The difference and application of planetary reducers between three-star and five-star wheels
Planetary gearboxes have numerous significant advantages. Firstly, it has extremely high transmission efficiency, which can minimize energy loss to the greatest extent possible. Secondly, it has outstanding load-bearing capacity and can handle larger loads, ensuring stable and reliable operation even under heavy load conditions. Furthermore, its high transmission accuracy ensures precise movement of the mechanical system, which is crucial for equipment that requires high precision. In addition, it also has the advantages of smooth operation and low noise, bringing a good working environment experience. Next, let's follow the manufacturer of planetary gearboxes to learn about the differences and applications of planetary gearboxes with three-star and five-star wheels.
1、 Samsung planetary gearbox
Structural features:
A three-star planetary gearbox typically consists of a sun gear, three planetary gears, and an internal gear ring.
The planetary gear rotates around the sun gear while meshing with the inner ring gear.
This structure allows the input shaft and output shaft to be on the same axis, with a high degree of coaxiality.
Working principle:
When the input shaft rotates, the sun gear drives the planetary gears to rotate.
The planetary gear revolves around the sun gear while rotating on its own.
Due to the meshing between the planetary gear and the inner ring gear, the output shaft produces a deceleration effect.
Advantages:
Compact structure, small volume, and light weight.
The transmission efficiency is high, generally reaching over 90%.
Strong load-bearing capacity, capable of withstanding large radial and axial loads.
High precision, smooth transmission, and low noise.
Application areas:
Samsung planetary gearboxes are widely used in various mechanical equipment, such as industrial robots, CNC machine tools, automated production lines, etc.
It is suitable for situations that require high precision, high reliability, and high transmission efficiency.
2、 Five star planetary gearbox
Structural features:
The structure of a five-star planetary gearbox is similar to that of a three-star planetary gearbox, but it has five planetary gears.
Five planetary gears are evenly distributed around the sun gear, increasing the load-bearing capacity and stability of the gearbox.
Working principle:
The working principle is the same as that of a three-star planetary gearbox. The input shaft drives the sun gear to rotate, and the planetary gear achieves deceleration through meshing with the internal gear ring while revolving and rotating.
