    摘要:

    根據(jù)空間齒輪嚙合原理,提出一種偏心—高階橢圓錐齒輪副的設(shè)計(jì)方法,建立了偏心—高階橢圓錐齒輪副的數(shù)學(xué)傳動(dòng)模型,推導(dǎo)出偏心橢圓錐齒輪和與其相互嚙合的高階橢圓錐齒輪的節(jié)錐面、球面節(jié)曲線方程;分析了范成法生成偏心—高階橢圓錐齒輪齒廓的過程,獲得了范成刀具的空間走刀位置;結(jié)合VB與Solidworks(API),開發(fā)出偏心—高階橢圓錐齒輪仿真加工設(shè)計(jì)程序,得到了偏心—高階橢圓錐齒輪副的虛擬實(shí)體及其裝配模型;通過對(duì)偏心—高階橢圓錐齒輪副傳動(dòng)特性的分析,得到了偏心—高階橢圓錐齒輪副傳動(dòng)過程中傳動(dòng)比、從動(dòng)輪角速度和角加速度的變化規(guī)律。

    Abstract:

    Base on the space engagement theory, a design method of eccentric—high order elliptical bevel gear pair was presented, the mathematical model of eccentric—high order elliptical bevel gear drive was established, pitch cone and spherical pitch curve of the eccentric elliptical bevel gear and the high order elliptical bevel gear were derived; the position of the cutter in the space during tooth profile of eccentric—high order elliptical bevel gear was generated analyzed. Secondary development based on Solidworks (API) and VB, which made the pseudoentity and assembly model of eccentric—high order elliptical bevel gear pair was obtained; and then the transmission characteristics of eccentric—high order elliptical bevel gear pair was analyzed,the change laws of eccentric—high order elliptical bevel gear pair, angular velocity and angular acceleration of driven wheel during the transmission were acquired.
