Abstract
A wave spring (10) is formed in which linear relation is retained between a load (P) and a deflection (S). Thereby, the degree of freedom of design of springs is enhanced. In forming a spring structure by coiling a spring material having flat cross section, a clothoid curve is selectively used as a shape-determining factor for the spring structure.
Claims2
A wave spring comprising a plurality of circumferential spring elements each of which comprises a wave shape having ridge and root sections;
- wherein said ridge and root sections of adjacent vertical spring elements are positioned opposite each other;
- and wherein said spring elements comprise continuously formed wave portions of substantially flat cross section having said ridge and root sections;
- said ridge and root sections having the shape of a section of a clothoid curve;
- and
- wherein the relation between a load imposed on said wave spring and a deflection produced in said wave spring by the imposition of said load is substantially linear.
A wave spring comprising a plurality of wave shaped spring elements each having a portion in the form of a clothoid curve and a portion in flat developed form, wherein said flat portions are tangentially connected to a terminal end of said clothoid curve portions and wherein said flat portions of said spring elements are substantially parallel to each other.
