1.Definition knowing about helical planetary gearbox
The helical planetary gearbox is a precision mechanical transmission device that integrates theplanetary gear train structure and helical gear meshing technology. It takes the helical gear as the core meshing component, and through the cooperative operation of the sun gear, planetary gears, ring gear, and planetary carrier, it realizes the functions of speed reduction, torque amplification, and power transmission. Its gear teeth adopt a helical structure, which can achieve continuous and smooth meshing between gears.
2.Key components of right angle planetary gearbox
1.Helical sun gear:As the power input core of the gearbox, the helical sun gear is usually connected to the motor output shaft and is responsible for transmitting the rotational power of the motor to the planetary gears.
2.Helical planetary gears:The helical planetary gears are the core transmission components between the sun gear and the ring gear. Generally, 3-6 planetary gears are evenly distributed on the planetary carrier.
3.Helical ring gear:The helical ring gear is a fixed or rotating internal gear that meshes with the planetary gears.
4.Planetary carrier:The planetary carrier is the component that connects the planetary gears and the output shaft. It is responsible for integrating the rotational power of multiple planetary gears and transmitting it to the output shaft.
5.Precision bearings and sealing components:Precision bearings and sealing components are auxiliary components that ensure the stable operation of the gearbox, but they are crucial to the performance and service life of the gearbox.

High transmission efficiency means less energy loss. In fields such as new energy vehicles, industrial fans, and water pumps, the use of helical planetary gearboxes can effectively reduce energy consumption.
4.Adapt to the development needs of emerging industries:With the rapid development of emerging industries such as medical equipment, 3D printing, and intelligent logistics, the demand for high-performance, compact, and low-noise transmission components is increasing. The helical planetary gearbox, with its compact structure (small volume and light weight), low noise (≤60dB under rated load), and strong versatility, can adapt to the installation and use requirements of emerging industry equipment.
