Using the conservation of energy and balance conditions, it is shown that the shape of the pulley on the spring side of a spring balancer takes on a special spiral shape for the case of a fixed pulley on the weight side. Conversely, it is shown that the shape of the pulley on the weight side takes on an involute shape for a fixed pulley on the spring side. It is also shown that design work is simplified by expressing the spring design equation as a maximum potential energy function.
