Six basic methods of anti-loosing flat washers do you know a few-hardware

How to tighten a small nut has always been an enduring topic in mechanical design, and everyone knows better, such as Japanese eccentric nuts, Down nuts and Chinese self-tightening wang nuts. But we will not talk about these stars in the fastener industry today, let's talk about the most basic method of tightening the anti-loosening flat washer at work. Flat washer The washer refers to the part that is cushioned between the connected part and the nut. Generally, a flat metal ring is used to protect the surface of the connected part from being scratched by the nut and disperse the pressure of the nut on the connected part. Flat washers and spring washers Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and convenient installation, and are suitable for parts with frequent assembly and disassembly. But the anti-loosening ability of spring washers is very low! Self-locking nuts Normal nuts will loosen due to vibration and other reasons during use, such as vibration. In order to prevent this phenomenon, self-locking nuts were invented. The function of the self-locking nut is mainly to prevent loosening and vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with embedded nylon rings, those with neck closure, and those with metal anti-loosening devices. They are all effective torque type locknuts. Due to its nature, self-locking nuts are more difficult to screw. Double nuts (left and right rotation) anti-loosening To match a zuo screw nut and a right-hand screw nut to tighten and anti-loosing, this is also a good method. Screws and nuts are drilled and fixed with pins. In machinery, pins are mainly used for assembly and positioning, and can also be used as overload shear connections in connection and relaxation-level devices. The types of pins are: cylindrical pin, tapered pin, pin with hole, split pin and an all pin, etc. Also need to know the knowledge of anti-loose flat washers, please call:
