Adjustable permanent magnet vibration reduction device

Abstract

The invention discloses an adjustable permanent magnet vibration reduction device which comprises an upper fixed seat and a lower fixed seat. A rotating shaft is movably mounted on each fixed seat. The ends, away from adjusting knobs, of the rotating shafts are fixedly connected with driving gears. Permanent magnets are fixedly mounted on moving blocks and are movably mounted in adjusting seats. Rotating seats are movably mounted at the two ends of each adjusting seat. A cooperation permanent magnet is fixedly mounted on each rotating seat. The upper cooperation permanent magnet and the lowercooperation permanent magnet of each adjusting seat are connected through a limiting groove. A rubber telescopic air cushion is fixedly mounted between the upper fixed seat and the lower fixed seat, and a vibration reduction spring is further fixedly mounted between the upper fixed seat and the lower fixed seat. According to the adjustable permanent magnet vibration reduction device, three vibration reduction manners of the spring, an airbag and the permanent magnets are adopted, vibration can be reduced without powering on, wear generated by friction of the magnets and the inner wall can be avoided by means of the inclined arrangement structure, the vibration reduction strength of the device can be adjusted by adjusting the positions of the permanent magnets, and the device is effectivelysuitable for being used in various vibration environment and is suitable for being widely popularized.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices, in particular to an adjustable permanent magnet shock absorbing device. Background technique [0002] A shock absorbing device with the application number of "CN201711098452.8" in the prior art includes a main shock absorbing device, and buffer devices are provided at both ends of the main shock absorbing device; the main shock absorbing device includes a sleeve, and the Both sides of the sleeve pipe wall are symmetrically provided with travel grooves, and the inner two ends of the sleeve are respectively provided with a first electromagnet and a second electromagnet, and the first electromagnet and the second electromagnet are arranged concentrically. And the polarities of the first electromagnet and the second electromagnet repel each other, and the two side walls of the first electromagnet and the second electromagnet are all symmetrically fixedly connected with connecting rods...

AI Technical Summary

Problems solved by technology

[0003] But above-mentioned this shock-absorbing device still has comparatively obvious defective in use: 1, above-mentioned device utilizes spring and magnet as shock-absorbing device, and shock-absorbing effect is limited; Electric energy is contrary to the current concept of energy saving and environmental protection; 3. The magnets of the above device are placed opposite to each other for shock absorption. Under high pressure, the magnets placed opposite are easy to shift to one side, so that the electromagnet and the sleeve Friction occurs, which will easily lead to wear of the electromagnet in the long run
