犹如格里生制零度伞齿轮,将圆柱齿轮牙齿亦制成圆弧齿,即构成平行轴传动的圆弧齿线齿轮。照例可用简单的直线形刀刃、端面镶齿的刀盘进行展成加工,而使此种齿轮在中央截面获得正确的渐开线齿廓。显然,此种齿轮传动能保持瞬时速比不变,且无轴向力;并因重合系数提高,一对牙齿是逐渐进入和退出啮合,使得传动平稳;其共轭齿面沿接触线成为一凸一凹密切接触、齿面接触线加长、齿廓诱导法曲率减小,提高了齿面接触强度;此外,圆弧齿线齿轮越远离中央截面齿根越益增厚、且齿根能采用成形法切削,既可避免根切又可 Just like Grievances zero gear bevel gear, the cylindrical gear teeth are also made of arc teeth, which constitute the parallel axis drive arc gear. As an example, simple straight-edged blades and end-faceted cutterheads can be used to create the correct involute profile at the center cross-section. Obviously, this kind of gear drive can keep the instantaneous speed ratio unchanged, and no axial force; and due to the coincidence coefficient increases, a pair of teeth is gradually entering and exiting meshing, making the transmission stable; the conjugate flank along the contact line to become a Convex contact with a concave close contact with the tooth surface contact line lengthened tooth profile induced curvature decreases, to improve the contact strength of the tooth surface; In addition, the arc tooth gear more away from the central cross-section tooth roots thicker, and the root can be used Forming cutting, both to avoid radical and can
