Segmented piston for internal combustion engine

The present invention relates to a multi-piece, in particular at least two-piece, piston (1) for an internal combustion engine having a longitudinal axis (l), comprising a piston outer part (10) having a closed piston head (11), which in the fitted state defines a combustion chamber, and a piston body (13) extending axially away from the piston head (11), and a piston inner part (20), which in the fitted state is connected to a connecting rod. An outer surface (2) radially defining the piston (1) is formed exclusively by at least one portion of the piston body (13) of the piston outer part (10). ... Hirschvogel Umformtechnik Gmbh

Method for transverse rolling

The present invention relates to a cross rolling method having the step of shaping a component blank rotating about a main axis of rotation by means of at least two cross rolling tools located substantially opposite each other with respect to the component blank for the production of a component (1, 2) that is at least partly non-rotationally symmetrical and non-cyclically symmetrical with respect to the main axis of rotation, by moving the cross rolling tools along their main direction of movement. The invention also relates to a cross rolling tool for producing an at least partly non-rotationally symmetrical and non-cyclically symmetrical component (1, 2). ... Hirschvogel Umformtechnik Gmbh

Rotor shaft arrangement and method for manufacturing the same

The present invention relates to a rotor shaft arrangement (1) for a rotor (r) of an electric motor, having a hollow shaft (2) for accommodating a rotor body (k), and a cooling body (3) which is arranged in the hollow shaft (2) and is in thermal contact radially with the hollow shaft (2) and has an axially continuously open structure (s), and therefore a cooling medium in the hollow shaft (2) can flow axially through the cooling body (3). Furthermore, the present invention relates to a rotor (r) with the rotor shaft arrangement (1) according to the invention and also to an electric motor with corresponding rotor (r). ...

Balance shaft

A balance shaft for balancing forces of inertia and/or moments of inertia of a reciprocating-piston internal combustion engine, including: at least one elongate main body; at least one bearing seat, disposed on the elongate main body for the mounting of a radial bearing. In the center point of the bearing seat there is provided the rotational axis of the balance shaft. ... Hirschvogel Umformtechnik Gmbh

Balance shaft

A balance shaft for balancing forces of inertia and/or moments of inertia of a reciprocating-piston internal combustion engine, including: at least one elongate main body; at least one bearing seat disposed on the elongate main body, for the mounting of a radial bearing, wherein in the center point of the bearing seat is provided the rotational axis of the balance shaft. On the elongate main body is provided at least one unbalance portion the center of mass of which lies outside the rotational axis of the balance shaft. ... Hirschvogel Umformtechnik Gmbh

Gearwheel having an axial undercut

A method for producing a gearwheel having an axis of rotation and a tooth system. The teeth have an axial undercut on the tooth flank sides thereof. ... Hirschvogel Umformtechnik Gmbh

Internally pressurized component

An internally pressurized component is provided that includes a main body having at least one cavity; at least one branch having a bore which runs through the branch into the cavity of the main body; at least one separate insert element which is arranged in frictionally locking fashion at least partially in the bore of the branch. The component, at least in that region of the bore at which the separate insert element is arranged, is formed, by way of an autofrettage treatment, as a compacted wall region, and the separate insert element is arranged with an oversize in the bore.. ...
