Gears play a greater role in the equipment in the form of transmission. Although the price of gears is low and the appearance of gears looks relatively small, I believe that everyone dare not ignore the role of gears.If there is no gear, the equipment cannot work; if the gear quality is good, the equipment will run more smoothly; if the gear quality is defective, it will cause malfunctions during the operation of the equipment.There are many opportunities for you to see or use gears in your life, but do you really understand the corresponding knowledge of gears? If not, then please learn about the cutting and types of gears.

　　1. In gear cutting, it is usually stipulated that when the center line of the tool moves away from the wheel center, x takes a positive value, which is called positive displacement; when the center line of the tool moves closer to the wheel center, x takes a negative value, which is called negative displacement.

　　2. When using the generative method to process gears, if the center line NN of the rack-shaped tool is tangent to the index circle of the gear blank and performs pure rolling, the processed gear is called a standard gear.

　　3. If the center line of the rack-shaped tool is not tangent to the index circle of the gear blank, but another index line parallel to the center line of the tool is tangent to the index circle of the gear blank and performs pure rolling. The gear is called a radially shifted gear.

　　4. When machining radially shifted gears, the distance that the center line of the rack-shaped tool moves relative to the index circle of the gear to be processed is called the displacement, expressed by xm, x is the displacement coefficient, and m is the modulus.

　　This article introduces you to some simple knowledge of gears. If you are interested, you can learn about it. Sharing knowledge is a thing that can make you happy.The importance of gears is self-evident, but how can we correctly play the value of gears? It is nothing more than learning the knowledge of gears and having a corresponding understanding of the principles of gear applications. Make good use of gears as a foundation; then, do the maintenance of gears and keep the gears lubricated, which is to extend the life of the gears.This article is introduced here, thank you for reading.
