Abstract
The invention relates to a multistage variable rigidity structure for a helical compression spring, which is formed by three equal-rigidity helical compression springs with degressive diameters; wherein the three equal-rigidity helical compression springs are sleeved together in the axial direction, the three equal-rigidity helical compression springs have respectively different heights, and the bottom ends of the three equal-rigidity helical compression springs are firmly connected with the same base. The sequence of the pressure acting on the three equal-rigidity helical compression springs is different, therefore the characteristic curve of the variable rigidity can be gained. The three equal-rigidity helical compression springs can be combined and arranged in accordance with the heights in order to gain the different characteristic curve of the variable rigidity.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to the multilevel stiffness changing structure of elastic mechanical element, particularly a kind of spiral compression spring.
Background technique:
In the prior art, manufacturings such as machinery, electrical equipment, hydraulic pressure such as generally adopt as elastic element at the stiffness helix pressure spring.Characteristic curve Deng the stiffness helix pressure spring is a straight line, and therefore effect is undesirable in some nonlinear applications.
Summary of the invention:
The multilevel stiffness changing structure that the purpose of this invention is to provide a kind of spiral compression spring, the multilevel stiffness changing structure of described this spiral compression spring will solve prior art moderate stiffness spiral compression spring unfavorable technical problem of effect in nonlinear application.
The multilevel stiffness changing structure of this spiral compression spring of the present invention is by one first pressure spring such as stiffness helix such as grade, one second stiffness helix pressure spring such as grade and a C grade stiffness helix pressure spring constitute, wherein, the diameter of first pressure spring such as stiffness helix such as grade is greater than the diameter of second pressure spring such as stiffness helix such as grade, the diameter of second pressure spring such as stiffness helix such as grade is greater than the diameter of C grade stiffness helix pressure spring, the bottom of first pressure spring such as stiffness helix such as grade is fixedly connected with a base, second pressure spring such as stiffness helix such as grade is arranged in first pressure spring such as stiffness helix such as grade, C grade stiffness helix pressure spring is arranged in second pressure spring such as stiffness helix such as grade, all fixedly connected with described base in the bottom of second pressure spring such as stiffness helix such as grade and C grade stiffness helix pressure spring, the height of first pressure spring such as stiffness helix such as grade is greater than or less than the height of second pressure spring such as stiffness helix such as grade, the height of second pressure spring such as stiffness helix such as grade is greater than or less than the height of C grade stiffness helix pressure spring, and the height of first pressure spring such as stiffness helix such as grade is greater than or less than the height of C grade stiffness helix pressure spring.
Further, the screw axis of a stiffness helix pressure spring such as described first pressure spring such as stiffness helix such as grade, second and a C grade stiffness helix pressure spring overlaps.
Working principle of the present invention is: because the height of three pressure springs such as stiffness helix such as grade is different, pressure acts on three order differences that wait on the stiffness helix pressure spring, therefore can obtain to become the characteristic curve of rigidity.And stiffness helix pressure springs such as three highly can be carried out assembled arrangement according to it, obtain different change load-deflection curves.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention waits stiffness helix pressure spring fit in the axial direction with three different heights, can obtain to become the characteristic curve of rigidity.And stiffness helix pressure springs such as three highly can be carried out assembled arrangement according to it, obtain different change load-deflection curves.Simple in structure.
