In the transmission, gears are an essential and important component, among which planetary gears are widely used in AT and CVT transmissions. Even in Toyota's amazing hybrid system THS, the core power distribution is a single planetary gear mechanism.
1). The transmission ratio of the gears that mesh with each other is i = n master/n slave = Z slave/Z master.
2). The external gears rotate in opposite directions and the internal gears rotate in the same direction.
1). Structural features:
The single-row single-stage planetary gear mechanism consists of a sun gear, a planet carrier, a planet gear and a ring gear;
The three components of the sun gear, planet carrier and ring gear are coaxial;
The planetary gear mechanism has a compact structure and can bear a large load;
Planetary wheels have both revolution and rotation;
2). Speed change principle:
The single-row single-pole planetary gear mechanism must fix one of the three components of the sun gear, gear ring and planet carrier, or interconnect two components together so that the input and output can obtain a certain transmission ratio. By changing the motion state of each element, multiple transmission ratios can be obtained.

1). As long as the planet carrier is input, no matter which one is fixed, the input and output are driven in the same direction and with increasing speed.
2). As long as the planet carrier outputs, no matter which one is fixed, the input and output are driven in the same direction and with reduced speed.
3) .As long as the planet carrier is fixed, no matter which input, input and output are reverse transmission.
4). If any two of the three components of the sun gear, ring gear, and planet carrier are connected, the other one will not be connected and self-connected, and the planet row will become a rigid body with the same speed and torque input and output, and the transmission ratio is 1.
5). There is no braking component, there is input but no output, and the transmission ratio is zero.
