Industrial Robot Planetary Gear Epicyclic Gear Set CNC Machining
For Robot Machines
Planetary gears, also known as epicyclic gears, are commonly used
in industrial robots for various applications that require
compactness, high gear ratios, and torque transmission. Here's how
planetary gears are utilized in industrial robots:
Compact Design: Planetary gears are known for their compactness,
making them ideal for applications where space is limited. The gear
system consists of a central sun gear, surrounding planet gears,
and an outer ring gear. This arrangement allows for a significant
gear reduction within a small footprint.
High Gear Ratios: Planetary gears offer the ability to achieve high
gear ratios in a single stage. By varying the number of teeth on
the sun gear, planet gears, and ring gear, different gear ratios
can be obtained. This is advantageous in industrial robots where
high torque or low-speed output is required.
Torque Transmission: Planetary gears are capable of transmitting
high torque due to the multiple points of contact between the
planet gears and the sun and ring gears. This makes them suitable
for applications in industrial robots that require high force
output, such as lifting heavy payloads or performing tasks that
demand strong gripping capabilities.
Speed Control: Planetary gears can be used to control the speed of
rotational motion in industrial robots. By adjusting the input
speed to the sun gear or the output speed from the ring gear, the
rotational speed of the robot's actuators or mechanisms can be
precisely controlled.
Backlash Reduction: Planetary gears can help minimize backlash,
which is the play or clearance between the teeth of gears. The
multiple points of contact between the planet gears and the sun and
ring gears distribute the load and reduce backlash. This enhances
the accuracy and repeatability of robot movements, particularly in
tasks that require precise positioning or fine adjustments.
Load Distribution: The distribution of the load across multiple
planet gears in a planetary gear system helps to evenly distribute
and share the torque, resulting in reduced wear and improved
overall performance.
Versatility: Planetary gears offer versatility in industrial robots
due to their modular design and the ability to combine multiple
stages. By stacking multiple planetary gear sets together,
different gear ratios and torque outputs can be achieved, allowing
for a wide range of applications and performance requirements.
It's important to note that while planetary gears offer numerous
advantages, they also have some limitations, such as increased
complexity, higher manufacturing costs, and slightly lower
efficiency compared to other gear types. Therefore, the selection
of planetary gears in industrial robots depends on specific
application requirements, such as torque, speed, compactness, and
cost considerations.

Company Profile
Our company was formerly known as Changsha Double Star Gear
Industrial Co., Ltd, which was established in 1994. It is a
directly affiliated university-run enterprise founded by Central
South University Professor Zeng Tao, the leading expert on spiral
bevel gears in China. It was later renamed as Changsha Senjie Gear
Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production
R&D base specializing in professional design, reserch,
manufacture and sales of high-quality small module spiral bevel
gears and high reduction hypoid gears and cylindrical gears. In
2023, Hunan Dinghan New Material Technology Co., Ltd. was
established as a specialized international export business
department. CSG has strong scientific research and development
capabilities and is also equipped a full set of advanced equipment
including seven-axis five-linkage CNC spiral bevel gear grinding
machines and gear milling machines. By making the best use of the
scientific and technological achievements and equipment of the Gear
Research Institute of Central South University, machanical
