摘要： PROBLEM TO BE SOLVED: To sufficiently supply lubricating oil to components of a hammer drill.
SOLUTION: This hammer drill such as a pavement breaker includes a housing, a tool holder, a motor, a cylinder, a piston, a drive mechanism for converting a rotary output of the motor into a reciprocating motion of the piston, the lubrication fluid, a ram reciprocatingly driven by the piston, a beat piece repetitively striking an end part of a tool to transfer the momentum of the ram to the tool, and a rear piston chamber for moving the lubrication fluid to the surrounding in the housing by the movement of air when the piston is reciprocatingly driven. The drive mechanism includes crank mechanism and con rod including crank shaft and drive pin. The crank shaft and/or the drive pin includes the longitudinal direction passage of air and the lubricating fluid to assist the movement of the lubrication fluid in the housing.

摘要： The power saw has a housing (1) which encloses an electric motor mounted with its axis vertical. The motor shaft has a pinion which drives a gear wheel. The latter rotates about a vertical axis and is fitted with two diametrically opposite crankpins. One crankpin projects upwards, and the other one projects downwards. Each pin engages a Scotch yoke, to which a horizontally mounted sawblade (7) is attached. The two blades are mounted side by side in guides and move in opposite directions to each other.

摘要： The electrically driven saw has two parallel, reciprocating blades (7) alongside each other, coupled to holders (15,18) at their rear ends with longitudinal shoulders along their outer surfaces, extending away from the teeth. A guide plate (6) has two support portions alongside each other, forming a slot for the blades. The bottom edges of the current portion form locations for the shoulders. The guide plate has a bending torque resistance of between 7.5 and 30 times that of a saw blade. The support portions are pref. arranged to exert a torque pressing the blades together at the teeth.
