Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a bearing structure of a water lubrication compressor. The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides a bearing structure of water lubricated compressor, includes the shell, the shell includes suction side bearing, exhaust side bearing, the shell embeds there is positive rotor, cloudy rotor, wherein the cover is equipped with positive rotor suction side water lubricated journal bearing, positive rotor exhaust side water lubricated journal bearing on the positive rotor, the cover is equipped with cloudy rotor suction side water lubricated journal bearing, cloudy rotor exhaust side water lubricated journal bearing on the cloudy rotor, positive rotor, cloudy rotor are located suction side bearing one side and all are provided with thrust bearing, thrust bearing includes roof, bottom plate, wherein the roof is connected with positive rotor, cloudy rotor respectively, be provided with bearing roller between bottom plate and the roof, bearing roller both sides are provided with the balancing pole.
Preferably, the thrust bearings of the male rotor and the female rotor are offset from each other.
And the bottom plate is provided with a water through hole corresponding to the balance rod.
Preferably, the thrust bearing is provided with gap adjusting gaskets at one side facing the inner wall of the air suction side bearing seat.
The invention has the beneficial effects that: through the design of thrust bearings of the male rotor and the female rotor, particularly the balance rods of the bearing rollers, the roller mounting can be facilitated, and the bearing rollers can run more balance by utilizing centrifugal force when the bearing works, so that the abrasion caused by the play can be reduced.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a perspective view of the present invention;
