A planetary gear reducer is a reducer composed of one or more sets of planetary gears, sun gears, internal ring gears, etc. The small gear in the middle of the figure is the sun gear, and the multiple self rotating gears distributed in the inner ring gear and sun gear are the planetary gears.

Basic concepts and selection calculation of reducers
In plain language, a gearbox can be called a "speed reducer and power amplifier". Imagine the scenario of a car shifting gears and climbing hills. The working principle of a gearbox is similar, as it can cleverly convert the high-speed rotation of the motor into low-speed, high torque output. For example, a motor can rotate 1500 revolutions per minute, but after being "processed" by a reducer, the output end may only rotate 30 revolutions per minute. Don't underestimate this "slow and leisurely" output, but the force it generates is enough to lift hundreds of pounds of weight. Isn't it amazing!

Introduction to bearings for deceleration motors
What is a gearbox? Although it is low-key, it has long been integrated into daily life, from ships, cars, robots in transportation to common household appliances and clocks in daily life. As long as there is a need for deceleration, its presence is inevitable. To ensure the normal operation of the gearbox, it is necessary to talk about the parts responsible for supporting it

Humanoid robot - harmonic reducer
The reducer is an intermediate mechanism that connects the power source and the actuator, and has the function of matching speed and transmitting torque. In humanoid robots, reducers are one of the core precision components, mainly used to provide stable power support for joint movements, accounting for 30% of the value. The precision reducers used in robots mainly include harmonic reducers, planetary reducers, and RV reducers.
