Title: Structure for fitting high damping steel plate
Inventor: ASAI SEIJI
IPC: F16F15/02
Filed: 1987-07-22
Abstract: PURPOSE:To reduce the number of stages and to improve the external appearance and quality by forging a projecting part on a steel plate to constitute a high damping steel plate and bringing the surfaces into contact with each other and then, performing the electric resistance welding of the high damping steel plate to a member to be fitted. CONSTITUTION:The projecting part 8 is formed on one steel plate 2 of two conductive steel plates to form the high damping steel plate in advance as a welding place at the time of forging. The member 5 to be fitted is placed on the high damping steel plate 1 on a fixed electrode 6 and electrified. Since the projecting part 8 short-circuits between the steel plates 2 and 3 of the high damping steel, the high-damping steel plate 1 is firmly joined to the member 5 to be fitted. By this method, the need to use short-circuit fittings and the stage to melt a viscoelastic body 4 are entirely eliminated. Further, the welding placed is not exposed to the surface. Accordingly, the number of stages on the whole is reduced and the external appearance and quality are improved.
