Abstract


The circular arc gear is one kind of high bearing capacity power drive gear. Circular arc gear as a result of its tooth profile characteristic, thus has the very high contact strength and flexural strength. At present uses the circular arc gear all is the normal circular arc gear. So-called normal circular arc gear, refers is with it conjugate basic gear-rack plane of normal section tooth profile is the curve —basic tooth profile curve which several sections of circular arcs curves organically is connected constitutes. Because the normal section tooth profile of basic gear-rack is the circular arc curve, the normal circular arc gear has two malpractices that are the sensitivity of theoretically contact position to inaccuracy to be too big and the insufficient gear flexural strength. In the literature Quasi-transverse-circular-arc Gear is precisely proposes under such background.This article is takes fashioned principle according to the cutting tool machining to aim at Quasi-transverse-circular-arc Gear to carry on the three dimensional parameterize modeling. First by the meshed principle to obtain Quasi-transverse-circular-arc Gear’s end surface tooth profile equation; Then
