Description
Technical field
The present invention relates to a kind of new energy-conservation ramp platform thrust slide bearing.
Background technology
Bearing is the important mechanical part for supporting axial workpiece.Mainly it is divided to two kinds of sliding bearing and rolling bearing.It is right
There are following main performance requirements in bearing：Support accuracy, support stiffness, low-friction coefficient and wear-resistant.This requires that bearing is
A kind of very accurate mechanical part, also requires that it has sufficiently large bearing capacity.For the antifriction reached and anti-wear performance, also
Need bearing that there is preferable greasy property.It is developed so far, although bearing technology comparative maturity, but sets up in traditional lubrication
In theoretical foundation.At present, rolling bearing and sliding bearing are respectively applied to different occasions, respectively there is its advantage.Due to the present invention relates to
Be sliding bearing, now existing sliding bearing type and technology are summarized as follows：
From lubrication mechanism, sliding bearing is divided into two kinds of mixed film friction sliding bearing and fluid lubrication sliding bearing.The former
Lubrication is realized by border adsorbed film and hydrodynamic effect, for low speed, underloading and inessential occasion；The latter relies on fluid film
Lubrication is realized, for important events, using more extensive.Fluid lubrication sliding bearing is the main body of sliding bearing, and stream is divided into again
Two kinds of body hydrodynamic lubrication sliding bearing and hydrostatic lubrication sliding bearing.Hydrostatic lubrication sliding bearing is by extraneous hydraulic pressure
System fuel feeding, by oil lift load, is lubricated by hydraulic oil, and the accuracy of manufacture is high, structure is more complicated, cost is higher, is used for
It is required that support stiffness is big, support accuracy is high and large carrying capacity important events.Hydrldynamic pressure lubrication sliding bearing relies on fluid
Dynamic pressure effect realizes lubrication, has the advantages that structure is relatively low compared with simple, cost, better performances, be a kind of application it is more extensive with
Common sliding bearing.It is divided into hydrldynamic pressure lubrication radial plain bearing and hydrldynamic pressure lubrication thrust slide bearing two again
Kind.The former is used to support radial load, and the latter is used to support axial load.Existing main fluid hydrodynamic lubrication thrust introduced below
Sliding bearing type and its feature.
First, clinoplain segmental bearing, this bearing is as shown in Figure 1.It is by between the convergence formed between two surfaces up and down
Hydrodynamic effect is realized in relative motion between gap and the two surfaces, so as to realize lubrication.This bearing has larger carrying energy
Power, there is preferable antifriction and anti-wear performance.
This bearing is divided into two kinds, it is a kind of be upper and lower surface can not around fulcrum fixed bush segment bearing,
It is another be one of surface can around fulcrum tilting pad bearing.Under good design, tilting pad bearing is than solid
Determining segmental bearing has bigger bearing capacity.
2nd, zigzag segmental bearing, this bearing is as shown in Figure 2.Its work and lubrication mechanism a kind of ibid bearing.
Its bearing capacity is more much lower than a kind of upper bearing under the same terms.
3rd, ramp platform segmental bearing, this bearing is as shown in Figure 3.Its work and lubrication mechanism ibid two kinds of bearings.
Its maximum bearing capacity is higher by 20% than the maximum bearing capacity of clinoplain fixed bush segment bearing under identical operating mode.
4th, Rayleigh ladder bearing, this bearing is as shown in Figure 4.Its same spherical bearing of work and lubrication mechanism.Compared to
Above three kinds of bearings, its maximum bearing capacity highest under identical operating mode, than the maximum carrying of clinoplain fixed bush segment bearing

Value, the h that thus method is madeiValue makes bearing load carrying capacity of the present invention up to maximum.
The principle of the invention is described as follows：
It is theoretical according to the interface sliding set up before, in the bearing that the present invention is designed, due on the inclined-plane 3 of inactive plate 1
Interface sliding (reaching that the interface shear strength causes by the interface shear stress) between coating and lubricating oil 5, inactive plate 1
The flow of lubricating oil 5 on inclined-plane 3 between coating and exercise stress 4 further increases, if pressure does not change in bearing, it
Working surface more than uncoated coating on inactive plate 1 is lubricating oil 5 between the flat surface 2 of inactive plate 1 and exercise stress 4
Flow.So, the flow equilibrium condition of the flow of fluid in bearing is just broken.This requires that pressure increases and makes axle in bearing
The flow of lubricating oil 5 for holding inlet region (see Fig. 5) reduces (due to pressure gradient flow), makes bearing outlet area (see Fig. 5) lubrication
Oily 5 flows increase is (due to pressure gradient flow), so that the fluid flow in bearing finally maintains balance (i.e.：Make by axle
The flow of lubricating oil 5 for holding cross section is equal everywhere).So, the coating of setting and by the interface sliding of generation just make this bearing
Bearing capacity be improved.Because coating surface shear strength is low, frictional resistance is small, thus set coating and by generation
Interface sliding on the contrary reduce the coefficient of friction of this bearing so that this bearing have antifriction, energy-conservation, high bearing capacity it is excellent
Point.Here it is the operation principle of this bearing.

Entrance sector width, τsaTo apply the interface shear strength of interlayer on lubricating oil and inactive plate inclined-plane, u is exercise stress relative to quiet
The only movement velocity of plate, ηaFor dynamic viscosity under lubricating oil normal temperature and pressure；
According to formula (4), for different ψ andValue, makes optimal HiValue is Hi,optValue, and then make optimal hiValue, by
This h madeiValue makes the bearing capacity of this kind of new energy-conservation ramp platform thrust slide bearing reach maximum.
