초록

A vibration reduction and lubricating mechanism for a powered hammer includes a power driven piston in a cylinder that reciprocatingly drives a ram, which repetitively strikes a beat piece, which repetitively strikes a tool received in a tool holder. The vibration reduction and lubricating mechanism includes a first chamber defined in a housing of the powered hammer. A second chamber is defined within an end portion of the cylinder facing the beat piece, forward of the ram. A passageway is in communication with the first and second chambers. A counter m...

청구항

The invention claimed is: 1. A powered hammer comprising: a housing; a tool holder coupled to the housing which is capable of holding a tool; a motor within the housing; a cylinder within the housing; a piston slideably received within the cylinder; a drive mechanism which converts rotary output of the motor into a reciprocating motion of the piston within the cylinder; a ram slideably mounted within the cylinder, forward of the piston, and which is reciprocatingly driven by the piston; a beat piece support structure that supports a beat piece, the beat...
