By: Lee Spring A Belleville Washer is a cupped spring washer or conical washer, with a slight conical shape. It provides an axial force when deformed. This conical configuration enables the Belleville Washer to support high loads with relatively small deflections and solid heights, compared to helical springs. Belleville Washers are often used to solve vibration, thermal expansion and relaxation and bolt creep problems. Manufactured from 300 Series Stainless Steel, Lee Spring Belleville Washers offer good corrosion resistance for most applications. Additionally, Lee Spring Washers are passivated in accordance with specification ASTM A967 (supercedes QQ-P-35) to remove contaminants and further improve resistance to corrosion. 300 Series Stainless Steel is slightly magnetic and is recommended for any applications where the temperature is below 500° F (260° C). Belleville Washer stacking By stacking Belleville Washers in various configurations, additional load flexibility can be achieved. Belleville Washers can be used in four different ways: Single: One washer Parallel: All washers stacked the same way Series: All washers stacked opposite each other Series-Parallel: A single Belleville Spring Washer has a specific load for a given deflection. Two washers stacked in parallel will yield double the load of a single washer for the same deflection; three washers will yield triple the load; four washers will yield four times the load, etc. Alternatively, two washers stacked in series will yield double the deflection of a single washer for the same load; three washers will yield triple the deflection; four washers will yield four times the deflection, etc. Various series-parallel combinations therefore can provide a wide variety of combined results of load versus deflection for the stack. Consequently, depending upon the application, the designer can: • Stack in "parallel" to increase load • Stack in "series" to increase deflection • Adjust the load and deflection of a washer stack by adding or removing individual washers and/or the sequence in which they are used, whether in series or parallel Belleville Washers from Lee Spring Belleville Washers are available from Lee Spring for applications where a compression spring requires a high load in a small space.
