The meshing line of a pair of klingelnberg bevel gears 克林貝格錐齒輪的嚙合線
It was pointed out that the actual center - line and theoretic meshing line of the paired gears varied in the form of planar motion due to the system vibration , and the actual meshing line was curvilinear 結(jié)果表明,由于系統(tǒng)振動的原因,齒輪副的實(shí)際中心線和理論嚙合線是以平面運(yùn)動方式變化的,實(shí)際嚙合線(即嚙合點(diǎn)的軌跡)是一條曲線。
By analyzing the vibration movement of the gear system , the actual center - line equation and that of the theoretic meshing line were derived in their vibration condition , and their movements and the modality of the actual meshing line was analytically verified 摘要根據(jù)齒輪系統(tǒng)的振動運(yùn)動,建立了在振動條件下齒輪副實(shí)際中心線方程和理論嚙合線方程,分析論證了實(shí)際中心線和理論嚙合線的運(yùn)動及實(shí)際嚙合線的形態(tài)。
