Description
- The present invention is directed to a hand-held power tool according to the definition of the species in Claim 1.
- Hand-held power tools designed as rotary hammers and/or chisel hammers with a motor unit and a transmission unit, and with a working axis serving as a drilling axis and/or impact axis are known. The transmission unit has rotation axes that are oriented either perpendicular or parallel to the working axis.
- The present invention is directed to a hand-held power tool, in particular a rotary hammer and/or chisel hammer, with a motor unit and a transmission unit, and with a working axis.
- It is provided that at least one transmission element of the transmission unit includes a rotation axis that is oriented diagonally to the working axis. A “transmission unit” refers, in particular, to a unit for transferring and/or converting rotary motions. A “working axis” refers, in particular, to a rotation axis of a tool fitting or a tool that is installable in the tool fitting, and/or an impact axis, in the direction of which an impulse on the tool—which is installable in the tool fitting—may be introduced. Furthermore, “oriented diagonally” means, in particular, that the rotation axis is oriented neither parallel nor perpendicular to the working axis, and preferably forms an angle between 95° and 175° or between 5° and 85°, and, particularly preferably, between 100° and 150° or between 10° and 60° with the working axis. With a design of this type, a very compact design may be attained and, in particular, the overall length may be reduced, in particular when the rotation axis of the transmission element includes at least one component that extends in the direction of the working axis.
- The transmission element may be provided in the form of various elements that appear reasonable to one skilled in the art, e.g., bearing axes, pulleys, etc., and particularly advantageously, they may be provided at least partially in the form of a gearwheel and/or a shaft, by way of which a compact design and an advantageous power flow may be attained. When the transmission element is provided in the form of a motor shaft—which should also be regarded as the transmission element in the sense of the present invention—the motor unit in particular may be integrated in a hand-held power tool housing in a particularly space-saving manner. Furthermore, the position of a center of mass of the motor unit may be advantageously tailored to basic conditions. A “motor shaft” refers, in particular, to a shaft that is driveable directly using a turbine unit and/or an electromagnetic unit of the motor unit.
- Furthermore, installation space may be spared when the transmission element is provided in the form of a gear stage. A “gear stage” refers, in particular, to a unit that includes different input and output radii. Torque is introduced into the gear stage via by the input radius, and torque is transmitted to a corresponding component via the output radius.
- The inventive means of attaining the object of the present invention is basically suited for use with all hand-held power tools that appear reasonable to one skilled in the art, and particularly advantageously for hand-held power tools with an impact mechanism, so that a particularly compact design may be attained despite the need to provide additional components for the impact mechanism.
- The impact mechanism may include various drive units for converting a rotary motion into an impact motion, such as an eccentric unit or, advantageously, a wobble bearing, which may also be integrated in a particularly space-saving manner. A “wobble bearing” refers, in particular, to a bearing with which, due to a wobble element supported obliquely in a bearing means, a wobbling motion of the wobble element results when the bearing element rotates.
- In a further embodiment of the present invention it is provided that the hand-held power tool includes a motor shaft with an output region that is located at least partially on a side of the working axis facing away from a center of mass of the motor unit, by way of which an overall height, in particular, which is defined by other components, may be used advantageously for the motor unit and the motor shaft, and, in all, a minimal overall height may be attained. The same applies when the hand-held power tool includes a motor shaft with an output region that is located at least partially on a side of the working axis facing away from a center of mass of the motor unit.
- Further advantages result from the description of the drawing, below. Exemplary embodiments of the present invention are shown in the drawing. The drawing, the description and the claims contain numerous features in combination. One skilled in the art will also advantageously consider the features individually and combine them to form further reasonable combinations.
