Graduated-Load Spring Washer System for Screws and Threaded Fasteners.
Abstract
The present invention relates to spring washers and particularly to a graduated-load spring washer having a tailored configuration in screw or threaded fastener systems that will maintain large preloading and screw-locking force before, during and after joint thickness change due to material stress relaxation, creep or wear. The graduated-load spring washer system of the present invention can be tailored to provide a precise clamping force due to its similarity to a single turn coil spring. The present device has the capability to provide for small loads as a single turn coil spring or large loads due to its deflection similar to a Belleville washer. Patent application. (jes)
