【摘要】：為了滿足航空傳動(dòng)的緊湊空間設(shè)計(jì)要求,研究一種新型點(diǎn)接觸斜線齒面齒輪及其齒寬設(shè)計(jì)。根據(jù)漸開(kāi)線插齒刀方程,模擬插齒刀與工件的運(yùn)動(dòng)關(guān)系,推導(dǎo)斜線齒面齒輪的齒面方程;建立內(nèi)端根切、外端變尖、限定工作齒高和避免二次切削等限制條件,計(jì)算面齒輪的有效齒寬。分析傾斜角、交點(diǎn)位置對(duì)內(nèi)徑、外徑及齒寬的影響。研究結(jié)果表明:減小刀頂圓角半徑可避免齒根發(fā)生二次切削;增大傾斜角和交點(diǎn)位置的增量,面齒輪的內(nèi)徑和外徑都增大,而有效齒寬卻減小。
[Abstract]:In order to meet the requirements of compact space design of aeronautical transmission, a new type of point contact bevel gear and its tooth width are studied. According to the equation of involute gear shaper, the kinematic relation between gear shaper and workpiece is simulated, the tooth surface equation of bevel gear is deduced, and the limiting conditions, such as cutting inner end root, sharpening outer end, limiting working tooth height and avoiding secondary cutting, are established. Calculate the effective tooth width of the face gear. The influence of inclination angle, intersection position on inner diameter, outer diameter and tooth width is analyzed. The results show that the secondary cutting of tooth root can be avoided by reducing the radius of the fillet of the top of the cutter, and increasing the increment of the angle of inclination and the position of intersection, the inner and outer diameters of the face gear will increase, but the width of the effective tooth will decrease.
