Abstract
An improved motor and bearing assembly is provided for use in an axial gap electric motor. The motor and bearing assembly includes a bearing support, bearing cones circumferentially mounted on the bearing support and a rotating bearing member. Each bearing cone has an axial conical surface at one end. The conical surfaces face each other to form a V-shaped cross-sectional groove. The rotating bearing member includes two rotating bearing rings abutting one another, each ring having an angularly disposed surface forming a V-shaped configuration complementary to the V-shaped groove of the bearing cones. The rotating bearing member provides axial and radial support of the rotor of the axial gap electric motor. Each of the bearing cones is axially movable relative to the bearing support, thereby permitting the stator-to-rotor gap and the bearing clearance to be adjusted after final assembly. Additionally, lubrication and coolant can be introduced to the system through both a lubrication opening in the bearing support and a gap between the bearing cones.
