The invention discloses a kind of novel bearing for belonging to field of bearings, i.e., a kind of novel more sliding layer self-lubricating plain bearings.More sliding layer sliding bearings are made of two or more sliding shaft sleeves.Compared with traditional sliding bearing, this more sliding layer sliding bearing can be competent at the application of higher revolving speed occasion.
Description
Technical field
The present invention relates to a kind of novel bearing for belonging to field of bearings, i.e., a kind of novel more sliding layer sliding bearings.
Background technique
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is to support mechanical rotary body, is reduced
Coefficient of friction in its motion process, and guarantee its rotating accuracy.According to the difference of the friction properties of the moving elements, bearing can be divided into rolling
Dynamic bearing and sliding bearing two major classes.Sliding bearing advantage includes stable working, and carrying pressure is big, and axis handling are particularly easy to, but
Frictional resistance is relatively large, be not suitable for it is oil-free under the conditions of run at high speed.At many mechanical positions needed with high revolving speed bearing,
For example high-speed bearing testing machine, equipment gearbox, transmission shaft etc., traditional sliding bearing can not be competent at high-revolving requirement.
Summary of the invention
A kind of novel more sliding layer sliding bearings of the present invention, solve above-mentioned conventional slip bearing can not be competent at it is higher
The problem of revolving speed is applied.More sliding layer sliding bearings are made of two or more sliding shaft sleeves.
In the case where being made of two sliding shaft sleeves of size, the internal diameter of small sliding shaft sleeve covers on axis, occurs with axis
It works with respect to sliding friction, the internal diameter of the outer diameter and big sliding shaft sleeve of the small sliding shaft sleeve matches, big sliding axle
It covers and occurs to work with respect to sliding friction with the outer diameter of small sliding shaft sleeve, the outer diameter of big sliding shaft sleeve is then fixed on bearing block
On.It can yet another metal cage ring between size sliding shaft sleeve to improve precision.The internal diameter of the metal cage ring and small
The outer diameter of sliding shaft sleeve matches and its combination can guarantee and mutual vibration does not occur, the outer diameter of the metal cage ring and big cunning
The internal diameter of moving axis set matches, and the outer diameter of big sliding shaft sleeve and the metal cage ring occurs to work with respect to sliding friction.For
The suitable axial movement for preventing small sliding shaft sleeve and metal cage ring from may occur when rotated, can install in shaft in the application
Spring is pressed from both sides, or retaining ring is installed on big sliding shaft sleeve or bearing block.The inner surface of retaining ring can have self-lubricating function.This pair is sliding
The rotation speed of dynamic layer sliding bearing is the sliding speed of two sliding layers(That is, the rotation speed of axis and small sliding shaft sleeve)It
With.
In the case where being made of large, medium and small three sliding shaft sleeves, the internal diameter of small sliding shaft sleeve covers on axis, occurs with axis
Work with respect to sliding friction, the outer diameter of the small sliding shaft sleeve and the internal diameter of middle sliding shaft sleeve match, middle sliding shaft sleeve with it is small
The outer diameter generation of sliding shaft sleeve works with respect to sliding friction, the internal diameter phase of the outer diameter of sliding shaft sleeve and big sliding shaft sleeve in this
Match, and the generation of the outer diameter of sliding shaft sleeve of the big sliding shaft sleeve in works with respect to sliding friction, and the outer diameter of big sliding shaft sleeve is then solid
It is scheduled on bearing block.To improve precision, as the case where above-mentioned two sliding layer bearings composition, in medium and small sliding shaft sleeve
Between and big-and-middle sliding shaft sleeve between can respectively have a metal cage ring again.To prevent small sliding shaft sleeve and its metal cage ring
And the suitable axial movement that middle sliding shaft sleeve and its metal cage ring may occur when rotated, in big sliding shaft sleeve or bearing block
It is above mountable to prevent axial moving device such as retaining ring.The inner surface of retaining ring can have self-lubricating function.Three sliding layer sliding
The rotation speed of bearing is three sliding layer sliding speeds(That is, axis, the rotation speed of small sliding shaft sleeve and middle sliding shaft sleeve)It
With.
The case where more than three sliding shaft sleeve forms and so on.In the case where multiple sliding shaft sleeves composition, rotation
Speed is reachable to be several times as much as conventional slip bearing.So this more sliding layer sliding bearing can be competent at more high-revolving application.
Detailed description of the invention
By taking double sliding layer sliding bearings as an example, respectively illustrates no retaining ring and have the structure of retaining ring, and illustrate several shapes
The retaining ring of formula.
Attached drawing 1 is without retaining ring and has double sliding layer sliding bearing schematic diagrames of retaining ring and the example of some retaining rings.
