Description
Technical field
The utility model relates to Compressor Technology fields, and in particular to a kind of water lubrication shaft for single screw compressor
It holds.
Background technique
Single screw compressor forms Meshing Pair by a cylindrical screw and two planar gaterotors being arranged symmetrically, and is mounted in casing
It is interior.Screw channel, casing inner wall and star-wheel tooth constitute enclosed volume.Power passes on screw shaft, drives star-wheel rotation by screw rod,
Gas is entered in screw channel by suction chamber, is discharged after compression by vent ports and discharge chamber.Wherein, bearing is single screw rod compression
The important fundamental parts of machine can guarantee that screw rod being capable of high speed rotation.What single screw compressor mostly used at present is steel bearing,
But steel bearing, since the restriction of its material, the performances such as high temperature resistant, corrosion-resistant are short of, application range receives limitation, in addition,
Mechanical seal must be arranged between medium and bearing using steel bearing prevents medium to separate medium and bearing
Pollution bearing oil leads to lubrication failure.
Utility model content
The purpose of this utility model is exactly to provide a kind of for single spiral shell to overcome the problems of the above-mentioned prior art
The water lubriucated bearing of bar compressor.
The purpose of this utility model can be achieved through the following technical solutions: a kind of water profit for single screw compressor
Plain besring, the bearing include bearing body, the internal gland and outer press cover that bearing body two sides are arranged in, and the bearing body includes
Outer ring, inner ring, the retainer being arranged between inner ring and outer ring and the ball being filled in retainer, the material of the ball
For the silicon nitride material Jing Guo laser treatment.In use, bearing block is set in the end of single-screw compressor housing, it then will be interior
Gland, bearing body, outer press cover are sequentially sleeved on the main shaft of single screw compressor, wherein internal gland and outer press cover clamp shaft
Ontology is held, and is fixed with bearing block.The ball of the utility model bearing body uses silicon nitride ceramic material, and passes through laser table
Surface treatment, hardness should reach HV1700, and will not be corroded, long service life.
Preferably, the outer press cover is equipped with water inlet, the water inlet face ball.The utility model uses water
It is lubricated, the heat in bearing can also be removed in time.
The internal gland is equipped with drainage hole, and drainage hole is arranged, the water in bearing body can be immediately discharged to single spiral shell
In the housing chamber of bar compressor, do not need that mechanical seal is installed on main shaft, and compressed air and compression case will not be polluted
Body cavity can make can have enough water to carry out in bearing body in this way moreover, the diameter of drainage hole is less than the diameter of water inlet
Lubrication, and this part water energy enough plays the role of sealing.
The inner wall of the internal gland is equipped with dustproof cover, i.e. dustproof cover is contacted with the main shaft of single screw compressor, can be prevented
Solid impurity in housing chamber enters bearing.
The inner ring and outer ring uses martensitic stain less steel, and hardness should reach HRC60-65.
The retainer uses PEEK material.
Compared with prior art, the beneficial effects of the utility model are embodied in:
(1) use silicon nitride ceramic material as ball, hardness is high and rotproofness is good, bearing long service life；
(2) water lubrication is used, without installing expensive mechanical seal, machine construction is simplified, shortens major axis size, mention
High machine operational reliability, has saved cost.
Detailed description of the invention
Fig. 1 is the mounting structure schematic diagram of the utility model；
Fig. 2 is the side view of the utility model bearing body.
Wherein, 1 is shell, and 11 be housing chamber, and 2 be bearing block, and 3 be internal gland, and 31 be drainage hole, and 4 be outer press cover, and 41 are
Water inlet, 5 be bearing body, and 51 be outer ring, and 52 be ball, and 53 be inner ring, and 54 be retainer, and 6 be main shaft, and 7 be dustproof cover.
