High-thrust driving vibration isolation device

Abstract

The invention relates to a high-thrust driving vibration isolation device. The high-thrust driving vibration isolation device comprises a top plate and a bottom plate. The top plate and the bottom plate are connected through guide pillars and guide sleeves, and the guide pillars are inserted into the guide sleeves. U-shaped baffles are installed on the portions, close to the edges, of the upper surface of the bottom plate, openings of the U-shaped baffles are upward, and magnets are fixedly installed on the inner sides of the U-shaped baffles. Wire winding steel plates which extend downwards are fixedly installed on the lower surface of the top plate, stretch into the U-shaped baffles, and are connected with a power source. The high-thrust driving vibration isolation device is designed according to the linear motor principle, a Halbach type permanent magnet matrix is adopted by the magnets, energized coils generate upward thrust under the action of the high-intensity magnetic field to partially counteract the downward gravity, and therefore vibration reduction is achieved, and the vibration reducing effect of the high-thrust driving vibration isolation device is remarkable; compared with an electromagnetic facility with the size equal to that of the high-thrust driving vibration isolation device, the high-thrust driving vibration isolation device has the advantage that the output force of the high-thrust driving vibration isolation device can be increased by 2-5 times; and due to the fact that a vibration amplitude adjusting device is adopted, the amplitude of vibration reduction can be adjusted according to different environments, and the application range of the high-thrust driving vibration isolation device is greatly broadened.

Description

technical field [0001] The invention relates to a vibration isolation device, in particular to an active vibration isolation device. Background technique [0002] Nowadays, during the production operation of many industries, devices such as high-power motors will generate large vibrations, which will shorten the service life of the equipment itself and reduce the working accuracy of the equipment. At the same time, on the one hand, the vibration will be transmitted to other nearby equipment through the base or foundation, causing the same impact on other equipment; People have just begun to use vibration reduction and vibration isolation devices. [0003] The vibration reduction and vibration isolation devices currently on the market generally use springs and hydraulic vibration reduction, and the vibration reduction effect is not obvious. Contents of the invention [0004] Aiming at the deficiencies in the above-mentioned prior art, the applicant conducts research and i...
