Comparative analysis of planetary reducer and gear reducer

Planetary reducer and gear reducer are two kinds of common speed reduction equipment, the structure of planetary reducer and gear reducer are different, technical parameters are different, transmission efficiency, speed reduction range, application scenarios are also different.

The following are the characteristics of the two types of reducers. Structure comparison.

The main transmission structure of planetary reducer consists of planetary wheel, sun wheel, inner gear ring, transmission shaft, box, motor, output shaft assembly, planetary reducer can realize the effect of power shunt, multi-tooth meshing alone. Planetary reducer has high rigidity, high precision (single-stage can be achieved within 1 minute), high transmission efficiency (single-stage in 97%-98%), which is incomparable to ordinary gear reducer.

The main transmission structure of gear reducer is composed of box, gear, shaft, bearing and bearing cover, etc. The three-stage gear reducer is assembled and driven by multiple sets of gear sets.

Features.

Planetary reducer features: planetary gear reducer light weight, small size, large transmission ratio range, high efficiency, smooth operation, low noise adaptability, high transmission accuracy, wide range of deceleration, etc. Planetary reducer is a precision type reducer, the reduction ratio can be up to 0.1 rpm -0.5 rpm.

Gear reducer features.

1. Gears are made of high strength low carbon alloy steel by carburizing and quenching, the hardness of the tooth surface reaches HRC58-62, the gears are all made of CNC grinding technology, high precision, good contact.

2. High transmission rate: single-stage greater than 96.5%, double-stage greater than 93%, three-stage greater than 90%.

3. Smooth running and low noise.

4. Small volume, light weight, long service life and high bearing capacity.

Application path.

Gear reducer: applied in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceuticals and other fields.

Planetary reducer: applied in lifting and transportation, engineering machinery, metallurgy, mining, petrochemical industry, construction machinery, light industry and textile, instrumentation, automobile, ship, aerospace and other fields.
