Definitions
- the present invention relates to a machine tool with at least one accumulator as an energy source and at least one motor.
- the machine tool is characterized in particular in that the motor is arranged essentially longitudinally to a cutting axis S of the machine tool and is arranged essentially on a first side of the cutting axis S, while the at least one accumulator is arranged essentially on a second side of the cutting axis S.
- a particularly well-balanced machine tool can be provided by this arrangement of motor and accumulator.
- the motor in the longitudinal direction of the machine tool, a positive drive for the tool of the machine tool can be made possible in a simple manner.
- Cut-off grinders or angle grinders are known in the field of machine tools, with which cuts can be made in a substrate to be processed or which can be used to process the surface of a substrate.
- Such cutting or angle grinders usually have a disc-shaped tool that is referred to as a cutting or grinding wheel.
- accumulators Due to the increase in the available capacities in the area of accumulators ("accumulators"), more and more battery or accumulator-operated cut-off machines are being introduced onto the market; This is particularly the case for applications in which petrol cut-off grinders were previously used.
- the motor is arranged transversely to the cutting direction or transversely to the cutting axis.
- Such machine tools usually have a belt drive, with belt drives enabling good transmission of the rotational movement of the motor to the tool of the machine tool. This is particularly so because the torque to be transmitted from the engine is smaller than the torque that can be transmitted by the belt of the belt drive.
- arranging the motor transversely to the cutting axis of the machine tool can make it more difficult to brake the machine tool, since the high braking torque may not be able to be transmitted sufficiently to stop the tool of the machine tool sufficiently quickly.
- the object on which the present invention is based is to overcome the above-described deficiencies and disadvantages of the prior art and to provide a machine tool that is handy and compact, so that the machine tool can be used well, even over long periods of time times.
- experts would welcome it if the braking of the machine tool could be improved and made safer.
- the structure of the machine tool and the arrangement of the components within the machine tool should be as simple, compact and robust as possible, and the machine tool should have good ergonomics.
- a machine tool is provided with at least one accumulator as the energy source.
- the machine tool also has a motor.
- the machine tool is characterized in particular in that the motor is arranged essentially longitudinally to a cutting axis S of the machine tool and is arranged essentially on a first side of the cutting axis S, while the at least one accumulator is arranged essentially on a second side of the cutting axis S.
- a belt drive can be dispensed with. Rather, a positive drive of the tool of the machine tool can be made possible.
- high braking torques can advantageously be transmitted quickly enough to stop the tool of the machine tool quickly enough and to reliably avoid injuries to the user of the machine tool. It has been shown that the braking of the tool can also be ensured particularly quickly with the invention when the tool rotates at high speeds in combination with short transmission times.
- the motor and the at least one accumulator are on different, generally opposite sides of the cutting axis of the machine tool are available.
- the motor of the machine tool can be on one side of the cutting axis, while the accumulator is on the other side of the cutting axis.
- the machine tool has two or more accumulators, it is preferred within the meaning of the invention that all the batteries are essentially on one side of the cutting axis of the machine tool, while the motor is arranged essentially on the other side of the cutting axis.
- the side of the machine tool on which the motor is arranged can be referred to as the "motor side” of the machine tool within the meaning of the invention, while the other side of the machine tool on which the at least one rechargeable battery is arranged is referred to as the "accumulator or battery side”. can be.
- the wording “essentially” can also preferably mean that a small part of the volume of the object, such as a battery or motor, can protrude beyond the cutting axis, with the larger part of the volume of the battery or motor remaining on the battery or engine side of the machine tool is arranged.
- the term "motor axis" is preferably to be understood as the axis of rotation of the moving parts of the motor of the machine tool.
- the moving parts of the motor can in particular be the rotor of the motor, which is preferably designed as an electric motor.
- the wording according to which the motor of the machine tool is arranged essentially longitudinally to its cutting axis S means, in the context of the invention, in particular that the motor is not arranged transversely to the cutting axis, as is customary in the prior art.
- the object of the invention is thus distinguished from the prior art due to the arrangement of the motor in the longitudinal direction of the machine tool.
- a central axis through the engine of the machine tool is substantially parallel to the cutting axis of the machine tool.

- the transmission of the machine tool is not designed as a belt drive, but rather in a form-fitting manner.
- the belt drive By avoiding or omitting the belt drive, an occurrence of undesired slippage can be prevented and particularly trouble-free and robust operation of the machine tool can advantageously be ensured.
- devices and methods can be implemented particularly well in the machine tool, which enable protection against kickback events.
- a kickback brake can be provided on the machine tool, with the kickback brake being designed to brake the tool of the machine tool or to switch off the machine tool as a whole when a kickback event is detected.
