现在,造船工业最通行的二个轮齿弯曲应力计算方法是: 1.按MIL-G-17859计算齿根应力; 2.单位负荷法。早在1909年,当透平齿轮第一次应用到船上时,已经介绍了这二个方法,而在50年代中期则正式应用到船用齿轮上。在1916年至1940年期间,推进齿轮的承载能力是由经验公式来决定的,它等于单位齿宽负荷与常数和小齿轮直径乘积之比。常数的范围在50至60之间。直径取一次方,有时也取1/2次方或2/3次方。 1941年,海军齿轮工业委员会和海事管理署采取了这样一个公式,即直径d定为一次方,并
Now, the two most common bending stresses in the shipbuilding industry are: 1. Calculate the root stress according to MIL-G-17859; 2. The unit load method. As early as 1909, the two methods were introduced when the turbine gear was first applied to the ship, and was officially applied to the marine gear in the mid-1950s. Between 1916 and 1940, the carrying capacity of the propulsion gear was determined empirically, which was equal to the ratio of the unit tooth width load to the constant and the diameter of the pinion. The range of constants is between 50 and 60. Take the diameter of the first party, and sometimes take 1/2 or 2/3 power. In 1941, the Navy Gear Commission and the Maritime Administration took the formula that the diameter, d, is a square and
