As a Rail Clamp Plate Manufacturer, share with you. As a common connection part, bolts are commonly used in machinery, automobiles, trains and building structures. Choose suitable bolt types according to different requirements. The bolt connection is also the most basic structural form of the fastener connection. The anti-loosening effect is a part that cannot be ignored. The following China Standard Parts Network analyzes how to make the gasket play a better value in the fastener bolt connection. It can be seen that the anti-loosening effect in many bolt connections is improved by using washers.

We all know that the bolts will loosen due to vibration, high and low load changes, and long-term working conditions during the use of the equipment. In many cases, in order to prevent the bolts from loosening, we will add washers to the bolts for more tightening.

In daily use, in order to prevent bolts from loosening, bolt anti-loose measures can be roughly divided into the following two aspects: physical device anti-loose and process method anti-loose.

Anti-loosening measures of physical devices:

(1) Anti-loose device with additional friction

(2) Mechanical anti-loosening device

(3) Bonding and anti-loose device

Process method anti-loose measures:

(1) Anti-loosening of fixed torque tools

(2) Training and training anti-loosening

(3) Quality control of parts and components

This time, we analyze the anti-loose device with additional friction of the physical device anti-loose measures:

The anti-loosening device with additional friction has three main structures: double nut tightening structure, spring washer tightening structure and self-locking nut tightening structure. Double nut tightening structure: first tighten the lower nut and then tighten the upper nut. After the two nuts are tightened, the upper and lower nuts and the bolt thread contact surfaces are opposite, so that the screw threads are always subjected to additional pressure and friction, and the working load When there is a change, the friction still exists. The structure is simple, and it is suitable for the connection of stable, low-speed and heavy-load fixed devices.

Among them, the spring washer tightening structure: the spring washer is widely used in the assembly site because of its simple structure, convenient use and low cost, and is generally used in conjunction with bolts or nuts. After the bolts or nuts are tightened, the elastic reaction force produced by the flattening of the washers makes the screw threads tight. At the same time, the tip of the oblique mouth of the washer resists the bearing surface of the bolt or nut and the connected part to prevent loosening.

But in the bolt connection, is it really effective to reduce the loosening of bolts when using washers?

During the operation, whether to use a washer or what washer should be used depends on the actual situation.
