INA thrust tapered roller bearing in the process of using noise related problems to solve

Grease lubricated bearing limit speed than oil lubricated bearing limit rotational speed is low, the thrust tapered roller bearing oil way to have influence on the limiting speed can be achieved. Must pay attention to, the grease lubricated bearing, its limit rotational speed is generally only the INA bearing with a repeated cycle of high quality oil system of the limit speed of 80%, but the oil mist lubrication system, its limit rotational speed is generally higher than the same basic lubrication system 50%. 1, scars and its control method of rolling bearing rolling appearance if there is crack, indentation, or rust, like rivet rivet will attack the periodic 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 control method are: no percussion import bearings, INA bearing and shaft assembly after a load bearing seat when avoid bearing oblique; Inventory to avoid thrust tapered roller bearing corrosion and transport to avoid impact vibration; Using high viscosity of smooth and fat. 2, dust ring rolling bearing with dust and other foreign body and its restraint, will attack the periodic vibration and so-called dust noise, the vibration and noise of intrusive, and with or without. Dust acoustic control measures are: to improve the bearing cleaning method, before the device will import bearings, shaft, 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, lubrication elements make up the noise and its countermeasures of lubricant aging scleroma, choose wrong, lack of lubricant or attack can incur import 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. Cage design and structure also affect the limit speed of the thrust tapered roller bearings, due to move the body and frame is sliding contact surfaces, the use of more expensive, design reasonable, with high quality and low friction material of the cage, not only can move by body, and help maintain lubricating film in sliding contact. But like punching cage cage, such as low price, usually can only keep moving body separation. As a result, they exist volatile accidents and harried sliding contact of the resulting in lower speed limit. Generally speaking, in high speed work situation appropriate chooses deep groove ball bearings, angular contact bearings, cylindrical roller bearing; In low speed working situation, can choose tapered roller bearings. Tapered roller bearing limit speed, generally about 65% of the deep groove ball bearings, cylindrical roller bearing, 70% of the 60% of the angular contact ball bearing. Thrust ball bearing limit rotational speed is low, can only be used for low speed occasion. For unified kind of bearing, the smaller the size, promised to speed the higher. When choosing INA bearings, should pay attention to make the actual speed is lower than the limit speed.
