Rotary impact tool, shock attenuating coupling device for a rotary impact tool, and rotary impact attenuating device |
摘要 |
A shock attenuating coupling device is provided for a rotary impact tool for drivingly connecting a hammer mechanism to a drive anvil. The shock attenuating coupling device includes a first coupling member, a second coupling member, and a body of resilient material. The first coupling member has a longitudinal drive portion with an input end configured to couple for rotation with a hammer mechanism and an output end with a first jaw portion. The second coupling member has an output end configured to couple for rotation with a drive anvil and an input end with a second jaw portion configured to cooperate in longitudinally overlapping and circumferentially spaced-apart relation with the first jaw portion. The body of resilient material is interposed between the first jaw portion and the second jaw portion. A rotary impact tool with the shock attenuating coupling device is also provided.
