Chinese reducers are widely used in mining machinery, chemical industry, iron and steel metallurgy, light industry, environmental protection, papermaking, printing, lifting and transportation, food, and other industries.
Our miniature planetary gearboxes for concrete mixers include primary, secondary and tertiary, suitable for the required speed ratio ≤1500r/min, the working temperature is around -40~45℃, and the 2 wheels run alternately.
The miniature planetary gearbox for the concrete mixer is divided into two-stage, and three-stage, suitable for the required speed ratio of 25-4000, and the speed ratio is larger when used in conjunction with the R and K series reducers.

Selection of right-angle planetary gearbox for rotation:
Use the ideal reduction ratio closely.
Reduction ratio = servo motor speed/reducer output shaft speed
Torque calculation: Torque calculation is very important for the life of the reducer; pay attention to whether the maximum torque value (TP) of acceleration exceeds the maximum load torque of the reducer.
The applicable power is usually the applicable power of the servo models on the market. The applicability of the reducer is very high, and the working coefficient can be kept above 1.2, but the choice can also be determined according to your own needs.
