Nowadays, laser cutting machines have been widely used in various manufacturing and processing industries because of their fast cutting speed, high efficiency and good cutting effect. The main transmission components of laser cutting machine are rack and pinion and ball screw. That is to say, the transmission mode of laser cutting machine is generally driven by two transmission modes: rack and ball screw. Why are these two methods used? Are there any advantages to using these two types of laser cutting machines? What is the principle? Let's analyze the Leapion laser for everyone.

The first transmission mode of laser cutting machine: rack and pinion transmission

In the rack and pinion transmission mode, the rack is also divided into a straight rack and a helical rack, which are paired with a spur gear and a helical gear respectively; the tooth profile of the rack is a straight line instead of an involute (toothed) For the surface, it is a plane), which is equivalent to an infinite cylindrical gear with an index circle radius.

1. Working principle of rack drive:

Gears and racks are mechanical parts with teeth that can mesh with each other. Rack and pinion are divided into straight teeth and helical teeth. Rack and pinion are widely used in mechanical equipment to realize transfer motion, change the speed of motion, and change the direction of motion.

2. Advantages of racks:

1) The rack can be extended indefinitely, adapting to long-distance movement;

2) The load-bearing capacity of the rack is stronger than that of the ball screw, and it can work under high load and heavy load;

3) The rack and pinion are relatively easy to manufacture, and the installation is relatively simple.

The second transmission mode of laser cutting machine: ball screw transmission

 Ball screw drive is an ideal product to convert rotary motion into linear motion, or convert linear motion into rotary motion. The ball screw is composed of a screw, a nut and a ball, and its function is to convert rotary motion into linear motion.

1. The working principle of ball screw drive

The development of ball screw technology has changed the bearing from rolling action to sliding action. Because of its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments, as well as laser cutting machines.

2. Advantages of ball screw:

1) High transmission efficiency;

2) The transmission is sensitive and stable;

3) High positioning accuracy;

4) Good accuracy retention;

5) High transmission rigidity;

6) Good synchronization performance.

 

It can be seen that whether it is rack drive or ball screw drive, the two common transmission methods of laser cutting machines have their own advantages. The rack and pinion transmission can be faster and the transmission distance can be longer; the precision and repeatability of the ball screw is slightly better, but the speed is slow and the length is limited.
