Planetary Gearsets & Gear Ratios

• The sun gear
• The planet gears and the planet gears’ carrier
• The ring gear

A planetary gearbox is a gearbox with the input shaft and output shaft aligned it offers high torque transmission with good stiffness and low noise , in a more compact foot print than other gearbox types . It can supply a lot of speed reduction and torque in a small package with the fixed axis .
A planetary gear set is made up of 3 types of gears , a sun gear , planet gears and a ring gear . The sun gear at high speed is located at the center of the gears , and transmits torque to the planet gears which are typically mounted on the moveable carrier .The planet gears around the central axis rotation ,mesh with the sun gear and an outer ring gear . As all the planet carriers turns , it delivers low-speed, high-torque output . And it used for Car , Electric Bicycle , Home Appliance , Precision electronic .

Planetary Gearbox advantages:

1. Provides high torque at slow speeds .
2. The shafts are made up of hardened and tempered alloy steel .
3. Sun gears ,planet gears and ring gears are made of powder metallurgy and sintering steel .
4. Low noise levels.
5. Good quality taper roller bearings for input and output shafts .
6. High efficiency .
7. Increased repeatability . Its  Its greater speed radial and axial load offers reliability and robustness, minimizing the misalignment of the gear. In addition, uniform transmission and low vibrations at different loads provide a perfect repeatability.
8. Perfect precision: Most rotating angular stability improves the accuracy and reliability of the movement.
9. Lower noise level because there is more surface contact. Rolling is much softer and jumps are virtually nonexistent.
10. Greater durability: Due to its torsional rigidity and better rolling. To improve this feature, your bearings help reduce the losses that would occur by rubbing the shaft on the box directly. Thus, greater efficiency of the gear and a much smoother operation is achieved.
11. Increased torque transmission: With more teeth in contact, the mechanism is able to transmit and withstand more torque. In addition, it does it in a more uniform manner.
12. Very good levels of efficiency: Planetary reducers offer greater efficiency and thanks to its design and internal layout losses are minimized during their work. In fact, today, this type of drive mechanisms are those that offer greater efficiency.
13. Maximum versatility: Its mechanism is contained in a cylindrical gearbox, which can be installed in almost any space.

PM process for custom metal planetary gearbox , geared motors .
The P/M process is an economical, environmentally clean, high production method for making parts exactly to or close to final dimensions.  With little or no machining operations required.
At present, parts with a complicated shape, tight-dimensional tolerances, controlled density and properties can be manufactured by powder metallurgy methods. A technological process of powder metallurgy ensures high flexibility in the selection of physiochemical properties and other requirements, including:

1. Production of structural parts with complex shapes .
2. Controlled porosity .
3. High mechanical strength and resistance to vibrations .
4. Controlled properties.
5. High mechanical strength and resistance to vibrations.
6. High manufacturing precision and good surface quality
7. Large number of production series .
8. Good tolerances .
