China wholesaler Diameter 20mm Metal Planetary Gearbox with Engine DC Motor gearbox for agricultural machinery

产品描述

We are a factory specialized in metal parts hardware & metal gearbox geared motor through powder metallurgy process .We services with ODM/OEM gearbox design and development , gearmotors manufacture.
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 .planetary gearboxes are especially efficient, they are suitable for continuous, intermittent and alternating operation as well as for clockwise and anticlockwise rotation. Their use results in an increased performance of the entire drive train since the choice of the right gearbox allows for a smaller motor and thereby increases the economic efficiency of the entire drive train.

Application: metal planetary gearboxes are designed for robustness to sustain intermittent or sudden load changes. Depending on the diameter size, these gearboxes can sustain an input speed of up to 20,000 min-1 or an output torque of up to 25 Nm when operating in intermittent cycles. Due to their low backlash characteristic and the resulting high accuracy, the metal planetary gearboxes are also ideally suited for precise positioning applications.

lanetary 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. 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.
7. Perfect precision: Most rotating angular stability improves the accuracy and reliability of the movement.
8. Lower noise level because there is more surface contact. Rolling is much softer and jumps are virtually nonexistent.
9. 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.
10. 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.
11. 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.
12. Maximum versatility: Its mechanism is contained in a cylindrical gearbox, which can be installed in almost any space.
