The purpose of lubrication is that appropriate oil film is maintained between slip or rolling friction pair part, and oil film must be enough to make friction
It is smaller and prevent parts depreciation, while cooling effect is played to friction member, to exclude the heat that friction is produced.From the structure of spindle
See, the upper bearing (metal) of spindle is usually inner ringless roller bearing, and lower bearing is that small sphere of exterior rearview (sharp ingot butt) or section cambered surface (flat ingot butt) are sliding
Moving axis bearing structure.The lubricating system of lower bearing is bath lubrication；The lubricating system of upper bearing (metal) is film lubrication, and its lubricant effect takes
It is interval to over-lubrication in serious oil starvation successively certainly in the level height of lubricating oil, be subdivided into dry friction (serious oil starvation state),
In semi-dry friction (oil starvation state), boundary lubrication and mixed lubrication mode, dry friction is in unlubricated state.
It is generally acknowledged that the Mechanism of oil supply of spindle upper bearing (metal) lubricating oil is：During one is spindle revolution at a high speed, spindle blade surface lubrication
Oily centrifugal force and spindle blade oscillation crosswise agitation spindle inner chamber lubricating oil formation spindle intracavitary mist of oil, two when being spindle revolution at a high speed,
The excessive castering action of the class siphon lifting of poppet surface and oil film along the conical surface under spindle blade under spindle blade, in spindle blade bearing rib formation oil film
And be transferred between roller bearing inner ring and retainer, form the Condition of Thin Film Lubrication of spindle upper bearing (metal).
Certain friction is always had in rolling bearing work, for spindle upper bearing (metal), is shown in roller and bearing
Ring, roller and retainer, the friction between roller and spindle blade bearing rib, due to spindle short time oil starvation, can cause upper bearing (metal) half-dried
Friction and dry friction operation, the softer retainer material of harder roller material plow cause the metal of retainer material by one
Transfer from individual surface to another surface.The result that this material is persistently shifted necessarily causes the abrasion of retainer window to become big, most
After cause bearing wear spindle fail；In addition, bobbin oil constitutes oil damping vibration damping with the absorbing wind spring in spindle inner chamber, drop is played
The effect of low vibration amplitude of spindle, if the serious oil starvation of spindle, can increase vibration amplitude of spindle influence spindle spinning performance.Therefore, it is general to spin
A bobbin oil can be mended in three months by knitting enterprise, and managing the enterprise of difference even must mend a bobbin oil for one month.
The mode of bobbin oil loss is divided into normal loss and abnormal waste, and normal loss is operated from spindle through long-term,
Spindle oil degradation, physical and chemical index decline, the increase of spindle oil viscosity, cause the thermal losses that oil level declines and spindle temperature rise is caused；
Structure design of the abnormal waste from spindle：The lubricating system of the spindle upper bearing (metal) of prior art moistens for open mist of oil film
Sliding, on the one hand open mist of oil filmlubrication have lubricated spindle upper bearing (metal) and spindle blade, the need for meeting spindle upper bearing (metal) lubrication.Separately
On the one hand due to opening, cause bobbin oil evaporated into the way of mist of oil in air cause loss.It is reduced or avoided improper
Loss is the key of solution spindle fuel-saving technique in spindle structure design.
From separate type tip spindle, elastic tube-type tip spindle, the flat ingot butt spindle of elastic tube-type, the elasticity with axial buffer
From the point of view of the structure design of tubular type tip spindle and aluminum casing spindle etc., its upper bearing (metal), bearing washer and Rotor Systems spindle blade
Between be Open architecture, not using any Sealing Technology.Separately from the point of view of spindle practical application, spindle actual speed is higher,
From 16000rpm-25000rpm, and almost class Three's operating in month after month 24 hours throughout the year, any contact seal technology is uneconomical
With it is incompetent.Therefore, the bobbin oil in spindle inner chamber and spindle exterior space insertion, spindle inner chamber be in nature atomization,
In consumption.
From a kind of oil-saving spindle structure design with patented technology, the seal groove that its bearing seal is covered is interior
Annular groove under the concave of hole, does not install other sealing mediums additional, and bearing seal cover coordinates with spindle blade for larger gap, spindle blade
Itself runs at high speed, and is climbed upwards along spindle blade surface at the bearing seal cover static with respect to bolster and in the absence of prevention lubricating oil
Mechanism, therefore the structure can not implement effective sealing function, lubricating oil still can upwards climb simultaneously along the spindle blade surface at upper bearing (metal)
With spindle exterior space insertion.Substantially still it is between its upper bearing (metal), bearing seal cover, seal groove and Rotor Systems spindle blade
Open architecture, not using any Sealing Technology, its actual oil-saving effect is unsatisfactory.
