Abstract
Es un sistema del tipo constituido con una parte inferior fija, que define la estructura portante vinculada al chasis, y una parte superior giratoria, que define la estructura de trabajo donde va montada la pluma, la cuchara cargadora, el motor de accionamiento, la instalación hidráulica que se requiere, la cabina del operario, el contrapeso, etc., estando ambas partes vinculadas entre sí a través de un sistema de engranajes para que la referida parte superior tenga un giro de 360 grados respecto de la parte inferior fija. Dicho sistema de engranajes comprende un aro fijo e inferior (8) fijado al chasis de la maquina, sobre el que se dispone un aro giratorio superior liso, (14) fijado a la estructura de trabajo, donde dicho aro interior (8) se dispone sobre una corona dentada (9) fijada al chasis que constituye el engranaje principal de gran diámetro sobre la que está montada una cadena de transmisión (10) que lleva el movimiento a un engranaje pequeño de tracción (11) que se define en el extremo del eje de salida del motor hidráulico de accionamiento (12). El aro fijo inferior (8), y el engranaje anular externo (9) se fijan al chasis mediante bulones (13), estando dicho engranaje anular externo (9) vinculado a la cadena intermediaria (10) que, en su recorrido, atraviesa también el engranaje pequeño de tracción (11) que se define a la salida del eje del motor hidráulico (12). Entre ambos aros (8) y (14) se intercala un rodamiento anular (16) constituido por una multiplicidad de bolillas, contenidas en cavidades de alojamiento.It is a system of the type constituted with a fixed lower part, which defines the bearing structure linked to the chassis, and a rotating upper part, which defines the work structure where the boom, the loading bucket, the drive motor, the installation are mounted Hydraulics that are required, the operator's cabin, the counterweight, etc., both parts being linked to each other through a gear system so that the said upper part has a 360 degree rotation with respect to the fixed lower part. Said gear system comprises a fixed and lower ring (8) fixed to the machine chassis, on which a smooth upper rotating ring is arranged, (14) fixed to the work structure, where said inner ring (8) is arranged on a toothed crown (9) fixed to the chassis constituting the large diameter main gear on which a transmission chain (10) is mounted that takes the movement to a small traction gear (11) defined at the end of the output shaft of the hydraulic drive motor (12). The lower fixed ring (8), and the outer ring gear (9) are fixed to the chassis by bolts (13), said outer ring gear (9) being linked to the intermediate chain (10) which, in its path, also crosses the small traction gear (11) defined at the output of the hydraulic motor shaft (12). Between both rings (8) and (14) an annular bearing (16) is inserted, consisting of a multiplicity of balls, contained in housing cavities.
