摘要: 在齿面上钻小孔,埋导线,用电接触法测得通电时和断电时的齿轮转角,换算成瞬时接触迹宽度。对不同螺旋角和不同载荷时测得的接触迹宽度拟合成公式,续而推导出接触应力公式。又用一批齿轮作疲劳试验,得到接触疲劳极限应力,它与应力公式配套,可用于JB2940-81齿形的双圆弧齿轮的接触疲劳强度计算。

Abstract: In this paper a new electrical method has been developed for measuring the width of instantaneous contact locus for the helical gears with double-circular-arc tooth profile.The formula of width of contact locus may be derived through regression analysis of different width of contact locus obtained from different helical angles and loads of the gears. Afterwards we have derived the for-mula of contact stress based on the formula of width of contact locus. The endurance limit for contact stress was obtained from the fatigue test of a set of gears. Both contact stress formula and endurance limit stress together may be used for calculation of surface durability of this kind of gears in basic profile JB2940-81.
