Abstract
The invention relates to a hand-held power tool with a drive shaft embodied in the form of a spindle shaft, which is connected to a tool-clamping device. The drive shaft, which is coupled to a drive motor, cooperates with a torque clutch. The torque clutch is provided with a clutch-adjusting ring that is coupled to a transmission element that cooperates with at least one clutch-adjusting device in order to adjust a torque. The transmission element is situated in an axially and/or radially movable fashion on the outer circumference of a housing component. According to the invention, in at least one position of the clutch-adjusting ring, the transmission element protrudes axially beyond the housing component in the direction toward the tool-clamping device.
Claims23
A hand-held power tool comprising a drive shaft embodied in the form of a spindle shaft which is connected to a tool-clamping device, the drive shaft being coupled to a drive motor and cooperating with a torque clutch, the torque clutch having a clutch-adjusting ring that is coupled to a transmission element cooperating with at least one clutch-adjusting device in order to adjust a torque, the transmission element being situated in an axially and/or radially movable fashion on an outer circumference of a housing component, and in at least one position of the clutch-adjusting ring, the transmission element protrudes axially beyond the housing component in a direction toward the tool-clamping device,
- wherein a cup-shaped protective housing is arranged at the housing component on a face oriented towards the tool-clamping device,
- wherein the tool-clamping device has a plurality of clamping jaws,
- wherein the transmission element encompasses the protective housing and the plurality of clamping jaws radially over at least a subregion of its length.
A hand-held power tool comprising:
- a drive shaft embodied in the form of a spindle shaft which is connected to a tool-clamping device, the tool-clamping device including a plurality of clamping jaws, the drive shaft being coupled to a drive motor and cooperating with a torque clutch, the torque clutch having a clutch-adjusting ring that is coupled to a transmission element cooperating with at least one clutch-adjusting device in order to adjust a torque, the transmission element being situated in an axially and/or radially movable fashion on an outer circumference of a housing component, and in at least one position of the clutch-adjusting ring, the transmission element protrudes axially beyond the housing component in a direction toward the tool-clamping device and partially overlaps axially with the plurality of clamping jaws,
- wherein a cup-shaped protective housing is arranged at the housing component on a face oriented towards the tool-clamping device,
- wherein the transmission element encompasses the protective housing radially over at least a subregion of its length.
A hand-held power tool comprising:
- a drive shaft embodied in the form of a spindle shaft which is connected to a tool-clamping device, the drive shaft being coupled to a drive motor and cooperating with a torque clutch, the torque clutch having a clutch-adjusting ring that is coupled to a transmission element cooperating with at least one clutch-adjusting device in order to adjust a torque, the transmission element being situated in an axially and/or radially movable fashion on an outer circumference of a housing component, a cup-shaped protective housing is arranged at the housing component on a face oriented towards the tool-clamping device, and in at least one position of the clutch-adjusting ring, the transmission element protrudes axially beyond the housing component in a direction toward the tool-clamping device and radially encompasses the protective housing,
- wherein the tool-clamping device has a plurality of clamping jaws,
- wherein the transmission element encompasses the plurality of clamping jaws radially over at least a subregion of its length.
A hand-held power tool comprising:
- a drive shaft embodied in the form of a spindle shaft which is connected to a tool-clamping device, the drive shaft being coupled to a drive motor and cooperating with a torque clutch, the torque clutch having a clutch-adjusting ring that is coupled to a transmission element cooperating with at least one clutch-adjusting device in order to adjust a torque, the transmission element being situated in an axially and/or radially movable fashion on an outer circumference of a housing component, wherein the transmission element has an internal thread that cooperates with an external thread of the housing component, and in an end position of the clutch-adjusting ring, the transmission element protrudes axially beyond the housing component in a direction toward the tool-clamping device such that at least one turn of the internal thread of the transmission element does not cooperate with a turn of the external thread of the housing component,
- wherein a cup-shaped protective housing is arranged at the housing component on a face oriented towards the tool-clamping device,
- wherein the tool-clamping device has a plurality of clamping jaws,
- wherein the transmission element encompasses the protective housing and the plurality of clamping jaws radially over at least a subregion of its length.
