Abstract:
Die Erfindung betrifft ein Schaltrad (1) für eine Synchronisiervorrichtung eines Zahnräderwechselgetriebes, insbesondere eines Kraftfahrzeugs, wobei ein Kupplungskörper (2) mittels einer das Schaltrad (1) und den Kupplungskörper (2) verbindenden Schweißung (3) am Schaltrad (1) festgelegt ist und wobei sich der Kupplungskörper (2) über eine radiale Höhe (H) von einem radial innenliegenden Endbereich (4) bis zu einem radial außenliegenden Endbereich (5) erstreckt. Um die Qualität der Verzahnung des Kupplungskörpers nach dem Schweißen und Härten zu verbessern, sieht die Erfindung vor, dass die Schweißung (3) vom radial innenliegenden Endbereich (4) beabstandet (a) angeordnet ist.
Abstract:
An assembly of crown wheel (12) and casing (11) of a differential gear assembly (10) is adapted to welding. The casing (11) has a circular flange (17) with an axially extending lip engaged in a circular groove (33) which is further relieved at the radially outer side to give clearance for a high energy welding beam (13). The interface between crown wheel (12) and flange (17) is preferably a frusto-conical surface (70, 65) which presents an oblique angle to said welding beam.
Abstract:
PROBLEM TO BE SOLVED: To produce a double-pinion rack bar having two tooth parts without use of a special processing apparatus for formation of the two rack tooth parts.SOLUTION: A rack production apparatus comprises a clamp mechanism 110 supporting a first rack bar 12A formed with a first tooth part in a hollow shank, a chuck mechanism 140 supporting a second rack bar 12B formed with a second tooth part in a solid shank so that the shaft center line C2 of the second rack bar matches the shaft center line C1 of the first rack bar 12A, a table mechanism 120 causing the chuck mechanism 140 to approach the clamp mechanism 110 and a rotation drive portion 130 rotating the chuck mechanism 140 around the shaft center line C2 relative to the clamp mechanism 110.
Abstract:
A method for manufacturing a driving force transmission device for a vehicle having a case and a ring gear that is fitted to the outer peripheral surface of said case and transmits driving force from a drive source, the method being equipped with: a welding process whereby an annular flange is provided on the case or the ring gear and butt welding is performed by lapping a welding bead along the contact portion of one side surface of the annular flange and the case or the ring gear; a measurement process whereby the exterior shapes of the other side surface of the annular flange adjacent to the one side surface are measured; and an assessment process whereby the quality of the weld is assessed on the basis of the shape of the location corresponding to the lapped portion of the welding bead, of the shapes measured in the measurement process.
