  • Patent number: 6969235
    Abstract: An air turbine starter for use in aircraft or other gas turbine engine applications. In a particular embodiment, the air turbine starter has a thrust bearing having an outer ring, an inner ring, a cage and balls. The outer ring has a first shoulder, a second shoulder and a race surface therebetween to receive the balls. The second shoulder is smaller than the first shoulder. The orientation of the cage is such that the pilot of the cage is aligned to the first shoulder of the outer ring. The raceway curvature of the inner ring, the internal clearance, and clearance between the pilot and outer ring are all increased. An improved thrust bearing is also provided.
    Type: Grant

  • Patent number: 6892455
    Abstract: An improved stationary roller shaft of a gear assembly for an air turbine starter is provided. The air turbine starter may be used to start a gas turbine engine, such as may be found in aircraft, ships and military vehicles. The stationary roller shaft is formed of a material having a hardness of at least 66 Rockwell C and having a low inclusion content rating, thereby providing improved wear and/or fatigue properties.
