目前的蜗轮轮齿齿根强度是按齿根的弯曲强度计算的,其原理是把轮齿视为悬臂梁,危险截面为齿根截面,用悬臂梁的强度条件推导出齿根的弯曲强度计算公式。直齿轮和蜗轮二者的区别仅仅是前者的危险截面为一平面矩形截面,后者为一弯曲矩形截面。用于各种不同机器中的蜗轮付,其损坏的原因除了胶合、点蚀外,主要是齿面磨损严重,使轮齿变得很薄,最后导致不能正常啮合而损坏,可以说基本上没有发生过因为齿根的抗弯强度不足而产生齿根折断的现象。与此相
The current root strength of the worm wheel gear is calculated according to the bending strength of the root, the principle is to consider the gear teeth as a cantilever beam, the dangerous cross section is the tooth root section, and calculate the bending strength of the tooth root using the strength condition of the cantilever beam formula. The difference between a spur gear and a worm gear is only that the dangerous cross section of the former is a plane rectangular cross section and the latter is a curved rectangular cross section. Used in a variety of different machines to pay the worm, the reason for the damage in addition to gluing, pitting, the main tooth surface is severely worn, so that the gear becomes very thin, the final result can not be properly engaged and damaged, it can be said that basically no Occurred because the root of the flexural strength of the root degeneration caused by the phenomenon. And this phase
