Design of cylindrical helical springs
WebRecommended practice is to specify the number of active coils rather than pitch. C Spring Index = D/d = ratio of mean coil diameter (D) to wire diameter (d). The preferred index range is 4 to 12. Helical springs with high indexes tangle and may require special packaging. Springs with indexes lower than 4 are difficult to form. WebThe helical spring is made from a wire, usually of circular cross-section, that is bent in the form of a helix. There are two basic types of helical springs: compression spring and tension spring. In helical compression spring, …
