INERTIAL MASS FOR VIBRATION ISOLATORS

摘要

An inertial mass (50) for a vibration isolator (20) having an attachment fitting (22) adapted for rotation about an axis (16) and a spring (40) adapted for rotation with the attachment fitting (22). The inertial mass (50) is characterized by a pair of segments (52) each having a generally Z-shaped cross-sectional configuration. More specifically, each segment (52) defines a central web (54), a first leg (56) projecting radially inboard of the central web (54) and a second leg (58) projected radially outboard of the central web (54). The first and second legs (56, 58) are integral with the central web (54) and the second legs (58) are adjoined along a mating interface (I) to define the assembled inertial mass (50). As assembled, the inertial mass (50) is adapted for being mounted in combination with the spring (40) of the vibration isolator (20). Preferably, the second legs (58), in combination, define a mating flange (62) which is adapted for mounting at least one tuning weight (64), and, the first legs (56) define circular abutment surfaces (68) adapted for coacting with an opposing abutment surface (70) of the attachment fitting (22).
