Servo Planetary Gearbox

The gearbox reduces the reflected load inertia by the square of the gear ratio, so adding a gearbox can significantly improve the system's inertia ratio. In the field of gearboxes, planetary gearboxes are gearboxes designed to align the input and output shafts, and are used to transmit the maximum torque, the torque density, in the most compact form. In order to increase the torque, the planetary gears are mounted on a unit called a coupling, which is connected to the output shaft. The output speed is lower than the drive speed, so the output torque is higher. The more gears mesh with each other, the higher the torque will be.

Advantages

The advantages of the servo planetary gearbox are high power density and small torsion clearance. Its high efficiency makes this gearbox suitable for continuous operation and can achieve the effect of minimum power consumption. They can achieve the highest speed, acceleration and positioning accuracy. In addition, the planetary gearbox has higher repeatability. Its higher radial and axial load speeds can provide perfect repeatability with uniform transmission under different loads and low vibration.


What is a Gearbox?

A gearbox is a mechanical device that can increase or decrease torque by reducing or increasing speed. It consists of two or more gears, one of which is driven by the motor unit. The output speed of the gearbox is inversely proportional to the gear ratio. The most common application of the gearbox is in automotive engineering, as a transmission device, used between the output shaft of the engine and the final drive, in order to transmit the required torque and power to the wheels of the vehicle.
 
The gearbox consists of gear sets, and the types of gears include spur gears, helical gears, bevel gears, worm gears and planetary gears. The gear set is based on the type of gearbox used in the operation. They are arranged in a special way to provide the required speed, such as a five-speed gearbox with reverse gear and an automatic transmission movement.
 
Inside the gearbox, the transmission mechanism is a physical process. The power transmission system provides controlled application of power. In general, the term "five-speed gearbox" refers only to gearboxes that use gears and gear trains, which provide speed and torque conversion from a rotating power source to a single or multiple devices.


Applications of Gearbox

In industry, the most common use of gearboxes is in automotive engineering. The transmission adapts the output of the internal combustion engine to the drive wheels. The engine needs to run at a relatively high speed as designed, which is not suitable for starting, stopping and slower running. At the same time, the transmission reduces the higher engine speed to a lower wheel speed, thereby increasing the torque throughout the process.
 
Such a transmission system is widely used because of its applicability. The transmission system is also used on other mechanisms, such as bicycles, stationary machines, and can handle the operation of motor force and strength at different speeds and torques. In addition to these uses, metalworking, plastic and rubber machinery also require the use of gearboxes in order to fully control the strength of the output motor.
 
For plastic injection machines, the gearbox is used to help mix the resin and the master batch filled into the hopper, so that they are well mixed together in the form of fluid for further injection into the mold. In addition to this use, there are many other cases of applications.


Automation

After introducing the gearbox, let us now enter the subject of the application. Many precision planetary gearbox models reduce the reflected load inertia while increasing the torque output of the servo system to achieve a higher response. Such a mechanism is helpful. They can provide high rigidity, high efficiency and very quiet operation for a variety of automated manufacturing processes in the industrial sector. With the help of the servo feature, all movements are activated in a smooth manner, thereby ensuring better movements and performance.
