Title
(EN) SPALLING RESISTANT TRACK LINK AND ROLLER INTERFACE
(FR) INTERFACE DE ROULEAU ET DE LIAISON DE VOIE RÉSISTANTE À L'ÉCAILLAGE
Abstract
(EN)
A track link rail surface and roller interface (400) includes a first roller (402) including a cylindrical configuration defining a radial direction (R), a longitudinal axis (A), a circumferential direction (C), and a plane (RA) containing the radial direction (R) and the longitudinal axis (A). The first roller (402) includes a first track link rail engaging surface (404) including a first concave arcuate surface (406) defining a first concave radius of curvature (408). The interface (400) includes a first track link (410) including a first track link rail surface (412) including a first convex arcuate surface (414) defining a first convex radius of curvature (416) that is less or equal to the first concave radius of curvature (408).

L'invention concerne une interface de rouleau et de surface de rail de liaison de voie (400) comprenant un premier rouleau (402) comprenant une configuration cylindrique définissant une direction radiale (R), un axe longitudinal (A), une direction circonférentielle (C) et un plan (RA) contenant la direction radiale (R) et l'axe longitudinal (A). Le premier rouleau (402) comprend une première surface de mise en prise de rail de liaison de voie (404) comprenant une première surface arquée concave (406) définissant un premier rayon de courbure concave (408). L'interface (400) comprend une première liaison de voie (410) comprenant une première surface de rail de liaison de voie (412) comprenant une première surface arquée convexe (414) définissant un premier rayon de courbure convexe (416) qui est inférieur ou égal au premier rayon de courbure concave (408).
