The soft tooth surface reducer is developed on the basis of the medium hard tooth surface reducer for QJ series cranes. Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH The QY series reducer includes two series of hard-tooth surface reducers for cranes, QYS type (three fulcrum) 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 stress, the gears are made of high-quality low-carbon alloy steel, and the tooth surfaces are carburized and quenched. Grinding, stable product quality and reliable performance. 1) High carrying capacity. The gears are processed by carburizing, quenching and grinding, Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH and the bearing capacity is greatly improved compared with the soft tooth surface and medium hard tooth surface gear reducers of quenched and tempered hobbing. 2) Small size and light weight. Compared with the soft tooth surface and medium hard tooth surface reducer. The same bearing capacity reducer can reduce 2-4 equivalent frame sizes. 3) High efficiency, low noise and small vibration. The gear grinding process has improved the accuracy level, Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH and the gears have been trimmed. The comprehensive efficiency of each gear stage is 0.98, and the vibration and noise are significantly reduced. 4) Multi-stage is adopted to reduce the single-stage speed ratio. The center distance can be opened to reduce the height of the reducer to meet the requirements of various crane mechanisms; the maximum nominal transmission ratio of the reducer reaches 400, which meets the requirements of slow-speed cranes. Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH 5) The three-point reducer can be installed vertically, horizontally, or even deflected to a certain angle, which is convenient and flexible. 6) This series of reducers has a combination of three and four stages (ie, three-stage assembly type, four-stage transmission ratio), Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH which provides the premise for the generalization of slow-speed cranes. According to the hardness of the gear surface of the gear reducer, we divide the gear reducer into a hard tooth surface reducer and a soft tooth surface reducer. There is almost no difference between the two in terms of appearance and structure, mainly in the gear and worm. There are differences in the post-processing of the forging material machines, resulting in different loads, lifespans and application ranges of the two products. Generally speaking, the gears of high-power gear reducers are forged from materials with high hardness, such as 45 steel. After the carburizing and quenching process, the hardness can reach 350HBS 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 of Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH single gear, but also the hardness of output shaft and input shaft is much higher than that of ordinary gear reducer. Because of its high power, the material of its box body is also made of cast iron, which can cope well with it. Vibration and shock forces at high loads. Longer service 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 processing or whose precision does not meet Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH the requirements of hard tooth surfaces. The soft tooth surface reducer has a very wide range of applications, and is widely used in various packaging machines, conveyors and other low-power equipment. Its simple process and relatively low price also meet customer requirements, and it is the most used product on the market. When purchasing a gear reducer, you must first understand whether the product you choose can meet the requirements. If the soft tooth surface reducer is competent, there is no need to waste money to buy a hard tooth surface reducer. Its functions are the same, just a When used under high power and high load, ordinary transmission soft tooth surface products are sufficient. ZQ500-8.23-1 Reducer ZQ reducer is mainly used in lifting, mining, general chemical, textile, light industry and other industries, Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH the speed is not more than 10 meters per second. Application of ZQ reducer: ZQ reducer is mainly used in lifting, mining, general chemical industry, textile, light industry and other industries. The speed of the high-speed shaft is not more than 1500 rpm; 3. The reducer is used for forward and reverse operation; 4. The working environment temperature of the reducer is -40℃ to 40℃ 4. The reducer has nine transmission ratios and nine configuration types And three low-speed shaft end types; 5.

The ZQ reducer has two stages of transmission, and there are nine types of assembly. ) coupling (type F). ZQ reducer difference: ZQ type is an involute cylindrical gear reducer, ZQ (H) type is a cylindrical gear reducer, which is formed on the basis of the ZQ type involute cylindrical gear reducer series. Time has proved that compared with the involute gear of the same specification, the arc gear not only has a long service life, but also has a large capacity, high strength and less wear on the tooth surface. These two reducers are mainly used for hoisting machinery, and can also be used in general equipment such as mining machinery, chemical industry, and light industry. The adaptation conditions are: the speed of the high-speed shaft is not greater than 1500r min, and the working ambient temperature is -40 to 45 degrees. It is suitable for forward and reverse two-way operation. The ZQD cylindrical gear reducer is based on the ZQ reducer. It becomes a three-stage reducer, Gearbox QJ-L QJ-T QJR-D QJR QJRS-D QJRS QJS-D QJS ZD ZDH ZL ZLH ZQ ZQA ZQD ZS ZSH which expands the transmission ratio of the reducer. ZQD type reducer is to add a high-speed stage called three-stage transmission under the premise of not changing the position and installation size of the input and output shafts of the ZQ-type reducer as much as possible, and the added high-speed stage is at the top. ZQD1000 250 reducer large transmission ratio reducer ZQD type large transmission ratio cylindrical gear reducer has six specifications: ZQD350 100, ZQD400 100, ZQD650 150, ZQD850 250 and ZQD1000 250. Center distance The nominal center distance of the ZQD reducer is the sum of the center distances of the middle and low speed stages.
