摘要： An electric hand power tool with oscillating working movement, particularly translation movement, is made particularly compact and with low volume by an elastomeric module. The elastomeric module expands and/or contracts when electric voltage is applied, and is used as a drive for the hand power tool. The elastomeric module is coupled mechanically to a tool and is coupled electrically to a voltage source.

摘要： A reciprocating saw including a housing, a motor supported by the housing, a spindle mounted for reciprocation relative to the housing and having a front end for supporting a saw blade, the spindle being movable through a cutting stroke and a return stroke, the cutting stroke having a stroke length, and a pivot body interconnecting the spindle and the motor. The position of the pivot axis of the pivot body may be movable relative to the housing to change the stroke length of the spindle. A shock absorber may be operatively positioned between the motor and the front end of the spindle and may be at least partially mounted within the spindle.

摘要： A drive gear is mounted for rotation in a plane parallel with the axis of rotation of the output member of the motor. The gear includes an annular series of beveled gear teeth in meshing engagement with beveled pinion teeth on the end of the motor output member. The drive gear includes a crank pin roller and an annular cam surface eccentric to the axis of rotation of the gear. The roller is received within a rectilinear slot in the plunger assembly thereby defining a scotch-yoke drive for reciprocating the plunger assembly. The plunger assembly includes planar cam follower formations engaged by the annular cam surface to provide an oscillating component of movement to the plunger assembly. The crank pin mounts a disk in eccentric relationship to the drive gear; this disk supports another crank pin and roller. A counterweight having a mass substantially the same as the plunger assembly has a rectilinear slot receiving the last-mentioned roller thereby constituting a second scotch-yoke drive for reciprocating the counterweight. The counterweight includes planar cam follower surfaces engaged with peripheral portions of the disk thereby imparting an oscillatory component to movement of the counterweight.

摘要： A scroll or jigsaw of the walking beam type is disclosed in which the upper and lower beams or arms are of hollow, tubular construction so as to have sufficient rigidity to resist up and down vibrational movement, and so as to permit lateral cutting. The beams are mounted in a pair of identical die cast frame members, and the drive motor is mounted directly to the rear of the frame members. The motor is connected to the rear ends of the beams for reciprocably driving them. The frame members, together with the motor, are pivotally mounted relative to a base or table frame thereby to permit angling of the saw blade (as opposed to tilting the table) for bevel cuts.

摘要： A drive system for a reciprocating blade saw wherein a motor rotates an eccentric which rocks a bell crank to reciprocate the saw blade, the eccentric and the bell crank being associated with masses which rotate and rock 180.degree. out of phase with the eccentric and bell crank and are so proportioned as to counterbalance those elements and minimize the vibration of the system. The counterbalancing masses are divided and mounted each side of the working elements so that no lateral torque forces are developed.

摘要： A drive arrangement for a portable reciprocating power saw or the like including a crankshaft having a pair of closely spaced opposed crank throws and connecting rods attached to each throw. One connecting rod is connected to a tubular reciprocating blade drive member and the other connecting rod is connected to a cylindrical counterweight slidably housed in telescoping relationship within the tubular blade drive member. The saw blade drive member and counterweight reciprocate in opposite directions along a common axis and the saw blade drive member also serves as a bearing support for the counterweight.

摘要： There is provided a power tool in which impact applied to a power transmission portion can be mitigated to thereby suppress components constituting the power transmission portion from being deformed and damaged. The power tool includes a brushless motor 3 having a rotation shaft portion 31 rotatable about a rotation axis A1, a housing 2 accommodating therein the brushless motor 3, a power transmission portion 6 configured to receive a rotation force of the rotation shaft portion 31 and to transmit a driving force based on the rotation force, and a driven portion 7 configured to be driven by receiving the transmitted driving force. The rotation shaft portion 31 is supported by the housing 2 so as to be movable relative to the housing 2 in an axial direction of the rotation axis A1.

摘要： A linear saw, machining method using the same and numerical controlled machining device. The linear saw has: a machining part (1), for cutting a machining object in a linearly extending direction of the linear saw, and generating a slot on the machining object; and the linear saw further includes a space-keeping part (2) arranged such that the whole linear saw does not contact the slot or is not subject to an acting force of the slot when the space-keeping part passes through the slot. As the linear saw is provided with a space-keeping structure, the linear saw has time and space to recover from a deformation generated by cutting the machining object, thus effectively preventing accumulated errors, and greatly improving the position precision of the machining seam.
