平垫是增大接触面,不起防松作用,弹垫可以
平垫圈是为了保护安装面。
弹性垫圈是为了防松,是用斜口咬住安装面来防松的,当然也能用变形的预紧力防松,它容易划伤安装面。
设计时,两者只用一个,两个都用防松效果打折扣,只是弹性垫圈给的一点预紧力。

平垫圈本身比较软,在拧紧时垫圈本身发生形变来防松的,

弹性垫圈和蜾母---不能重复使用,
平垫圈也不能重复使用
螺母也不能重复使用吗?
我平时3种都重复使用。&

好像现在弹垫和平垫一起用的也很多?
不是路过,专业学习来自: Android客户端
平垫圈主要是为了增加接触面积减少表面压强,楼上说平垫圈有可能在拧紧时出现变形,那这样的平垫圈就算失效,要么减小预紧力,要么平垫圈换材料,通常在联接中平垫圈变形是不允许的。弹垫具有防松性能,但防松性能一般。
怎么能算失效呢,平垫圈与材料的接触面并没有变形啊&

能帮我解释一下红本价、蓝本价是什么意思
扫二维码下载作业帮
拍照搜题,秒出答案,一键查看所有搜题记录
通俗讲,红本价是指行业里碳钢的牌价,白本价是指不锈钢的牌价;以上价格表是由上标集团出版,在行业影响广泛,故以此牌价的下浮和上涨作为交易的参考.比如说,弹垫下40,就指按照牌价下浮40%,等于是6折为交易双方的价格.   “红本价”的全称是“上海市机电产品出厂价格目录”,该目录共11册.   第一册是机床、机床附件产品;   第二册是重型、矿山机械、通用、石化机械产品;   第三册是轻工、印包、林业机械;   第四册是电机、电站设备;   第五册是电线、电缆;   第六册是电器;   第七册是拖拉机、汽车及配件;   第八册是标准紧固件;   第九册是电焊条、焊割具、工具、量具、刃具、磨具、磨料产品;   第十册是液压、气动元件;   第十一册是轴承产品.   由于该目录出版时封面印刷成红色,故称之为“红本价”. 蓝本 …………不晓得,只是它可以作为行业的一个基价
