Cylindrical spiral
compression spring to crush as the load increases, when the spring material surface shear stress also increases gradually, until the material more than the elastic limit and the plastic deformation occurs, and near the core will gradually achieve the elastic limit of material, after unloading, due to the effect of material of outer plastic deformation can't fully recover, residual deformation.
this spring when the work stress of materials for the core increase, surface stress decreases, and the change of the stress can be bring into full play the potential of materials.
Normal limits of spring are generally considered in the design of spring deformation, will not exceed the limit of the spring stress.
The allowable shear stress of material is different, the spring by load category is different, have different spring allowable stress.
the concrete calculation according to the spring by the axial load, the calculation formula of the deformation and shear stress.
If less than the limit value, the spring can be pressed and, if is greater than the limit value, in order to limit value for the maximum amount of compression.
Beyond the limit spring will produce permanent deformation.
Dongguan Yongqiang spring hardware Co.,Ltd. undertakes bulk operations and specializes in undertaking corporate offers to cater the needs of different companies.
Always do our research, follow the rules and plans ahead for additional expenses. Expanding is the goal of Dongguan Yongqiang spring hardware Co.,Ltd.; expanding properly is the goal of the wise business.
But we do think that reckoning with supply chains of News is a really important step. Even super simple switches in material, or sourcing, or shipping, or worker benefits seems like good place to start.
