  • Planetary helical gear train for a transmission assembly of a washing machine appliance
    Patent number: 11124912
    Abstract: A vertical axis washing machine appliance having a transmission assembly with a planetary helical gear train is provided. The transmission assembly transmits mechanical power from a torque source to an agitation element so that oscillatory motion may be imparted to laundry articles within a wash basket of the washing machine appliance, e.g., during a wash cycle. The transmission assembly includes features that manage axial thrust loads created by helical gears of the gear train. The transmission assembly also includes features that prevent shuttling of the gears and other components of the transmission assembly.
