When the design of a machine means that space is tight, Lee Spring is pointing out that its REDUX wave springs offer high functionality in space-critical applications. They are designed to replace conventional round wire compression springs and also to provide tight load deflection in a very small area - which enhances efficiency, reduces operational costs and permits smaller assemblies according to the company.
Wave spring applications are many but include connectors, pumps, clutches, seals, medical equipment and valves where uniform force distribution and/or uniform rotational pressure is required over 360 ° in restricted spaces. Lee Spring states that REDUX wave springs offer a way of performing a spring function where in places where alternative springs might struggle to work effectively. Typically, a REDUX wave spring will occupy just 30-50 per cent of the compressed height space of a conventional round wire spring, yet offer more deflection with the same load specifications. This not only helps to save space in an application: it also reduces the production costs, as fewer materials are required.
Wave springs come in a wave top to wave top format manufactured from a single filament of Type 17-7 Stainless Steel flat wire formed in continuous precise coils with uniform diameters and waves. REDUX wave springs are offered in diameters from .236" (6.00mm) to 1.772" (45.00mm) to meet load requirements from 2lbs (0.9kg) to 90lbs (40.8kg). Ex-stock specifications are suitable for static and slightly dynamic load applications where they provide a degree of anti-vibration operation or maintain constant pressure in a mechanism with limited height constraints.
More dynamic applications require special solutions because the additional stress put on the waves is likely to cause abrasion at the point of contact. In cases like these Lee Spring welcomes calls or emails to discuss potential options and has an experienced team available during standard business hours.
