齿轮轴和轴承的弹性变形以及齿间和轴承间的滑动摩擦均会导致精密渐开线齿轮产生强迫振动,采用减小齿轮轴有效跨度,或/和增大齿轮轴直径,或/和降低齿间和轴承间滑动摩擦系数,或/和减小轴承间隙,或/和增加齿轮模数,或/和保持齿数比不变条件下增加齿数等措施可有效地抑制齿轮的强迫振动。 Elastic deformation of the gear shaft and bearing, as well as sliding friction between the teeth and the bearing, can result in forced vibration of the precision involute gear by reducing the effective sprocket shaft span or / and increasing the gear shaft diameter or / Forced vibration of gears can be effectively suppressed by sliding friction coefficient between bearings and / or bearing clearance reduction, and / or increasing the gear modulus or / and increasing the number of teeth under the same gear ratio.
