Description
Technical field
This utility model belongs to mechanical manufacturing field, more particularly to a kind of for the big profile shaft such as cane milling or mining machinery
The lubrication that holds and cooling system.
Background technology
Bearing is for supporting axial workpiece and making the relative mechanical organ for sliding of loading end catch cropping, also referred to as sliding bearing
（Sliding Bearing）, sliding bearing stable working, reliability, noiseless, the bearing worked under sliding friction.Axle is by axle
The part for holding supporting is referred to as axle journal, and the part being engaged with axle journal is referred to as bearing shell.Bearing shell under the conditions of hydrodynamic lubrication, slidingsurface
Separated by lubricating oil and directly contact does not occur, friction loss and surface abrasion can also be greatly reduced, oil film also has certain
Vibration absorption ability.But it is larger to start frictional resistance.It is as key foundation parts in lathe, motor, electromotor and internal combustion
Extensive application on machine, especially in the heavy mechanical equipments such as cane milling, rolling machinery and mining machinery, employing
Parts are than relatively large, so for large-scale bearing, the quality of its performance directly affects the speed of equipment, carries energy
Power, functional reliability and service life, such as, in cane milling work, squeeze produced by the axle journal of roller and the bearing shell friction of bearing
Heat, the cooling jacket in cartridge housing carries out water cooling to back of bearing so that bearing shell is maintained at normal temperature range,
Due to being limited by cartridge housing, the water cooling area of this bearing is less, when continuously work and daily squeezed quantity are improved squeezer, special
Be not run into quality of lubrication oil bad, not in time lubrication, journal wear cause the feelings such as loose contact or chilled(cooling) water supply (CWS) deficiency
Condition so that the bearing run under low-speed heave-load is particularly the top roller bearing of squeezer, usually because the heat that friction is produced increases severely, leads
Cause bearing temperature rising, generation overheating deforming, and then leak occur and cause cooling and lubrication interruption, or even axle journal occur to emit
Cigarette ftractures, and causes stopping production accident.For this purpose, usually occur adopting the emergency measure for directly drenching cooling water to bearing in production, both
Environment is degrading, the moisture of sugarcane juice and bagasse is increased again, be increased energy consumption, improve production cost.Therefore, someone invents
The patent of some bearing shell coolings, the such as cooling of a kind of bearing shell base of Suzhou City Wuzhong District Guo lane rising sun space woollen sweater processing space application
Structure（Application number： 201410795586.5）, including the cooling duct being arranged in bearing shell base；The cooling duct includes
First cooling duct, the second cooling duct and Switching-through channel；First cooling duct and the second cooling duct are logical by switching
Road is communicated；First cooling duct and the second cooling duct are in " work " font；The cooling duct inwall is provided with one layer of anti-corrosion
Erosion layer；Outlet and water inlet is further respectively had on the cooling duct；The material of the corrosion-resistant coating is zinc.The method can be with
Reasonable solve traditional not enough shortcoming for directly pouring pouring, but still there are problems that, one is that cooling duct is rare, per
The endotherm area of bar passage burden, cooling are not uniform enough, and the cooling structure fails to cool down in place all of for bearing shell position, causes
The temperature of bearing shell or too high, two is that cooling-water duct radiating effect is poor, it is impossible to reach actual cooling effect, cooling effectiveness
Difference, causes bearing shell chassis interior to be corroded, and affects the normal use of bearing shell base；Three be the lubrication of bearing shell not enough, affect bearing shell
The rising of temperature, therefore, the applicant has applied for a kind of sliding bearing lubricating structure in 2015.02.14（Application number：
201520107137.7）, disclosing bearing lubrication structure includes that oil pipe, bearing base and bearing shell, the bearing shell Matching installation exist
Bearing block upper recess face；The bearing shell is formed by the bending of copper base-steel bi-metal section bar so as to include brasses face and steel tiling,
The steel tiling is contacted with the circular groove face of steel body pedestal；The oil pipe is placed on bearing shell and between bearing base
In cavity, the bearing shell is provided with several oilholes through bearing shell tiling, and the oil pipe is corresponded with oilhole and connected and which
One end forms on the steel tiling and therewith weld layer, the oil pipe other end be arranged on the side end face of bearing base and with
Formation weld layer sliding bearing generally comprise bearing base and bearing shell, bearing shell is on bearing base.The method can
Solve the shortcoming of traditional lack of lubrication to a certain extent, but yet suffer from some problems, one is to lubricate not enough uniformly,
Some significant points lubrication is less than causing the abrasion of bearing shell still can not mitigate；Two is the heavy damage due to being installed using copper pipe
The structure of bearing shell so that the intensity of bearing shell is high；Three is that the installation of copper pipe and machining difficulty are big so that whole bearing shell system
Complex process, high cost is made, the technology of the lubrication and cooling system of large size bearing is therefore broken through, is a technology urgently to be resolved hurrily
A difficult problem.
