QY series reducer includes two series of hard tooth surface reducers for cranes, QYS type (three pivot type) and QYD type (base type). It has three types: three-stage, four-stage and three-four-stage combination. The QY reducer is welded with steel plates, the box is annealed to relieve pressure, the gears are made of high-quality low-carbon alloy steel, and the tooth surfaces are carburized and quenched. Grinding, consistent product quality and reliable performance. 1) High transport capacity. The gears are treated by carburizing, quenching and grinding,

which provides the condition for the generalization of low-speed cranes. According to the surface hardness of the gear reducer, we divide the gear reducer into hard tooth surface reducer and soft tooth surface reducer. There is almost no difference between the two in appearance and structure, mainly in the gear and worm. There are differences in the post-processing of the material forging machines, resulting in indifferent loads, life and application range of the two products. In general, the gears of high-power gear reducers are forged from high-hardness materials such as 45 steel. After the carburizing and quenching process, the hardness can reach 350 HBS or more, and the gear reducers that reach this hardness are called It is a hardened gear reducer. Hardened gear reducer not only has high hardness

single speed, but also the hardness of output shaft and input shaft is much higher than that of ordinary gear reducer. Due to its high power, the body material of its box is also made of cast iron, which can cope well with it. Shock and vibration forces at high loads. Longer life, suitable for high load instruments. Due to the strengthening of materials and industries, the price of hardened gear reducers is relatively higher. Soft tooth surface series products are ordinary products whose gears have not undergone hardness treatment or whose accuracy does not meet

the demands of the hard surfaces of the teeth. The soft tooth surface reducer has a very wide range of applications and is widely used in various packaging machines, conveyors and other low consumption equipment. Its simple process and relatively low price also satisfy the demands of customers and it is the most used product in the market. When buying a gear reducer, you must first understand whether the product you choose can meet the requirements. If your soft tooth surface reducer is capable, you don't need to waste money to buy a hard tooth surface reducer. Its functions are the same, it's just that when used under high power and high load, ordinary gear tooth soft surface products are sufficient.
