Embodiment Construction

[0011] Such as figure 1 As shown, the helical spring 1 is tightly packed with scrap metal messy wires 2 with large frictional damping.

[0012] Such as figure 2 As shown, the elastic-plastic material 3 with large viscous damping is soaked in the two ports of the spring 1 filled with scrap metal messy wires 2 for frictional damping.

[0013] Such as image 3 As shown, the spring 1 filled with scrap metal messy wires 2 for frictional damping is completely soaked in the elastic-plastic material 3 with large viscous damping.

[0014] If it is a multi-layer nested coil spring, multi-layer ordinary springs are stacked outside the spring 1.

[0015] The scrap metal messy wire 2 with large frictional damping is general stainless steel processing scrap metal wire.

[0016] The elastic-plastic material with large viscous damping is asphalt, talcum powder, waste rubber powder, and modified additives, such as polyethylene tire, tri-block polymer, random polypropylene, butadiene rubbe...

Abstract

The present invnetion discloses a highly damped helical spring, which is characterized by that the interior of helical spring is lightly filled up with waste metal disorder wires with large friction damping, then two end of the spring filled up with metal disorder wires or its whole body can be impregnated with elastic-plastic material with large viscous damping to make spring produce large damping when said spring is vibrated, so that it can greatly improve vibration isolation and vibration-damping performance, and can shorten the vibration response time increase vibration-absorbing energy consumption and expand effective vibration-reducing frequency domain, and its cost is low.

Description

technical field [0001] The invention relates to a helical spring, especially a high damping helical spring. Background technique [0002] All existing helical compression springs or helical tension springs have very small damping coefficients, so there are some problems in use, such as long time for vibration elimination, low energy consumption for vibration absorption, and poor vibration isolation effect for low-frequency excitation. Contents of the invention [0003] The invention provides a high-damping helical spring with large damping coefficient and low manufacturing cost. [0004] In the present invention, the helical spring (comprising a helical pressure spring and a helical tension spring) is tightly packed with scrap metal messy wires with large frictional damping. [0005] The elastic-plastic material with large viscous damping is soaked in the two ports of the spring filled with scrap metal messy wires with large f...
