Description
Technical field
The utility model is related to a kind of new thrust bearing shoe valve with heat radiation rack, applied to medium and small dynamic pressure thrust slide bearing.
Background technology
Dynamic pressure thrust slide bearing is mainly used to bear Wa Wengao in larger axial load, operation, tile kilning often occurs and shows
As.It is existing that traditional tile is replaced with water cooling thrust bearing shoe valve, realize that thrust tiling cools, it is to avoid burning accident.Water cooling thrust bearing shoe valve by a watt base,
Cooling tube and babbit layer composition, Wa Ji and babbit layer are connected by wedge mouthful and wedge mouthful groove, a S-shaped water cooling pipe
Watt base is embedded to, is passed through from each arc wedge mouthful trench bottom.Cooling tube is made using copper tube, interior logical cooling water.Babbit layer is produced
Raw heat transfer is quickly taken away heat by cooling water to copper tube, the running temperature of reduction bearing babbit layer, solution
Certainly thrust bearing shoe valve tile kilning problem.But, cooling tube is added in thrust bearing shoe valve, the integral rigidity of thrust bearing shoe valve is influenceed；Medium and small thrust bearing shoe valve by
In the thin unsuitable addition water cooling tube of watt body；S-shaped copper tube manufacture craft requires high, it is necessary to manufacture embedment water cooling pipe in water cooling watt
Square groove complex manufacturing process；Need that cooling water source is provided separately to water cooling watt in work.
The content of the invention
The purpose of this utility model is to overcome weak point in above-mentioned technology to be pushed away there is provided a kind of new with heat radiation rack
Power watt；
The purpose of this utility model can be realized by following technical proposals：A kind of new thrust bearing shoe valve with heat radiation rack by
Babbit layer, heat radiation rack and watt base composition；It is characterized in that the net distribution heat conduction bar of heat radiation rack is arranged in watt base junction flute, and
It is welded on watt base, is embedded between the babbit layer of casting and Wa Ji；The fin of heat radiation rack is distributed in four outside thrust bearing shoe valve
Week；
A kind of new thrust bearing shoe valve with heat radiation rack according to claim 1, its feature heat radiation rack is by netted heat conduction
Bar and surrounding groups of fins into an entity structure, heat radiation rack using aluminum alloy materials manufacture；
A kind of new thrust bearing shoe valve with heat radiation rack according to claim 1, it is characterised in that described structure grooves, be
In a watt base（3）Circumferentially arcuate wedge mouthful groove and radial direction square groove of the upper processing with same depth.
The utility model has compared with prior art to be had the advantage that：
The heat radiation rack of this kind of new thrust tile structure is entity, and the water cooling watt integral rigidity than existing embedment cooling tube is high,
It is more suitable in realizing, the babbit layer of low thrust watt cools；Heat radiation rack, good heat dissipation effect are processed using aluminium alloy；Make work
Skill is simple, without cooling water source is provided separately to thrust bearing shoe valve in work, has saved manufacturing cost and use cost.
Brief description of the drawings
Accompanying drawing 1 is the utility model thrust bearing shoe valve schematic diagram.1 is babbit layer in figure, and 2 be heat radiation rack, and 3 be Wa Ji；
Accompanying drawing 2 is the utility model heat yielding frame structure schematic diagram.
Embodiment
A kind of new thrust bearing shoe valve with heat radiation rack is by babbit layer（1）, heat radiation rack（2）And watt base（3）Composition；Its feature
It is heat radiation rack（2）Netted heat conduction bar be arranged in Wa Ji（3）On structure grooves in, and be welded on Wa Ji（3）On, it is embedded in casting
Babbit layer（1）Under；The fin of heat radiation rack is distributed in surrounding outside thrust bearing shoe valve.Described structure grooves refer in a watt base（3）
The circumferentially arcuate wedge with the same depth mouthful groove and radial direction square groove of upper processing；Described heat radiation rack（2）Netted heat conduction bar weldering
It is connected on Wa Ji（3）On, it is ensured that heat radiation rack（2）Netted heat conduction bar and watt base（3）Contact surface after welding is seamless；In a watt base
Upper babbitting layer（1）, by heat radiation rack（2）Netted heat conduction frame be embedded in babbit layer and Wa Ji（3）Between；Described
The heat radiation rack of new thrust bearing shoe valve（2）For entity structure, therefore, water cooling watt entirety of the new thrust bearing shoe valve than existing addition water cooling tube
Rigidity is high, in being more suitably applied to, the babbit layer cooling of low thrust watt；Described heat radiation rack（2）Manufactured, dissipated with aluminium alloy
Thermal effect is good；The utility model uses and heat radiation rack is embedded in thrust bearing shoe valve（2）Structure replaces existing embedment water cooling tubular construction；Radiating
The manufacturing process of frame, than existing water cooling watt copper pipe bending and build S type square grooves manufacturing process it is simpler, without in work to
Cooling water source is provided separately in thrust bearing shoe valve, has saved manufacturing cost and use cost.
Cool principle：Oil film temperature above thrust bearing shoe valve passes through babbit layer（1）To watt portion's conduction in vivo, cause thrust
Watt internal temperature rises, due to babbit layer（1）With a watt base（3）Material thermal conductivity coefficient it is not high, radiating effect is not good, leads
Cause thrust bearing shoe valve babbit layer（1）Constant temperature is too high, influences bearing lubrication performance.The utility model is in babbit（1）With
Wa Ji（3）Between be embedded with netted aluminium alloy heat conduction frame（2）, because the aluminum alloy heat coefficient of conductivity is high, good heat dissipation effect can be by thrust
Watt babbit layer（1）The heat come is conducted through, passes through heat radiation rack（2）Netted heat conduction bar be diffused into the radiating of watt external surrounding
On piece, fin is by lubricating oil of the heat diffusion into water-cooling groove, so as to reduce babbit layer（1）Temperature improves bearing
Greasy property, it is to avoid the generation of burning accident.
