Abstract
A planetary gear mechanism includes a sun gear attached to the motor rotation shaft to rotate about the central axis extending vertically, a fixed internal gear radially outside the sun gear, planetary gears radially outside the sun gear and radially inside the fixed internal gear to mesh with the sun gear and the fixed internal gear, a movable internal gear above the fixed internal gear and radially outside the planetary gears to mesh with the planetary gears and to rotate about the central axis, and a carrier that holds upper and lower surfaces of the planetary gears.
Claims17
A planetary gear mechanism that decelerates rotation input from a motor rotation shaft that rotates about a central axis extending in a vertical direction and outputs the rotation to an outside, the planetary gear mechanism comprising:
- a sun gear attached to the motor rotation shaft and rotatable about the central axis;
- a fixed internal gear located radially outside the sun gear;
- planetary gears that are located radially outside the sun gear and radially inside the fixed internal gear to mesh with the sun gear and the fixed internal gear;
- a movable internal gear that is located above the fixed internal gear and radially outside the planetary gears to mesh with the planetary gears, and to rotate about the central axis;
- and
- a carrier that holds upper and lower surfaces of the planetary gears.
