Briefly describe the difference between a planetary reducer and a gear reducer

Planetary reducers and gear reducers are two common types of reduction equipment.They have different structures, technical parameters, transmission efficiencies, lowering ranges and application schemes; planetary reducers have smaller structures, good meeting intervals, high precision, long service life and rated rated output torque; however, the price is a bit expensive.Generally, planetary reducers are used when high torque is required in limited space (ie small size and high torque).Its reliability and service life is better than that of the Spur lowering gear.

The stimulator reducer is used for low current consumption, low noise, high efficiency and low cost applications; the planetary reducer has smaller volume, larger output torque and high transmission efficiency.It can be used in cutting machines, pipe bends, bucket wheels, cement production lines, oil processing, fertilizers, power stations, cement, glass and other industries.

1. Structural comparison

The main transmission structure of the planetary reducer is composed of planetary gears, sun gears, inner rings, gearbox shafts, boxes, motors and output shafts, which can realize the separate functions of power classification and multi-tooth entrainment.It has high rigidity, high precision (one level is within 1 minute), and high transmission efficiency (short level is 97%-98%), which is unparalleled for ordinary gear reducers.

The main transmission structure of the gear reducer is composed of boxes, gears, shafts, bearings, bearing covers, etc.A three-stage gear reducer consists 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, reduction ratio from 0.1 to 0.5 rpm.

function of the shifter 2,

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

2. High transmission rate: single stage over 96.5%, second stage over 93%, third stage over 90%.

3. Stable operation and low noise.

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

The above is 'What is the difference between a planetary reducer and a gear reducer?
