Deep Groove Ball Bearings Mannage the Electric Cars’ “LIFE”
Electric cars as a low-carbon environmental protection of a preferred means of transport, now almost has been known as the most commonly used means of transport. But in the course of the follow-up will encounter a variety of problems. Many times we will hear the electric car will be issued noise, often do not know where the noise came from. As the electric car motor noise are generally bearing the problem, of course, there will be other reasons.
Electric motor bearings, also known as motor bearings or motor bearings, is specifically used in electric motors or motors on a special bearing. The bearing used in the motor is a part of the support shaft, it can guide the rotation of the shaft, can also bear the shaft idle parts, is a special part of the application of electric vehicles.
Often in the electric car used in the most extensive bearing is 6200 2rs bearing, deep groove ball bearing structure is simple, compared with other types easy to achieve higher manufacturing accuracy, can be mass production, manufacturing costs are lower , The use of very common. Deep groove ball bearings for high speed or even high speed operation, durability is also very high, do not often go to maintenance. The bearing friction coefficient is small, the limit speed is high, the structure is simple, the manufacturing cost is low, and it is easy to achieve high manufacturing precision.
In the electric car are often used are deep groove ball bearings, its structure is relatively simple, mainly used to bear the radial load, when increased radial bearing clearance, when there will be a certain angular contact bearings The performance of the situation in the relatively high speed of love should not use reasoning ball bearings when. Compared with other deep groove ball bearings, it is more applicable to the electric car, its bearing friction coefficient is relatively small, the limit speed is very high. Impatience and does not bear heavy load is its shortcomings. In short, electric car bearings relative to it is the best choice.
