一、基本概念中心距离不远的两根平行轴,设计上总是用一对正齿轮来传动,一个齿接着一个齿回转,但是回转时还觉得有些震动,因此设计师们常用螺旋伞齿轮来代替正齿轮。这样,第一个齿还没有回转完毕,第二个齿早就接上,使运转圆滑,减少了震动。同样,两轴垂直成90°时,亦以用螺旋伞齿轮为佳,除了上述优点外,并可传遞较大的马力。所以螺旋伞齿轮在机械制造上的应用,越来越广泛。但螺旋伞齿轮切齿的专门机器,结构复杂,
First, the basic concept of Not far from the two parallel axes, the design is always driven by a pair of spur gear, a tooth followed by a tooth rotation, but still feel some vibration when turning, so designers often use spiral bevel gear to Instead of spur gear. In this way, the first tooth has not finished rotating, the second tooth has long been connected, so that the operation is smooth, reducing the vibration. Similarly, when the two axes are perpendicular to each other at 90 °, helical bevel gears are also preferred. In addition to the above advantages, larger horsepower can be transmitted. Therefore, spiral bevel gear manufacturing applications, more and more widely. However, special spiral helical bevel gear cutting machine, complex structure,
