Bearing structure of a water lubricated compressor

Abstract

The invention discloses a bearing structure of a water lubrication compressor. The bearing structure comprises a shell. The shell comprises a suction-side bearing block and an exhaust-side bearing block. A female rotor is sleeved with a female rotor suction-side water lubrication radial sliding bearing and a female rotor exhaust-side water lubrication radial sliding bearing. Thrust bearings are located on the sides, located at the suction-side bearing block, of a male rotor and the female rotor. Each thrust bearing comprises a top plate and a bottom plate, wherein the top plate is connected with the male rotor and the female rotor; bearing rollers are arranged between the bottom plate and the top plate; the two sides of each bearing roller are provided with balance bars. Through the designon the thrust bearings of the male rotor and the female rotor, especially the balance bars of the bearing rollers, the bearing rollers can be conveniently mounted and can run more balanced through centrifugal force during operation of the bearings, and abrasion caused by movement can be reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a bearing structure of a water-lubricated compressor. Background technique [0002] The existing oil-free water-lubricated twin-screw compressors are prone to wear in practice because the bearing part bears a large axial force, especially the wear of the inner rollers. Not only the wear of the bearing will affect the working effect, but also the wear debris will The lubricating water causes wear on other components. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a bearing structure of a water-lubricated compressor. The technical solution adopted by the present invention to solve its technical problems is: [0004] A bearing structure for a water-lubricated compressor, comprising a casing, the casing includes a suction-side bearing seat and a discharge-side bearing seat, a male rotor and a female ro...
