Common train rolling bearing fault, column to harvest quite abundant

In recent days, read about beginner column on the BBS of related understanding of railway bearing of learning situation, one of the questions is 'train rolling bearing common wrong with what? 'According to this problem, China bearing network realized on the basis of summary, train rolling bearing common problems, there are mainly six here are detailed solutions, hope to help column inspection. Train rolling bearing common trouble, column inspection harvest quite abundant: 1, to handle the rotating bearing inner lack of oil bearing, a small, average 'hua hua' sound is normal, this is a separate roller load area ( Above the shaft neck) , fall on to insist on beams, the sound of every week is sound and continuous differences. When bearing inner lack of oil, there will be a roller impact on beams and sense of the impact of the regular and big and loud sound 'man'. 2, roller and raceway stripping, card bearing inner and outer ring raceway surface or roller rolling surface once present stripping, card, due to injury and falling to the rolling surface of melted metal, bearing rolling not sensitive, and every turn to stripping, the wounds have card lag phenomenon, at the same time, there are gaps, the sense of 'empty' this kind of phenomenon of roller or raceway part stripping, card. 3, roller broken when roller broken, according to the broken and scattered will present different levels of rotating insensitivity, until it is difficult to rotate both messy random vibration sense or sound. Turn the bearing by hand, when turn do not turn a hair or basic fixed roller broken. 4, bearing internal corrosion or entities eyewinker when bearing internal corrosion or entity foreign body, turn the bearing by hand, will present different sound or card lag phenomenon. 5, bearing internal rolling skin turn the bearing by hand if they give the dry friction of 'rustling' sound, and slightly quivering think this kind of phenomenon for bearing inner and outer ring raceway surface or roller rolling surface of the rolling skin. 6, after the seal seat scratches to handle the rotation shaft bearings, if rotating bearing resistance and friction, scratch journal after seal seat.
