摘要： A vibration-proof grip device is disclosed, which includes a first mass body coupled to a source of vibrations such as a machine drill, a leg drill, a pitching hammer, etc. via a first elastic member made of rubber or the like. A cylindrical grip member is mounted on the first mass body via a second elastic member made of rubber or the like A second mass body is mounted on the grip member, and an impact mass body is provided in the grip member such that it can strike the inner walls of the grip member. Vibrations transmitted from the vibration source are attenuated by the first elastic member, but the first mass body still is vibrated substantially at the same phase as the original vibrations of the vibration source The modulus of elasticity of the first and second elastic members and/or mass of the first and second mass bodies and impact mass body may be suitably selected such that the. grip member, to which vibrations are transmitted from the first mass body, constitutes a node of vibrations, i.e., it is vibrated at the opposite phase to the first mass body. When the vibration frequency of the vibration source varies, the collision of the impact mass body has an effect of attenuating resultant vibrations of the grip member.

摘要翻译： 公开了一种防振夹持装置，其包括通过由橡胶等制成的第一弹性构件而耦合到振动源的第一质量体，例如机械钻，腿钻，俯仰锤等。圆柱形 夹持构件通过由橡胶等制成的第二弹性构件安装在第一质量体上。第二质量体安装在夹持构件上，并且冲击质量体设置在夹持构件中，使得其能够撞击内壁 的握持构件。 从振动源传递的振动由第一弹性构件衰减，但是第一质量体仍然基本上与振动源的原始振动相同的相位振动。第一和第二弹性构件的弹性模量和/或质量 可以适当地选择第一和第二质量体和冲击质量体，使得从第一质量体传递振动的握持构件构成振动节点，即，以与第一质量体相反的相位振动 群体 当振动源的振动频率变化时，冲击质量体的碰撞具有衰减握持构件的合成振动的效果。
