Abstract
The invention relates to a variable-diameter helical compression spring which aims to solve the technical problem of non ideal effect in nonlinear application occasions of a stiffness helical compression spring of the prior art. The invention is formed by a steel wire being spirally winded up, and the diameter of the steel wire is changed along the axial direction of the steel wire. Furthermore, the steel wire can take the shape of a cone, or the steel wire consists of at least two sections of cylinders being connected with each other in the axial direction, and the diameter of any one section of cylinders is larger than or smaller than that of any one adjacently connected cylinder. Because the diameter of the steel wire forming the spring by winding is changed along the axial direction of the steel wire, the spring can obtain a variable stiffness characteristic curve. The invention has simple structure.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to the elastic mechanical element, particularly a kind of diameter variable 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 purpose of this invention is to provide a kind of diameter variable spiral compression spring, described this diameter variable spiral compression spring will solve prior art moderate stiffness spiral compression spring unfavorable technical problem of effect in nonlinear application.
This diameter variable spiral compression spring of the present invention by a steel wire with helical coil around constituting, it is characterized in that: described gauge of wire is along the axial change of steel wire.
Further, described steel wire is coniform.
Perhaps, to connecting and composing, any one section described cylindrical diameter all is greater than or less than the cylindrical body of any one adjacent connection to described steel wire by at least two sections cylinder axis.
Working principle of the present invention is: constitute the axial change of the gauge of wire of spring along steel wire owing to reel, so spring can obtain to become the characteristic curve of rigidity.
The present invention and prior art contrast, and its effect is actively with tangible.The steel wire coil that the present invention changes diameter vertically can obtain to become the characteristic curve of rigidity around constituting spring.Simple in structure.
Description of drawings:
Fig. 1 is the structural representation of the steel wire in the diameter variable spiral compression spring of the present invention.
Fig. 2 is the structural representation of the embodiment of steel wire in the diameter variable spiral compression spring of the present invention.
Embodiment:
As shown in Figure 1, diameter variable spiral compression spring of the present invention by a steel wire 1 with helical coil around constituting, it is characterized in that: the diameter of described steel wire 1 is along the axial change of steel wire 1.
Further, described steel wire 1 is coniform.
As shown in Figure 2, described steel wire 1 is is axially connected and composed by at least two sections cylindrical bodys 2, and the diameter of any one section described cylindrical body 2 all is greater than or less than the cylindrical body 2 of any one adjacent connection.
Working principle of the present invention is: the diameter of the steel wire 1 that constitutes spring owing to reeling is along the axial change of steel wire 1, so spring can obtain to become the characteristic curve of rigidity.
