How to select the speed reducer

Everyone according to the size of the gear reducer gear surface hardness, the gear reducer into hard tooth face reducer and soft tooth surface reducer, on the appearance design, structure is basically no difference, the key in the gear, vortex rod calcination raw materials has a certain difference, lead to two kinds of commodity load, service life and application category. Generally speaking, the gear of high power gear reducer is made of raw materials with high hardness, such as 45 steel, the selection of nitriding heat treatment process to make the hardness above 350 HBS, the gear reducer above this hardness is called hard tooth face gear reducer.The hard tooth gear reducer is not only the high hardness of the gear, but also the hardness of the output shaft and input shaft is much higher than the general gear reducer. Due to the large output power, the raw material of the shell is also made of pig iron calcination, which can very well adapt to the vibration and impact force caused by high load. Service life is longer, suitable for high-load equipment applications. Due to the improvement of raw materials and industrial production, the price of the hard tooth surface reducer is relatively higher. Soft tooth surface product series is the general, gear has not experienced hardness production processing or precision did not achieve the hard tooth surface provisions of the commodity.The main use of soft tooth surface reducer is very common, a variety of automatic packaging machine, conveyor and other small output power equipment application is very common. Its processing technology is simple, the relatively cheap price is also in line with the customer regulations, is the current market application of more commodities. In the purchase of gear reducer, the first to know their selected goods can meet the requirements, such as soft tooth surface reducer can not have to consume money to buy hard tooth surface reducer, its role is all the same, only a high power high load application, the general transmission system soft tooth surface goods is enough to solve.
