Title (EN) ARRANGEMENT FOR ROTATOR UNITS
(FR) DISPOSITIF POUR BLOC ROTATIF
Abstract: front page image
(EN)Arrangement for rotator units, especially those which are intended for rotation of excavator buckets. It comprises a motor (27) which, together with a transmission (26, 29) which is coupled to a drive wheel (24) in the chain transmission, is arranged in a bearing element (16), which is suspended in the housing (6) in a pivotable manner, but free from fixed connections to the housing. In the transmission there is a drive wheel (24) for a chain transmission, which wheel is connected by means of a drive chain (25) to a driven chain wheel (13) included in a shaft system (12) mounted in the housing. Spring elements (30) are arranged to pivot the bearing element (16) in such a way that the chain is held tensioned. The suspension of the bearing element in the housing is designed in such a way that deformations of the housing resulting from external force effect are not transmitted to the bearing element in a way that would deform the latter.
(FR)Dispositif pour bloc rotatif, notamment pour les godets d'excavatrices, comprenant un moteur (27) qui, de même qu'une transmission(26, 29) couplée à une roue motrice (24) dans la transmission par chaîne, est placé dans un élément de support (16) qui est maintenu en suspension dans le logement (6) de manière à pouvoir pivoter, mais non pas solidarisé, par des connections fixes. La transmission comporte une zone motrice (24), pour effectuer une transmission par chaîne, qui est reliée, au moyen d'une chaîne de transmission (25), à une roue de transmission (13) se trouvant sur un arbre de transmission (12) monté dans le logement. Des éléments de ressort (30) font pivoter l'élément de support (16) de sorte que la chaîne est constamment tendue. La suspension de l'élément de support dans le logement due à des forces externes ne peuvent conduire à des déformations de l'élément de support.
