friction pulley

基本解釋

Pulley and pull rod can be moved easily without friction noise, and can be positioned anywhere;
滑輪拉桿，移動(dòng)靈活，無(wú)摩擦響聲，可于任意位置定位；
It shows that the elastic modulus and the molecular component of friction coefficient of the pulley material have great influence on the wear resistance of wire rope.
結(jié)果表明，繩輪材料的彈性模量和摩擦系數(shù)分子分量，對(duì)鋼絲繩耐磨性能有很大影響。
So, in the static state, because of the self-locking phenomenon arose by friction, no matter how exert heavy axial force on pulley it is impossible to make the work radius of the belt changed;
這樣，在靜止時(shí)，由于摩擦產(chǎn)生自鎖，在帶輪軸向無(wú)論施加多大的力，也無(wú)法使皮帶工作半徑變化；
