How was a High-quality Planetary Gearbox Born?
① Raw Material Preparation
Procurement and pretreatment: Select high-quality metal raw materials, such as cast iron, alloy steel, stainless steel, etc. After strict quality inspection, surface impurities are removed, and the parts are preliminarily cut into a shape close to the blank according to the required shape and size.
② Forging/Casting
Forging forming: planetary carrier, sun gear, inner gear ring, etc., usually using forging technology. After heating the metal at high temperature, it is hammered or pressed to form the desired preliminary shape.
Casting molding: For some large or complex structural components, casting technology may be used.
③ Rough Machining
Turning, milling, and drilling: After completing the basic forming, the rough parts are rough machined using a CNC machine tool to remove most of the excess, forming the basic contours and structural features of various components of the gearbox, including inner and outer cylindrical surfaces, planes, keyways, threaded holes, etc.
④ First Heat Treatment
Normalization, annealing, or tempering: Based on the material properties and subsequent processing requirements of the parts, appropriate heat treatment processes are carried out on the rough machined parts to improve the internal structure of the metal, adjust hardness and toughness, and facilitate subsequent mechanical processing.
⑤ Precision Processing
Grinding, honing, and gear hobbing: precision machining of heat-treated parts to ensure that the tooth shape, accuracy, and surface roughness of the gears meet the design requirements. The gear processing of planetary gears usually includes hobbing, shaving, or slotting, etc; The planetary carrier requires precision grinding and leveling treatment.
⑥ Second heat treatment
Carburization quenching, nitriding, or surface hardening treatment: For contact stress areas such as gears, surface strengthening treatment is carried out according to design requirements to improve wear resistance and hardness, and prevent early wear and fatigue failure caused by long-term operation.
⑦ Secondary precision machining
Grinding, polishing, and ultra precision machining: further improve the accuracy and surface quality of gears and other key components, reduce micro wear and noise, and improve overall transmission efficiency and service life.
⑧ Inspection stage
Dimensional inspection, hardness testing, and non-destructive testing: Strictly control the quality of all finished parts, including dimensional accuracy, surface quality, hardness testing, as well as necessary non-destructive testing such as magnetic particle testing, ultrasonic testing, etc., to ensure that the parts are free of cracks, inclusions, and other defects.
⑨ Assembly stage
Cleaning, applying lubricating grease, and assembly: After cleaning the parts, apply special lubricating oil or grease in a suitable position, and then assemble them in an orderly manner according to the design drawings and technical requirements to ensure the correct meshing of the gear pair and the correct installation of bearings and seals.
⑩ Testing Phase
Empty load test run, load test, and performance test: The assembled planetary gearbox must undergo strict pre factory testing, including empty load operation inspection, noise test, vibration test, and performance test under load, to ensure that it meets the design requirements and can operate stably for a long time under the predetermined working conditions.

Applications
Planetary Gearboxes for Cranes
In Tower Cranes, planetary gearboxes are widely used due to their high load-bearing capacity, high efficiency, and compact structural design.
- Slewing Drive is installed on the top of the tower crane, connecting the tower body and boom. Its main function is to enable the boom to achieve 360 degree unrestricted rotation to meet operational requirements in different directions, ensuring smooth and precise adjustment of boom direction even under full load conditions.
- Winch Drive is mainly used to lift heavy objects or control the descent speed of steel wire ropes. The planetary gearbox can effectively increase the torque provided by the motor here and adjust the lifting speed by changing the transmission ratio of the gearbox.
- For some tower cranes with self moving functions, especially when changing positions within the construction site, Travel Drive will use a walking drive system. The planetary gearbox in the walking drive is responsible for converting the power of the motor into sufficient torque to drive the overall movement of the crane, ensuring that the crane remains stable and safe during movement.
Planetary Gearboxes for Ship Machinery
In ship machinery, planetary gearboxes are widely used in various applications due to their excellent performance, including high torque density, high transmission efficiency, impact load resistance, and compact structure.
- Slewing Drive is commonly used in ship machinery, such as servo systems, deck machinery (such as cranes, winches), and rotating turrets on ships. For example, the planetary gearbox in the servo system can achieve precise control of the ship's navigation direction.
- Winch Drive planetary gearboxes are also widely used in various types of winch drive systems on ships, including anchor chain winches, mooring cable winches, cargo lifting winches, etc. In the winch drive device, ensure that the cable can be safely and effectively retracted or heavy objects can be lifted under various load conditions.
In addition, planetary gearboxes may also be used for other ship mechanical applications, such as propeller pitch systems, hatch opening and closing devices, ship lifting platform drives, etc., all of which require high-precision motion control, large torque transmission, and high-performance transmission in limited space.
Planetary Gearboxes for Mining Equipment
In mining equipment, planetary gearboxes are widely used in various transmission systems due to their superior torque amplification, compact structure, and high efficiency, including track drive and wheel drive.
- Track Drive: In the mining industry, planetary gearboxes are used as the core transmission components for the walking mechanism of large tracked excavators, loaders, transport vehicles (such as mining dump trucks), and other equipment. In the track drive system, the planetary gearbox can convert the power generated by the engine or motor through multi-stage deceleration and torque increase into a powerful torque sufficient to drive heavy tracks, ensuring that the equipment has high traction and stable travel speed when driving on rough or soft ground.
- Wheel Drive: Wheeled mining equipment, such as large mining trucks, underground mining scrapers, and multifunctional service vehicles, also utilize planetary gearbox technology. Within the drive axles of these devices, planetary gearboxes play a crucial role, ensuring sufficient driving force and flexible handling performance in complex mining environments through optimized transmission ratio distribution and efficient torque conversion.

Planetary Gearboxes for New Energy Industry
Wind Turbine
- Yaw Drive: The planetary gearbox is used for the yaw system of wind turbines, helping the wind blades face the wind direction to maximize energy capture efficiency.
- Pitch Drive: Each wind turbine blade has an independent pitch drive device, which includes a planetary gearbox to adjust the angle of attack of the blades, in order to control the aerodynamic effects on the windward side of the blades under different wind speed conditions, thereby maintaining stable power generation and protecting the wind turbine from excessive wind speed damage.
Solar Tracking Systems:
In order to improve energy capture efficiency, tracking systems in solar photovoltaic power plants and photothermal power plants often adopt biaxial or multi axis tracking methods, allowing solar panels to rotate along the trajectory of the sun. In this system, the planetary gearbox is used as a driving unit to achieve precise tracking angle adjustment and reduce energy loss caused by changes in the incidence angle of the sun.
Planetary Gearboxes for Agricultural Machinery
Planetary gearboxes are widely used in agricultural machinery, especially in feed mixers. Their main function is to reduce the high-speed rotation of motors or other power sources to the low-speed, high torque state required for suitable mixing operations, to ensure uniform and efficient feed mixing. In addition, planetary gearboxes are used in Planers, Harvesters, Tractors, and Tillage Equipment to provide high torque output and meet the operational requirements of agricultural machinery in heavy or muddy environments. They can convert high-speed power sources into low-speed high torque, which is beneficial for driving heavy mechanical components. And its compact structure takes up little space, making it suitable for integration into limited space transmission systems.
Accurate transmission ratio control ensures on-demand movement of agricultural machinery execution components and improves operational quality.
