We can tell from its name what this product is used for with its waveform spring washer. After continuous improvement, this product has more and more functions. In order to make more people familiar with it, the Ruian waveform spring washer manufacturer will introduce the reasons for the fracture of the waveform spring washer to everyone? If you want to know, let's take a look together. I hope it can be helpful to you.
The manufacturer of Ruian waveform spring washers said that the expansion phenomenon of spring washers is generally not a problem with the spring washers themselves. Spring washers with expansion rings need to withstand radial outward tension, which comes from the tightening axial force generated by the tightening torque. The outer chamfer of the nut support surface generates a radial component of axial clamping force, which expands the opening of the spring washer. The smaller the chamfer diameter, the greater the possibility of protrusion. Adding a flat washer between the nut and spring washer can help slow down or prevent ring expansion, but a flat washer that is too thin or too soft will not prevent ring expansion. The manufacturer of Ruian waveform spring washers said that the reason for hydrogen embrittlement fracture of spring washers is generally due to unreasonable heat treatment process and failure to undergo hydrogen removal treatment in a timely manner after electroplating. A large number of experiments and long-term practical experience have confirmed the above analysis.
The manufacturer of Ruian waveform spring washers claims that spring washers can prevent loosening and increase preload, while flat washers do not have this function. Can be used to increase the tightening contact area, prevent friction between bolts and workpieces, and protect the surface of connectors to prevent bolts from falling off. Scratches on the surface of the workpiece when tightening the nut.
However, for some important connections, such as those that rely mainly on compression to generate friction to transmit power, spring pads cannot be used, as the stiffness of the connection decreases and accidents are prone to occur. Spring washers can be omitted. The manufacturer of Ruian waveform spring washers said that when the strength of the connectors is low, flat washers or flange bolts can be used to increase the contact area. When there is vibration, pulse, or significant temperature fluctuations in the medium, spring washers need to be used. Spring washers can prevent loosening and increase preload, while flat washers do not have this function. The manufacturer of Ruian waveform spring washers said they can be used to increase the tightening contact area, prevent friction between bolts and workpieces, and protect the surface of connecting parts to prevent bolts from falling off. Scratches on the surface of the workpiece when tightening the nut.
