Abstract
A hand-held power tool, in particular an impact driver, an impact drill, or a rotary hammer, is proposed, which has a drive unit and/or output with at least one line of action, which produces at least oscillations along the line of action. In order to reduce these oscillations, the hand-held power tool is equipped with at least one vibration absorber unit. The vibration absorber unit has at least one mobile vibration absorbing element, which has at least one degree of freedom of movement. This degree of freedom of movement encloses at least one angle not equal to zero with the line of action.
Claims15
A hand-held power tool configured to drive a tool, comprising:
- a machine housing defining an interior;
- at least one drive unit disposed in the interior of the machine housing, the at least one drive unit coupled to the tool and configured to drive the tool along a line of action and in a rotary fashion with respect to the line of action, which produces linear oscillations along the line of action and rotary oscillations not parallel to the line of action;
- and
- at least one vibration absorber unit disposed in the interior of the machine housing and defining a vibration absorber unit axis, the vibration absorber unit axis being inclined with respect to the line of action so as to define an angle, the vibration absorber unit being equipped with at least one mobile vibration absorbing element in order to reduce the linear and rotary oscillations, the mobile vibration absorbing element moving along the vibration absorber unit axis.
