Advantages and features of butterfly washers Classification Industry Solutions

Disc spring washers and disc washers are tapered elastic fasteners, usually made of spring steel, used to carry axial forces. Unlike wave springs, disc springs and disc washers can generate more force in a relatively small area. Both are characterized by high life, low deflection, and high load-carrying capacity. Some people think that DIN 6769 is the German standard disc spring washer, but this statement is wrong; DIN 6769 is essentially a kind of anti-loosening washer, all known as bolts with conical elastic washers, and DIN 2093 for the disc spring. That is to say that the two are a spring and a washer; although the washer has elasticity, the actual use of the environment and working conditions requires a big difference. The disc washer is pressed flat and is 70-90% of the bolt load. It is suitable for 8.8-12.9 grade high-strength bolts and is the perfect choice for bolt connection.

The advantages and characteristics of disc washers industry solutions

Disc washers have a high axial load, high life, and high load drop (caused by temperature difference) compensation, effectively reducing the negative impact of dynamic load, anti-loosening locking, high elasticity, load concentration uniformity, security, and other advantages. Because disc spring washers have anti-loosening, anti-vibration effects, low manufacturing costs, easy to install, and other characteristics, more and more fields use disc spring washers, including automotive, electric power, construction, machine tools, aerospace, defense systems, medical equipment, and other industries.

The classification of disc washer industry solutions

1. DIN 6796 (HDS series) is designed for bolted and screwed joints of the anti-loosening washers. After the bolts and screws connection, to prevent the relaxation of tension, wear, and tear of wearing parts, creep, thermal expansion, contraction, and sealing of the compression played a compensatory role. HDS series increase the elasticity of the screws by several times; it can effectively replace ordinary spring washers, but not lock washers or flat washers combination.

2. High-torque disc spring washers have a temperature range of -200 ~ 300 ℃. High-torque disc washers have more muscular elastic tension and are used in the anti-loosening fastening joint equipment of high-speed railroad cars with intense power loads. High-torque disc washers are widely used; they are a kind of high-torque anti-loosening function washers used with bolts, suitable for high-strength rigid connection design.

3. Ultra-high torque disc spring washers temperature range of -200 ℃ ~ 600 ℃. Ultra-high torsion disc springs made of high-temperature resistant materials can play an influential compensating role in the temperature range so that the bolt preload on the gasket is maintained in a particular range, thus preventing bolt fatigue and gasket failure, but also significantly improve the maintenance cycle of the equipment. High-torque disc springs can effectively absorb mechanical vibration to avoid the loosening bolts caused by mechanical vibration and ensure the seal is durable and reliable.

According to the torque range of disc spring washers for classification, but also according to the role of different, divided into VS, S series of disc spring lock washers, bearing preload disc washers, flange washers, etc., if you want to pick the proper disc spring washers, you can contact Juxin Fasteners, we have professional designers for you to determine the specific conditions of the use of disc spring washers.
