Bevel gear calculation card

-- 2010-06-09

Bevel gear design and calculation of number: 168 044 *
Note: This procedure applies to GLEASON bevel gears and gear system, a small gear is greater than or equal to 12 spiral bevel gear (including zero bevel gears).
              Tolerance value is the midpoint method in accordance with the module from 1 to 10 mm, the midpoint of pitch circle diameter of 400 mm, precision grade 5,6,7,8-level set.
              Spiral bevel gear cutter set 3.5,6,7.5,9,12,18 inches in diameter. Geometric parameters can be calculated and the carrying capacity of checking (the working conditions of the original
              Motivation even smooth, vibration from the motive medium), spiral bevel gears can be processed on the feasibility of (cutter selection) to judge.
Reference standard: GB11365 - 89 bevel gear and hypoid gear precision, GB10062 - 88 Calculation of load capacity bevel gear
Main Reference: "Gear Guide" on the next book, "Machine Design Manual" 2 on the books, "complex tool design handbook" second volume
Programming: Deng Shijun 2001.05
Note: This program has "Single Variable", from Tools - Options - set the repeated recalculation operation, up to 10,000 iterations, the maximum error of 0.0001.
