1. 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
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

2. 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.
www.gearspeedreducer.com (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.
