摘要： An impact tool includes a housing, a motor supported within the housing, a drive assembly configured to convert a continuous rotational input from the motor to intermittent applications of torque on a workpiece, and first and second impact members supported on the drive assembly and configured to deliver impacts to one another. The first impact member includes a core made of a first material having a first hardness, and a sleeve surrounding the core and made of a second material having a second hardness different than the first hardness. The first hardness is less than the second hardness.

摘要： A rotary hammer has a hammer body with an electric motor section which comprises a receiving section for receiving transmission mechanisms in a frame which serves as a shell barrel. A driving electric motor is installed in the shell barrel. The body also has a vibration and transmission mechanism section in which the transmission mechanisms including the motion conversion transmission mechanism and the vibrating mechanism are held by a bracket removably connected to the frame. In addition, the hammer body has a tool holding section in which the tool holding member for concomitantly rotatably holding the tool is rotatably supported by a bracket removably connected to the frame. The three sections are so arranged that they can be assembled and disassembled individually as separate component units.

摘要： A locking ring impactor apparatus is a modular tool housing used to rotate the locking rings of centrifuges, pressure vessels, or other industrial equipment using conventional power tools. The locking ring impactor apparatus utilizes an impacting tool mounted to an armature with a recoil damper assembly. The armature receives and supports the impacting tool while the recoil damper assembly absorbs and mitigates the recoil forces generated by the impacting tool. A tool adapter is mounted between the impacting tool and a locking ring with at least one tensile member being engaged between the tool adapter and the recoil damper assembly. The at least one tensile member is configured to apply tension between the tool adapter and the recoil damper assembly to ensure that the force of the impacting tool is directed towards rotating the locking ring instead of vibrating the armature in-place.
