The planetary gear motor refers to the layout of the motor gears, because the gears of the planetary gear motor are three small gears that rotate around the large gear, so we call this gear planetary gear layout, so we call this planetary gear layout .
2. Explanation of planetary gear motor:
Working life: The accumulative working time of the reducer under rated load and rated input speed.
Rated torque: It is the torque for long-term operation that during motor working. When the output speed is 100 rpm, the life of the gear motor is a rated life time. When over loaded, the life of the gear motor will be reduced.
Noise: The unit is decibel dB(A). This value is actually the measured value when the input speed is 3000 rpm, without load, and the interval of the reducer is 1 meter.
Backlash: The input end is fixed, and the output end rotates clockwise and counterclockwise. When the output end bears plus or minus 2% of the rated torque, the output end of the planetary reducer will have a slight angular displacement. This angular displacement is the return clearance , Also known as "backlash." The unit is "minute", which is 1/60 of a degree.
Planetary geared motor model selection, key points and common problems of planetary geared motor
1. Gear ratio selection:
Planetary gear motor is also called planetary gear motor, planetary gear motor or gearbox. In the reducer family, planetary reducers are widely used in automobile transmission, smart home, communication equipment, robots, mechanical equipment, industrial automation and other transmissions due to their small size, high transmission efficiency, wide deceleration range, and high precision. In the system. The planetary gear motor has a wide range of deceleration. When selecting technical parameters, the reduction ratio must be calculated before choosing a gearbox with a reasonable reduction ratio.
2. Selection of specifications and models:
After meeting the above standards, choose the planetary gearbox with the smallest volume, and the smaller volume reducer has a lower cost. If the indoor space is insufficient, a gearbox can be used for parallel connection, or an angle reducer can be used, which can rotate the torque by 90 degrees.
3. Selection of accuracy (backlash)
