A handheld work apparatus includes a motor, a transmission shaft, a tool, a guide tube, a housing, and a first anti-vibration element. The motor via the transmission shaft drives the tool. The transmission shaft is received in the guide tube. The motor is disposed in the housing. The tool is disposed on a front longitudinal end of the guide tube. The housing is disposed on the rear longitudinal end of the guide tube. The housing at least partially encompasses the guide tube, wherein the guide tube projects from the housing. The first anti-vibration element is disposed such that it acts in a vibration-decoupling manner between the housing and the guide tube. The first anti-vibration element is disposed on that side of the motor facing the tool. The handheld work apparatus includes a second anti-vibration element connecting the motor to the housing in an at least indirectly vibration-decoupled manner.

Handheld work apparatus

A blower unit for a portable handheld blower apparatus has a housing section and a tubular receiving space, formed in the housing section, with a first axial end and a second axial end and with a longitudinal center axis. Arranged in the receiving space of the housing section is an axial blower for generating a blower air flow, the axial blower being driven by a drive motor. The receiving space has an intake opening at its first axial end and a discharge opening at its second axial end. In order to reduce operating noise, an air guide plate is arranged at an axial distance in front of the intake opening, the air guide plate having external dimensions that are greater than the external dimensions of the intake opening. An annular gap that supplies intake air is formed between the air guide plate and an outer periphery of the housing section.

Blower unit for a handheld blower apparatus

The invention relates to an electrical work apparatus including an apparatus housing having an electric motor for driving a work tool, a control unit for putting the electric motor into operation, a handle housing having at least one handle for guiding the work apparatus, and a receiving cavity, realized in the handle housing, having an insertion opening for a battery pack for operating the electric motor. For the purpose of decoupling the battery pack in respect of vibration, the handle housing, together with the receiving cavity for the battery pack, is decoupled from the apparatus housing via one and the same antivibration element. A vibration gap is realized between the apparatus housing and the handle housing, wherein the antivibration element at least partly bridges the vibration gap.

Electrical work apparatus having vibration decoupling

A manually guided implement possesses a guide tube, wherein a first mass body is disposed on a first end of the guide tube, and a second mass body is disposed on a second end of the guide tube. One of the mass bodies has a housing, and the other of the mass bodies has a tool driven by a drive motor. A power transmission mechanism for driving the tool between the first and second ends of the guide tube is guided in the interior of the guide tube. A first antivibration element is disposed between the first end of the guide tube and the first mass body. The guide tube in the direction of the longitudinal central axis thereof includes a first rigid sub-portion and a second rigid sub-portion that are connected to one another at an abutment location by at least one second antivibration element.

Manually guided implement

A hedge trimmer has at least one cutting blade and an internal combustion engine operatively connected to the at least one cutting blade so as to drive the at least one cutting blade reciprocatingly. The internal combustion engine has an exhaust gas muffler with an outlet for discharging exhaust gases from the exhaust gas muffler. A multi-part exhaust gas pipe is connected seal-tightly to the outlet of the exhaust gas muffler and connects the outlet of the exhaust gas muffler to an outlet opening where the exhaust gases exit from the hedge trimmer. The multi-part exhaust gas pipe has a plurality of pipe sections, including at least a first pipe section and a second pipe section, wherein the second pipe section is embodied separate from the first pipe section. At least one of the plurality of pipe sections is made of plastic material.

Hedge trimmer

A handheld work apparatus has a motor unit comprising a drive motor. The drive motor drives a tool of the work apparatus, for example a saw chain. The apparatus has a grip unit with a handle that is vibrationally decoupled from the motor unit via an antivibration element. The antivibration element is connected to a first component of the grip unit via a holding device and a second component of the motor unit via a holding element. Arranged in the connection of the first component to the second component through the antivibration element is a predetermined breaking point formed in a third component that is replaceable independently of the first component and the second component. The strength of the connection of the first component to the second component through the antivibration element is lowest at this predetermined breaking point.

A hand-held work implement comprises a housing, at least one tool and a combustion engine for driving the tool. The combustion engine has a cylinder and has a piston which drives a crankshaft in rotation about an axis of rotation. The crankshaft drives a fan impeller. The work implement has a handle unit with a handle bar and has an engine unit, these being connected to one another via anti-vibration elements. The combustion engine has a transverse plane which encompasses the cylinder longitudinal axis and which runs parallel to the axis of rotation of the crankshaft. The transverse plane divides the work implement into a front region, in which a section of the tool that projects out of the housing is arranged, and a rear region. The fixing of the anti-vibration element to the cylinder is realized in the front region.

Hand-held work implement

A handheld work apparatus has a drive motor () that is held in a motor housing (). At least one handle () is provided, with a vibration gap () being formed between the handle () and the motor housing (). The vibration gap () permits a relative movement between handle () and motor housing (). The handle () is connected to the motor housing () via at least one anti-vibration device () that bridges the vibration gap (). The anti-vibration device () has a longitudinal center axis (). The anti-vibration device () bridges the vibration gap () via at least one tension element. The anti-vibration device () also has a spring () arranged functionally in series with the tension element.

The invention relates to a portable work apparatus having a housing and a work tool which is driven by an electric motor via a gear assembly. A flywheel which rotates about a rotational axis is arranged in the drive train between the electric motor and the gear assembly, which flywheel is connected fixedly to an output shaft so as to rotate with it, which output shaft protrudes into a gear assembly space and has a drive pinion. The output, shaft and the flywheel are mounted in the housing by two bearing locations, the rotational axis of the flywheel and a motor shaft of the electric motor lying coaxially with respect to one another, and the motor shaft of the electric motor being connected fixedly to the flywheel so as to rotate with it. The electric motor is fixed in the housing exclusively via a torque support.
