Spring washers are often used with nuts, screws and bolts to prevent loosening.
弹垫常常配合螺母、螺丝、螺栓使用，防止松动。




GB93 spring pads can increase the preload, have the role of anti-loosening, its role is to rely on its elasticity and bevel friction to achieve. Generally used in vibration, pulse, the temperature of the medium has a relatively large fluctuations in the occasion.
GB93弹垫可加大预紧力、有防松作用，它的作用是靠其弹性和斜口摩擦来实现的。一般常用在有震动、脉冲、介质的温度有比较大的波动时的场合。





GB97 flat pad shape is a circle, mainly used to reduce the pressure, often used in conjunction with bolts, screws and nuts, GB97 can increase the contact area of the screws and machines, by the threaded fasteners material and process limitations, bolts and other fasteners supporting surface is not large, with the use of flat pads can reduce the pressure surface of the pressure surface pressure to protect the surface of the connected parts.
GB97平垫形状是一个圆圈状，主要用于减小压强，常与螺栓、螺钉及螺母配合使用，GB97可以加大螺丝与机器的接触面积，受螺纹紧固件的材料与工艺限制，螺栓等紧固件的支承面不大，配合平垫使用可减小承压面的压应力保护被连接件的表面。
