Four major quality characteristics of wave springs

Our company has many years of experience in research and development, combined with customer needs and feedback information, and references relevant standards at home and abroad, summed up four major quality characteristics of wave spring: reliability, applicability, durability, environmental adaptability.

1. Reliability

In terms of reliability, we mainly improve the tensile strength of materials

Because the working height of wave springs under the same load is reduced by more than 50% compared to ordinary cylindrical compression springs, in order to meet product usage requirements and ensure product reliability, it is necessary to increase the tensile strength of the material. Based on theoretical design calculations and product big data, we have developed material tensile strength standards for different products. appropriately improve the product dimensional accuracy indicators and reduce the load tolerance indicators. At the same time, in order to facilitate customer design selection, we add a new elastic coefficient indicator, which is conducive to accelerating the pace of replacing imported wave springs with domestic ones, solving the current situation of imported parts blocking the neck and increasing the market share of domestic wave springs. production and use.

1. Durability

In terms of durability, the hardness index has been improved, and the measurement method and limit value for the fatigue life of wave springs have also been clarified, as wave springs are most prone to fatigue damage during long-term use.

The basis for determining the fatigue life indicator generally comes from the chapter on fatigue strength of springs in the spring manual, with the Goodman stress limit diagram represented by minimum and maximum stresses.

1. Environmental adaptability

In terms of environmental adaptability, in order to ensure the normal operation of the wave spring under certain environmental temperature differences, and in combination with the actual usage conditions of customers, a new temperature shock indicator has been added.
