Description
Technical field
The utility model relates to the lubricating and cooling in mechanical lubrication cooling field, particularly a kind of rolling mill bearing.
Background technology
Lubricating oil or lubricating grease are generally all adopted in the lubricated cooling of bearing at present, generally all adopt lubricating oil on high temperature, the more steel rolling equipment of dust, and with the circulating lubricating device bearing are lubricated.Shown in Figure 1 is a kind of sendzimir mill back lining bearing lubricating and cooling that is used for---fog lubrication cooling device I; the draught pressure that the working roll of sendzimir mill produces; by a series of bigger backing rolls; by back lining bearing power is sent on the frame at last; therefore back lining bearing lubricated and cool off extremely important, adopt usually oil do medium with reduce between bearing friction, protection bearing surface, help heat radiation and remove exotic.This device mainly is by lubricating oil container 11, oil fog generator 12 is formed, compressed air is through moisture separator 13, pressure-reducing valve 14 and air heater 15 enter oil fog generator 12, in oil fog generator, according to the Venturi tube principle, utilizing high-voltage high-speed air stream to form negative pressure sucks the lubricating oil in the lubricating oil container 11 in the oil fog generator 12, utilize the aperture atomizing, formation contains the mist of oil of a large amount of air, send in the back lining bearing 20 of milling train, to bearing lubrication, cooling, and utilize the normal pressure of mist of oil in the sealing bearing to remove exotic and prevent that exotic from entering.On the output pipe of pressure-reducing valve 14, be connected to pressure sensor 16 and be used to detect gas pressure, and feed back to pressure-reducing valve 14 and enter air pressure in the oil fog generator 12 with control; On the output pipe of air heater 15, be provided with thermo detector 17, according to measured temperature FEEDBACK CONTROL air heater 15, with the temperature that guarantees to enter the air in the oil fog generator; On the output pipe of lubricating oil container 11, be provided with oil heater 18 and thermo detector 19, be used to control the temperature of lubricating cooling oil.
Shown in Figure 2 is the structure chart of the technological lubrication device II of sendzimir mill, technological lubrication adopts ROLLING OIL or emulsion to make lubricant medium usually, be used for reducing rolling deformation district contact surface coefficient of friction, reduce roll wear, cooling and flushing dirt, because the price of oil is expensive, attaching oil also cumbersome by the removing surface of rolling sheets, the general emulsion that adopts is made lubricant medium more, and the cooling effect of emulsion is better than lubricating oil.Therefore, the technology rolling lubrication is to be finished by independent lubricating and cooling.Technology rolling lubrication cooling device II mainly is made up of magnetic filter 21, dirty emulsion container 22, fine filter 23, emulsion container 24, cooler 25, emulsion gatherer 26, nozzle 27, soiling solution pump 28 and coolant pump 29.Wherein, the emulsion that the cooling of technology rolling lubrication is used, collect by emulsion feeder 26, filter through magnetic filter 21, enter dirty emulsion container 22 storages after removing the iron content in the emulsion, the emulsion that startup soiling solution pump 28 send the fine filter essence to filter into cleaning dirty emulsion is stored in the emulsion container 24, the emulsion that is stored in the emulsion container 24 is pressurizeed after cooler 25 coolings by coolant pump 29, spray to sheet material and the roll that is rolled by nozzle 30, rolled plate and roll are lubricated, cool off.
Existing above-mentioned cooling device in use because technology does not pass a test, does not have to solve well the sealing problem of back lining bearing.Cause the bearing lubrication dielectric leakage and mix, not only caused huge waste, and make the effect of rolling mill compound reduce, lost efficacy even with the technology rolling mill compound.If rolling mill compound is blended in the back lining bearing, go also can reduce the service life of bearing.The effect of milling train can not be fully played.
