Gearbox

The gearbox means that the machinery is consist of various gears in order to deliver the required power to rotate the axis.
It is divided by the reduction gearbox and high speed gearbox according to the type of transfer speed. And saying that If the speed of the driven shaft is lower than the drive shaft, it is reduction gear box. if higher , it is called high speed gearbox. Reduction gear box is mainly used for the purpose of obtaining high torque by slow down the rpm to the required rpm of the drive source(motor). High speed gearbox is used to for the purpose of obtaining a high speed rotation by increasing the limited rpm of the drive source (motor).
According to the type of gear (helical gear, bevel gear, planetary gear, worm gear, etc.), it is possible to produce in a variety of shape.

Advantages

Ensure Product Reliability
Based on the accumulated technology, implements optimized gear strength and shape Catia, Cad, Solid Edge, Kissoft, such as through a variety of design Tool. And established the most recent performance of the test equipment to ensure the reliability to meet customer needs
Product implementation for High Speed
By holding up-to-date precision machinery, produce high precision gear and have a high level of production and assembly techniques.so more than 5000RPM high speed gearbox production is possible.

Analysis
This analysis can optimize the design to meet
customer needs through the gear strength
calculations and optimum bearing selection.
