Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
Protect the method for work medi-spring and realize the device of the method, its feature is as follows:
A. install: the part that fixed plate 5 is scaffold, on it, be processed with manhole, select spring 3 and another kind of stiffness coefficient to be greater than the elastic member of the stiffness coefficient of selected spring 3, mandrel 4 is through the manhole of fixed plate 5, on described spring 3 and elastic member suit mandrel 4, and the termination of these two parts is fixedly mounted on respectively the two sides of fixed plate 5, and the other end of spring 3 is fixedly mounted on upper plate 2, through the mandrel 4 of upper plate 2, on mandrel 4, be processed with screw thread; Nut 1 is arranged on mandrel 4 by screw thread; The other end of mandrel 4 is fixedly connected with by lower roof plate 7 and with lower roof plate 7.
B. afterburning: to calculate the required maximum weighted of bearing of spring 3, screw nut 1, apply maximum weighted by upper plate 2 to spring 3; Fixing at afterburning rear fixed plate 5, lower roof plate 7 is affixed with mandrel 4; Fastening nut 1, applies precompression F to spring 3, and spring 3 compresses, and after compression, length is L, another elastic member compression, and F is stressed;
C. spring 3 telescopic variation: apply to the power of lower roof plate 7 directions to mandrel 4, now, mandrel 4 pulls lower roof plate 7, the power being subject to when mandrel 4 progressively adds to F from 0, the pressure of this another elastic member of process is reduced to F[1-K/ (K+k1) gradually from F], the length L of the length of spring 3 after by precompression gradually becomes L-F/(K+k1); Unload to mandrel 4, from progressively to 0 of F, the pressure of another elasticity part is from F[1-K/ (K+k1)] become gradually F again, the length of spring 3 is from L-F/(K+k1) become L again.
The stressed variation of spring 3: apply to the power of lower roof plate 7 directions to mandrel 4, now, mandrel 4 pulls lower roof plate 7, the suffered power F upwards of upper plate 2 increases gradually, the power being subject to when mandrel 4 progressively adds to F from 0, and the stressed of spring 3 is increased to F+FK/(K+k1 gradually from F), unload to mandrel 4, from progressively to 0 of F, spring 3 stressed from F+FK/(K+k1) F falls back gradually.This process spring stress fluctuation amplitude FK/(K+k1).Regulate K and k1 can obtain the fluctuation amplitude needing.
A kind of device that utilizes said method protection spring 3, comprise nut 1, upper plate 2, spring 3, mandrel 4, fixed plate 5, another elastic member, lower roof plate 7, it is characterized in that: the part that fixed plate 5 is scaffold, on fixed plate 5, be processed with manhole, select spring 3 and another kind of stiffness coefficient to be greater than the elastic member of the stiffness coefficient of selected spring 3, mandrel 4 is through the manhole of fixed plate 5, on described spring 3 and elastic member suit mandrel 4, and the termination of these two parts is fixedly mounted on respectively the two sides of fixed plate 5, the other end of spring 3 is fixedly mounted on upper plate 2, be processed with screw thread through on the mandrel 4 of upper plate 2, nut 1 is arranged on mandrel 4 by screw thread, the other end of mandrel 4 is fixedly connected with by lower roof plate 7 and with lower roof plate 7.
As long as stiffness coefficient is greater than material or the parts of selected spring 3, all optional another elastic members that is used as.But in using process, rubber spring 6 is because of its good springiness and have certain hardness, often selected.
When the method in the present invention and device are during for the damping of the traffic tool; described mandrel 4 can be the damper cylinder of the traffic tool; in the time that traffic tool institute walking along the street line is uneven; damper cylinder is with respect to the motion up or down of axis of orientation; all pull upper plate 2 and lower roof plate 7, spring 3 is stressed to diminish, and another elasticity part has been shared pressure; both reach damping effect, also realized the protection to spring 3.
In the time that the method in the present invention is used for the damping of hoisting object process, mandrel 4 serves as suspension rod, has protected spring 3 when realizing shock-absorbing function.
The description of " downwards " isotropy in the present invention is only described corresponding technical characteristics for convenience, in actual use, as long as meet relative position, installation, stressed relation between each component, can realize the effect of protection work medi-spring.
Protection scope of the present invention is not limited only to the disclosed technological scheme of embodiment part; all utilization first adds the suffered maximum power of spring in advance to spring, and the technological scheme of then utilizing another elastic member to share the suffered power of spring all falls into protection scope of the present invention.
