Disc spring application
A wide range of disc springs are replaced by a cylindrical coil spring. Commonly used in heavy machinery, such as presses, and artillery, aircraft and other weapons, as a powerful buffer and damping spring, used as a car with tractor clutch and a safety valve compression spring, as well as energy storage devices for amusement devices. Disadvantages: load deviation is difficult to guarantee. Disc spring, depending on the section shape can be divided into three categories: ordinary disc spring (the cross-sectional shape of a rectangle), with radial grooves of the disc spring, trapezoidal cross-section disc spring. Ordinary disc spring is divided into two types of support surface and support surface; with radial grooves of the disc spring is on the basis of the ordinary disc springs along the radial direction out of a number of evenly spaced slots, the slots can be bore out round the direction of out, you can also open to the internal control direction by the cylindrical; disc spring of the trapezoidal cross section can be divided into the inner edge thickness is greater than the foreign aid thickness and edge thickness is less than the outer thickness of the two categories. The single disc spring deflection and load value often can not meet the requirements, then you can group, composed of the disc spring assembly (column). A typical combination is: superimposed combination of the disc spring complex combination disc spring, disc spring, and other combinations. Compared with the cylindrical coil spring, disc spring has the following characteristics: a load-deformation characteristic curves showed a nonlinear relationship. , Disc springs into a thin shape, easy to form a combination, can implement the building-block assembly and replacement, and thus to the maintenance convenience. With a radial slot disc spring with zero stiffness characteristic. This feature can be applied to the spring force to maintain the basic stability of the occasion in a deformation range requirements. Disc spring vibration absorption performance of not less than the cylindrical coil spring, due to friction between the plate reed and has a larger damping when using composite combination to dissipate the impact energy.
