1. Ring springs

1.1 Role and employment

Ring or ring springs are only used in compression. Their internal friction absorbs so much energy that they are only used when the work they return is undesirable. This is the case with shock absorbers. What's more, the return shock is reduced by as much as 70%.

1.2 Constitution

These springs consist of unslotted rings of two shapes, in which the outer surfaces of the inner ring a and the inner surfaces of the outer ring b are conical. When loaded along their axis, these...
