Description
Technical field
This utility model relates to precision machine tool machining center field, is specifically related to a kind of high-speed electric main shaft bearing.
Background technology
High-speed electric main shaft bearing application scenario needs bearing to have the performance of brilliance.Improve speed ability, strengthen operating essence
Degree, raising system stiffness, reduction heat generation, reduction noise and vibration are several hang-ups that bearing industry faces.Domestic high speed
The bearing existing domestic production manufacture that electro spindle uses also have an import, the bearing temperature rise using domestic production to manufacture is high, makes an uproar
Sound is big, early fatigue peeling phenomenon often occurs, has had a strong impact on the performance of bearing, shortened the service life of bearing.Use
Imported bearing achieves the effect that some are good, but the expensive bearing expense paid every year brings burden to enterprise.
Original structure high-speed electric main shaft Bearing inner design principal parameter falls behind, and has a strong impact on the serviceability of bearing, particularly
Noise is big, and the life-span is short, and precision is low.Therefore, a kind of velocity adaptive at product, stability and durability it are badly in need of in the market
Aspect, it is possible to increase speed ability, enhancing running accuracy, raising system stiffness, reduction heat generation, reduction noise and vibration,
The bearing of good sealing effect.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing capacity strong, and speed ability is high, and rigidity is strong, bearing service life
Extend, the high-speed electric main shaft bearing of good sealing effect.
The purpose of this utility model is achieved in that it includes asymmetric outer ring 1, symmetrical inner ring 2, rolling element 4 and Buddhist nun
Dragon retainer 3, electro spindle housing accessory installation in asymmetric outer ring 1 coordinates, and symmetrical inner ring 2 is installed with electro spindle axle and is combined together
Receiving portion divides axial force, nylon cages to be guided on side, asymmetric outer ring, and rolling element 4 is arranged on asymmetric outer ring 1, symmetrical inner ring
Between 2 and nylon cages 3, being provided with the slope of 45° angle bottom nylon cages 3, the internal diameter pocket hole of nylon cages 3 is provided with
For 45 ° of boss rank of lock ball, the straight hole that the external diameter pocket mouth of nylon cages 3 assembles for ease of rolling element and retainer.
This utility model global design principal parameter is all based on recent design theory, and international joint, can be with Germany
GMN, Japan NSK, the like product of SKF Company of Sweden compare favourably；Symmetrical inner ring, asymmetric outer ring use high-quality bearing
Steel, rolling element number is many, and carrying lotus is big, retainer novel structure, containing bag rolling element high speed rotating, polyether-ether-ketone crystallization high-performance material
Material, high wear resistance, the slip splendid due to it and the characteristic of minimizing abrasion so that it is still can run when severe；By
Low friction and more favourable tribology, the lower running temperature brought；The lubrication grease supplying formed in nylon cages pocket hole
Deposit, lasting offer lubrication；Longer service life；Increase cost benefit.Limit revolution is high, has low vibration, low noise, rotation
Turning precision high, the advantage such as rub little.Use special thermal treatment technique.
Nylon cages material partially crystallizable high performance plastics, polyether-ether-ketone (PEEK), the carbon fiber of enhancing；The fortune allowed
250 ° of C of trip temperature, nylon cages is guided on side, outer ring；Injection mo(u)lding；The retainer optimized for grease lubrication, low friction system
Number, reduces and gets rid of the vibration of nylon cages, the machinery of brilliance, chemically and thermally stability；Reduce the operating temperature of 10%,
Extend the service life of 30%.Substantially increase limit revolution；All technical reaches international standards, and instead of import.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is nylon holding frame structure schematic diagram；
Fig. 3 is the A-A schematic diagram of Fig. 2.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
In conjunction with Fig. 1, the present embodiment includes asymmetric outer ring 1, symmetrical inner ring 2, rolling element 4 and nylon cages 3, asymmetric
Outer ring 1 electro spindle housing accessory is installed and is coordinated, and symmetrical inner ring 2 is installed with electro spindle axle and is combined together receiving portion point axial force,
Rolling element 4 is arranged on asymmetric outer ring 1, between symmetrical inner ring 2 and nylon cages 3, is provided with 45° angle bottom nylon cages 3
Slope, the internal diameter pocket hole of nylon cages 3 is provided with 45 ° of boss rank for lock ball, and the external diameter pocket mouth of nylon cages 3 is
It is easy to rolling element and the straight hole of retainer assembling.
In conjunction with Fig. 2-3, the present embodiment high-speed electric main shaft bearing is for the electro spindle of machining center, the electro spindle axle of standard
Holding, asymmetric outer ring uses dissymmetrical structure design, can bear axial load or radial load (limiting the load on a direction)；
Symmetrical inner ring can divide axial force with receiving portion；Grade of tolerance P4, P2 ensure running accuracy, and the seating time is short；Chamfering optimization is easy to
Install；Meet ISO19 and ISO10 dimension series standard and have compact cross-sectional area.Inside and outside lasso is manufactured with high-quality bearing steel,
Extend the service life of bearing, 2 times of deep groove ball bearing can be reached service life, there is preferable corrosion resistance；Directly
Oil lubrication modification, can reduce maintenance；Due to its frictional behavior and lower mass force, the speeds comparable deep groove ball bearing of this bearing
Speed increase up to 30%, properties of materials improves rigidity axially and radially, and it brings the advantage that and adds accurately
Property, and the change of critical resonance.Bigger bearing rigidity, the thermal expansion of reduction and relatively low vibration, can realize adding of maximum
Work precision.The high resistance to temperature fluctuation brought by big bearing radial gap, minimum friction the low operating temperature brought.
And have employed special Technology for Heating Processing.
