INA turbocharged bearing troubleshooting methods

INA bearing failure is often the case in the process of operation, so you don't have a cow. Malfunctioned, judgment and processing is the key. 1. Bearing temperature is too high, when the agency is running to install turbo bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal, conversely indicates that bearing temperature is too high. INA high bearing temperature are: the cause of lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Inadequate clearance) ; Turbo bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc. 2. Bearing noise rolling bearing in the work to allow running noise slightly, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Cause noise of rolling bearings is more complex, one is the bearing inner and outer surface wear. As this kind of wear and tear, destroy the INA bearing and shell, turbo bearing and shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. After bearing wear loose, loose cage damaged, also can produce sound bearing damage. 1, coarse clean, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). If rotating the turbo bearing with dirt, can damage the bearing rolling surface, should be pay attention to. 2, fine fine cleaning, INA bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. Bearing inspection and judgment: in order to judge whether the bearing of the removed can use, check after wash bearing. Maintenance content including: monitoring operation status, supplement and replacement of lubricants, sealed, check regularly, it is to maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. As maintenance issues in the operation, has the sound, vibration, temperature, lubricant, separation of INA bearings and bearing, rolling body, the outer ring raceway surface can be respectively. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, turbocharged the increase of the bearing clearance and has nothing to do with size precision falling damage anomalies. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring.
