Basic Knowledge of Gear Reducer

The gear reducer is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other fields. The gear reducer should be used when: 1. High-speed shaft under 1500 rev / min 2. Gear peripheral speed is less than 20 m / sec 3. The working environment temperature is around -40-45 ℃. If less than 0 °C, before start the oil should be preheated to a temperature above 0 ℃ 4. The gear reducer can be used in both directions

RV Worm Gear Reducer

Machine Features 1. Gear is made of high-strength low-carbon alloy steel carburized. The surface hardness reaches HRC58-62 and the gears are processed by CNC grinding with high accuracy and good contact. 2. Transmission rate: single level is greater than 96.5%, two-stage is more than 93%, and three –level is more than 90%. 3. Smooth operation, low noise. 4. Small size, light weight, long life, and high load carrying capacity. 5. Easy to be overhauled, and easy to install

Power speed ratio torque reduction ratio: 25 ~ 4000r/min (RX, R, K series combination can achieve greater speed ratio) Output torque: 2600000Nm Motor power: 0.4-12934kW

Maintenance of gear reducer First, the reducer (such as helical gear reducer) uses 460 # load industrial gear oil, and working environment temperature is 0 to 40 ° C. Second, after the first 100 hours of use, you should wash inner cavity replaced with new gear oil after oil change once every 2,000 hours. Third, disassembly reducer should avoid hammering in order to avoid damage to the normal mechanical. Fourth, if shaft connected at oil leakage phenomenon, skeleton oil seal and seals should be replaced.

Features of four series of gear reducer 1. R, K, S, F four series gear reducers including worm gear reducer are designed and manufactured based on module combination system. They have lots of motor combinations, install forms and structure programs. They have fine drive score level which can meet different use conditions to achieve mechatronics. 2. The four series gear reducers use unit structure modular design principle which provide a significant reduction in the types and inventory parts. 3. The four series of gear reducers drive efficiency with low energy consumption and superior performance. 4. They have the high rigidity ribbed cast iron box. The gears are made of high quality alloy steel with hardened surface carburizing by precision machining grinding. They provide smooth transmission with low noise, high carrying capacity, low temperature rise, and long life. (formerly Zhujiang Reduction Machinery Factory), is the largest professional manufacturer of decelerators including gear reducers like worm speed reducer, bevel speed reducer and helical reducer etc. in South China.
