摘要: Disclosed is a diamond saw capable of reducing noise by installing a damper for absorbing vibration in a shank. The low noise diamond saw comprises: a shank formed of a circular metallic plate; and a diamond blade bonded to an outer circumferential surface of the shank, in which a damper is partially bonded to one or both of upper and lower surfaces of the shank by a spot welding. Said one or both of the upper and lower surfaces of the shank may be provided with recesses having a thickness enough for an uppermost portion of the damper not to be higher than an uppermost portion of the diamond blade According to another embodiment of the present invention, a low noise diamond saw comprises: a shank formed of a circular metallic plate; and a diamond blade bonded to an outer circumferential surface of the shank, in which a plurality of recesses having a predetermined depth are formed in upper and lower surfaces of the shank in correspondence with each other in a circumferential direction, a hole having a diameter smaller than that of the recess is formed in the recess, and a damper is mounted in the hole so that a clearance may not be generated between a surface of the recess and a surface of the damper. In the diamond saw, noise is reduced as the number of the dampers is increased.

摘要: The present invention relates to a damping structure which is capable effectively damping vibration of a structure. The damping structure includes a vibration controlling medium fixed at a structure and vibrating with an amplitude greater than that of the structure upon vibration and a damper vibrating separately from the vibration controlling medium as a result of being loosely fitted into the vibration controlling medium or a damper supporter extended therefrom, and thus having a vibration frequency different from that of the vibration controlling medium.

摘要: A new shrink fitting method including deformation is disclosed, in which a high bonding force can be obtained without accurate mechanical process such as forming an insertion body having an outer diameter greater than an inner diameter of an object for receiving the insertion body. The shrink fitting method comprises preparing a pipe and a rod material whose inner and outer diameters are different from each other; bonding the pipe and the rod material to each other in a state that the pipe or the rod material is deformed by heating; deforming the pipe to allow the inner diameter of the pipe to be equal to the outer diameter of the rod material; and cooling the bonded pipe and rod material. The shrink fitting method can be widely used for various mechanical parts.
