Principle of planetary gear box: The drive source (motor) starts the sun gear by direct connection, and the sun gear drives the planetary gears which are combined in the planetary gear carrier. The entire planetary gear system runs automatically along the outer gear ring, and the planetary carrier is connected to the output shaft to achieve acceleration. Higher reduction ratios are achieved by multiplying and accumulating multiple sets of stage gears and planetary gears.
