Rack drive is a very efficient transmission method, usually used in applications with large axial forces. Its advantage is that the drive unit can maintain the same rigidity throughout the stroke length; in addition, for applications with a stroke greater than 2 meters It also has a very good economy.
The rack drive is driven by the back and forth rotation of the gear on a fixed rack: in principle, the rack is divided into two forms. Straight rack and helical rack, the standard part is 1 meter, and the length can be customized The length is 3 meters, and multiple racks can be docked with unlimited length.
The rack can be milled or grinded according to customer requirements. The rack can be made of different materials and undergo different hardening treatments. According to different load-bearing conditions, customers can choose tooth surface material tempering, induction hardening, laser hardening and other processes.
