Service HotlineThe DISC-LOCK lock nut is composed of two parts, each part has staggered cams. Due to the internal wedge design, the slope angle is greater than the nut angle of the bolt, the combination will be tightly bite into a whole, when vibration occurs. When the DISC-LOCK lock nut is staggered, the raised parts of the DISC-LOCK lock nut move with each other to generate lifting tension, so as to achieve a perfect anti-loosening effect.
The nuts in the prior art are easy to fall off during work, especially in harsh environments or environments with large vibrations. Sometimes it is necessary to add parts such as gaskets to prevent them from falling off, but they are still easy to fall off and cause harm.
Screws are a kind of fasteners commonly used in machinery, but most of the screws commonly used in the market are standard parts. The screws themselves are ordinary and have no function of preventing loosening and protecting the matrix. Therefore, in order to prevent the screws from loosening during use , Usually it is necessary to configure additional elastic washers, flat washers, etc. that are suitable for screws, and these elastic washers and flat washers are mostly metal products. During use, it is easy to wear with the body base and damage the protection of the sheet metal base. After long-term use, metal washers are easy to rust, which affects the tightening effect and appearance of screws. In addition, the use of metal washers not only increases the weight and cost, but also the assembly process is complicated and cumbersome, and the anti-loosening and anti-wear effects are not ideal. .
The gasket refers to the part between the connected part and the nut, which is generally a flat metal ring, which is used to protect the surface of the connected part from scratches by the nut and disperse the pressure of the nut on the connected part.
