裝載機http://m.lcsqtax.cn/雙圓弧齒輪傳動在工作時，從一個端面看，先是主動輪齒的凹部推動從動輪齒的凸部，離開后，再以它的凸部推動對方的凹部，故雙圓弧齒輪傳動在理論上同時有兩個接觸點。裝載機經(jīng)跑合后，雙圓弧齒輪傳動實際上有兩條接觸線，因此可以實現(xiàn)多對齒和多點嚙合。
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.

由于裝載機http://m.lcsqtax.cn/其齒根厚度較大，雙圓弧齒輪傳動不僅承載能力比單圓弧齒輪傳動約高30%以上，而且傳動較平穩(wěn)，振動和噪聲較小，并且可用同一把滾刀加工相配對的兩個齒輪。裝載機高速重載時，雙圓弧齒輪傳動有取代單圓弧齒輪傳動的趨向。
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.
