Abstract
The utility model discloses a high damping helical spring, wherein, the helical spring is compactly filled with the wasted metal floss wires with high friction damping property. The two end openings of the spring filled with wasted metal floss wires or all part are immersed and affixed with elastic plastic material with high friction damping property, so that the spring produces high damping while in vibration. Therefore, the utility model greatly improves vibration insulating or vibration reducing performances, shortens the response time and process to vibration, increases the vibration absorbing performance and enlarges the effective vibration reducing range as well as lowers the producing cost.
Description
Technical field
The utility model relates to helical spring, especially a kind of high damping spiral spring.
Background technique
Existing all helical compression springs or coil expander, therefore its damping constant is all very little, also has some problems in use, and long as the weakening time-histories, the absorbing energy consumption is little, to low-frequency excitation vibration isolating effect difference etc.
Summary of the invention
The utility model provides that damping constant is big, the high damping spiral spring of low cost.
The utility model is closely to fill up the big waste material metal sleave of frictional damping in helical spring (comprising helical compression spring and coil expander).
Soak into the big elastoplastic material of viscous damping at the both ends of the spring mouth that fills up the big waste material metal sleave of frictional damping.
All soak into the big elastoplastic material of viscous damping at the spring that fills up the big waste material metal sleave of frictional damping.
The beneficial effects of the utility model are: owing to closely fill up the big waste material metal sleave of frictional damping in the spring, or in the metal sleave, dose the big elastoplastic material of viscous damping again, and make spring when vibration, produce very big damping.Therefore it improves vibration isolation or damping property greatly, shortens the vibratory response time-histories, increases the absorbing energy consumption, enlarges effective vibration damping frequency domain, and is cheap.
Description of drawings
Fig. 1 is the novel structural representation of this reality;
Fig. 2 is an another kind of structural representation of the present utility model;
Fig. 3 is another structural representation of the present utility model.
Embodiment
As shown in Figure 1, in helical spring 1, closely fill up the big waste material metal sleave 2 of frictional damping.
As shown in Figure 2, soak into the big elastoplastic material of viscous damping 3 in spring 1 two-port of the waste material metal sleave 2 that fills up frictional damping.
As shown in Figure 3, the spring 1 at the waste material metal sleave 2 that fills up frictional damping all soaks into the big elastoplastic material of viscous damping 3.
If during multilayer intussusception helical spring, the common spring of intussusception multilayer outside spring 1.
The waste material metal sleave 2 that described frictional damping is big is general stainless steel working discard wire.
The elastoplastic material that described viscous damping is big is pitch and French chalk, and waste Crumb rubber adds property-modifying additive again, as mixs such as polythene tire, triblock polymer, random polypropylene, the stupid rubber of fourth.
