The required various load/deflection characteristics of Belleville disc springs can be obtained from the various stacking combinations. The stack combination methods and load&deflection relation as the table below. Disc spring can be used in a single piece, as well in multi pieces with different combinations. It is usual to use disc spring stacks with various combinations to meet your specified applications.

Disc Springs - HEGONG SPRING

Disc Springs are conically washers and have a rectangular cross-section, which is loaded in the axial direction. It has a small volume and large energy storage compared to traditional helical springs and can be used as single disc spring or in the stack (stack in parallel, in series or in parallel & series combination).

Your Ultimate Guide to Belleville Washers

Belleville washers serve the purpose of preventing fasteners from loosening due to vibration, absorbing shock, and maintaining joint integrity. These conical washers find widespread use across various industries including automotive, energy, distribution, chemical, pump and valve manufacturing, industrial automation, utility transmission, and more. Specifically designed for high-temperature environments and highly corrosive settings, American Belleville washers excel in ensuring top-notch quality. They are engineered to counteract relaxation effects, address thermal expansion concerns, and prevent bolt yield.

How Do You Stack Disc Springs?

Andy Lu07 May, 2024Business

Single disc springs are assembled ?opposed to each other? to form a spring column. This ?in series? formation (no.3 in above illustration) is a means of multiplying the deflection of a single disc spring, the force element remains as that for a single spring. E.G. A disc spring that requires a force of 5000N to deflect 1mm, when assembled to form a column of 10 disc springs in series, will require a force of 5000N to deflect 10mm.

Unlocking the Purpose of Stacking Belleville Disc Springs

In the realm of mechanical engineering, the innovation and versatility of Belleville disc springs have garnered substantial attention. These ingenious components, also known as conical spring washers, have a wide array of applications that cater to industries ranging from aerospace to automotive. One intriguing facet of these springs is their ability to be stacked ? a technique that amplifies their utility and flexibility. In this comprehensive exploration, we delve into the purpose behind stacking Belleville disc springs, uncovering the advantages, applications, and considerations that underscore this technique's significance in modern engineering.

Serrated Safety Washers

Andy Lu05 May, 2023Business

Serrated Safety Washer is a kind of Belleville Disc Spring with trapezoid cross section and serrations on both sides. Serrated Safety Washers are connected with bolt or screw, it can prevent bolt relaxation after vibration by increasing the friction resistance. Serrated safety washers are available in two different types: S type is suitable for normal duty, available for screw sizes: M1.6 to M36. VS type is thicker and therefore achieves higher pretensioning loads, be used with high strength bolts, available for screw sizes: M5 to M36.
