Belleville Disc Springs Calculation

Belleville springs has been trading in the spring industry for over 40 years and is a leading uk manufacturer and stockist of disc springs and belleville washers who export their products worldwide.

Belleville disc springs calculation. The same way up the resultant force for such a column is the force element of a single disc spring multiplied by the number of nested disc springs in the column whilst the deflection remains the same as for that applicable to a single disc spring. Disc springs are assembled nested inside each other i e. Florence ky 859 746 2155. Belleville washers disc springs disc springs are conical washers with elastic properties.

Mubea disc springs providing service worldwide. Belleville springs aka belleville washers spring washers or disk springs are wonderfully useful mechanical devices but with one minor drawback their properties are difficult to calculate until now. Stacking disc springs in parallel. The fatigue life is only calculated for shot peened disc springs made of 50crv4 or ck67 operating at t 20o c.

Belleville washers are typically used as springs where the spring action is used to apply a pre load or flexible quality to a bolted joint. Should the disc springs be subjected to a rarely alternating or static load the fatigue life calculation can be deleted from the data sheet by clicking the remove fatigue life tab on the right side of the screen. A belleville washer is a type of spring shaped like a washer it is the frusto conical shape that gives the washer its characteristic spring. A belleville spring or washer is formed into a conical or cone shaped geometry.

The calculator helps to set the stacks of disc springs however the information provided is theoretical and may sometimes be necessary to consider other factors of the application such as friction to correctly predict the behavior of the springs. A disc spring sometimes called a belleville washer after the inventor consists primarily of a convex disc supported at the outer periphery by one force and an opposing force on the center of the disc disc springs are used singly or in stacks to achieve a desired load and travel the advantage of a disc spring is that it generates high force in a very.

These springs are resistant to axial loads proportionally to the displacement produced in the piece.
