Cylindrical vibration damping in front of the direction and method of making same and vibration damping structure including the cylindrical vibration damping structure

摘要

It is a process for the production of a cylindrical joint - vibration damping in front of the direction (10, 40, 70, 80, 90, 100, 110) is disclosed, comprising the steps of: establishing a elastic main - rubber body (16, 42, 48) of a hollow cylindrical shape, a suitable for mass production, installation joint (22) in an outer peripheral surface of the same is open, and a slot (30), which extends over its entire axial length; stretching of the elastic body (16, 42, 48) on the slot in order to allow the elastic body around a rod-shaped vibration element (12) through the slot (30) of a radially outer side to mount, so that the elastic body (16, 42, 48) a abutting inner surface (28, 46), which is in the position, with the vibration element (12) at a region in abutting contact with, where the radial distance between an inner peripheral surface of the elastic body (16, 42, 48) and an outer circumferential surface of the vibration element (12) is at a minimum; creating of a mass - element (18) separately from the elastic body, and fastening of the mass - element (18) on the elastic body (16, 42, 48) by means of fastening of the mass - element (18) at the suitable for mass production, installation joint (22).
