Disc Spring Stack Calculator

A reasonable allowance is 2 3 of the force for each sliding surface a greater force for loading and a lesser force for unloading. Disc springs are often stacked to enhance performance characteristics. 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.

Disc spring stack calculator.

Contact our technicians to corroborate the calculations. 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. Tensile stress σ 10 6 pa. Spring deflection f 10 3 m.

Stacking disc springs in series and parallel. By stacking them in parallel load bearing characteristics are enhanced. Was 13345 n cell m5 but in stack spring force we got 24981 n cell k57. I need to ask you one doubt in calculation.

Disc springs stacking consideration needs to be given to the friction between the parallel disc surfaces. Spring stiffness k df df f f 10 3 n m. Calculator for disc compression springs. First of all thank you very much for this useful calculation to understand the concept of disc spring design.

The calculator helps to set the stacks of disc springs. The combination of both series and parallel stacking see no. To calculate the spring response of a stack of disc belleville springs calculation description this sheet calculates the spring response for a disc spring stack with no contact flats using equations from disc spring manufacturer s handbook the equations used in this calculation give approximate values for the spring force and stress. You have two identical springs with a spring rate of 30 lbf in pounds of force per inch.

Spring inner diameter d0 2 r0 10 3 m. Tables should be consulted for measured results the. Modulus of elasticity e 10 9 pa. 4 above illustration is a means of multiplying both force and deflection the guidelines applicable to this type of arrangement are basically those already outlined but it cannot be over emphasised that it is important at the disc spring selection stage to minimise the number of.

The slight or aggressive conical shape gives the washer a spring characteristic and action. The formula for this calculation is also provided below. This calculator aids in designing preferred stack arrangements for your design. The resulting keq is the new rate for the two springs in series.

Spring force f n. If you have additional questions or require assistance please. Please follow the instructions below for using mubea disc spring s calculator tool. Spring outer diameter d 2 r 10 3 m.

A belleville spring or washer is formed into a conical or cone shaped geometry. When stacked in series greater deflection or travel is achieved. To calculate the rate these two provide together simply multiply the rate by 1 2 0 5. Our target desired load at 80 defl.

Discs in parallel should be well lubricated and it is suggested that the number of discs in a parallel set be limited to a maximum of 4 to reduce the.
