宇雕手扳葫蘆省力原理
手扳葫蘆是(shì)通過人力扳動手柄借助杠杆原理獲得與負載相匹配的直線牽引(yǐn)力(lì),輪換地作用於機芯內(nèi)負載(zǎi)的一個(gè)鉗體,帶動負載運行。手扳葫蘆一種輕小型理想的手動起重工具(jù),自重輕,工作級別高,安全性能好,工作噪音低(dī),製(zhì)動力矩大等特點。河北宇雕詳細(xì)講解;手扳葫蘆(lú)的省力原理(lǐ),用動滑輪拉物體,繩(shéng)子的兩邊受(shòu)力是相等的,且均為(wéi)所牽引物理重力的一半,而人隻需要拉其(qí)中的一邊,故人隻需承受物體一半的重力,而另一半的重力則由繩的另一端所固定的物體所承(chéng)受。其實也就是力矩平衡的一個方法,增大力矩就可以減少力,也就是經常所說的(de)杠杆原理。
宇雕手扳葫蘆特點(diǎn):
1獨特的彈性離合器技術,可在任(rèn)意高度吊起貨物
2輕盈的手拉裝置、起升率高
3新型設計的鍛打式吊鉤,吊鉤頂端更為(wéi)安全,且具有緩慢彎曲性能
