Description
Technical field
The utility model is related to a kind of bearing, more particularly, to a kind of automobile oilless air compressor bearing.
Background technology
Requirement with people to environment is increasingly paid close attention to, as the oil-free vortex air compressor in compressor, due to
With following special：1) pollution without oil/carbon, service life is long；2) moving component is few, simple in construction, and reliability is high；3) work
Move fixed scroll when making not contact, vibrating noise is small.Therefore oil-free vortex air compressor application is more and more extensive.
The plane motion of oil-free vortex air compressor fixed scroll and movable orbiting scroll minor radius in the case where certain phase is kept, is moved
Fixed scroll engages to form some compression chambers to crescent moon Shape closed, the pressure of crescent that the gas of suction working chamber is subsequently formed
Contracting chamber is gradually reduced, and then quiet disk center position exhaust outlet is discharged again.
In order to ensure more preferable closed compression chamber, fixed scroll and movable orbiting scroll axial gap and axial stability are very crucial,
It is in existing market to use deep groove ball bearing more, because the bearing axially has certain shifting amount, when empty without compression in compression chamber
During gas, bearing is solely subjected to the gravity of movable orbiting scroll itself, and when compression chamber compressed air, movable orbiting scroll is caused to axle by air pressure
Bear big axial load.
Therefore bearing is to need to bear larger axial load and minimum axial movement value in normal work, existing
Bearing due to the control ability without larger axial carrying capacity and axial movement value, therefore cause equipment compression effect
Rate is low, and noise, while bearing also easily produces failure.
Utility model content
The purpose of this utility model is exactly the defect in order to overcome above-mentioned prior art presence and provides a kind of automobile oil-free
Bearing used for air compressor.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of automobile oilless air compressor bearing, including two sets of angular contact ball bearing bodies, two sets of angular contact ball bearings
Body is using face-to-face or back-to-back setting, and described bearing both sides set sealing ring, inside filling lubricator.
Often set angular contact ball bearing body includes outer ring, inner ring, steel ball and retainer, and described steel ball is located at outer ring raceway
It is interior, it is uniformly divided on whole raceway groove by retainer, inner ring is located at steel ball inside circumference, described sealing ring is relative with outer ring
It is fixed, rotated against with inner ring.
Described sealing ring is located at outer ring both sides.
Described angular contact ball bearing body is using 40 degree of contact angles.
Described outer ring and/or inner ring are provided with rib.
Described lubricator is lubricating grease, full of whole Bearing inner.
Described outer ring and inner ring is the part after high tempering processing.
Described sealing ring is ACM rubber.
Described retainer uses the part that PA46 materials are made.
Described described lubricating grease uses KYODO ETK.
Compared with prior art, the utility model has advantages below：
1st, when being full of pressure in compression chamber, bearing needs to bear larger axial compressive force, designs and realizes by using rib
Contact angle is 40 degree, it is ensured that the axial force can completely be born by bearing, realize bearing reliability and long-life.
2nd, bearing is controlled axial movement value, is realized the stable type of movable orbiting scroll using two sets of back-to-back and face-to-face configurations,
Reduce noise.
3rd, Bearing inner is full of lubricating grease, and designs sealing ring in the both sides of two sets of bearings respectively, realizes lifelong profit
It is sliding.
4th, lasso uses high tempering, and sealing ring uses ACM rubber, and grease uses KYODO ETK, and retainer uses PA46
Material, realizes bearing and still keeps stronger service behaviour under the high temperature conditions.
