The United States TIMKEN bearing clearance and import clearance lubrication routine inspection

The United States TIMKEN bearing clearance namely bearing in the bearing box mounted on shafts or not, will it a fixed housing, then the party has not been fixed do radial or axial movement of the mobile. According to the moving direction, can be divided into radial clearance and axial clearance. Clearance (in the operation of Called work clearance) For imported bearing fatigue life of rolling, the size of the temperature rise, noise, vibration and so on have an impact on performance. Measurement of bearing clearance, to obtain stable measured value, generally impose regulations on bearing load measurement. Therefore, the resulting measured values than real clearance ( Called the theory of clearance) Big, that is, to increase the measuring load produced by the elastic deformation. But in the United States TIMKEN bearing roller bearing, due to the elastic deformation is small, can be neglected. Before the installation of bearing internal clearance is generally expressed in the theory of clearance. Bearing lubrication is to use the rolling surface of relative movement between oil film will be separated from each other, not excessive wear and failure as a result of rough contacts. Users can attach great importance to the import bearing lubrication technology, can guarantee during the working life of the to, still can maintain the stable performance and rotation accuracy. Rotate the outer ring and flush the cage carefully, the rolling element and raceway border, the need to thoroughly clean the oil residue any part of it that was previously hidden. The United States TIMKEN bearing should be attached to rinse friendly dry cleaning, dry clean lined with neutral table support, or in the far infrared drying oven is slow. If the dry cleaning friendly dry or drying, the process should not take bearing ring, adhere to any frame or roller. Oil bearing in practice can be removed prior to the delivery test of oil seal, and immersed in acid free 3% kerosene or gasoline to clean. Should be required to check into lubricating oil and instant delivery, is dry or dry bearings. At this time no oil film, so as to protect the exterior surface of bearing, the inspectors do not allow direct contact with the skin of the process, the operator should wear clean gloves, hand painted with rust, but must be avoided in the hands of the rust inhibitor mixed the appearance of the United States TIMKEN bearings, or be the deviation of measurement results. Shall be immediately delivered or rust stock process, the entire inspection process should be completed, check the import bearings. Time is too long, lest cause corrosion. Pay attention to the pure gasoline use clean oil, also can cause corrosion. Bearing is dry, or dry, shall be in accordance with the provisions, check without the outer surface of the bearing oil film protection drip into the lubricating oil and instant delivery, at this point, the entire process of inspection, does not allow direct contact with human skin, the operator should wear clean gloves, hand painted with rust, but in the hands of mixed corrosion inhibitor of rolling bearing surface must be avoided, otherwise it will be the deviation of measurement results. The United States TIMKEN bearing inspection is immediately after the completion of delivery or rust counting process, seize the completion of the inspection process should be as far as possible don't last too long cause corrosion. Pay attention to the pure gasoline use clean oil, also can cause corrosion. Imported bearing lubrication grease lubrication and oil lubrication, grease lubrication facilities of the method is simple, the grease is not easy to leak, have certain waterproof, gas and other impurities into the bearing ability, therefore usually grease lubrication is widely used. Such as overloading, high speed, high temperature working condition of oil lubrication. Grease is composed of base oil, thickener and add agent. Base oil viscosity play an important role on the lubrication performance of the grease, the thickener composition on the performance of the fat, especially the temperature characteristic, water resistance, oil analysis, etc have important influence on, add agent is mainly used to enhance the resistance of gasification of the grease, rust, extreme pressure performance, etc.
