Briefly describe the difference between planetary reducer and gear reducer

Planetary reducer and gear reducer are two kinds of common reduction equipment. They have different structures, technical parameters, transmission efficiency, reduction range and application scenarios; The planetary reducer has small structure, small well meeting interval, high accuracy, long service life and large rated output torque; However, the price is a little bit expensive. Generally, the planetary reducer is used when high torque is required in limited space, that is, small size and large torque. Its reliability and service life are better than those of spur gear reducer.

The spur gear reducer is used for applications with low current consumption, low noise, high efficiency and low cost; The planetary reducer has small volume, large output torque and high transmission efficiency. It can be used in cutting machine, pipe bender, bucket wheel, cement production line, grease processing, fertilizer, power station, cement, glass and other industries.

1、 Structure comparison

The main transmission structure of the planetary reducer is composed of planetary gear, sun gear, inner ring, transmission shaft, box, motor and output shaft, which can realize the separate functions of power classification and multi tooth meshing. It has high stiffness, high accuracy (one level is within 1 point), and high transmission efficiency (short level is 97% - 98%), which is incomparable to ordinary gear reducers.

The main transmission structure of gear reducer is composed of box, gear, shaft, bearing, bearing cover, etc. The three-stage gear reducer is composed of multiple sets of gears; Features of planetary reducer: light weight, small size, large transmission ratio range, high efficiency, smooth operation, low noise, strong adaptability, high transmission accuracy, wide deceleration range, precision reducer, with a reduction ratio of 0.1 to 0.5 rpm.

2、 Features of gear reducer

1. The gear is made of high-strength low-carbon alloy steel, carburized and quenched, and the tooth surface hardness reaches HRC58-62. The gear is made of CNC polishing process, with high precision and good contact.

2. High transmission rate: single level is more than 96.5%, second level is more than 93%, and third level is more than 90%.

3. Stable operation and low noise.

4. Small size, light weight, long service life and strong bearing capacity.
