotor housing 2 elastomer 20 is set, back thrusting plate 62a contacts with the annular rib 5a of swash plate 5.Back thrust-bearing 6B between swash plate 5 and the rear-bank rotor housing 3 adopts the flexible way of contact, and wherein forward thrust sheet 63b contacts with the major diameter annular rib 5b of swash plate 5, and back thrusting plate 64b contacts with the anchor ring 3b of rear-bank rotor housing 3.Because elastomer 20 can produce axial shrinkage when being subjected to thrust load, cause forward thrust bearing 6A to produce whole moving, the buffering axial impact, then thrust-bearing 6B can produce local distortion by a small margin, alleviates axial impact.
The 3rd embodiment of two-way slant plate type compressor
Fig. 5 shows the structure that the thrust-bearing of the two-way slant plate type compressor of present embodiment is installed, for other structures of bi-directional swash plate type compressor, owing to be prior art, and shown in Figure 2, do not giving unnecessary details at this.As shown in Figure 5, the forward thrust bearing 6A between swash plate 5 and the front-bank rotor housing 2 adopts the semirigid way of contact, and promptly forward thrust sheet 61a contacts with front-bank rotor housing anchor ring 2a, and back thrusting plate 62a contacts with swash plate annular rib 5a.The semirigid way of contact of the same employing of back thrust-bearing 6B between swash plate 5 and the rear-bank rotor housing 3, promptly forward thrust sheet 63b contacts with swash plate annular rib 5b, and back thrusting plate 64b contacts with rear-bank rotor housing anchor ring 3b '.
Present embodiment has more obviously effect to the high frequency oscillation that prevents to occur in the compressor operating, but the rigidity of the cooperation of rigid bearing is bigger than above-mentioned two embodiments, and is therefore not obvious for the absorption of impulsive load.
