Background technique
The host of sliding-vane air compressor is made of rotor and stator, is wherein uniformly provided on rotor several longitudinal
Sliding slot, slide plate are free to slide in sliding slot；Stator is a cylinder, and rotor is eccentric in the stator to be placed, when the rotor rotates, sliding
Piece is thrown out of in sliding slot under the influence of centrifugal force and is in close contact with stator by oil film, in two neighboring slide plate and stator
A closed air chamber, as air compression chamber are formed between wall, when rotor rotates, the volume of air compression chamber is with slide plate cunning
The size of output and change, in breathing process, air is inhaled into compression chamber via filter, and with the lubrication that sprays into host
Oil mixing, in compression process, the volume of compression chamber is gradually reduced, and pressure gradually rises, and gas mixture passes through exhaust later
Mouth discharge.It is all to adopt to be sealed with the end cover between existing sliding-vane air compressor cylinder block and front and rear cover, front end
It is sealed between lid and axle envelope using oil sealing, existing sealing structure is complex, seals higher cost.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of sliding-vane air that structure simple seal effect is good compression
Machine.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that: sliding-vane air compressor, comprising: make
For the cylinder block of stator, the rotor in cylinder block is set, several sliding slots are evenly arranged on the middle part of the rotor,
Slide plate sliding be provided with in its mutually matched sliding slot, the axle journal before the front end of the rotor is provided with, in the rotor
Rear end is provided with rear shaft neck, the front end of the cylinder block is provided with drive end bearing bracket and axle envelope, in the rear end of the cylinder block
It is provided with rear end cap, drive end bearing bracket axis hole is provided in the middle part of the drive end bearing bracket, is provided with rear end in the middle part of the rear end cap
The preceding axle journal of lid axis hole, the rotor front end is arranged in drive end bearing bracket axis hole by preceding bearing shell, the rear shaft neck of the rotor rear end
It is arranged in rear end cap axis hole by rear bearing shell, drive end bearing bracket sealing is provided between the front end and drive end bearing bracket of the cylinder block
O-ring is provided with rear end cap seal O-ring between the rear end and rear end cap of the cylinder block, in the drive end bearing bracket and axis
Axle envelope O-ring is provided between envelope.
The invention has the advantages that above-mentioned sliding-vane air compressor, between cylinder block and front and rear cover, drive end bearing bracket and axis
O-ring sealing is all made of between envelope, structure is simple, and sealing effect is good, and it is easy to maintenance, make O-ring in sliding-vane air compressor
On applied well, reduce air compressor shaft end seal cost.
