A tire support rim for track roller associated with a flange is provided with a circular tire (), and a support rim () for an annular track roller producing a flange. The rim () defines a peripheral edge intended to bear a tire, a medial edge in contact with the medial portion of the roller, and two opposite faces producing, on the one hand, an open face and, on the other hand, a bearing face positioned against the surface of the flange of the roller. The rim () incorporates a cooling device having at least one circulation duct for air passing through the thickness of the rim from an orifice () of the open face such that the duct has a portion at the medial edge and a portion positioned radially on the bearing face between the medial and peripheral edges.

Tire support rim for track roller associated with a flange

A device for monitoring wear of a flange () of a roller () includes a peripheral rim () and intended to cooperate with a homologous flange () of a roller () positioned face-to-face to interact with the head of a rolling rail (). The device includes at least one first recess localized at the level of a peripheral line of constant radius on the flange () configured to be positioned at the level at which the point () of separation of the flange () relative to its homologue () is the smallest.
