A LOOSE PREVENTING SYSTEM OF BOLT

摘要

According to an embodiment of the present invention, a system to prevent loosening of a bolt comprises: a bolt; a nut fastening a material between the nut and the bolt; a coil positioned in the bolt or the nut, and wound in a direction perpendicular to a circumferential direction of the bolt or the nut; and a power unit supplying power to the coil. The system to prevent loosening of the bolt in accordance with the present invention is able to fundamentally block a large malfunction factor generated due to loosening of the bolt by fundamentally preventing loosening of the bolt with electronic power; thereby efficiently saving costs caused by a malfunction, and permanently maintaining a high quality of coupling.
