The Gasket Has A Good Locking Effect
Oct 30, 2017

Although the gasket is humble, but it is a vital role, many types of gaskets, different sizes, different materials, play a different role.

We will still see in life, its role there are two, Seals the first is to increase the sealing, the second is used to adjust the gap between the parts.

The washer consists of two gaskets, with a radially convex surface on the outside and a bevel surface on the inside.

The working principle of the washer is very simple: it is when the assembly, Seals the inner side of the oblique tooth between the opposite, the outer radial convex surface and the two ends of the contact surface into the bite state, when the connector by vibration, and the bolt loosening trend, The inner side of the washer is relatively dislocated, resulting in lifting tension, so as to achieve 100% locking effect. The washer can be applied to all strong vibrating environments.

Features: High safety performance; Seals to prevent loosening due to vibration and power load; easy installation and removal; locking effect is not affected by lubrication; regardless of preload level has a good locking effect; can control the level of preload ; Has the same temperature characteristics as standard bolts / nuts; reusable and so on.

Gaskets are widely used in the bearing and non-bearing structures of general mechanical products. They are characterized by low cost and easy installation. They are suitable for frequent parts of assembly and disassembly. Washers are easy to optimize the selection of automation, but the gasket of the anti-loose ability is very low! Especially in Europe and the United States require high reliability products in the adoption rate is very low, Seals especially the important bearing structure of the connection has long been abandoned. Our country has some applications in the military sector, but has improved to stainless steel. Steel washers have long been banned in CASC! Also said to be very unsafe, the reason there are two 1 is "rose circle" 2 is hydrogen embrittlement.

Washers in the screw industry, often called the elastic pad. Its material is made of stainless steel and carbon steel, carbon steel is iron. Commonly used gasket specifications are M3, M4, M5, M6, M8, M10.M12, M14, M16. Seals These specifications are more commonly used. Washer national standard GB / T 94.1-87, the standard specification of the standard size of 2 - 48mm gasket. Reference standard GB94.4-85 "Elastic washer technical condition Washer"
