摘要:
A monolithic, multilayer heating element (26, 126, 226) forms the high temperature tip (22, 122, 222) of a glow plug assembly (20). The heating element (26, 126, 226) includes a conductive core (48, 148, 248) which is surrounded by an insulator layer (50, 150, 250), which in turn supports a resistive layer (52, 152, 252). An optional conductive jacket (172) can surround the resistive layer (152). These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die (54, 64, 164), where it is compressed to fom a so-called green part having dimensional attributes proportional to the finished heating element (26, 126, 256). The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials into an essentially solid mass.

Die Erfindung betrifft eine Vorrichtung zum Ausziehen und Einpressen eines in einer Lagerbohrung eines Lagergehäuses eines Achskörpers aufnehmbaren Radlagers, über welches eine Radnabe im Lagergehäuse drehbar gelagert ist, bestehend aus einer Presseinrichtung sowie einer Pressplatte (65), welche mit einem Stützflansch (84, 85) zwischen der Radnabe und dem Achskörper anordenbar ist, wobei der Achskörper mit mehreren Lageraugen versehen ist, welche zur Montage von weiteren Achsbauteilen oder eines Bremssattels dienen. Um das Austauschen von geschlossenen Radflanschnaben und/oder geschlossenen Radlagern einfach und sicher durchführen zu können, ist erfindungsgemäß vorgesehen, dass die Pressplatte (65) eine Führungsplatte (68) bildet, welche eine etwa halbkreisförmige Aussparung (80) aufweist, welche durch den Stützflansch (84) radial begrenzt ist und, dass die Führungsplatte (68) mit ihrem Stützflansch (84) in einen Zwischenraum zwischen dem Radnabenflansch der Radnabe und dem Lagergehäuse des Achskörpers derart einschiebbar ist, dass sich der Stützflansch (84) beim Ausziehvorgang rückseitig am Radnabenflansch und beim Einpressvorgang am Radlager axial abstützt.
摘要:
The invention relates to a device for raising and withdrawing a bearing unit (3) of a back-up roll (1) of a roll stand. Said bearing unit is comprised of a piece (4) to be inserted inside which has a roll pin bearing arranged therein. According to the invention, a change-over device (16) is configured so that it can be temporarily coupled to the bearing unit (3) and is provided for effecting an axial movement toward and away from the back-up roll (1).
摘要:
In a method of manufacturing a circuit forming board, a first sheet having a first direction is transferred in a second direction, so that the first direction of the first sheet is parallel to the second direction. Films are stuck onto both surfaces of the first sheet while transferring the first sheet in a third direction orthogonal to the first direction of the first sheet. This method allows connecting member, such as conductive paste, to electrically coupling between layers of the circuit forming board.
