Abstract
A railcar adapter for radially connecting a railcar body to a bearing. The railcar adapter provides an adapter body, and a top cover mounted onto an outer surface of the adapter body. The top cover is includes at least one recess receiving a radially outwardly projecting pin provided to the outer surface of adapter body. The top cover is adapted to be in direct radial contact with the railcar body.
Claims19
A railcar adapter for radially connecting a railcar body to a bearing, and comprising an adapter body having:
- two lateral channels each delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, the lateral channels being adapted to cooperate with the railcar body,
- two frontal surfaces,
- an inner surface acting as a bearing seat for the bearing, and
- an outer surface, wherein
- the railcar adapter also comprises two frontal flanges that inwardly protrude with respect to the inner surface, and that delimit with the inner surface a housing for the bearing, wherein
- the railcar adapter is further provided with a top cover mounted onto the outer surface of adapter body, the top cover being adapted to be in direct radial contact with the railcar body, the top cover defining a recess therein, and wherein
- a radially outwardly projecting pin located on the outer surface of the adapter body, the radially outwardly projecting pin defining a slot therein which extends, at least partially in a radial direction along an outer lateral surface of the radially outwardly projecting pin, the radially outwardly projecting pin being configured to be located in and engage the recess in the top cover,
- a lateral pin located on the top cover within the recess and configured for insertion into the slot.

A railcar adapter assembly comprising:
- a railcar adapter,
- a bearing mounted inside the railcar adapter,
- a backing ring adapted to come into axial contact with the bearing at a first side thereof, and an end cap assembly adapted to come into axial contact with the bearing at another side thereof, opposite to the first side, the railcar adapter comprising an adapter body having:
- two lateral channels each delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, the lateral channels being adapted to cooperate with the railcar body,
- two frontal surfaces,
- an inner surface acting as a bearing seal for the bearing, and
- an outer surface, wherein
- the railcar adapter also comprises two frontal flanges that inwardly protrude with respect to the inner surface, and that delimit with the inner surface a housing for the bearing, wherein
- the railcar adapter is further provided with a top cover mounted onto the outer surface of the adapter body, the top cover being adapted to be in direct radial contact with the railcar body, the top cover having a recess which is bounded by a recess sidewall, the top cover further defining a slot in the recess sidewall and wherein
- a lateral pin is located on the radially outwardly projecting pin of the adapter body, the lateral pin is configured to engage the slot in the top cover when the radially outwardly extending pin is inserted in the recess of the top cover.
