        棘輪扳手與扭力扳手的區別

        1.一種手動(dòng)螺絲松緊工具,單頭、雙頭多規格活動(dòng)柄棘輪梅花扳手(固定孔的)。是由不同規格尺寸的主梅花套和從梅花套通過(guò)鉸接鍵的陰鍵和陽(yáng)鍵咬合的方式連接的。由于一個(gè)梅花套具有兩個(gè)規格的梅花形通孔,使它可以用于兩種規格螺絲的松緊,從而擴大了使用范圍,節省了原材料和工時(shí)費用?;顒?dòng)扳柄可以方便地調整扳手使用角度。這種扳手用于螺絲的松緊操作,具有適用性強,使用方便和造價(jià)低的特點(diǎn)。     

        2.扭矩扳手-也叫扭力扳手或力矩扳手,力矩就是力和距離的乘積,在緊固螺絲螺栓螺母等螺紋緊固件時(shí)需要控制施加的力矩大小,以保證螺紋緊固且不至于因力矩過(guò)大破壞螺紋,所以用扭矩扳手來(lái)操作。首先設定好一個(gè)需要的扭矩值上限,當施加的扭矩達到設定值時(shí),扳手會(huì )發(fā)出“卡塔”聲響或者扳手連接處折彎一點(diǎn)角度,這就代表已經(jīng)緊固不要再加力了。

        3.它們的區別在于,扭矩扳手的力矩可以設定。
