- FIG. 7 shows a side view of the photovoltaic power generation apparatus 200
- FIG. 8 shows a rear view of the photovoltaic power generation apparatus 200.
- FIG. 9 is a cross-sectional view taken along line IX-IX in FIG.
- FIG. 10 is a cross-sectional view taken along line XX in FIG.
- the solar power generation device 200 is a modification of the solar power generation device 100, and the same components as those of the solar power generation device 100 may be denoted by the same reference numerals and description thereof may be omitted.

Therefore, only a part of the circumferential direction of the internal gear 2, the external gear 18, the ring gear 30, the input gear 26, the angular ball bearing 8, and the tapered roller bearing 13 is immersed in the lubricant.
- the gear transmission 10 does not require an amount of lubricant that fills the entire space in the case. Therefore, the amount of lubricant used is small.
- the solar power generation device 200 can reduce the amount of lubricant used by disposing the motor gear 40 below the axis 108 of the shaft 110.
- the lubricant may be filled up above the liquid level L, but preferably below the axis 108.
- the closed space needs to be filled with the lubricant in order to supply the motor gear 40 with the lubricant. That is, it is necessary to fill the gear transmission 10 with the lubricant and further fill the lubricant to the position where the motor gear 40 is disposed.
- the outer diameter of the motor gear 40 is smaller than the diameter of the shaft 110, that is, the diameter of the output shaft of the gear transmission 10. Therefore, the volume of the space in the gear transmission 10 is larger than the volume of the space around the motor gear 40.
- the solar power generation device 200 can reduce the amount of lubricant enclosed in the gear transmission 10 having a large space volume.
- the amount of lubricant to be enclosed in the gear transmission 10 will be described.
- the lubricant may be supplied to a part of the parts (gears and bearings) located on the uppermost side in the vertical direction among the gears and bearings constituting the gear transmission 10.
- the meshing of the external gear 18 and the internal gear 2 will be described. Even if not all of the enclosed space is filled with the lubricant, if some of the external teeth of the external gear 18 are immersed in the lubricant, each external tooth of the external gear 18 rotates the external gear 18.

Therefore, it suffices that a portion of the tapered roller bearing 13 in the circumferential direction is immersed in the lubricant.
- FIG. 11 shows a cross-sectional view along the line XI-XI in FIG. Reference symbol L indicates the height of the liquid surface of the lubricant.
- the gear transmission 10 includes three crankshafts 14, and an input gear 38 is fixed to each crankshaft 14.
- one circumferential roller bearing 13 is partially immersed in the lubricant, but the other two tapered roller bearings 13 are not immersed in the lubricant.
- the crankshaft 14 is supported by the carrier 6 (see FIG. 9), the crankshaft 14 moves around the axis 108 as the carrier 6 rotates.
- the height L of the lubricant liquid surface is a height that is in contact with a part of one tapered roller bearing 13 at the lowest position, the other tapered roller bearings 13 are also lubricated as the carrier 6 rotates. To touch.

- symbol 101 of FIG. 7 has shown the position of the sun at the time of the south middle. When the sun 101 goes south, the motor 12 and the lubricant are warmed most. Therefore, it is preferable that the motor 12 is located behind the main shaft 110. That is, the motor 12 is preferably arranged on the opposite side of the sun 101 with respect to the main shaft 110.
- a broken line 103 in FIG. 7 indicates a plane that includes the axis 108 and is orthogonal to the sun 101. The opposite side of the sun 101 means the range of the arrow A1.
- the motor 12 is disposed below the axis 108 of the main shaft 110 as described above, the amount of lubricant used can be reduced. Therefore, it is preferable to arrange the motor 116 in the range of the arrow A2. As the motor gear 40 is arranged below the axis 108, the amount of lubricant used can be reduced. In the photovoltaic power generation apparatus 200 of the present embodiment, the motor gear 40 is disposed vertically below the axis 108. A broken line 105 indicates a horizontal line including the axis 108.
- the motor 12 is preferably arranged in the range of the arrow A3.

Therefore, the motor 12 and the turning gear transmission 11 do not interfere with each other even though the motor 12 is arranged vertically below the main shaft 110. Therefore, the distance in the direction of the axis 114 between the main shaft 110 and the turning gear transmission 11 can be shortened. In other words, the distance in the vertical direction (axis 114 direction) between the gear transmission 10 and the turning gear transmission 11 can be shortened.
- the relay gear 36 As described above, by disposing the relay gear 36 between the ring gear 30 and the motor gear 40, an increase in the outer diameter of the ring gear 30 or the motor gear 40 can be suppressed.

Further, as described above, the motor 12 and the carrier 6 are disposed on one side in the direction of the axis 108 with respect to the relay gear 36. The relay gear 36 is supported on one end of the shaft 32 via a deep groove ball bearing 34. Thereby, since the distance between the motor 12 and the carrier 6 is close, the amount of lubricant used can be reduced.

- the gear transmission 10 and the motor 12 may be arranged such that the axis of the gear transmission 10 and the axis of the motor 12 intersect. Even in that case, the motor 12 and the carrier 6 (or the crankshaft 14) need only be positioned on one side of the axis 108 with respect to the relay gear 36.
- a bevel gear may be fixed to each of the shaft 32 and the output shaft 42 of the motor 12 and the bevel gears may be engaged with each other.
