Screws can be found everywhere in daily life, although it is a very small part, but it is very important. If loosened, the consequences will be unpredictable. Today, Aozhan hardware manufacturers share with you a few ways to deal with screws to prevent loosening.
1. Use Flat / spring washers
Flat washer to do to avoid the bolt nut locking a part, in the use of fasteners in the region basically have to use flat washers, flat washers key to increase the contact surface between the product and tighten the efficacy, according to expand the contact surface, can reduce the damage caused by friction between parts, but also to reduce the nut and machinery and equipment in the middle of the pressure, which in turn has a cushioning effect.
The spring washer has a good anti-loosening performance and anti-vibration effect. The general thread direction is right-handed, while the spring washer spiral direction is left-handed, in the torsion of the nut, relying on the washer flattening and the elastic reaction force between the screwed threads to tighten. In the case of very large dynamic load, and its bearing vibration load, we can use flat washers and spring washers.
In addition to pop washers and flat washers, as well as various styles of sealing washers, can also be used as needed. Adding washers can increase friction and cushioning, maintaining the surface of the coupled parts will not be rubbed by the nut, divide the pressure of the nut on the coupled parts.
2. Use lock nuts
Locking nuts are generally locked by sliding friction, and are usually anti-loosening and anti-vibration. Lock nuts by the type of classification are embedded in the polyester ring, with the neck closed edge, plus metal material anti-loosening device. They all belong to reasonable torque type lock nuts. The principle is that the embossed teeth are pressed into the pre-set hole of the sheet metal, and the general diameter of the square pre-set hole is slightly smaller than that of the compression rivet nut. Using the nut is connected with the locking mechanism, when tightening the nut, the locking mechanism locks the ruler body, and the ruler frame cannot move freely to achieve the purpose of locking; when loosening the nut, the locking mechanism disengages the ruler body, and the ruler frame moves along the ruler body. The common locking nuts are stainless steel locking nut, nylon locking nut, free flowing locking nut and spring clip locking nut.
3. Using double nuts to prevent loosening
Use a left-hand nut and a right-hand nut with tightening anti-loosening, two nuts in the tightening, the axial force between the nuts to increase the friction between the nut teeth and the bolt teeth, and then prevent the nut automatically loosened.
The above is to give you a brief introduction to the three tips to prevent the screws from loosening, I hope it will be helpful to you.
