摘要： A handheld oscillation machine tool has support devices for maintaining a spacing between internal parts and an outer housing. The support devices are arranged in pairs of first and second support devices. One support device in each pair has a concave circular surface, and the other has an opposed convex circular surface. Elastically deformable damping elements are arranged between the pairs of support devices. The damping elements are deformed from original flat conditions under forces applied by the support devices, and have concave and convex circular surface adjoining the opposed concave and convex circular surfaces at the support devices.

摘要： An oscillatingly driven machine tool having a housing in which a motor with a motor shaft is received, on which an eccentric element is accommodated, with a spindle head, with a tool spindle that is rotatably mounted about its longitudinal axis in the spindle head, on which a coupling element is non-rotatably received, which cooperates with the eccentric element for generating a movement of the tool spindle which oscillates about its longitudinal axis such that, in addition to the oscillating movement, a differing, superimposed movement is introduced into the coupling element.

摘要： A machine tool that can be guided manually has an outer housing that extends along a longitudinal axis and has a hand grip region. An electrical drive unit and a tool unit are accommodated in the outer housing and are mechanically uncoupled relative to the outer housing. The outer housing has a center of mass that, with respect to the length of the outer housing, is arranged along the longitudinal axis in a section that extends toward the rear from the geometric center of the outer housing.

摘要： Hand-held machine tool having an outer housing extending substantially along a longitudinal axis, with an electric drive unit accommodated in this outer housing, and with a tool arrangement which is disposed at a first end of the electric drive unit. The outer housing of the machine tool has a defined inner contour and the electric drive unit and the tool arrangement have a defined outer contour. The outer contour and the inner contour of the outer housing are at a predetermined minimum spacing from each other. At least one inlet opening for cooling air is disposed in an end region of the outer housing. The electric drive unit drives a fan arrangement which draws in through the at least one inlet opening cooling air which flows substantially parallel to the rotational axis of the electric drive unit through the machine tool and flows out of the outer housing to the outside at the outer contour of the machine tool.
