Many causes loss of INA bearings, all design and manufacturing process factors are associated with loss of bearings, bad judgment to analysis. But in normal circumstances, generally can be used from both factors and internal factors to consider and analyse.
Loss factors mainly refer to the use of installation and adjustment of the bearing, maintenance, maintenance, repairs and other compliance with technical requirements. Installation conditions is one of the leading factors in the use factor, INA bearing package is often caused by installing is not the right state of change between the various parts of the bearing, functioning and loss of bearing an abnormal state.
Depending on the bearing of the installation, use, maintenance, maintenance technical requirements, the load borne by the bearing in operation, speed, temperature, vibration, noise monitoring and checks and lubrication conditions, abnormal findings immediately find the cause to adjust, bring it back to normal. In addition, analysis of the grease quality and atmosphere surrounding media, testing is also important.
(1) determine the INA bearing "care and maintenance" cycle * regular servicing and maintenance by maintenance and periodic maintenance and maintenance is composed of two parts.
(2) in in accordance with INA bearing regularly maintenance cycle maintenance Shi, must to focusing on important operation project: oil of check and replaced, and transmission oil liquid of check and replaced, and transmission belt of check and adjustment, and air filter manager of clean and replaced, and fuel system of clean and replaced, and steering system of check, and brake system of check, and spark plug of check and replaced, and are Shi belt or chain of replaced, and injector of regularly cleaning and solar term door body of cleaning,.
(3) different types of the same manufacturer production INA bearings, the same maintenance cycle, maintenance projects almost the same, INA bearings for replacement of versatile running material, practice the same, so conducive to determine maintenance cycle and action items.
(4) production equipment was different in the past, modern INA bearing almost no grease filling her mouth the whole car, no grease filling and maintenance projects.
(5) INA bearings are maintenance-free, round of Project Springboard the operation only bearings axial clearance checks, without bearing lubrication and maintenance projects, if the number of wheel bearing clearance is too large, is going to be round the Project Springboard bearing Assembly replaced.
(6) master maintenance cycle and maintenance of various items, follow the station operating procedures project layout, reducing repetitive operation, under the premise of ensuring job security, in the shortest time and maintenance projects, complete maintenance of INA bearing operation.
To check INA bearings should be clean before bearing surface, and then carefully check the bearing oil seal and its surrounding parts, if you have shown symptoms of bad, be sure to replace the bad oil seals will result in damage to, prevent bearing cloud properly and cause downtime.
