The use of correct selection of IKO rail bearing maintenance method

According to the area of use and conditions of use and environmental conditions choose size, precision, with suitable for railway is the prerequisite of bearing life and reliability of the bearing. Use parts: IKO bearing is suitable for predominantly radial load under the combination of radial and axial load, usually with two sets of bearing pair is used, should be mainly in car wheel hub, before and after active transmission parts, such as bevel gear, differential, reducer. Allows speed: under the correct installation, lubrication good environment, allowing for railway bearing limit speed of 0. 3 - 0. 5 times. Generally under normal circumstances, with 0. 2 times the limit speed for the most appropriate. Allows tilt Angle: taper roller bearings are generally not allowed to have tilted axis relative to the shell hole, if there are any tilt, no more than 2 'biggest. Allow temperature: under normal load, and lubricant has a high temperature resistant performance, and abundant lubrication conditions, general bearing in - are allowed 30℃- Work under the temperature 150 ℃. The choice of bearing grease lubrication improper in the cause of premature failure IKO bearing accounted for 36%. General grease can not meet the needs of all kinds of special bearing applications, only use one or all kinds of general purpose grease to meet all of the railway bearing applications, problems will be caused by far outweighs the benefits of unified brand. Bearing application condition is varied, the correct lubrication is grease and bearing application conditions. Bearing grease is to ensure smooth and safe operation of IKO bearings and have the basis of maximum reliability, even in the most extreme working conditions. Can prevent pollutants from entering the bearing grease, buffer impact load and corrosion resistance. In the actual application to choose the appropriate grease is bearing the basic conditions for maximum service life. Correct selection of lubricant standard includes bearing type and size, temperature, speed, load and the desired service life and supplemental lubrication cycle. Initial radial clearance of bearing in the process of into reduced gradually, and pushed into the amount of size decide to cooperate. Prior to installation, therefore, must first the initial measurement of bearing radial clearance. In the process of bearing push, continuously measure the radial clearance, until meet the requirements of radial clearance is reduce the amount and range of the ideal. 1, first put bearing in gasoline cleaning, wipe the residual sludge and dirt on the railway bearing, bearing all rusty wipe gently with the metallographic sandpaper polished, until no fingered rough feel. 2, use dry cloth after cleaning the IKO bearing wiped dry, soaked in the anti-rust oil again. In this process, will fully contact with the anti-rust oil bearing, don't stop rotating bearing, so that the rust-proof oil forming oil film covering on the surface of bearing, achieve the goal of rust. 3, the next with lithium base grease, butter, evenly coated on the surface of bearing, including inside and outside the circle, wheels, cage. And wipe while rotating bearing, makes the butter into the real bearing internal, sufficient lubrication effect. 4, the last procedure is packaging. In order to save costs, we 'waste', scrapping of cement bags in the warehouse, the packing bag of cut into appropriate size, bearing a good tight, package, label after good bearing specifications back on the store shelves. 5, the use of thermal monitoring IKO bearing operating temperature at any time. If the railway bearing more than 125 ℃ temperature for a long time even move to reduce the bearing life.
