Reduce the FAG cylindrical roller bearing noise maintenance lubrication method is introduced

Removed in order to distinguish the FAG bearings can be able to use, check after the cylindrical roller bearing is washed clean. Check the raceway surface, rolling surface, cooperate with the state, adhere to the wear condition, the increase of the bearing clearance and has nothing to do with dimension precision landing damage, abnormal. Non separation small ball bearing, the extent of support to inner ring with one hand, rotate the outer ring can confirm fluently. Bearing maintenance: cylindrical roller bearing cleaning: removing bearing under repair, the appearance of the first recorded cylindrical roller bearing, confirm the residual stock of smooth agent, sampling inspection with the smooth agent, after washing the bearing. Common use gasoline, kerosene as a cleaning agent. Are FAG bearing industry, the use of that type of grease maximum bearing in high speed wire-rod mill, accounts for about 70% points with the amount of fat. Because that kind of grease used fiber soft, white light to filter of lithium do thickener, use of mineral oil for essential oil, very light is difficult to know the foot outside the low-grade cylindrical roller bearings reduce the requirement of vibration value. Another benefit is no bad good pumping, whether mechanical fatliquoring, is still the manual besmear butter, tough is concise. And, the lower the price of the grease, can greatly reduce the cost of the bearing. However, due to the use of the mineral oil, make the type of grease is rust and antirust function on the outside of some physical and chemical target to play close button. Such as bearing life can reach 200 hours, linear guide to common problems. Starting and running torque is - 20 ℃ test when there is no problem. The use of grease temperature is commonly - 20 ~ 120 ℃, when was above 150 ℃ high temperature use, will bring about the ultimate oil evaporation too fast, abort the phenomenon such as severe, greatly shorten the FAG bearing using life. At present, the use of increasingly fine fine bearing equipment, prompting FAG bearing grease used must have the following functions: ( 1) No and FAG bearing the same operation life, maintenance cycle, delay as far as possible to shorten downtime, Labour production rate. ( 2) Is a dn> under the high speed of 5 x 105 to guaranteeing the motor temperature rise is low, don't jilt oil, thus reducing power consumption, shield machine. ( 3) The scalar content restraint is inevitable under the standard, the most earth cutting equipment noise pollution to the situation. ( 4) Is doing on the premise of guaranteeing cryogenic engineering starting and running of the spiritual FAG bearing, SKF bearing common problems. Guaranteeing the output power is minimal. Tear open come down to the cleaning of cylindrical roller bearing, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if rotating the FAG bearings with dirt, can injure the rolling surface of the cylindrical roller bearing, should be pay attention to. In coarse clean oil, use brush clean up to smooth grease, adhesive, after clean, roughly into fine cleaning).
