Milling machine at most how many teeth can gear, ask God for help
Therefore, the main factors that limit the number of processed teeth, in addition to the factors of the gear itself, are also affected by the machine tool stroke, rigidity and other factors. In addition to the above factors, there are still some teeth can not be divided by simple indexing method. Equal number of teeth must be calculated by hanging wheel method or double indexing and approximate indexing method. But for a gear with a large number of prime teeth, not all teeth can be equally divided by the index head.
First of all, the vertical stroke of the machine table itself can reach the maximum distance between the worktable and the spindle, which limits the outer diameter of the gear. At the same time, the center height of the index head used also limits the turning radius of the gear blank. The center height of the commonly used indexing head is usually 100mm, 125mm, 160mm and so on. When necessary, iron can be added to increase the turning radius of gear blank.
For ordinary milling machines, the number of teeth that can be machined is affected by many factors. The relationship between the outer diameter of the spur gear and the number of teeth is the number of teeth = the outer diameter / modulus -2, which determines the number of teeth to be related to the external diameter and modulus.
