Title (EN) CANTED WHEELS CARRIER
(FR) TRANSPORTEUR A ROUES INCLINEES
Abstract:
(EN) An object carrier utilizing a pair of canted wheels, both wheels being always engaged with the underlying track to provide a low friction smooth riding non jammable carrier. In one embodiment the wheels are continuously engaged with and drive one another. In another embodiment each wheel is engaged with a separate rolling bearing carried by the carrier wheels axles support block. The canted wheels arrangement causes the carrier to move in a straight line along the direction of pull without crab walking. The carrier (27) includes a carrier block (78) from which divergingly upwardly extend in a common plane a pair of axles (79) which are orthogonal to each other and oriented forty-five degrees to the horizontal and vertical directions. Wheels (81) mounted on the axles (79) engage one another at their upper ends so that as one wheel rotates in a given direction its frictional engagement with the other wheel drives the other wheel in the same direction which prevents twisting or cocking of the carrier (27) within the track. Depending from the carrier block (78) is a stem (83) which carries at its lower end a support chain (85). In a modified carrier, the upper bearing for the carrier wheels (81) is provided by a ballbearing (88) seated in a socket formed in the carrier block (78) proximate to its upper edge. The ball bearings (88) engage the inside surfaces of the wheels (81) and ride within a circular groove (89) formed on the wheels inside surfaces.
(FR) Transporteur d"objets utilisant une paire de roues inclinees, les deux roues cooperant toujours avec le rail support afin d"assurer un fonctionnement sans frottement, exempt d"a-coups et de blocages, du transporteur. Selon un mode d"execution, les roues sont continuellement en prise et s"entrainent mutuellement. Dans un autre mode d"execution, chaque roue est separement solidaire d"un roulement monte sur un axe qui est porte par le bloc support. La disposition des roues inclinees permet au transporteur de se deplacer en ligne droite dans la direction de poussee, sans avancer en crabe. Le transporteur (27) comprend un bloc support (78) portant des axes (79) divergents diriges vers le haut et disposes dans un meme plan, lesdits axes etant orthogonaux et orientes a 45 degres par rapport a l"horizontale et a la verticale. Les roues (81) montees sur les axes (79) sont en prise par leurs bords superieurs de telle sorte que lorsqu"une roue tourne dans un sens donne elle entraine par frottement l"autre roue dans la meme direction, ce qui permet d"eviter les mouvements de torsion et d"oscillation du transporteur (27) dans le rail. Le bloc support (78) est muni d"une tige (83) qui porte a son extremite inferieure une chaine (85). Dans une version modifiee du transporteur, un support superieur des roues (81) est un roulement a billes (88) emboite dans un logement pratique dans le bloc support (78) pres de son bord superieur. Le roulement a billes (88) coopere avec les surfaces internes des roues (81) dans une rainure circulaire (89) pratiquee sur les faces internes des roues.
