Title
(EN) TRACK CARRIER ROLLER WITH RESILIENT AND REPLACEABLE TREAD
(FR) ROULEAU PORTEUR DE CHENILLE A BANDE DE ROULEMENT SOUPLE ET REMPLAÇABLE
Abstract
(EN)
A track roller assembly (10) supports and guides a portion of the endless track (12) of a track type vehicle (14) as that portion of the track (12) travels between a drive wheel (11) and an idler wheel (13) of the vehicle (14). The rim portions (28, 30) of the roller assembly (10) include a plurality of alternating resilient non-metallic rings (18) and metallic rings (20). The non-metallic rings (18) are compressed between the metallic rings (20) to increase the diameter of the outer walls (44) of the rings (18). The link rails (82, 84) contact the non-metallic rings (18) only. Conventional track supporting rollers have metallic treads which generate noise and impact against the metal link rails. The rollers often fail to rotate due to insufficient friction with the link rails. The subject roller assembly (10), with resilient rings (18) in contact with the link rails (82, 84), generates low levels of noise and vibration and produces sufficient friction to rotate the rollers (10).
(FR)
Un ensemble à rouleau (10) de chenille supporte et guide une partie de la chenille (12) sans fin d'un véhicule (14) à chenilles, à mesure que cette partie de la chenille (12) se déplace entre une roue d'entraînement (11) et une roue libre (13) du véhicule (14). Les parties de rebord (28, 30) de l'ensemble (10) à rouleau comprennent une pluralité d'anneaux non métalliques (18) et d'anneaux métalliques (20) alternant. Les anneaux non métalliques (18) sont comprimés entre les anneaux métalliques (20) afin d'augmenter le diamètre des parois extérieures (44) des anneaux (18). Les rails de liaison (82, 84) viennent uniquement au contact des anneaux non métalliques (18). Des rouleaux de support de chenilles classiques ont des bandes de roulement métalliques créant du bruit et un impact contre les rails de liaison en métal. Souvent les rouleaux ne peuvent pas tourner du fait d'un frottement insuffisant avec les rails de liaison. L'ensemble à rouleau (10) de l'invention, comportant des anneaux souples (18) en contact avec les rails de liaison (82, 84), crée de faibles niveaux de bruit et de vibratiions et produit suffisamment de frottement pour faire tourner les rouleaux (10).
