Abstract
Methods and apparatus to passively lubricate a worm gear assembly are disclosed herein. An example worm gear assembly includes a housing defining an internal cavity, a worm gear in the internal cavity of the housing, and a worm wheel in the internal cavity of the housing. The worm wheel is meshed with the worm gear. The worm wheel includes a first side surface, a second side surface opposite the first side surface, a peripheral edge with a plurality of teeth between the first side surface and the second side surface, and a vane on the first side surface. The vane extends radially between a center of the first side surface and the peripheral edge. The vane is to move lubricant from a bottom of the housing to the worm gear to lubricate an interface between the worm gear and the worm wheel.
