ていた遊星歯車５の点検整備が可能になる。 The present invention eliminates the drawbacks of the conventional methods described above, and one method will be described with reference to the drawings. 3 is fixed and the input shaft 1 is rotated, the planetary gear 5 receives a reaction force from the internal gear 6 of the sun gear 2, this reaction force is transmitted to the planetary shaft 10, and the carrier 8 rotates. Therefore, the planetary gear 5 rotates (rotates) by itself and also rotates (revolutions) about the input/output axis together with the carrier 8, and the planetary gear 5 located below moves upward. At this point, use bolt 9 to tighten carrier 8.
By fixing the internal gear 6 to the base plate 7 and moving the internal gear 6 in the axial direction until it disengages from the gear 4 and the planetary gear 5 (as shown by the chain line in the drawing), the planetary gear 5 located below can be inspected. Maintenance becomes possible.

５を上方に移動させることができる。 Conversely, a similar effect occurs by fixing the input shaft 1 and rotating the output shaft 3 or the internal gear 6.
The planetary gear 5 located below the star type planetary gear device can be moved upward.
入力軸側又は出力軸側の回転力は何れの方法で
与えてもよい。 The rotational force on the input shaft side or the output shaft side may be applied by any method.

点検整備作業ができる。 As described above, in the present invention, between the sun gear connected to the input shaft and the internal gear connected to the output shaft,
In a star-type planetary gear device consisting of a plurality of planetary gears supported via planetary shafts on a carrier fixed to a stationary member with a fixture such as a bolt, the carrier can be rotated by removing the fixture from the stationary member. In this state, the output shaft side is fixed and the input shaft side is rotated, or the input shaft side is fixed and the output shaft side is rotated.
This is an inspection and maintenance method for a star type planetary gear device in which the carrier is rotated to rotate the planetary gear and the planetary shaft located below the gear device upward, and the planetary gear or the planetary shaft is inspected and maintained.1 Planetary gears can be inspected and maintained without disassembling the entire gear system.
２ 作業時間が大巾に短縮される。2. Working time is drastically reduced.
