I have two small gears,One of them: tooth crown circle diameter 24, root circle diameter about 18 (error is not more than 0.2, too small, bad amount), tooth number 40.Another: tooth crown circle diameter 14, root circle diameter about 12 (error is not more than 0.2, too small, bad amount), tooth number 31,Unit mmHow do you calculate the diameter of the pitch circle? What are the modulus of the two gears?Teach me what you know,Thank you very much for your answer. The gear is very small. Is it the same as the big gear? How much is the error?
Not all the modulus of the gear is the standard modulus
Pitch diameter = tooth number * modulusThat is, the diameter of the pitch circle is =40*24/ (40+2) =22.86Please calculate the pinion
Modulus = addendum circle diameter / (tooth number +2)That is, m=24/ (40+2) =4/7=0.57
