Filling quantity of railway vehicles with the influence of rolling bearing

Filling quantity of railway vehicle in 2020 - the influence of rolling bearings 01 - 05 rolling bearing is an important part of a railway vehicle, for railway vehicle with rolling bearings, its friction coefficient is small, high speed, large carrying capacity and shorten the repair time, reduce the operation cost of railway wagon, easy to use, simple maintenance, and many other advantages, has been widely used in railway vehicle. Bearing maintenance as one of the important content of railway vehicle repair, mainly combined with simultaneous vehicle maintenance, the maintenance system and vehicle maintenance system of mutual constraint, mutual attachment, but relatively independent, relatively independent each other and influence each other. Rolling bearing maintenance after completion of assembly, in accordance with the provisions in the bearing inner note has a certain amount of grease. But, how much the amount of grease on the use of the bearing has a great influence. Grease is too little, in use is not easy to form the dynamic pressure bearing oil film, is easy to cause hot shaft due to short of oil. Too much grease, bearing in use is not easy to send out rolling friction heat, prone to early use heat, if not handled in time, can cause a bad grease caused by hot shaft. , therefore, must use when filling in the bearing has measuring function of automatic filling machine, at the same time bearing oil before and after oil must adopt electronic scales weighing, to determine the actual bearing oil; Before filling machine and electronic scale used, must be the amount of oil filling machine to check and confirm the electronic scale with standard weight correction. （ Source: the resources of railway vehicle platform)
