Structure and Features of Right Angle Planetary Gearbox from Vicent's blog

1.What is a Right Angle Planetary Gearbox

A right angle planetary gearbox, also known as a bevel gearbox, is a gearbox that changes the direction of the rotating shaft by 90 degrees. It is a compact and efficient gear reducer that combines the advantages of right angle gearboxes and planetary gearbox mechanisms. Most right angle gearboxes operate at a 90 degree angle between the input and output. Depending on how the right angle gearbox or right angle planetary gearbox is constructed, shaft misalignment may occur. Right angle planetary gearboxes rely on the mechanism of planetary gearboxes. The basic structure of a planetary gearbox basically consists of a "sun gear" mounted in the center, an outer ring, planetary gears surrounding the sun gear, and a carrier.

2.Structure of a Right Angle Planetary Gearbox

It mainly consists of a sun gear, a ring gear, a planet carrier, and several planetary gears supported on the planet carrier. ‌This structure is a type of planetary gear system in which the sun gear, the ring gear, and the planet carrier have a common fixed axis. ‌The planetary gears are supported on the planetary gear shaft fixed to the planet carrier, and mesh with the sun gear and the ring gear at the same time. ‌This structure can achieve a variety of gear combinations, including low gear, medium gear, high gear (overdrive) and reverse gear, by adjusting the active and passive states of the sun gear, planetary carrier and ring gear. ‌When all moving parts are unconstrained, the transmission is in neutral state

3.Working principle of right-angle planetary gearbox

Mainly involves the combination of input shaft, output shaft and planetary gear. ‌The characteristic of this gearbox is that the input shaft and output shaft are arranged at right angles, and the planetary gears are connected through the inner ring gear and the outer ring gear. ‌When working, the input shaft provides power input through the motor or other power source to rotate the inner ring gear. ‌The inner ring gear drives the planetary gear, and the meshing between the planetary gear and the inner ring gear and the outer ring gear realizes power transmission and direction change, and finally outputs power through the output shaft. ‌This structure makes the right-angle planetary gearbox have a compact structural design, which can achieve efficient power transmission in a limited space, and has the characteristics of high transmission efficiency (generally more than 90%), strong load-bearing capacity, smooth operation, low noise, and long service life. ‌In addition, the reversing speed is fast and the precision is high, which is suitable for application environments with high steering precision requirements

4.Characteristics of right-angle planetary gearbox

1.Small size, light weight, and compact structure: Due to the design optimization of the planetary gearbox, its volume and weight are relatively small, while maintaining the compactness of the structure, which is suitable for application scenarios with limited space. ‌

2.Strong load-bearing capacity: The design of the planetary gearbox allows it to have a high load-bearing capacity, can withstand large forces and torques, and is suitable for applications requiring high loads. ‌

3.High drive efficiency: The symmetry and reasonable power distribution of the planetary gear system make the drive efficiency high, which can effectively convert power and reduce energy loss. ‌

4.Able to achieve complex movements: By properly selecting the type and distribution scheme of the planetary gearbox, it is possible to achieve synthetic and decomposed movements to meet various complex movement requirements. 

5.Good stability: The planetary gears use the same planetary wheels and center wheels for uniform distribution, which ensures the stability of the movement. At the same time, they have good impact resistance and vibration resistance, and work more reliably. ‌
