Knowledge about nylon self-locking nuts

Introduction to nylon self-locking nuts:

Nylon self-locking nut is a new type of high-vibration and anti-loosening fastening parts, which can be used in various mechanical and electrical products at a temperature of -50~100℃.

The working principle of nylon self-locking nuts:

During the installation of the nut pair, the thread of the bolt squeezes the nylon embedded in the nut, causing the nylon to deform. After installation, the nylon and the thread are completely in squeeze contact, and the squeezed nylon produces a very strong impact on the bolt. The large resilience force increases the friction. This force makes the bolts not easy to loosen. The nylon itself is acid and alkali resistant, and the nut is made of stainless steel.

Nylon self-locking nut link method:

The link method of nylon self-locking nuts is to install a self-locking nut with a nylon ring on the connecting piece, and use the elastic amount of the nylon ring to realize the self-locking connection between the connecting pieces; at the same time, the self-locking nut and the connecting piece are used The anti-rotation connection prevents the self-locking nut from slipping when the bolt is screwed.

The basic structure of nylon self-locking nuts:

The basic structure of a nylon self-locking nut consists of: a nut shell, one end of the threaded hole of the nut shell is provided with a ring groove; a nylon ring is provided in the ring groove; the other end of the nut shell is provided with a riveting joint; a riveting joint Riveting with the riveting hole on the connecting piece. The nylon self-locking nut has a simple structure and is very convenient to operate. It is especially suitable for occasions with narrow spaces for automobiles and aviation lights and high connection reliability requirements.

Main application of nylon self-locking nuts:

It is mainly used in aerospace, aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products and all kinds of machinery. The demand for nylon self-locking nuts has increased sharply because of its anti-vibration The anti-loose performance is much higher than other various anti-loose devices, and the vibration life is several times or even dozens of times longer. At present, more than 80% of the accidents of mechanical equipment are caused by the loosening of fasteners, especially in mining machinery. The use of nylon self-locking nuts can prevent major accidents caused by loosening of fasteners.
