Title (EN) IMPROVEMENTS RELATING TO MULTIPLE DRUM WINCHES
(FR) AMELIORATION RELATIVE A DES TREUILS A TAMBOURS MULTIPLES
Abstract: front page image
(EN)A multiple drum winch is driven by epicyclic differential gearing. One drum (1) rotates with the planet carrier (29, 55) and another drum (2) rotates with the annulus (35, 59) to which it is directly geared, the input being to the sun (27, 53), possibly via reduction gearing (50, 51). The epicyclic can be housed within one of the drums (1). The gear ratios are selectable to achieve a balance between the power requirements of the drums. The drums are journalled only at intermediate zones (22, 23) spanning the centroid of the expected load.
(FR)Un treuil a tambours multiples est entraine par un engrenage differentiel epicycloidal. Un tambour (1) tourne avec le support planetaire (29, 55) et un autre tambour (2) tourne avec le tore (35, 59) sur lequel il s'engrene directement, l'entree s'effectuant sur la partie centrale de l'engrenage (27, 53) eventuellement par l'intermediaire d'un engrenage reducteur (50, 51). L'engrenage epicycloidal peut etre loge a l'interieur de l'un des tambours (1). Les rapports d'engrenage peuvent etre selectionnes pour obtenir un equilibre entre les differentes forces d'entrainement requises par les tambours. Les tambours sont tourillonnes seulement dans des zones intermediaires (22, 23) enjambant le centre de gravite de la charge prevue.
