装载机双圆弧齿轮传动多点啮合

装载机http://www.sdyongbaojixie.com/双圆弧齿轮传动在工作时，从一个端面看，先是主动轮齿的凹部推动从动轮齿的凸部，离开后，再以它的凸部推动对方的凹部，故双圆弧齿轮传动在理论上同时有两个接触点。装载机经跑合后，双圆弧齿轮传动实际上有两条接触线，因此可以实现多对齿和多点啮合。
Loader double arc gear at work, from one end, the recess first initiative to promote tooth tooth driven protrusion, left, then push it the other protrusion recess, so double arc gear in theory, there are two points of contact simultaneously. After running-loaders, the double arc gear actually has two contact lines, so you can achieve more and more of teeth meshing points.

由于装载机http://www.sdyongbaojixie.com/其齿根厚度较大，双圆弧齿轮传动不仅承载能力比单圆弧齿轮传动约高30%以上，而且传动较平稳，振动和噪声较小，并且可用同一把滚刀加工相配对的两个齿轮。装载机高速重载时，双圆弧齿轮传动有取代单圆弧齿轮传动的趋向。
Due to the thickness of the tooth root loader its large double arc gear carrying capacity of only a single arc gear transmission ratio of about 30% higher, and drive more stable, less vibration and noise, and can be processed in the

same match on the hob two gears. When high-speed heavy loaders, double arc Gear replace single-arc Gear trend.
