Description
Technical field
The utility model is related to a kind of hydraulic turbine, particularly a kind of self-lubricating guide vanes of water turbine bearing.
Background technology
At present, existing guide vanes of water turbine bearing includes bearing body, and its anti-wear performance and greasy property are poor, machinery
Low intensity, bearing capacity is low, and coefficient of friction is big, operationally, need to often inject lubricant, the machine for bearing high load
The problem of often there are lubricating difficulties or can not lubricate in tool equipment, simultaneously as being lubricated between axle and bearing not good can cause friction
Heating rises operating temperature, and when shutting down, due to directly being contacted between friction pair metal, therefore the resistance reset is very
Greatly.
Utility model content
Main purpose of the present utility model be the shortcoming for overcoming prior art there is provided a kind of achievable self-lubricating, with good
Good anti-wear performance and greasy property, coefficient of friction are small, high mechanical strength, and bearing capacity is strong, and can avoid due to axle and bearing
Between lubricate it is not good cause frictional heating operating temperature is risen problem, reduce the guide vanes of water turbine of resistance reset when shutting down
Bearing.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of self-lubricating guide vanes of water turbine bearing, bag
Include bearing body, it is characterised in that：The bearing body includes metallic base layer, porous intermediate layer and solid lubricant layer,
The metallic base layer, porous intermediate layer and solid lubricant layer ecto-entad are combined as a whole successively, the solid lubrication layer surface
It is provided with multiple equally distributed holes, hole and is inlaid with solid stick, and solid lubrication layer surface is provided with one layer of solid
Lubricating film.
Further, metallic base layer outer surface also incorporates coating for protection against corrosion.
Further, porous intermediate layer is formed by sintered, spherical bronze powder.
Further, hole is the through hole or blind hole for being arranged at solid lubrication layer surface.
Further, solid stick is made of modified plastics.
Further, solid lubricant film is formed by the kollag for being coated on solid stick surface.
From above-mentioned to description of the present utility model, compared with prior art, the beneficial effects of the utility model are：It is logical
Cross and multiple equally distributed holes are set on bearing body, and the inlaid solid lubrication block in hole, while in bearing body
Surface forms one layer of solid lubricant film, and self-lubricating can be achieved, and greasy property is good, and coefficient of friction is small；Meanwhile, bearing body is using more
Layer composite construction, with good anti-wear performance, high mechanical strength, bearing capacity is strong, can avoid due to being lubricated between axle and bearing
It is not good to cause frictional heating operating temperature is risen problem, during shutdown, it can reduce and directly contact between friction pair metal, thus reduce
The resistance reset, under very high load, it may have good using effect.
Brief description of the drawings
Fig. 1 is the three-dimensional structure diagram of self-lubricating guide vanes of water turbine bearing；
Fig. 2 is the sectional structure chart of self-lubricating guide vanes of water turbine bearing.
Embodiment
Below by way of embodiment, the utility model will be further described.
Referring to figs. 1 to shown in Fig. 2, a kind of self-lubricating guide vanes of water turbine bearing includes bearing body, bearing body includes
Have metallic base layer 1, porous intermediate layer 2 and a solid lubricant layer 3, metallic base layer 1, porous intermediate layer 2 and solid lubricant layer 3 by
It is combined as a whole successively outside to inside；
The outer surface of metallic base layer 1 also incorporates coating for protection against corrosion 11；
Porous intermediate layer 2 is formed by sintered, spherical bronze powder；
The surface of solid lubricant layer 3 is provided with multiple equally distributed holes 31, hole 31 and is inlaid with solid stick 32,
And solid lubrication layer surface is provided with one layer of solid lubricant film 33, wherein hole 31 be arranged at solid lubrication layer surface through hole or
Blind hole, solid stick 32 is made of modified plastics, and solid lubricant film 32 is moistened by the solid for being coated on solid stick surface
Lubrication prescription is formed.
Referring to figs. 1 to shown in Fig. 2, by setting multiple equally distributed holes 31 on bearing body, and in hole 31
Middle inlaid solid lubrication block 32, while forming one layer of solid lubricant film 33 on the surface of bearing body 1, can be achieved self-lubricating, lubrication
Performance is good, and coefficient of friction is small；Meanwhile, bearing body 1 uses multi-layer compound structure, with good anti-wear performance, mechanical strength
Height, bearing capacity is strong, can avoid due to lubricated between axle and bearing it is not good cause frictional heating operating temperature is risen problem, shut down
When, it can reduce and directly contact between friction pair metal, thus the resistance reset is reduced, under very high load, also have
There is good using effect.
An embodiment of the present utility model is above are only, but design concept of the present utility model is not limited to
This, all changes for carrying out unsubstantiality to the utility model using this design all should belong to infringement the utility model protection domain
Behavior.
