Od represents the washer.
Belleville washer spring rate.
N i the number of washers in the i th group.
Belleville washers engineering data belleville washer stacking example.
Because belleville washers can bear a much larger load relative to its deflection rate than a coiled spring they are ideal for cushioning heavy loads with short motion.
This notation is needed for load calculations if n of springs in a stack then.
Spring thickness δ 10 3 m.
A belleville spring or washer is formed into a conical or cone shaped geometry.
A belleville washer or disc spring is a conical shaped spring with an open center.
Spring outer diameter d 2 r 10 3 m.
Performance considerations a similar device is a wave washer.
1 spring is considered to be 1 in parallel 1 in series.
These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws.
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.
Tensile stress σ 10 6 pa.
Spring force f n.
Spring stiffness k df df f f 10 3 n m.
G the number of groups.
So a 2 3 1 2 stack or since addition is commutative a 3 2 2 1 stack gives a spring constant of 3 7 that of a single washer.
T represents the washer material thickness as well as the washer solid flat height.
It is shaped much like a washer and is typically smaller than a coiled spring.
Modulus of elasticity e 10 9 pa.
This is a minimum measurement and reflects the bolt size that the washer will accommodate.
Spring deflection f 10 3 m.
Belleville spring lock washers also known as conical washers these have a slightly cupped shape that gives them spring like flexibility to grip tighter than split and tooth lock washers.
K the spring constant of one washer.
Belleville spring washer coned disc spring and conical spring washer are all names for a type of spring that is a conically shaped disc that deflects flattens at a given rate.
Conical spring washers have a high spring rate resolve thermal expansion and can produce extremely high loads in a small area.
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.
The slight or aggressive conical shape gives the washer a spring characteristic and action.
888 426 6655 id represents the washer inside diameter.
A belleville washer also known as a coned disc spring conical spring washer disc spring belleville spring or cupped spring washer is a conical shell which can be loaded along its axis either statically or dynamically.
