Abstract

  • 2.1 Bei der automatisierten Großserienmontage von Motoren ist ein erheblicher Aufwand zur Montage der Einzelteile für die Ventilbetätigung sowie der Ventilschaftabdichtung notwendig. Für jedes Einzelteil ist ein eigener Handhabungsautomat notwendig. Durch die neue Montagevorrichtung können die Ventilbetätigungsteile zusammen mit der Ventilschaftabdichtung montiert werden. 2.1 In the case of automated large-scale assembly of engines a considerable effort for the assembly of the individual parts for the valve actuation and the valve stem seal necessary. There is a separate one for each individual part Handling machine necessary. With the new one Mounting device can the valve actuation parts can be installed together with the valve stem seal.
  • 2.2 Durch eine unmittelbare oder mittelbare lösbare Verbindung zwischen Ventilschaftabdichtung (5) und Ventilfederteller (2) werden die Montagekosten der Ventilbetätigungsteile reduziert sowie die Montage der Ventilschaftabdichtung (5) erleichtert. 2.2 By a direct or indirect solvable Connection between valve stem seal (5) and Valve spring plate (2) are the assembly costs of the Valve actuation parts reduced and the assembly of the Valve stem seal (5) relieved.
  • 2.3 Die Vorrichtung eignet sich zur maschinellen Montage von Ventilschaftabdichtungen insbesondere bei Großserien. 2.3 The device is suitable for the mechanical assembly of Valve stem seals, especially for large series.
