According to the tooth surface hardness of gear reducers, they are divided into hard tooth reducers and soft tooth reducers. There is basically no difference between the two in terms of appearance design and structure. The key is that there are certain differences in the calcination raw materials of gears and turbine rods in later production, resulting in differences in the load, service life, and applicability of the two products.
The gears of high-power reducers are generally forged from high hardness raw materials such as 45 steel. After nitriding heat treatment, the hardness reaches over 350hbs. Gears with a hardness higher than this are called hard tooth surface gear reducers. The hard tooth surface gear reducer not only has high gear hardness, but also its output and input shafts have much higher hardness than ordinary gear reducers. Due to its high output power, the raw material of the shell is also forged with pig iron, which can adapt well to the vibration and impact forces caused by high loads. Longer service life, suitable for high load equipment applications. Due to improvements in raw materials and industrial production, the price of hard tooth surface reducers is relatively high.
The soft tooth surface product series is a universal product for gears that have not undergone hardness production processing or whose accuracy does not meet the requirements for hard tooth surfaces. The tooth surface of the reducer is soft and widely used. Widely used in various automatic packaging machines, conveyors and other equipment with low output power. Its processing technology is simple, relatively cheap, and the price also meets customer regulations.
It is a widely used commodity in the current market. When purchasing a Chuangli Precision Gear reducer, the first thing to know is whether the product you have chosen meets the requirements. For example, if a soft tooth reducer can be used, you don't need to spend money on a hard tooth reducer. Its function is the same. A universal soft tooth product for transmission systems is sufficient to solve this problem when used only under high power and high load conditions.
