常见车用柴油机螺纹紧固件的防松方式主要有以下4种。一是摩擦防松这是应用最广泛的一种防松方式,这种方式在螺纹副之间产生一个不随外力变化的正压力,以产生一个可以阻止螺纹副相对转动的摩擦力。这种正压力可通过轴向或同时两向压紧螺纹副来实现。如采用弹性垫圈、双螺母、自锁螺母和尼龙嵌件锁紧螺母等。这种防松方式对于螺母的拆卸比较方便,但在冲击、振动和变载荷的情况,一开始螺栓会因松弛导致预紧力下降,随着振
Common vehicle diesel threaded fastener locking methods are the following 4 kinds. First, friction and anti-loose This is the most widely used anti-loosening method, this way between the screw pair produces a positive pressure that does not vary with the external force to produce a friction that can prevent the relative rotation of the screw pair. This positive pressure can be achieved either by axial or simultaneous biasing of the thread pair. Such as the use of elastic washers, double nuts, self-locking nuts and nylon inserts lock nut. This method of loosening nut for the more convenient demolition, but in the impact, vibration and variable load situation, the beginning of the bolt will be due to relaxation caused by preload reduction, with the vibration
