  • Patent number: 10305344
    Abstract: A drive device includes a shaft rotatably supported by a first bearing and a second bearing. The first bearing is disposed in a shaft hole of an output frame end. The second bearing is disposed in a bearing box of an opposite-to-output frame end. An oil seal is fixed in the shaft hole and is closer to an output end than the first bearing is, and is in sliding contact with an outer circumference of the shaft. A biasing member is housed in the bearing box and biases an outer race of the second bearing toward the output end. Accordingly, a deflection amount and a bend amount of the shaft at the location where the oil seal is disposed may be reduced.

  • Patent number: 9819235
    Abstract: A rotor core has a regular decagon base portion in its cross section relative to a shaft center and ten convex portions each of which is located between each angle of the regular decagon base portion. Each convex portion has a first convex curve having a single curvature radius. Each permanent magnet is a curved plate and has a concave curve and a second convex curve. Each permanent magnet is provided so that the concave curve adheres on the first convex curve. When each permanent magnet moves in circumferential direction relative to the rotor core, the concave curve slides on the first convex curve of the rotor core. A position of the smallest gap clearance between the second convex curve and the stator does not change. A magnetic-flux-strength maximum position is not changed easily.
