Description

technical field [0001] The invention relates to a wire rope vibration isolator, which is a combined all-metal wire rope vibration isolator which is especially suitable for vibration isolation, noise reduction and impact isolation of military industry, electrical equipment and various types of machinery. [0002] Background technique [0003] The vibration isolator is an elastic element connecting the equipment and the foundation to reduce and eliminate the vibration force transmitted from the equipment to the foundation or the vibration and impact transmitted from the foundation to the equipment. [0004] In practical engineering, mechanical vibration often has harmful effects on the structure, performance and life of mechanical equipment. Isolating vibration and dampening shocks comes into focus. A variety of vibration isolation devices have been designed and applied, especially the development of wire rope vibration isolators with excellent performance has become more an...

AI Technical Summary

Problems solved by technology

The processing technology is complex, the accuracy is difficult to guarantee, and the vibration isolator will be torsion during the static deformation process. In engineering applications, the vibration isolation body will rotate, and the stiffness is different in each direction. The vibration isolation system installed horizontally requires special attention in the design. Considering the installation combination of the vibration isolator in the horizontal direction makes the design and installation of the vibration isolation system more complicated

Although the design of the drum-shaped vibration isolator has considered the problem of horizontal stiffness symmetry, the structure is relatively complex, the processing accuracy is high, the processing technology is relatively complicated, and the cost is high.

Moreover, after the design and processing of these two types of wire rope vibration isolators, the working characteristic curve of the vibration isolator under specific working conditions, the frequency response curve of the vibration isolator, and the natural frequency and other characteristics cannot be changed. It is difficult to install and disassemble and maintain. If a link is damaged, the entire wire rope needs to be replaced

subject to certain limitations in engineering applications

Some people also use independent steel wire rope rings as vibration isolators. The processing of the ring is to clamp an aluminum fixed clamping sleeve at both ends of the steel wire rope to fix it. This kind of processing method is difficult to form the ring, and the two ends of the ring are easy to slip off. reverse

Not suitable for working under medium and heavy loads

In addition, the upper and lower splints adopt an integral structure, the assembly method is single, and it is difficult to disassemble and maintain
