Abstract

Un rodillo de oruga (300) incluye un cuerpo (302) que tiene una configuracion anular que define un eje de rotacion (304), una direccion radial (308), y una direccion circunferencial (306) dispuesta alrededor del eje de rotacion (304). El cuerpo (302) tambien define un orificio pasante (316) que se extiende axialmente a traves del cuerpo (302) que se centra en el eje de rotacion (304). Un vacio ciego (318) se dispone anularmente alrededor del eje de rotacion (304), el vacio ciego (318) se separa radialmente del orificio pasante (316) una distancia minima predeterminada (332), que forma una porcion en voladizo (320) que define un punto flexible (326) y una distancia radial flexible (328) medida radialmente desde el punto flexible (326) hasta el orificio pasante (316).
