裝載機(jī)http://m.hdwzhs.com/雙圓弧齒輪傳動(dòng)在工作時(shí)，從一個(gè)端面看，先是主動(dòng)輪齒的凹部推動(dòng)從動(dòng)輪齒的凸部，離開(kāi)后，再以它的凸部推動(dòng)對(duì)方的凹部，故雙圓弧齒輪傳動(dòng)在理論上同時(shí)有兩個(gè)接觸點(diǎn)。裝載機(jī)經(jīng)跑合后，雙圓弧齒輪傳動(dòng)實(shí)際上有兩條接觸線，因此可以實(shí)現(xiàn)多對(duì)齒和多點(diǎn)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(jī)http://m.hdwzhs.com/其齒根厚度較大，雙圓弧齒輪傳動(dòng)不僅承載能力比單圓弧齒輪傳動(dòng)約高30%以上，而且傳動(dòng)較平穩(wěn)，振動(dòng)和噪聲較小，并且可用同一把滾刀加工相配對(duì)的兩個(gè)齒輪。裝載機(jī)高速重載時(shí)，雙圓弧齒輪傳動(dòng)有取代單圓弧齒輪傳動(dòng)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.
