The reducer is a dynamic conveying mechanism. By adopting a gear reducer, the motor can achieve the required number of decelerations and obtain a larger torque. At present, the application range of the reducer has been widely used in the movement of transmission force and mechanism. From the construction of transport ships, automobiles, locomotives, heavy machinery, processing machinery and automated production equipment used in the machinery industry to the daily life of ordinary household appliances, watches and automobiles, its traces can be seen in almost all types of mechanical transmission systems . Clock and so on. Its application work can see the application of the reducer from the angle of high-power transmission, small load to precise transmission, and in industrial applications, the reducer has the function of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.
Compared with other gear reducers, the planetary reducer has many advantages. The planetary reducer can split power when transmitting power, and its input shaft is coaxial, which means that the output shaft and input shaft are set on the same main shaft on-line. It has the following characteristics:
1) The planetary reducer runs smoothly and has strong shock and vibration resistance
The planetary reducer uses several planetary gears with the same structure, evenly distributed around the center wheel, so that the forces of the planetary gears and the rotating arm can be balanced with each other. The coaxial reducer also increases the number of teeth involved in the meshing, so Planetary gear transmission runs smoothly;
2) The transmission ratio is large, which can realize motion synthesis and decomposition
The planetary reduction gear structure requires only a few gears to obtain a large transmission ratio. For example, the transmission ratio of an industrial planetary reducer can reach several thousand, and the planetary gear reduction ratio can maintain a compact structure and a small mass while maintaining a large transmission ratio. , Small size and other advantages;
3) The planetary reducer is small in size, compact in structure and large in load capacity
The planetary gear reducer has a power split and a coaxial transmission of each center wheel and a reasonable application of internal gears, so it can be very compact. Several planetary gears are evenly distributed around the center wheel to share the load. Make each gear bear a small load, and allow these gears to adopt a smaller module. The coaxial reducer makes full use of the volume of the inner ring gear itself in structure, so it is beneficial to reduce the gears and make the planetary reducer Small size, compact structure, and large carrying capacity;
4) High transmission efficiency of planetary reducer
The transmission structure of the planetary reducer is symmetrical, with a plurality of evenly distributed planetary wheels, and the reaction forces acting on the center wheel and the swing arm bearing can balance each other, thereby helping to improve the transmission efficiency.
