CHARACTERISTICS OF THE SILENT CHAIN
Fig. 1 Engagement of Silent Chain
Fig. 1 Silent Chain, also known as Inverted Tooth Chain, has inner links that conform to the sprocket teeth shape. The angled sides f the link teeth push against the sides of the sprocket teeth to transmit torque.
圖1．無聲，也稱為倒齒鏈，具有與輪齒形狀一 致的内鍵節。
連桿齒的成角度的面推動鍊輪齒的側面傳遞扭矩。
Fig. 2 Engaging Mechanism of Silent Chain
Fig. 2 The chain links rotate about the axis of the pin at point A and engage the involute on the sprocket teeth. Since the links slide into the sprocket at a relatively small angle, α ,the engagement is smooth and quiet.
圖2．鍊節在點A處繞銷的軸線旋轉，並嚙合鏈輪齒上的漸開線。
由於鏈節以相對較小的角度α滑入鏈輪,所以接合平穩且安靜。
Fig. 3 Engaging Mechanism of Roller Chain
Fig. 3 In contrast, Roller Chain engages the sprocket at a much greater angle than Silent Chain, α' nearly 90ﾟ. More noise is generated as the roller impacts the bottom of the sprocket tooth.
圖3．相比之下，滾子鏈與鏈輪的嚙合角度比無聲鏈條大得多，α'近似為90ﾟ。
當滾子衝擊鏈輪齒的底部時會產生更多的噪音。
Furthermore, the difference in chain construction affects the load carrying members per pitch. Additional capacity requires an increase in chain pitch or using multiple strands of roller chain.
此外，鏈條结構的差異影響每個節距的承載構件。
額外的容量需要增加鏈條問距或使用多股滾子鏈。
As a result, Silent Chain offers a drive that is
因此，無聲鏈條提供了一個驅動器
．Smoother 平滑
．Quieter 更安靜
．Higher Efficiency 更高的效率
．More Compact 更緊湊
