液压螺栓预紧力有效控制的五大招

日期:2019-04-16

螺栓是机械上常用的紧固件之一,而螺栓的预紧力与使用性能有这亲近的联系,螺栓预紧力联系到被衔接件的紧密型和可靠性,过大或者过小的预紧力都会对衔接质量产生影响。如螺栓预紧力过大,会呈现超拧现象;螺栓预紧力过小,则确保不了衔接强度与质量。

拧紧力与螺栓预紧力呈线性联系在,操控了拧紧力矩的大小,就能够经过试验或理论计算的办法得到预紧力值。但在实际中,因为受摩擦系数和几许参数误差的影响,在必定的拧紧力矩下,预紧力变化比较大,故经过拧紧力矩来操控螺栓预紧力的精度不高,其误差约为±25%,最大可达±40%一般来说,操控区拧紧力矩精度较高的东西是测力矩扳手和限力扳手。
