Butterfly spring washer (disc spring)
Disc spring (spring) is a spring washer type conical section with a metal sheet or the forging blank. The disc spring has the characteristics of small size, large load, convenient assembly and convenient use, and the disc spring has the advantages of centralized load transmission. The different curves can be obtained by the combination of single plate and disc spring, multi disc spring combination and the mixing and combination of the disc spring.
Dish spring is characterized by:
1 stiffness, strong damping capacity, can be small deformation to bear large loads, suitable for small space requirements of the occasion.
2 deformation stiffness characteristics can be obtained by appropriate choice of the ratio of the amount of deformation and thickness of the plate spring, the different characteristics of the curve. The characteristic curve can be linearly increasing, decreasing shape, shape or their combination, this spring with nonlinear characteristics very widespread.
3 with the same disc spring using different combinations, can make the spring characteristics of a wide range of changes. Can adopt the combination of the combination of the composite, the composite can also be used as a combination of different thickness, the number of films, etc.. When folded, with the same number of spring deformation, the more the bigger loads. When the time, for the same load, the more the number of spring is the greater the deformation.
The application of disc spring in mechanical products is wider and wider, and in a large range, the disc spring is replacing the cylindrical spiral spring. Commonly used in heavy machinery (such as press) and artillery, aircraft and other weapons, as a strong buffering and damping spring, used for automobile and tractor spring clutch and safety valve or pressure relief valve in the mobile device, and used as a storage device, converting mechanical energy stored to deformation energy.
