Precision gears are toothed mechanical parts that can mesh with each other, and are widely used in mechanical transmission and the entire machinery.

The rack and pinion is quite stable in the process of transmission, so it is a relatively stable one among similar technologies, and it also has its own characteristics.

We mainly introduce the main features of various racks

Compared with the cylindrical gear reducer, the planetary gear reducer has many unique advantages. Its remarkable features are: it can divide power when transmitting power; at the same time, its input shaft and output shaft are coaxial, that is, the output shaft and the input shaft are set on the same main axis.

Today, I mainly introduce the common problems of gear reducers. In the future, you can refer to these problems for targeted repairs.

In addition to being able to rotate around their own axis of rotation like fixed-axis gears, their axis of rotation also rotates with the planet carrier around the axes of other gears. The rotation around its own axis is called "rotation", and the rotation around other gear axes is called "revolution", just like the planets in the solar system, so it is called planetary gear.

Speaking of the ball spline, many people know its working principle, that is, using the balls in the outer cylinder of the spline shaft, in the precision ground rolling groove, to perform smooth rolling motorized torque transmission, and it has a high degree of sensitivity.

There are two types of spiral bevel gears. In the helical gear, there are spur gears and curved gears according to the direction of the tooth length of the gear teeth. Their division is mainly based on the intersection of the ruler-length outline and the truncated cone.
