Specific embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail, but does not limit the utility model.
The utility model provides the tilting thrust bearing that a kind of Changeable elastic modulus cushion is supported, and its structure is as schemed
Shown in 1, mainly it is made up of thrust disc 1, tiling material layer 2, cushion 3, support ring 4, wherein：Tiling material layer 2 and cushion 3
Bond together, collectively constitute thrust bearing shoe valve, the tiling entrance side 8 of the thrust bearing shoe valve is machined with chamfering；Cushion 3 circumferentially has gradually
Changeable elastic modulus, its entrance while 8 elastic modelling quantity less than its export while 9 elastic modelling quantity, entrance while 8 to outlet while 9 springforms
The linear increase of amount, cushion 3 is bonded in the fan groove 5 of support ring 4 with strength waterproof glue (such as epoxide-resin glue).
The thrust disc 1 is prior art, is that one kind is processed by bronze, be may be installed in rotary shaft, with certain
The rotatable part of axial force load plane.
The structure of the support ring 4 is as shown in Fig. 2 ring upper surface is machined with equidistant fan groove 5.The cylindrical place of fan groove 5
The flange 6 for preventing rubber blanket from moving radially is left, is machined between fan groove 5 for the bolt hole of installation locking support ring
7。
Respectively as shown in Fig. 3 Fig. 4, both have equal central angle to the structure of the tiling material layer 2 and cushion 3, circle
Angular radius is 1mm (or according to depending on actual conditions)；Tiling material layer and cushion all have uniform thickness, i.e. tiling material layer
It is parallel with cushion upper and lower surface；Both are rounded down on the vertical side of surrounding.Tiling material layer 2 is machined with chamfering on entrance side 8,
Chamfer angle is 5 ° (or according to depending on actual conditions), and so that lubricating fluid is entered between tiling and thrust disc hydrodynamic profit is formed
It is sliding.Tiling material layer 2 and cushion 3 are bonded together with super glue (such as epoxy resin glue), form thrust bearing shoe valve, and bonding is complete
Cheng Houxu measures the total height of each thrust bearing shoe valve, for each thrust bearing shoe valve on a thrust bearing；Each thrust bearing shoe valve
Total height error must be in prescribed limit (for example：No more than 20 μm), tiling material layer 2 that otherwise will be big to the total height is carried out
Secondary machine, to ensure the highly consistent of each thrust bearing shoe valve.
The tiling material layer 2 is macromolecular material, can need to be screened according to working environment and condition, for example, select
Select the materials such as match dragon, flying dragon or the more preferable SF-1 of other anti-wear performances.
The thrust disc 1 and support ring 4 are stainless steel material.
The performance design of the cushion 3 is mainly elastic modelling quantity, hardness and intensity and sets, to work as the utility model thrust
When bearing application seawater does lubricant, should have preferable anti-seawater corrosion, impact resistance, creep-resistant property and longer use longevity
Life.
The tiling material layer 2 and cushion 3 are superimposed and are bonded together into after thrust bearing shoe valve, and it passes through bonding way and consolidates
Surely arrive in the fan groove 5 of support ring 4, can so make it completely restrained in axial direction, circumference and the radial direction free degree, will not bad student's cunning
It is dynamic.Now because cushion 3 is squeezed, thrust bearing shoe valve height may change, and must measure the flatness of all tilings, it is ensured that
Flatness must grind highly big watt in error allowed band, otherwise, until all tilings are highly consistent.
The above-mentioned tilting thrust bearing (abbreviation thrust bearing) that the utility model is provided, its course of work is as follows：
When rotated, lubricant is brought between thrust disc 1 and thrust tiling the thrust disc 1 of thrust bearing by thrust disc 1
Gap in, and film pressure distribution is set up in gap, form the liquid film power contrary with loading direction.Liquid film power forces elasticity
Pad deformation, but due to cushion 3, circumferentially elastic modelling quantity is different, thus deform size difference, the little entrance of elastic modelling quantity
The deformation of the side of side 8 is big, causes the thrust bearing shoe valve bonding with its towards the run-off the straight of entrance side 9, makes between thrust disc 1 and thrust tiling
Key groove is formed, beneficial to forming hydrldynamic pressure lubrication.When liquid film power is equal with load, the inclination angle of thrust tiling and liquid film pressure
Power distribution determination, makes thrust bearing working stability.When operating mode (rotating speed or load) changes, film pressure, thickness of liquid film, elasticity
Pad deformation, the inclination angle of thrust bearing shoe valve cover material layer change, and make liquid film power and load reach balance again, into new steady
Determine working condition.When thrust bearing works, cushion 3 can absorb and be delivered to the vibration on damp type tilting bush component through liquid film
Energy, plays the effect of vibration damping and vibration isolation.And cushion 3 and tiling material layer 2 and support ring 4 bond together entirely, its bottom does not have
There is exceptional space, in water lubrication environment, do not have the impurity such as silt into thrust bearing shoe valve bottom, make thrust bearing functional reliability
Improve.
