Detailed description of the invention
This utility model embodiment will be described in further detail below.
Opening tensioner ring formula energy dissipation spring of the present utility model, its preferably detailed description of the invention is:
Including annulus in being arranged in single conical surface at two ends annulus and being arranged in the zero at middle part, one or several Double-conical-surfaces, in the single conical surface in adjacent single conical surface between annulus or adjacent, outside between annulus is provided with open type outer toroid between annulus with annulus in Double-conical-surface and in adjacent Double-conical-surface.
In described single conical surface, in annulus and Double-conical-surface, annulus is closed configuration, one and two conical surfaces are had respectively outside it, described open type outer toroid has an otch at hoop, inside it, two ends are respectively arranged with a conical surface, and in described single conical surface, in annulus and Double-conical-surface, the conical surface of annulus matches with the described open type outer toroid conical surface.
The tapering of the described conical surface is 12 degree～30 degree.
Described open circular is single layer structure or the fabricated structure of multilamellar intussusception.
In the open circular of described fabricated structure, comprising internal layer split ring and outer layer split ring, there are two conical surfaces at the two ends, inner side of internal layer split ring, and the external diameter of internal layer split ring is equal with the internal diameter of outer layer split ring, is being formed radially cooperation.
In described single conical surface, in annulus, Double-conical-surface, annulus, the material of open type outer toroid use spring steel or high-strength aluminum alloy.
In described single conical surface in annulus and Double-conical-surface the radial rigidity of annulus more than the radial rigidity of described open type outer toroid.
Opening tensioner ring formula energy dissipation spring of the present utility model, for existing ring spring deficiency in cushion stroke, by the improvement in structure, employing conventional metal material, simple in construction, cushion stroke are big and cheap, have versatility.
This utility model retains the basic structure of ring spring in prior art, comprises inside and outside annulus, and is assembled by cone match.But being in place of Qu Bie, outer toroid of the present utility model is hatch frame, it it is i.e. one little breach of incision on closed circle；And interior annulus remains in that as closed configuration.Inside and outside annulus can use the conventional metal material such as spring steel or high-strength aluminum alloy.With the outer toroid of opening, when the radial expansion effect bearing interior annulus, being not subjected to hoop tension, therefore outer toroid length is kept approximately constant, primary deformable shows as the Curvature varying of outer toroid, substantially flexural deformation.The transformation of the deformation pattern that hatch frame brings, substantially reduce the radial dilatation rigidity of outer toroid, it is allowed to outer toroid can have bigger Curvature varying, and corresponding is dramatically increasing of axial buffer displacement, the most simultaneously, the reduction of rigidity will necessarily bring the decline of cushion effect.And ring spring original conical surface friction power consumption mechanism is same effective in this utility model, it is meant that newly-designed opening tensioner ring formula energy dissipation spring still has the power consumption damping characteristic of brilliance, and here is omitted.
This utility model includes three kinds of parts such as annulus in single conical surface, annulus in Double-conical-surface, open type outer toroid.Can need to select multiple unit assembled in series according to stroke, two ends are annulus in single conical surface, and centre is that annulus is alternately arranged in open type outer toroid and Double-conical-surface.In single conical surface, in annulus and Double-conical-surface, annulus is closed configuration, and its outer surface contains one and two conical surfaces respectively；And open type outer toroid has an otch at hoop, inside it, two ends are respectively arranged with a conical surface.Require that all parts frustoconical bevel angle are the most equal, to ensure to coordinate, simultaneously in order to realize automatically reseting, in addition it is also necessary to guarantee that frustoconical bevel angle is more than angle of friction, typically can be taken between 12 degree～30 degree.Select appropriate inner circle ring thickness, make inner circle ring stiffness be significantly greater than open type outer toroid.
During use, applying axial compression load at two ends, inside and outside annulus mutually extrudes, and device axial dimension shortens.Because the stiffness difference of inside and outside annulus, interior Deformed ring can be ignored, and deforms and is concentrated mainly on open type outer toroid.In loading procedure, open type outer toroid girth is kept approximately constant, and only curvature is along with loading change, and material is mostly in flexural deformation mode, hence it is evident that phenomenon is that opening part gap is increasing.During unloading, open type outer toroid elastic return, opening part gap progressively reduces until restoring to the original state.In adding uninstall process, producing frictional force between inside and outside annulus, effect increases axial force when showing as loading, and reduces axial force, all play the effect of dissipation energy during unloading.
Open type outer toroid in this utility model, it can be single opening annulus, can also be that multiple open circular nests together composition combination type outer toroid, wherein the opening annulus of innermost layer has the inner conical surface for coordinating, and also want between inside and outside layer split ring to be formed radially cooperation, the expanding effect of annulus in transmission in time.
