5/16 Flat Spring Washers

About 5/16 Flat Spring Washers

Spring washers are specifically designed to provide a compensating spring force and sustain a load or absorb a shock. Many design variations have evolved to best serve one or the other of these two basic functions or to optimize both functions in a single part within specific I.D./O.D. limits. Two principle factors are at work that continually increase the requirement for spring washers:

The continuing effort to down-size many end products, relative to both weight and cost, creates a need for small, multi-functioning assembly components,such as washers that support a load,span a hole,or both,while providing a compensating spring force.

Automated assembly requires some "play" or tolerance in the "fit" of components. Spring tension is needed to compensate for these tolerances. Recognizing these two broad areas of influence,it can be stated that the more common applications for spring washers are:

- To take up "play" in assemblies due to cumulative commercial tolerances.

- To compensate for small dimensional changes in assembled components.

- To eliminate end play or rattles.

- To maintain fastener tension or "tightness".

- To compensate for expansion and contraction or cold flow of material.

- To absorb intermittent shock loads and function as working springs capable of providing controlled reaction under dynamic loads.

A. Single Wave Washers

These washers are designed for applications involving low loads and requiring high deflection. The Load/Deflection (L/D)curve for this type of washer is virtually linear. Applications include the take up of large tolerance variations,eliminating end play in electric motors,minimizing rattles and cushioning light loads.

- Apply greater bolt tension per unit of applied torque.

- Provide hardened bearing surfaces to create more uniform torque control.

- Provide more uniform load distribution through controlled radii (section) cutoff.

- Provide protection against looseness resulting from vibration and corrosion.

- Optimum locking device for use in applications with hardened faying or bearing surfaces.
