  • Self-piloting thrust washers
    Patent number: 5188576
    Abstract: A thrust washer pilots on an end of a planet gear. The piloting relationship is established by an outside diameter surface of the washer and an inside diameter surface of the planet gear. Piloting of the thrust washer on an outside diameter surface of the washer permits the provision of a radial gap between the thrust washer and a shaft on which the gear rotates, facilitating lubricant flow past the washer in an axial direction along the shaft, as well as facilitating assemble of the planet gear and thrust washer to a planet gear carrier.
