Design.But they generally all there are it is complex in structure or technique the shortcomings that, the circulation of lubricating oil cannot reach optimal,
Reducing on bearing temperature still has the defects of certain, cannot still be met the requirements for the environment of high speed, high vibration.
Utility model content
The purpose of this utility model, it is intended to the shortcomings that overcoming the prior art, solves fever and the problem of temperature rise of sliding bearing,
There is provided it is a kind of have it is simple in structure, it is easy to use, can effectively accelerate the circulation of lubricating oil, reduce the fever of bearing, reduce bearing
Temperature rise, makes the novel high speed hydrodynamic sliding bearing for the advantages that it is applied in high speed, high antivibration rotating machinery.
To achieve the above object, the utility model adopts the following technical solution：
A kind of herringbone circular helicoid hydrodynamic sliding bearing, it is characterized in that, including bearing body, along bearing body inner wall
Circumferencial direction is equipped with the herringbone circular helicoid that at least one depression is formed, for forming bearing lubrication oil pocket；In herringbone
Oil inlet is equipped with the top arc maximum cutting-in of circular helicoid, in the bottom of herringbone circular helicoid close to bearing both ends
At the circular arc maximum cutting-in in face, oil outlet is respectively equipped with.
Further, when the setting of herringbone circular helicoid is multiple, multiple herringbone circular helicoids are in bearing body
It is uniformly arranged on wall along the circumferencial direction of bearing body.
Further, the oil inlet of multiple herringbone circular helicoids is located on same circle.
Further, the oil outlet positioned at bearing body the same side is located on same circle.
Further, novel high speed hydrodynamic sliding bearing is applied on high-speed machine tool axis system.
Further, novel high speed hydrodynamic sliding bearing is applied on high-speed rotor system.
The specific course of work is as follows：
During bearing working, for the lubricating oil from oil inlet into bearing under the drive of shaft, what is along the circumferential direction flowed is same
When, it is as shown below along spiral arc surface current to bearing end.Oil film pressure is formed on convergent arc surface, realizes carrying.
The presence of spiral circle cambered surface, accelerates the axial flowing of lubricating oil, accelerates lubrication oil circulation, this is reduce bearing temperature rise one
A reason.Due to the setting of oil outlet, oil inlet is set to form a press belt to oil outlet, the deep fat that last oil film wedge gets off enters
Pressure gradually reduces during the arc surface of diverging, they be difficult by entering next oil film wedge into and out of the press belt between hydraulic fluid port, this
The Repeat-heating of deep fat is avoided, this is another reason for this bearing temperature rise is low.So this bearing has well
High speed characteristics.
The beneficial effects of the utility model are：
The utility model, with reference to actual application background, provides a kind of brand-new oil pocket with reference to existing sliding bearing structure
Structure-- bicircular arcs herringbone spiral oil wedge；On the bearing internal circular surfaces of the utility model, multiple herringbone circular arcs are machined with
Helicoid, is equipped with oil inlet, in lambdoid bottom close to bearing both ends of the surface at lambdoid top arc maximum cutting-in
At circular arc maximum cutting-in, oil outlet is respectively equipped with；The circulation of lubricating oil can effectively be accelerated, reduce the fever of bearing, reduce bearing
Temperature rise.
