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.

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.
