The present disclosure relates to a method for connecting a motor to a gearbox, wherein, first, a form- and/or force-fit connection between the motor and the gearbox is established by screwing together a motor- or gearbox-side first component and the respective motor- or gearbox-side second component to be connected thereto, or by establishing an interference fit between these two components, and wherein, additionally, an axial lock between the two components is then established by means of caulking, in that a lug formed on the first component is deformed by means of a caulking tool into a recess formed on the second component.

A cutting tool and a method of operating a cutting jaw is provided. The cutting tool includes a first jaw member having a first cutting edge and a first relief area adjacent the first cutting edge, the first jaw member further having a first projection extending from the first cutting edge into the first relief area. A second jaw member has a second cutting edge and a second relief area adjacent the second cutting edge, the second jaw member further having a second projection extending from the second cutting edge into the second relief area. Wherein the first projection and the second projection are sized to engage a leg of an ear clamp and prevent fully closing the ear clamp when the cutting tool is used in a crimping operation.

A vehicle component such as an axle spindle or suspension beam (3) is connected to a tubular vehicle axle (1) by fitting a connector sleeve (2) onto the axle and subjecting the assembly to a crimping operation in which plural depressions (206,2018) are formed by indentation in the connector sleeve and the axle wall at the connection region (11,12) to fix the connector sleeve on the tubular axle. In the described proposals a solid lubricant (4) such as molybdenum disulphide is applied at the connection region between the connector sleeve (2) and axle (1), before crimping. The further vehicle component (3) is then connected to the connector sleeve (2) by welding.

A sound attenuator has an inner pipe (12) with expansion sections (121) of enlarged diameter corresponding to the constriction sections (141) of an outer pipe (14). The expansion sections (121) in pairs axially delimit an intermediate inner pipe section (122) containing a wall opening (18) and having a reduced diameter relative to the expansion sections (121). The inner surface of the outer pipe (14) in each of its constriction sections (141) is connected to the outer surface of the inner pipe (12) in its respective corresponding expansion section (121). A method of manufacturing such a sound attenuator (10) also is provided and uses internal high-pressure forming.

In a flare fitting structure in which a flared portion that is formed in an end of a flared tube and faces a connected member is pressed by a flared nut to connect the flared tube to the connected member, the flared tube is formed by flaring a cylindrical tube including an original tube and a coating layer that coats a surface of the original tube, the flared portion includes a flare inclined plane that faces the connected member, and the flare inclined plane is formed with a machining portion in which the original tube is exposed by a machining operation.

A method for producing a cutting section from a closed tubular element (14) which is in the form of a hollow cylinder and from one or more drill segments (16) which are connected to the closed tubular element (14).

A crimping method including providing a coupling including a sidewall and a ribbed stem having a plurality of radial valleys, the ribbed stem defining a longitudinal axis, wherein the first sidewall extends radially to the axis, and providing a die including a stop and a channel extending through the stop, the channel having a ribbed section with a plurality of ribs. The ribbed stem is inserted through the first stop, into the first channel and into the end of a hose. With a ferrule arranged between the ribbed section and the hose and the sidewall pressed against the stop, the die is used to compress the end of the hose between the ferrule and the ribbed stem with the plurality of radial valleys radially aligned with the plurality of ribs. The couplings are selected from a medical gas medical gas outlet rough-in and a medical gas nut nipple.
