Description
Technical field
The present invention relates to a kind of machining equipment, more particularly to a kind of oil-air lubrication spacer component.
Background technology
At present, with the arriving in full-automatic epoch, automation processing part will necessarily cover broader field, various
Change high rigidity, the material of high intensity can gradually be applied to carving, milling and grinding field.Therefore, high-accuracy electro spindle will necessarily be in machine
Bed manufacture field occupies important position.
Electro spindle includes bearing block, bearing and shaft core, and bearing is arranged inside bearing block, bearing mainly by outer ring, inner ring,
Rolling element three parts form, and inner ring is located in outer ring, raceway is formed between outer ring and inner ring, rolling element is in raceway
Roll, shaft core is pivoted by bearing and bearing block to be coordinated.It is identical and the lubrication of bearing is generally divided into grease lubrication and oil-air lubrication
The bearing of structure model, oil-air lubrication can reach higher rotating speed and efficiency than grease lubrication.The oil gas of existing electro spindle
Lubrication generally by opening up lubrication channel on bearing block, so as to by oil-gas jetting on bearing, in order to relatively evenly lubricate,
Such oil-air lubrication structure needs to open up more lubrication channel, so, not only makes the difficulty of processing larger and more
The space that lubrication channel takes is larger, is not suitable for the more compact electro spindle of structure.
But there is following defect in existing electro spindle Oil Gas Lubrication Technology：
(1) lubrication oil gas, which has oil return gas circuit between spacer component and bearing block and enters oil and gas path, interferes infiltration now
As causing to lubricate oil gas smoothly to enter in lower bearing raceway, and the heating that can not effectively solve bearing is too high, operating efficiency
The problem of relatively low.
(2) existing electro spindle oil-air lubrication is usually that lubrication channel is opened up on bearing block by oil-gas jetting in bearing
On.And in this case, when lubrication oil gas sprays into bearing by spacer component, oil gas changes in flow rate is larger, and fuel delivery is neglected height and neglected
It is low, cause uneven oil spout, lubrication and the bad phenomenon of cooling effect to occur.
The content of the invention
, can be effective it is an object of the invention to provide oil-air lubrication spacer component for overcome the deficiencies in the prior art
The heating of bearing is reduced, improves operating efficiency, uneven oil spout, lubrication and the bad phenomenon of cooling effect can be avoided to occur.
The purpose of the present invention adopts the following technical scheme that realization：
