摘要： The invention is directed to a cutter blade support for a pair of knives of a hedge trimmer. The cutter blade support includes first and second bars conjointly defining a space therebetween. First and second cutter blades are arranged in the space and define respective sets of apertures formed therein. The first bar has openings formed therein and a plurality of threaded bolts are held in the second bar. The threaded bolts extend through the respective sets of apertures and have respective end portions extending through the openings in the first bar. Attachment nuts are disposed on the first bar and threadably engage corresponding ones of the end portions. The threaded bolts are pressed into the second bar so as to be tightly held therein and so as to be nonrotatable with respect thereto.

摘要： A chain saw includes a guide bar (1) for a saw chain, a housing (3), a sprocket wheel cover (4), and at least one stud (5) fixed on the housing (3) for threadably fastening the sprocket wheel cover (4) and the guide bar (1). The free thread end (7) of the stud (5) has a maximum usable screw-in depth (tmax) for a nut (6) to be screwed thereon. A stop (9) for the sprocket wheel cover (4) having a stop surface (10) as well as a support surface (11) for contact engaging the stop surface (10) are provided. In the mounted state of the guide bar (1), a distance (a) remains between the stop surface (10) and the support surface (11). The support surface (11) contact engages the stop surface (10) of the stop (9) when the guide bar (1) is removed and the nut (6) is tightened and the nut (6) is screwed onto the studs (5) with a stop screw-in depth. The stop (9) is configured in such a manner that the maximum usable screw-in depth (tmax) is greater than the stop screw-in depth.

摘要： The invention relates to a motor-driven chain saw having a motor mounted in a housing for driving a saw chain on a guide bar. The guide bar extends forwardly in the longitudinal direction of the chain saw from a forward housing end face. The housing is held by a grab handle for holding and guiding the chain saw. The handle has an upper segment projecting over the housing transversely to the longitudinal center axis of the guide bar. The upper segment extends at one end with a transition segment into a lateral segment lying approximately parallel to the plane of the guide bar and next to the housing. The cross section of the upper segment and the cross section of the lateral segment are configured in a shape which departs from the circular shape and are approximately the same. This affords an ergonomically advantageous hold and increases the operational safety. The major cross-sectional axis of the lateral segment lies approximately perpendicularly to the plane of the guide bar and the same cross-sectional axis in the upper segment lies at an angle of less than 90.degree. to a reference plane which extends at right angles in the longitudinal center axis of the guide bar at right angles to the plane of the guide bar.

摘要： The invention relates to a connection of a crankcase (3) of an internal combustion engine (1) to a cylinder housing (2) of which at least one housing part is made of light metal. The housing parts (2, 3) lie with their respective housing flanges (4, 5) in surface contact one against the other and are clamped seal-tight to each other with the aid of retaining screws (7). The retaining screws (7) are of light metal and a curing liquid seal (18) is between the housing flanges (4, 5) so as to lie against both sides. In this way, a connection for a light metal cylinder housing (2) with a crankcase (3) is achieved by using light metal housing materials. A reliable seal is provided which is permanently resistant to the operating loads of the engine (1).

摘要： A portable handheld work apparatus has an internal combustion engine (5) having a cylinder (8) and a crankcase (13). The cylinder (8) has an opening (19) for exhaust gases whereat an exhaust-gas muffler (14) is mounted. The exhaust-gas muffler (14) is mounted on the cylinder (8) at least at one attachment location (40, 41) and at least a further attachment location (42) on the internal combustion engine (5). A reduced weight of the work apparatus and a low mechanical load of the exhaust-gas muffler (14) can be achieved when the exhaust-gas muffler is fixed at at least one of the attachment locations (42) via a connection which permits a limited relative movement between the exhaust-gas muffler (14) and the internal combustion engine (5) in at least one direction.

摘要： A chain saw includes a guide bar for a saw chain, a housing, a sprocket wheel cover, and a stud fixed on the housing for threadably fastening the sprocket wheel cover and the guide bar. The free thread end of the stud has a maximum usable screw-in depth (tmax) for a nut. A stop for the sprocket wheel cover having a stop surface as well as a support surface for contact engaging the stop surface are provided. In the mounted state of the guide bar, a distance (a) remains between the stop surface and the support surface. The support surface contact engages the stop surface when the guide bar is removed and the nut is tightened and screwed onto the studs to a stop screw-in depth. The stop is configured in such a manner that the maximum usable screw-in depth (tmax) is greater than the stop screw-in depth.
