Embodiment Construction

[0036] figure 1 A schematic side view of a first embodiment of a device 100 for reducing and / or compensating vibrations according to the invention is shown. The device 100 includes a movably mounted balancing body 102 and a drive mechanism 104 . The drive mechanism 104 acts on the compensating body 102 in such a way that it can be driven, preferably reciprocated, by the drive mechanism 104 . In a preferred embodiment, the compensating body is geometrically simple, for example substantially cylindrical or cuboid.

[0037] In the present example, the drive mechanism 104 is designed as an oscillating disk drive 106 . The pivot disk drive 106 has a pivot disk 112 which is arranged via a pivot bearing 108 on a rotatably driven drive shaft 110 and can be driven via this drive shaft 110 . A swing finger 114 is arranged on the swing plate 112 . The drive shaft 110 extends here along an axis of rotation 116 , about which the drive shaft is rotatably driven. The swivel bearing 108 in...

Abstract

The invention relates to a vibration reduction and / or compensation device, particularly for a handheld machine tool, the device includes at least one movably supported balance body (102) and a driving mechanism (104) acting on the balance body (102, and the at least one balance body (102) can be driven by the driving mechanism. The invention proposes that at least one added mass (140), which can move relative to the balance body (102), preferably move relatively under limitation, is arranged on and / or in the balance body (102).

Description

technical field [0001] The invention relates to a device for reducing and / or compensating vibrations. Background technique [0002] A device for reducing and / or compensating vibrations, in particular for hand-held power tools, is known from the as yet unpublished patent application DE 102008000677. “Reducing and / or compensating for vibrations” is to be understood here in particular as measures and / or means and / or effects thereof which, in particular, counteract vibrations occurring in the hand-held power tool which are caused by internal and / or external forces. Known from DE 102008000677 is a hand-held power tool, in particular a hammer drill and / or chisel, which has a reciprocating impact drive for an impact-drivable tool, in particular an insert tool, in which A balancing body drivable, in particular reciprocating, by the stroke generating device as drive mechanism. [0003] In the example of DE 102008000677, the percussion drive has at least one reciprocating element dr...
