Disc Spring |
|
Conical shaped disc springs were first conceived in the mid-1800's and the invention was subsequently called a Belleville Washer after its inventor Julian Belleville, who received a patent for the product in 1867.
Developments such as the internal combustion engine, turbine and jet systems, nuclear power, oil and gas exploration etc. have progressively advanced this simple spring device to the sophisticated energy storage system that it is today |
Disc springs are conical shaped washers, designed to be loaded in the axial direction F only. They can be statically loaded, either continuously or intermittently, or cyclically deflected i.e. dynamically loaded.
Infinitely variable spring characteristics can be achieved by the arrangement of disc springs into stacked columns. |

INTRODUCTION
Disc Springs offer a well developed solution to many engineering problems, which are loaded in the axial direction. Disc Springs are conically formed measured by angle in Discs through a equal combination of high force in a small space. Computerized design programmed to assist our customers for their specified applications.Disc Springs can be used as single disc or arranged in stacks. A spring stack can consist of either parallel spring and single spring sets. Disc Springs are obtainable with or without contact flats. Disc Springs and most Belleville Washers are manufactured to DIN 2093 AND din 6796. Disc Springs are manufactured material are 17/7PH, 304, 50CrV4 inconel as per customer requirement and our Disc Springs are AUSTEMPERED. This systematic procedure of heat treatment is especially effective for springs as it gives the maximum tearness and therefore considerable hard wearing durable.

DISC SPRING STACK COMPARED TO HELICAL SPRING
The same load is achieved at essential reduction in space. Disc stacks may be designed for a high loads where coil springs are not practicable at all.

STACK LENGTH
When stacking Disc Springs determined attempt should be made to keep the stacks as short as possible. This effect usually can be disregard for a normal spring stack but not for long stacks. Friction and other power make a stack more uneven. If it is longer the stack can be stabilized by dividing it with guide washers, which as a rule of thumb should have a thickness of at least one and a half times the guide diameter. It bend more on the side of the loading. |

Advantages of Disc Springs |
| 1) |
Long Service Life. |
| 2) |
Space Saving. |
| 3) |
No Deformation or extreme tiredness under normal loads. |
| 4) |
Low Maintenance cost. |
| 5) |
High Energy Storage Capacity. |
| 6) |
Capable use of space and high spring force with small deflections. |
| 7) |
Adaptable to stacking in numerous configurations. |
| 8) |
Largely Self-damping giving good shock absorption and energy dissipating. |
| 9) |
Stock keeping is minimized as the individual spring sizes can be combined universally. |
