Application of Gear and Rack in Laser Mental Cutting Machine

Application of Gear and Rack in Laser Mental Cutting Machine

 

Gears are wheel-shaped mechanical parts that rely on the meshing of teeth to transmit torque. The gear can realize the functions of changing the rotation speed and torque, changing the movement direction and changing the movement form through transmission with other toothed mechanical parts (such as another gear, rack, worm). Due to the advantages of high transmission efficiency, accurate transmission ratio, and large power range, the gear structure is widely used in industrial products. The gear teeth interlock with each other, and one gear will drive the other gear to rotate to transmit power. To separate the two gears, you can also use chains, crawlers, and leather belts to drive the gears on both sides to transmit power.

1. The tooth profile of the rack is a straight line instead of an involute, which is equivalent to a cylindrical gear with an infinite radius. Racks can be divided into straight racks and helical racks, which are paired with straight and spur gears, respectively.

2. In the application of laser mental cutting machine, the rack and the cylindrical gear are usually used for the servo motor to transmit power, so that the laser cutting head can move in the X, Y, and Z directions to achieve the purpose of cutting various shapes of workpieces.

3. The helical racks and gears have better meshing degree, smooth transmission and low noise; the high degree of coincidence reduces the load of each pair of gears and improves the load-bearing capacity of the gears, so it is widely used in the manufacture of laser mental cutting machines .
