What are the standard modulus of helical gears in mechanical design?
The selection of gear modulus should be based on the calculation of load conditions, taking full account of the factors such as the bending strength of the tooth root, the contact strength of the tooth surface, the material and the heat treatment conditions
Select the gear modulus, calculated according to the load condition, considering the tooth root bending strength, contact strength of tooth surface, material, heat treatment of a series of factors such as comprehensive selection, here, can not be a simple answer to how to choose, it is a science. You need professional study and experience to do well.
According to GB/T 1357, the modulus of an involute cylindrical gear does not specify the modulus series for the helical gear alone, and the normal modulus of the helical gear is calculated according to the modulus of the spur gear.Modulus series:0.1, 0.12, 0.15, 0.2, 0.25, 0.3, 0.4, 0.5, 0.6,, 0.81, 1.25, 1.52, 2.5345681012, 1620253240
