Gearbox is an important mechanical device. If you have any knowledge of industrial machinery, then you must have heard of this term. It plays a crucial role as a transmission device in many industrial applications.
But for non-professionals, understanding the working principle and structure of a gearbox can be quite challenging. In this article, we will explain the basic working principles and structure of a gearbox to help those who want to delve deeper into understanding gearboxes.
1.1 Working Method of Rolling Earth
The reducer is a device that drives an output shaft with a high-speed input. It is usually designed as a large gear in a geometric shape, with the number of teeth equal to the input gear. The motion of the gears can be simply described as a "rolling earth" working method, where the rotation of the input shaft gear causes the output shaft gear to rotate.
1.2 Working Method of Helical Gears
Helical gears are a type of rotating mechanical gear that you may have seen. Helical gears have an inclination and can mesh with the input shaft gear and output shaft gear. When the speed of the helical gear is higher than the input shaft gear, it will rotate the output shaft gear in the opposite direction. This working method allows the reducer to provide higher output torque in a small size, making it more effective in many applications.
1.3 Working Method of Planetary Gears
Planetary gears are considered the most commonly used gearbox mechanism. It consists of a circular gear (sun gear) and several gears (planet gears) rotating around it. The planet gears also have a rotating shaft that can rotate around the sun gear. The sun gear can rotate at a certain speed, and the planet gears synchronized with the sun gear will rotate at a slower speed.
The working principle of the gearbox is to convert high-speed input into low-speed and high-torque output. Different types of gearboxes can provide different speed and torque outputs. Next, we will provide a detailed introduction to the structure of the gearbox.
