Question:

There is a gear that knows its teeth number and its outer diameter and asks for its modulus

There is a gear that knows its teeth number and its outer diameter and asks for its modulus

Answer:

Also in millimeters.Bevel gear,A big endian modulus me, the average modulus modulus mm and Xiaoduan modulus of m1.For cutting tools,There are corresponding cutter modulus, Mo and so on.Standard modulus is widely used.In metric gear drive, worm drive, synchronous toothed belt drive and ratchet, gear coupling, spline and other parts,Standard modulus is one of the most basic parameters.
Modulus is one of the most basic parameters of modular gear teeth.The modulus is greater,The higher the gear, the thicker it is,If the number of teeth of the gear must be,The radial size of the wheel is also greater.Modulus standards are based on requirements such as design, manufacture and inspection.For gears with non straight teeth,The modulus of normal modulus Mn, the end modulus MS and the axial modulus MX difference,They are in their respective pitch (normal pitch, tooth distance and axial pitch ratio) and pi,
In millimeters.International regulation,The ratio of the definition of indexing circular tooth pitch on P and sent to digital pi,Expressed in m,The unit is mm,The m=p/ school.
Here you introduce the modulus and commonly used formula. What is called gear modulus?Refers to the ratio of modulus of ipsilateral tooth tooth profile between the adjacent two teeth from T and PI (M = t/),
