Nuts and screws are things that we often use in our daily lives. There are many kinds of nuts. Ordinary nuts often loose or fall off automatically due to some external forces during use. In order to prevent this phenomenon, people rely on their own ingenuity to invent the self-locking nut we are going to talk about today. In this way, the function of the lock nut is clear at a glance, that is, it can resist vibration, loosening and falling off. A nut is a nut, a part that is screwed together with a bolt or screw for fastening.
Anti-loosening method: The anti-loosening nut is the nut, which is screwed together with the bolt or screw to be used for fastening. It is an original part that all production machinery must use. The anti-loosing nut is the part that closely connects the mechanical equipment. , Through the inner thread, the lock nut and screw of the same specification can be connected together. Since the lock nut stopper has no pre-tightening force, the anti-loosening stopper only works when the lock nut is loosened to the stop position. Therefore, the lock nut does not prevent loosening in practice but avoids falling.
Rivet nuts are now widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, shipbuilding, air conditioners, elevators, meters, furniture, buildings, etc. Rivet nuts have been widely used in foreign locomotives, and have also been successfully used in my country’s Harmony HXD1 electric locomotive. The application of rivet nuts on HXD1 locomotives is a 2-6mm thin plate structure, which is mainly used for the installation of small parts. The axial load and torsional load are not large, and a large number of them are required in a small area. Bolted.
