In the conventional silent 對齒廓的關(guān)節(jié)答:在傳統(tǒng)的沉默 chain the right tooth profile of the joint A is the outer tooth 合適的齒廓的鏈的聯(lián)合是外面的牙齒 profile of the link 1. But in the dual meshing silent chain the 剖面的鏈接1。但在雙重嚙合沉默鏈 right tooth profile of the joint A is the inner tooth profile of 對齒廓的關(guān)節(jié)一個內(nèi)在的齒廓的 the link 2. Because the inner tooth profile of link plate is 鏈接2。因為內(nèi)在齒廓的連接板 profiled to parallel and project outward of the outer tooth 嚴密,平行和項目外的外的牙齒 profile as the dual meshing silent chain is stretched into a 剖面作為雙嚙合沉默鏈是深入到各行各業(yè)的一個 line. So in the dual meshing silent chain drive, the tight side 線。所以在雙重嚙合沉默鏈傳動,緊的一面 of the chain can still be tangential to the sprocket pitch circle 的鏈條仍然可以切向的鏈輪節(jié)圓 at the position shown in the Fig.1 (a) by defining the special 在圖1中所示的位置(a)定義了特別的 relation about the inner and outer tooth profile.

Because of the static characteristics of 多邊形的行動。因為靜態(tài)特性的 chain drive, the position of joint A is influenced by that of 鏈傳動,關(guān)節(jié)的位置的一個影響是由 joint B. Thus the parameter f is also related to the movement 因此該參數(shù)的聯(lián)合b . f也與運動 distance of the tight side when the center of the joint A keeps 緊密的球隊以距離的中心聯(lián)合一個保存 on the line tangential to the sprocket pitch circle[5]. So the 在線上的切向的鏈輪節(jié)圓[5]。所以 parameter f may be satisfied with some condition to make 參數(shù)f感到滿意,使一些條件 the inner tooth profile and the outer tooth profile all mesh 內(nèi)在的齒廓與外齒廓的網(wǎng)格 with the sprocket tooth. 與鏈輪齒。 Fig.1 Theory of reducing the polygon action 圖1理論減少多邊形的行動 B.
