**度螺栓是用特制的扳手上緊螺帽，使螺栓產(chǎn)生巨大而又受控制的預(yù)拉力，通過(guò)螺帽和墊板，對(duì)被連接件也產(chǎn)生了同樣大小的預(yù)壓力。在預(yù)壓力作用下，沿被連接件表面就會(huì)產(chǎn)生較大的摩擦力，顯然，只要軸力小于此摩擦力，構(gòu)件便不會(huì)滑移，金屬螺釘規(guī)格，連接就不會(huì)受到破壞，金屬螺釘規(guī)格，這就是**度螺栓連接的原理。 **度螺栓連接是靠連接件接觸面間的摩擦力來(lái)阻止其相互滑移的，為使接觸面有足夠的摩擦力，金屬螺釘規(guī)格，就必須提高構(gòu)件的夾緊力和增大構(gòu)件接觸面的摩擦系數(shù)。先進(jìn)螺栓是機(jī)械制造之本。金屬螺釘規(guī)格</p><div style="width:100%;text-align: center;"><img
