Brief introduction to the problem of gear tooth surface hardness

　　Nowadays, our daily life is more and more inseparable from electronic mechanical products. We know that the composition of electronic mechanical products is very complicated. There are many parts in them. Among them, a very common and important part is gears. .I believe everyone must have seen gears, but do you know that gears can be classified according to the hardness of noodles? Yes, the hardness of noodles is also different. Many people may not know this. Let us followGear manufacturersLet's take a look.

　　According to the hardness of the tooth surface, gears can be divided into two types: soft tooth surface and hard tooth surface.Gears with soft tooth surfaces have low load-bearing capacity, but they are easier to manufacture and have good running-in performance. They are mostly used in general machinery with no strict restrictions on transmission size and weight and small-volume production.

　　Among the matched gears, the small wheel bears a heavier burden. Therefore, in order to make the working life of the large and small gears roughly equal, the hardness of the tooth surface of the small wheel is generally higher than that of the large wheel.Hardened gears have a high load-bearing capacity. After the gears are cut, they are quenched, surface quenched or carburized and quenched to increase the hardness.

　　But in the heat treatment, the gear will inevitably be deformed, so after the heat treatment, grinding, grinding or fine cutting must be carried out to improve the accuracy of the gear due to the error caused by the deformation.

　　Through the above description, I think you should also have your own understanding and understanding of the hardness of the gear tooth surface. I hope you can pay more attention to gear knowledge when you have time, and you can also pay more attention to our website, our company ProfessionallyGear processingAnd production, I believe we can still provide you with pertinent suggestions in this regard.
