大多数齿轮的损坏是由于高的接触(赫兹—Hertz)应力和弯曲应力所造成,开槽的轮齿能使这些应力降低并获得机器的平静运转。机械设计中,相啮合的零件具有两种接触形式——面接触和点接触。面接触是两个物体在有限的接触面积上,所有点同时接触;而点接触只是在某一点接触。接触区域局限于点或线时,必须用弹性理论来做部分分析。弹性理论和赫兹理论是近似的。这是假定接触面积比接触点的曲率半径小。这种现象在齿轮、轴承、螺纹、滚筒以及其
Most gear damage is caused by high contact (Hertz-Hertz) stresses and bending stresses, and the notched gear teeth reduce these stresses and achieve a smooth machine operation. Mechanical design, the meshing parts have two forms of contact - surface contact and point contact. Surface contact is two objects in a limited area of contact, all points at the same time contact; and point contact is only at a certain point of contact. When the contact area is limited to points or lines, it must be partially analyzed using elastic theory. Elasticity theory and Hertz theory are approximate. This assumes that the contact area is smaller than the radius of curvature of the contact point. This phenomenon in gears, bearings, threads, rollers as well
