Bipolar Planetary Gear

Bipolar planetary gears refer to a gear system that, in addition to being able to rotate around its own axis of rotation like a fixed axis gear, their axis of rotation also rotates with the planetary carrier around the axis of other gears.
The bipolar planetary gear mechanism is divided into single planetary row and double planetary row according to the number of sets of planetary gears installed on the planetary carrier.
Planetary gear transmission has been widely used in reducers, speed increasers and transmission devices in various mechanical transmission systems, especially in aircraft and vehicles (especially heavy-duty vehicles) because of its characteristics of "high load and large transmission ratio". vehicles) have been widely used.
