A power-tool cooling apparatus for a portable power tool includes a first fan configured to generate a first cooling fluid flow to cool a drive unit of the portable power tool, and a second fan that generates a further cooling fluid flow to cool an electronics unit of the portable power-tool. A third fan generates a third cooling fluid flow to cool a second electronics unit of the power-tool, and supplies cooling fluid to the first cooling fluid flow.

Power-tool cooling apparatus

A fastening unit for a radio and/or a sensor module includes at least one of a radio and a sensor module that is configured to connect with an external application unit. The fastening unit is detachably connectable to the at least one of the radio and sensor module.

Fastening unit for a radio and/or sensor module

A hand-held power-tool device includes at least one coupling device, which has at least one contact receiving region, and which is configured to couple an optional additional module to at least one energy supply unit, in at least one operating state. The at least one contact receiving region has (i) at least one receiving opening configured to receive a corresponding contact element of the optional additional module, and (ii) at least one dirt removal opening.

Hand-held power-tool device

An impact mechanism device for a hand power tool comprises at least one impact mechanism including at least one driven cylinder and at least one piston driven in an axial direction by the at least one driven cylinder via a cam mechanism, and at least one planetary gearing configured to drive the at least one driven cylinder and the at least one piston. The at least one piston is positioned at least partially inside the at least one driven cylinder.

Impact mechanism device

A power-tool cooling apparatus for a portable power tool comprises at least one cooling unit configured to generate a cooling fluid flow to cool a drive unit of the portable power tool, and at least one further cooling unit configured to generate a further cooling fluid flow. The at least one further cooling unit is designed to differ from the at least one cooling unit.

The invention relates to a hand-held electric power tool comprising at least one driven rotating part () that is mounted in at least one bearing (). According to the invention, the rotating part () is vibrationally decoupled from the bearing ().

Electric hand-held power tool

A hand-held device (') for contactless distance measurement measures a distance (d) between a target object () and at least one reference point () of the device () using an emitted modulated measurement signal (). The device includes a housing () with a first end () that faces the object () to be measured, and a second end () facing away from the object () to be measured. The housing includes an output unit () for depicting measured results. Several measured distance values are to be assigned to at least one subsection of the path between the object () to be measured and the opposite end () of the housing () via a length-measurement scale () that is displayable in the output unit ().

Device for measuring distance and method for operating said type of device

A motor-driven machine tool () for tools which are to be driven rotationally has, configured as a hand-held machine tool, a pistol-shaped basic shape, in which, lying one behind the other in the stock part () in the direction of the main axis, a motor (), a gear mechanism () and a tool changing magazine () are provided as a structural unit, wherein the tool changing magazine () which is designed, in particular, as a drum magazine is mounted on a neck () of the gear mechanism housing () and is penetrated by the output shaft () of the gear mechanism ().

Motor-driven machine tool

The invention is based on a dust container of a portable power tool for receiving machining residues of a portable power tool (), comprising a container () predetermining a receiving volume (). It is proposed that the container () have a variation means () for varying the size of the receiving volume ().

Dust container of a hand-held power tool

The invention relates to a hand machine tool comprising a first housing shell (), a second housing shell () different from the first housing shell () and being connected to the first housing shell () via a damping element (), and a handle section () arranged on one of the housing shells (). The invention is characterized in that the first housing shell () at least partially encloses the second housing shell ().

Hand-held power tool

An eccentric grinding hand power tool has a housing, a grinding plate unit supported on the housing and being eccentrically driven, an elastic seal that dust-tightly seals the housing with respect to the grinding plate unit, the elastic seal being held on the housing both in a form-locking, positive manner and in a force-transmitting, non positive manner without separate elements but with integrated securing elements.

Eccentric grinding hand power tool

In a power grinder ( ) with a motor ( ) and a gear ( ) that drive an oscillating drive means ( ), which moves a grinding belt ( ) secured to it to reciprocate, a simple change of the grinding belt ( ) is made possible by providing that the grinding belt ( ) has a hook-and-loop closure ( ), or the grinding belt ( ) is disposed with its first end ( ) on the drive means ( ), and its second end ( ) is connected to a handle ( ).

Hand-controlled grinding tool, for machining round objects

A motor-driven manual grinder ( ), in particular an eccentric-plate grinder, has a work spindle ( ) supported in the tool housing ( ) and also has a grinding plate unit ( ) that is driven and rotatable by the work spindle to execute an eccentric motion. The manual grinder ( ) further has an annular first rolling face ( ), extending together with the grinding plate unit ( ) all the way around the eccentric axis ( ), and an annular second rolling face ( ), associated with the first, whose center axis extends coaxially to the central axis ( ) of the work spindle ( ), and on which the first rolling face ( ) can roll. The second rolling face ( ) is supported rotatably about its center axis. It is assigned a braking device ( ), by means of which a rotation of the second rolling face ( ) about its center axis can be selectively prevented for the forced-drive mode or enabled for the free-wheeling mode.

Motor-powered portable grinding machine

An electric hand power tool has a rotatable workshaft, a tool driveable by the rotatable work shaft and performing a movement selected from the group consisting of a rotary movement, a circulatory movement and an oscillating movement, an eccentric pin which is fixedly connected with the work shaft, a tool holder which receives the tool, a rotary bearing through which the tool holder is mounted on the eccentric pin, the eccentric pin and the rotary bearing being formed as an integrated component of the tool holder, and the tool holder being exchangeably coupleable with the work shaft.
