[embodiment]
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
A kind of horizontal compressor with symmetrical double cylinder, as shown in Figure 2, comprise shell 1, motor 2 and bent axle 3, bent axle 3 is assemblied on the rotor of motor 2, the motor 2 of compressor is sealed in the shell 1, at interior respectively symmetrical the first compression unit 4 and the second compression unit 5 that is driven by bent axle 3 left and right end portions that be provided with of the shell 1 at motor 2 two ends; Described the first compression unit 4 comprises the first main bearing 40, the first cylinder 41, the first roller 42 and the first supplementary bearing 43, the first supplementary bearing 43, the first cylinder 41 are fixed in by bolt 6 and form the first compression work chamber 44 on the first main bearing 40, and the first roller 42 is installed on the left end of bent axle 3 in the first compression work chamber 44; Described the second compression unit 5 comprises the second main bearing 50, the second cylinder 51, the second roller 52 and the second supplementary bearing 53, the second supplementary bearing 53, the second cylinder 51 are fixed in by bolt 6 and form the second compression work chamber 54 on the second main bearing 50, and the second roller 52 is installed on the right-hand member of bent axle 3 in the second compression work chamber 54; Described bent axle 3 is comprised of main shaft 30 and a pair of excentric sleeve 31 that cooperates with the first roller 42, the second roller 52 respectively of straight line shape, described excentric sleeve 31 adopts the two ends that powder metallurgy is made and line is symmetricly set in main shaft 30 centered by main shaft 30 shaft axiss, and excentric sleeve 31 adopts pin block 32 to be assemblied on the main shaft 30.The axial oil supply hole 33 that compression unit and bearing fit section at bent axle 3 two end part offers respectively the axial blind hole state.
To shown in Figure 7, pin block 32 as required its cross section can be designed as square or is rectangular such as Fig. 4, simultaneously, for main shaft 30 moments of torsion stressed evenly, the both sides of pin block 32 embedding main shaft 30 of line symmetry centered by main shaft 30 shaft axiss.
The present invention adopts the main shaft 30 of straight line shape and a pair of excentric sleeve 31 to form by changing the assembly structure of bent axle, will have irregular bent axle now and be changed to two parts, and excentric sleeve 31 adopts powder metallurgy to make, and wear resistance is good, easily processing; During assembling, main shaft 30 outsides and excentric sleeve 31 inboard flutings, with pin block 32 lockings, pin block 32 height are a little less than the height of cylinder, make the do not wear and tear major and minor bearing plane of compression unit of pin block 32.Simultaneously, with reference to the fixing method of horizontal machine two end cap bearing, utilize symmetry principle, at two compression unit symmetrical operations of motor both sides design, both increased the discharge capacity of compressor, and avoided again the one-sided pump housing to cause motor to move without fulcrum, and made compressor operation steadily reliable.As shown in Figure 2, the exhaust mode that supplies of the present invention adopts two groups of air supply pipes and outlet pipe respectively to the first compression unit 4 and the second compression unit 5 air feed and exhaust.
