Abstract
The utility model relates to a damper with zero-stiffness toothed disk springs and belongs to structural fields of compensators used for compensation of automotive stretchers, carrier vehicles, constant hangers and cables. The damper comprises an outer guiding drum, a bottom plate and a sliding head. The multiple disk springs are arranged between the sliding head and the bottom plate. The two adjacent disk springs are arranged reversely. Multiple radial grooves are arranged in each disk spring along a peripheral direction. A separating piece is arranged between the two adjacent disk springs and the periphery of each separating piece is integrally provided with a sliding block, the outer surface of which is a spherical surface. The outer surface of each sliding block is in a slip fit relationship with the inner surface of the outer guiding drum. The outer edge of each disk spring is arranged inside of each corresponding sliding block. The damper with the zero-stiffness toothed disk springs has following beneficial effects: due to the fact that the radial grooves are arranged in the disk springs, the disk springs do not reverse when being used; the separating piece is arranged between the two adjacent disk springs and does not occlude during operation; and the outer surface of each sliding block is a spherical surface, thus reducing friction between each spherical surface and the inner surface of the outer guiding drum and overcoming a friction force during application and improving comfortableness.
Description
Technical field
The utility model relates to the structure fields such as compensator of Vehicular stretcher bed, carrier vehicle, constant hanger, cable compensation use.
Background technique
In prior art, have a kind of dish spring vibration damper, its publication number is 201747841U, mainly comprises outer sleeve, dish spring, pressing plate, suspension rod bolt, dish spring is set on suspension rod bolt and by pressing plate and nut and is pressed on the base plate in outer sleeve, and suspension rod bolt hangs head and extends outside sleeve.When the interior cone height of the dish spring of this vibration damper and its Thickness Ratio are more than or equal to, spring has zero stiffness characteristic, when dish spring reaches certain load, even if the distortion of dish spring continues to increase, its load also substantially no longer changes, but this dish spring easy flange in use, in mechanical field, load-deflection curve produces shake, sudden change, and such spring can not be used as elastic device traditionally.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and the band tooth dish spring zero stiffness vibration damper that a kind of dish spring can flange is provided.
The purpose of this utility model is achieved in that band tooth dish spring zero stiffness vibration damper, comprise outer guide, one end connecting bottom board of outer guide, the other end of outer guide places a slide head, several dish springs are set between slide head and base plate, adjacent two dish spring reversed arrangement, in each dish spring, several radial grooves are along the circumferential direction set, between adjacent two dish springs, spacer is set respectively, the periphery of each spacer is wholely set respectively slide blocks, the outer surface of each slide blocks is respectively sphere, the outer surface of each slide blocks is slidably matched with the internal surface of outer guide respectively, the outward edge of each dish spring is separately positioned on the inner side of corresponding slide blocks.
The utility model by along the circumferential direction arranging several radial grooves in each dish spring, can flange during use, between adjacent two dish springs, spacer is set respectively, during use, just can not sting tooth, and because the outer surface of each slide blocks is respectively sphere, reduce the friction with the internal surface of outer guide, overcome the frictional force while using, improve comfort level.The utility model can be widely used in the place that Vehicular stretcher bed, carrier vehicle, sick year vehicle, constant hanger, precision type instrument platform, cable compensation etc. need suspention and support.
The utility model uses the zero stiffness curve characteristic with tooth belleville spring, selects its change in displacement district, meets the demand of large displacement with serial fashion, has overcome common dish spring h0/t >=highly unstable defect.And band tooth dish spring spacer upper and lower guide and limit outer end semicircular structure, is reduced frictional force between dish spring and the frictional force between dish spring and outer sleeve, to reduce the noise in vibration damper work and to increase comfortable feel.
In order to alleviate the weight of spacer, the middle part of each spacer axially arranges respectively through hole.
In order to alleviate the weight of slide head, lightening core is set in slide head.
In order to facilitate slide head to be connected with miscellaneous equipment, one end that slide head stretches out outer guide axially arranges tapped hole.
While being connected with miscellaneous equipment for anti-skidding head, rotate, one end that slide head stretches out outer guide is wholely set square boss.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of dish spring.
Fig. 3 be in Fig. 2 A to view.
