It relates to a planetary gear mechanism that can reduce noise, etc. and improve reliability.

伝達し出力させるようになっている。[Full back cover of the invention and its problems] Generally, as shown in Fig. 3, a planetary gear mechanism has an internal gear a.
and a sun tooth gi located approximately in the center of this internal gear a.
b, and a plurality of planetary gears C that are meshed with these gears a and b and rotate around the sun gear, and for example, when power is input from the planetary gear C side. , each lli gear C distributes the power equally and transmits it to the sun gear for output.

と太陽歯車すとの荷重等配分を達成するものである。Conventionally, the gear shaft d, which supports the sun gear and is integrally driven to rotate and transmit power, is supported in a substantially flowing state. Specifically, since a clutch or the like is generally interposed between the gear shaft d that transmits power and the driven object, one end of the gear shaft d is connected to the driven object by the connection of the clutch, etc. The other end has a ball that revolves around it!
4! It is supported by gear C. Supporting the gear shaft d in a substantially footing state equalizes the tooth surface pressure between the sun gear and each planetary gear C when outputting power to the driven object. This is a necessary configuration to enable equal power transmission from the sun gear to the sun gear. That is, when the tooth surface 1f force with the - planetary gear C is high and the tooth surface pressure with other planetary gears C is low, the sun gear can be moved from the side with higher tooth surface pressure to the side with lower tooth surface pressure. Each i star tooth it C
This achieves equal load distribution between the gear and the sun gear.
しかしながら従来にあっては次のような問題が６６ つ
ｌこ 。However, the conventional method has the following problems.
■ 歯車＠ｄを被駆動物と遊星歯車Ｃとの間で略フロー

場合歯車軸ｄはフリーとなる。■ Since the gear @d is supported in a substantially floating state between the driven object and the planetary gear C, the gear shaft d becomes free when the clutch or the like is disengaged.

遊星歯車Ｃの歯に送られることで無負的状態で空転され

発生さける虞れがあつＩご。In this disengaged state of the clutch, etc., the gear shaft d is idled in a non-negative state due to the sun gear being sent to the teeth of the planetary gear C, and the gear shaft d rattles without positioning and generates vibrations and noise. There is a risk that I will scream.

動を生じさせる虞れがあった。■ Also, since the gear shaft d is supported in a floating manner, a ring member e is fitted onto the gear shaft d in order to restrict the axial movement of the gear shaft d, but there is a gap for the purpose of smoothing the ring member e. There is a risk that vibrations in the axial direction will occur regardless of whether the engine is idling or transmitting power.
