Product Description

The PAB planetary gear transmission mechanism is mainly composed of planetary gears, planet carriers and sun gears. The planetary gear transmission structure is the gear transmission structure with the highest transmission efficiency. When the precision planetary reducer is working, the prime mover such as a servo motor usually drives the sun wheel to rotate, and the meshing of the sun wheel and the planet wheel drives the planet wheel to rotate; at the same time, because the other side of the planet wheel is connected to the annular inner wall of the reducer housing, The ring gear engages, and eventually the planet gear, driven by its rotation, will roll on the annular inner ring gear in the same direction as the sun gear, forming a "revolutionary" motion around the sun gear.

The planetary wheel drives the planet carrier to rotate through revolution, and the planet carrier is connected with the output shaft to drive the output shaft to output torque. Usually, each precision planetary reducer will have multiple planetary gears, which will be driven by the rotation of the input shaft and the sun gear and rotate around the sun gear at the same time to jointly output power and drive the load movement. There is a difference in the number of teeth between the sun gear and the ring gear, thereby achieving the purpose of deceleration.
