Wave Washer Design Guide

Another advantage is that one can increase the number of turns of the spring design in order to decrease the deflection per turn when the wave spring is compressed.

Wave washer design guide. Everything rf lets you search for waveguide products check it out. Wave washers also referred to as wave springs are wavy metal washers designed to provide a compensating spring force or absorb shock when under load. By reducing spring operating height wave springs also produce a decrease in the spring cavity. They are formed using bespoke tooling in an irregular shape so that when loaded they act like a spring deflecting and providing a pre load between two surfaces.

Its irregular shape helps provide pressure to secure the fit and prevent loosening of the bolt or screw. Phase velocity and group velocity. The solid height of the wave spring so that with the same amount of turns one can visibly reduce the work height without compromising the load or spring deflection. Our engineers have designed thousands of custom springs across nearly every industry.

Simple wave or spring washers as they are commonly known are traditionally manufactured by die stamping from annealed sheet metal and then hardened by an austempering process. The modeling on wave spring washers is presented in section ii. Send us your requirements using one of our helpful engineering tools. Waveguide is a huge topic for anyone studying microwave engineering entire books have been written on the topic.

It is used to provide flexibility cushioning and noise reduction and may help for variations in tolerance. Spring will take a set if subjected to a higher stress. The remainder of the paper is organized as follows. A wave washer also known as a spring washer is a fastener that has a single double triple or multiple waved shaped body.

Physical design constraints including bore geometry shaft id od and so on the application load the working height at which the design applies load and the spring material that will best withstand the application environment. Wave spring design general considerations if a spring is designed for static application make sure that the stress at working height is less than 100. Looking for a custom application specific wave spring. Four critical factors dictate the most suitable wave spring for a given application.

Rf cafe has some good stuff on waveguide check it out. The design of a wave spring washer is thus systemized as optimizing its five control parameters. Smalley wave springs flat wire compression springs offer the unique advantage of space savings when used to replace coil springs. Group delay in waveguide.

More after the jump. Smalley engineers are available for free design consultations. If a spring is designed for dynamic application make sure that the stress at working height is less than 80.
