摘　　要：吊车臂架的回转机构通常采用大齿圈和小齿轮的啮合来实现其回转运动。利用KISSsoft建立回转机构组件及齿轮副模型,在考虑齿轮轴组件受力和变形对齿轮副啮合的影响下,以降低齿轮副间隙差值和齿向载荷分布系数,以及提高齿轮的传动性能为目标,对啮合的小齿轮首次采用了固定的鼓形修形值和变化的螺旋线修形值相结合的方式进行修形。并提出了全新的迭代试凑法来确定螺旋线修形值,使得齿轮副齿面峰值应力下降,缓解了应力沿齿宽方向分布不均现象。解决了大型回转机构齿轮副的断齿问题,减小了偏载对齿轮传动的影响,不仅提高了齿轮的传动性能,延长了使用寿命,还具有很好的工程参考价值。The rotary mechanism of crane boom usually adopts meshing of big gear ring and pinion to realize its rotary motion.By using the KISSsoft to establish the rotary mechanism assembly and gear pair model, considering the influence of the force and deformation of the gear shaft assembly on the gear pair meshing, the aim is to reduce the gap difference between the gear pair and the tooth direction load distribution coefficient, and to improve the transmission performance of the gear. For the first time, the method of combining the fixed drum shape modification value with the changing spiral shape modification value was used to modify the meshed pinion. A new iterative trial-and-try method was proposed to determine the helical modification value of pinion gear, which makes the peak stress of the gear pair surface decrease and alleviates the uneven distribution of stress along the tooth width direction. It solves the problem of tooth breakage of gear pair of large rotary mechanism, reduces the influence of bias load on gear transmission, not only improves the transmission performance of gear,prolongs service life, but also has good engineering reference value.
