摘　　要：以新一代航空发动机传动系统等为代表的高端传动装备面临高速、高温、重载等极端服役环境挑战,使得胶合失效成为齿轮主要失效形式之一,严重影响系统寿命和可靠性。针对国内常用的3个齿轮胶合评价标准在齿轮胶合承载能力计算结果之间差异较大,且标准公式适用范围存在差异的问题,详细研究了闪温法和积分温度法,从理论分析、公式对比和案例分析三个方面开展了渐开线圆柱齿轮胶合承载能力标准对比研究;并针对FZG A型齿轮,进行了对比计算分析。结果表明,由于HB/Z 84.4的平均摩擦因数计算结果偏高,与GB/Z 6413.2相比计算结果偏大,HB/Z 84.4结果偏保守。GB/Z 6413.1和GB/Z 6413.2在较大的转矩、油温、转速范围内,齿面温度计算结果相差不大;但是,随着模数的减小,二者的齿面温度计算结果差异变大;模数在4~7 mm内,二者齿面温度计算结果相差不大。The high-end transmission equipment such as the new generation of aero-engines faces the challenge of extreme service environments such as high speed,high temperature and heavy load.Scuffing failure is one of the main failure modes of gears,which seriously affects life and reliability.The common Chinese gear scuffing design standards include GB/Z 6413—2003 and HB/Z 84.4—1984.However,the calculation results of these standards for the scuffing loading capacity of gears are different,and difference exists in the application scope of these formulae.Thus,a comparative study of the cylindrical involute gear scuffing capacity standards based on GB/Z 6413 and HB/Z 84.4 is carried out from three aspects:theoretical analysis,parameter comparison and case studies.For FZG A type gears,dozens of case groups have been calculated.The results show that the calculated average friction coefficient of HB/Z 84.4 is higher than that of GB/Z 6413.2,and the calculated results of HB/Z 84.4 are conservative.It is found that calculation results of the surface temperature of GB/Z6413.1 and GB/Z 6413.2 are consistent in a large range of torque,oil temperature,and speed.However,the difference in the tooth surface temperature of the two methods becomes larger as the tooth module decreases.The temperature results are generally consistent with each other as the tooth module lies within the range of 4-7 mm.
