Abstract
A bearing assembly is provided having a roller bearing with an inner raceway fitted around the journal portion of an axle. An outer raceway combines with the inner raceway to receive roller elements. An improved lubricant seal arrangement is provided between the wear ring and the supporting outer raceway comprising a stator element, a rotor element and a flinger element.
Claims18
A roller bearing assembly comprising:
- a generally cylindrical cone having a generally cylindrical, outwardly directed raceway thereon,
- a generally cylindrical cup having a generally cylindrical, inwardly directed raceway thereon,
- the cone having a generally flat, axially inward face,
- the cup having a radially inward facing cylindrical counterbore,
- a generally cylindrical wear ring adjacent and axially inward from the generally flat, axially inward face of the cone,
- the wear ring having a generally cylindrical outer surface
- the seal having a first end section, an intermediate section and a second end section,
- the first end section received in the radially inward facing cylindrical counterbore of the cup,
- a seal of generally cylindrical configuration,
- a rotor element of a generally cylindrical configuration, the rotor element comprising a base section, a radially outer section, a radially intermediate section and a radially inner section,
- the radially inner section of the rotor element having an outer surface of the rotor element having outer surface parallel to the generally cylindrical outer surface of the wear ring,
- a stator element of a generally cylindrical configuration, the stator element comprising a base section, a radially outer section, a radially intermediate section, and a radially inner section,
- the radially outer section of the stator element having an outer surface adjacent the radially intermediate section of the seal,
- the radially outer section of the stator extending between the seal intermediate section and the radially outer section of the rotor element,
- the radially intermediate section of the stator element extending between the radially outer section of the rotor element and the radially intermediate section of the rotor element,
- at least a portion of the radially inner section of the stator element extending between the radially intermediate section of the rotor element and the radially inner section of the rotor element,
- and a flinger element of a generally cylindrical configuration having a base section extending between the generally cylindrical surface of the wear ring and the radially inner section of the rotor element.
