Un cojinete de chancadora giratoria comprendiendo una superficie del cojinete para soportar el movimiento rotacional de un cabezal chancador, una superficie de montaje para el posicionamiento contra un soporte del cojinete, una pared del cojinete definida entre la superficie de montaje y la superficie del cojinete. al menos una region de la superficie de montaje que en combinacion con la superficie del cojinete define la pared entre el primer extremo del borde y el segundo extremo del borde.

摘要

A gyratory crusher bearing (106) comprising: a bearing surface (110) to support rotational movement of a crushing head (103), wherein a shape profile of the bearing surface (110) at a cross section of the bearing (106) perpendicular to a longitudinal axis (114) of the bearing (106) is substantially circular; a mounting surface (203) for positioning against a bearing support (105), the mounting surface (203) orientated to be outward facing relative to the longitudinal axis (114); a bearing wall (206) defined between the mounting surface (203) and the bearing surface (110), the bearing surface (110) defining a central bore (112) extending between a first edge end (202) and a second edge end (201) of the wall (206); the bearing (106) characterised by: at least one region of the mounting surface (203) that in combination with the bearing surface (110) defines the wall (206) between the first edge end (202) and the second edge end (201) comprises a shape profile at a cross section of the bearing (106) perpendicular to the longitudinal axis (114) that is non-circular to define an anchorage region to inhibit rotation of the bearing (106) about the longitudinal axis (114) relative to the bearing support (105).
