INA high temperature bearing fault handling must pay attention to the problem

Bearing is an important part of a major industrial equipment. High temperature bearing problems may lead to costly downtime, equipment damage and failure. In addition, a large industrial INA bearings on behalf of a large amount of capital investment. In order to achieve high equipment performance and the lowest maintenance cost, reliable running, must follow the correct processing method. This includes the INA bearing storage, removal, cleaning, testing and installation. The service life of any bearing depends largely on the preventive maintenance and received it. This especially in industrial applications, often working conditions, heavy load, dust and pollution is a common size. Apply to all anti friction bearing design. INA bearings bearing store has a special anticorrosive coatings to choose from, but most of the high temperature bearing not corrosion resistant materials. In handling and storage of bearings, must be careful, to ensure that they will not rust or corrosion. Even if it is wet or unprotected left hand or a small amount of chemical gloves can lead to etch in a small area, it could cause bearing fatigue. New and restructuring the bearing has a protective coating to deliver goods, usually in a protective cover paper or other packaging, and in a carton or wooden cases. When received a new or changed INA bearings, not from the packaging, until ready to install in the application. ( 1) Scars of sound and its control method of rolling bearing rolling appearance if there is crack, indentation, or rust, will attack like rivet rivet cyclical vibration and noise, the cycle can be fixed but mostly, the corresponding relationship between rotating speed into the inevitable scars will continue in the channel, and scars on the ball, and the noise with the device and smooth and there is a premise of transformation. Device for this kind of noise restraint measures are: no knock bearing, high temperature bearing and shaft assembly after a load bearing seat when avoid INA bearings oblique; Inventory to avoid the bearing corrosion and transportation to avoid the impact of vibration; Using high viscosity of smooth and fat. ( 2) Dust acoustic rolling bearing with dust and other foreign body and its restraint, will attack the periodic vibration and so-called dust, the vibration and noise of intrusive, and with or without. Dust acoustic control measures are: to improve the high temperature bearing way to clean, before the device will be bearing, shaft and hole and matching parts all stern qing shen clean; Clear smooth agent inside the foreign body; To improve the bearing seal; Avoid using data not pure or foreign bodies are embedded plastic stick to. ( 3) Lubricating elements make up the noise and its countermeasures of lubricant selection error, lack of lubricant or aging scleroma, can cause high temperature bearing vibration and noise, and the noise is not necessarily the rules. About this situation, as long as chooses appropriate smooth agent, adjust its smooth dose, extends the using life of smooth agent and reasonable change cycle.
