Abstract
The utility model discloses a kind of compound disc spring group, be formed by stacking by multiple belleville springs, it is characterized in that: also comprise guide pipe, pilot sleeve, described guide pipe runs through described superimposed belleville spring, the external diameter of guide pipe is more smaller than the internal diameter of belleville spring, and the two ends of guide pipe are provided with limiting stopper, and described limiting stopper is limited to pilot sleeve in guide pipe with belleville spring, the end of guide pipe is connected with pilot sleeve inwall, and pilot sleeve and guide pipe are suppressed belleville spring jointly.In the time that guide pipe upwards compresses, the relative guide pipe of pilot sleeve bottom is pushed, make belleville spring compression, in the time that extruding finishes, belleville spring restores to the original state, and under the effect of confinement block, keeps certain pressure, avoids having dead zone between belleville spring group and pilot sleeve, this compound disc spring group is simple in structure, and using effect is good.
Description
Technical field
The utility model relates to butterfly spring technical field, relates in particular to a kind of compound disc spring group.
Background technique
Spring is as the basic part in machinery, existing belleville spring group is all in use by several belleville springs are superimposed together and are arranged in machine, but between each belleville spring, no matter be axially or radially not there is spacing fixing structure, between each cluster spring, there is height difference, install also inhomogeneous, easily produce dislocation extruding phenomenon, cause early failue, have a strong impact on the normal use of equipment, thereby cause machine run undesired and bring huge loss.
Summary of the invention
The utility model is to solve the technical problem existing in above-mentioned prior art, provides a kind of simple in structure, can effectively fix the compound disc spring group of belleville spring horizontal stroke, length travel, and its concrete technological scheme is as follows:
A kind of compound disc spring group, be formed by stacking by multiple belleville springs, it is characterized in that: also comprise guide pipe, pilot sleeve, described guide pipe runs through described superimposed belleville spring, the external diameter of guide pipe is more smaller than the internal diameter of belleville spring, and the two ends of guide pipe are provided with limiting stopper, and described limiting stopper is limited to pilot sleeve in guide pipe with belleville spring, the end of guide pipe is connected with pilot sleeve inwall, and pilot sleeve and guide pipe are suppressed belleville spring jointly.In the time that guide pipe upwards compresses, the relative guide pipe of pilot sleeve bottom is pushed, and makes belleville spring compression, in the time that extruding finishes, belleville spring restores to the original state, and under the effect of confinement block, keeps certain pressure, avoids having dead zone between belleville spring group and pilot sleeve.
As preferably, described limiting stopper is wedge shape, and described wedge shape is up big and down small, and more up, the internal diameter of its belleville spring is less with the gap, outside of wedge shape for the new spring of dish, until belleville spring can not continue up.
As preferably, described belleville spring is superimposed in the opposite direction, and superimposed mode is decided according to the actual requirements.
As preferably, described belleville spring is superimposed with equidirectional, and superimposed mode is decided according to the actual requirements.
As preferably, the degree of depth that described guide pipe enters pilot sleeve is not less than 4mm, and its actual grade is decided according to the actual requirements.
As preferably, the external diameter of described guide pipe, with the internal diameter gap 0.3mm of described pilot sleeve, is decided according to the actual requirements.
The beneficial effects of the utility model are: this compound disc spring group is simple in structure, and using effect is good, utilize the external diameter of guide pipe laterally to limit belleville spring, utilize the limiting stopper up and down of guide pipe longitudinally to limit belleville spring.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the superimposed structural representation of belleville spring equidirectional described in the utility model;
Fig. 3 is the superimposed structural representation of belleville spring opposite direction described in the utility model;
In figure, reference character is: 1-belleville spring, 2-guide pipe, 3-pilot sleeve, 4-limiting stopper.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.Obviously, described embodiment is only part embodiment of the present utility model.
As shown in Figure 1, a kind of compound disc spring group, is closed and is formed by multiple belleville springs folded 1, also comprise guide pipe 2, pilot sleeve 3, described guide pipe 2 runs through described superimposed belleville spring 1, and the external diameter of guide pipe 2 is more smaller than the internal diameter of belleville spring 1, avoids belleville spring 1 that laterally larger displacement occurs.The two ends of guide pipe 2 are provided with wedge shape limiting stopper 4, the biggest place width of described wedge shape limiting stopper 4 should be greater than the internal diameter of belleville spring 1, described wedge shape limiting stopper 4 is limited to pilot sleeve 3 in guide pipe 2 with belleville spring 1, the end of guide pipe 2 is connected with pilot sleeve 3 inwalls, pilot sleeve 3 and the common compacting belleville spring 1 of guide pipe 2.In the time that guide pipe 2 upwards compresses, pilot sleeve 3 relative guide pipe 2 bottoms are pushed, and belleville spring 1 is compressed, in the time that extruding finishes, belleville spring 1 restores to the original state, and keeps certain pressure under the effect of wedge shape confinement block 4, avoids having dead zone between belleville spring group and pilot sleeve 3.
As shown in Figure 2, described in this technological scheme, in belleville spring group, each belleville spring 1 carries out superimposed in the opposite direction; As shown in Figure 3, described in this technological scheme, in belleville spring group, each belleville spring 1 carries out superimposed with equidirectional; Its actual superimposed mode can be selected according to actual user demand, can keep good damping, buffering effect.
Above-described embodiment is preferably mode of execution of the utility model; but mode of execution of the present utility model is not restricted to the described embodiments; other are any does not deviate from the change of making under Spirit Essence of the present utility model and principle; modify; substitute, combination, simplifies; all should be equivalent substitute mode, all should be included in protection domain of the present utility model.
