The rack can be classified according to tooth shape, gear shape, tooth line shape, manufacturing process and other methods.
1. Gears are divided into cylindrical gears, straight teeth and helical teeth according to their shape.
2. Gears are divided into spur gears, helical gears and herringbone gears according to the shape of the tooth line.
3. According to the process, it can be divided into quenching, tempering, grinding, gear milling and gear grinding, which can be blackened as required.
Accuracy modulus of rack
At present, the accuracy level refers to the German standard, and the accuracy level is 1-13. We generally use 6-stage rack in application. Modular standard rack specifications, of which grade 8 is soft gear and grade 9 is milling gear.
The material is C45 carbon steel, which is widely used in automatic robots, gantry machining centers, laser cutting machines, aluminum profiles, woodworking centers, the seventh axis of trusses and other fields. This rack generally requires high precision, accurate positioning and stable operation.
