渐开线点啮合齿轮传动,是一种点线啮合的新型齿轮传动,其小齿轮为渐开线变位的特殊短齿,其大齿轮为具有部分渐开线的凸齿和过渡曲线的凹齿廓所组成。它们相互啮合时,既形成线接触又能够同时形成点啮合,实现点线啮合传动。其重合度比点啮合齿轮大,接触强度和弯曲强度高,而且加工制造方便,因而能够普遍推广和应用。 Involute point meshing gear drive is a new line of gear meshing gear, the pinion involute special short tooth displacement, the gear is a part of involute convex and transition curve concave Composition of tooth profile. When they are engaged with each other, they not only form a line contact but also form a point engagement at the same time, so as to realize point-line engagement transmission. Its coincidence than the meshing gear, contact strength and bending strength, and easy processing, which can be widely promoted and applied.
