When bearing which must change new defects

When bearing. What defects must change new bearing is mass production of mechanical parts) and is very strict with industrial or manufacturing precision made in technology made by the high degree of specialization, sometimes circumstances when bearing severe fever in the operation. And then we should be a new clothes or cleaning oil change). In this case just bearing rapidly warming) is a serious fever). How do we go to understand its causes, what the causes of the grease is added too much? Or operation of the object and the bearing friction heat and cause a fever? Today engineers and everyone using critical to identify the reason. When bearing. What defects must change new, 1) Indentation. When hard into the raceway often pressure in the bearing running will be out of the pit. Not only that, but also too much noise or sound of pits and produces vibration and bearing severe fever. （ 2) Figure broken bearing. Sometimes engineer to draw the drawings didn't keep, broke the possibility of drawing is uncertain. If the size of the shaft is too big or inappropriate produces burst damage and bearing inner and outer ring and thrust bearing moving coil being broken. （ 3) Maintains a fracture. Cage is also one of them, cage and bearing a part of the roll body, so is basically in material and manufacturing ( www。 szjishen。 com） The problem. When installation wounded cage sometimes cause too early fracture. （ 4) Rolling body fracture. Bearing roll shape of an object and the damage in the running race will produce shock ear noise model, and is mostly belongs to the material or improper heat treatment. （ 5) Current corrosion. If when welding current pass bearing fever produced sparks makes raceway small burns. So you must see to it that when welding welding 'ground' as close to the welding points do not allow the welding current through bearings. The above information is 'when bearing.
