Packing more force into less space with Daemar wave springs

Wave springs have some advantages over disc springs.

Daemar’s unsurpassed selection of essential components for industry includes retaining products, like wave springs. Flat-wire wave springs have advantages over traditional spring designs, like coils and discs, in many applications. Although coil and disc springs suit many engineering tasks, single- and multi-turn wave springs are better in certain circumstances. Users should consider force considerations and the ability to provide consistent force when choosing springs.

Axial and radial space savings

Other key benefits of wave springs in many engineered systems and demanding environments include space savings, absence of torsional loads, better dimensional tolerances, and increased travel. Another example: wave springs provide consistent force over a broad range of deflections. They can make fine linear adjustments across the entire force range, offering deflection curves with a wider, flatter linear force region. This feature is useful in fishing reels, gear sets, slip clutches, flow and safety valves, and quick connectors.

Another advantage of Daemar wave springs is that they save space and need less machining. In static applications, wave springs usually need half the work height of equivalent coil springs. Just one multi-turn wave spring can replace multiple coil springs in a traditional seal design. Wave springs can save radial space too. Users can easily satisfy space constraints with wave springs in mechanical seals and downhole tools.

In addition, wave springs manage targeted loads in tiny spaces. Some applications are too small to make room for traditional coil springs, which can be bulky. Wave springs are useful in these cases for applying necessary pre-load in small spaces. This advantage works especially well for ultrasonic motors, which measure millimetres in length. A single-turn wave spring can maintain pressure against the stator, holding the rotor in place without screws or bolts.

Finally, wave springs can be used to pre-load bearings, reduce endplay, and minimize vibration. Applying a permanent thrust load to a bearing assembly is important for a secure, successful installation. The bearing pre-load process expands component lifespan by eliminating unnecessary clearances, boosting stiffness, and decreasing noise and vibration – ideal for diesel-engine water pumps and fluid power assemblies.
