この考案は遊星ギヤ減速装置、特に内部減速型
始動電動機（スタータ）に装着されるものの改良
に関する。[Detailed Description of the Invention] This invention relates to an improvement of a planetary gear reduction device, particularly one attached to an internal reduction type starting motor (starter).
従来の遊星歯車減速装置としては、添付図に後
述する如くの構成がなされており、各構成部材は
通常同一種類の部材、例えば鉄鋼部材に歯車を創
設し、遊星歯車減速装置の構成がなされていた。 A conventional planetary gear reduction device has a configuration as described later in the attached drawings, and each component is usually the same type of member, for example, a gear is created on a steel member, and the planetary gear reduction device is configured. Ta.
従来装置は以上の如くであつて、歯車の噛合騒
音が大である等の欠点があつた。 The conventional devices as described above had drawbacks such as high gear meshing noise.
この考案は上述の様な従来のものの欠点を改良
する為になされたもので、各歯車を各々異種構造
部材で構成する事で、以下に述べる優れた効果を
有する遊星ギヤ減速装置を提供する事を目的とし
ている。 This idea was made in order to improve the drawbacks of the conventional ones as mentioned above, and by constructing each gear with different structural members, it is possible to provide a planetary gear reduction device that has the excellent effects described below. It is an object.
以下、この考案による実施例を図について説明

歯車４は焼入（熱処理）鋼部材で構成される。 An embodiment according to this invention will be described below with reference to the drawings. In the figure, 1 is a planetary gear reduction device, 2 is a planetary gear, 3 is an internal gear (ring gear), and 4 is a sun gear, which are fixed to a rotating shaft (not shown) of a DC motor (not shown). In each of the above-mentioned gear devices, the planetary gear 2 is made of a hardened aluminum (or hardened aluminum alloy) member, and the internal gear 3 is made of a nylon resin containing a glass base material (filled with filler). It is made of a molded material, and the sun gear 4 is made of a hardened (heat treated) steel member.
次に、上記構成の動作について説明する。太陽

れる。 Next, the operation of the above configuration will be explained. The sun gear 4 is urged to rotate by a DC motor (not shown), and the planetary gear 2 is urged to rotate (however, the internal gear 3 is fixed by a machine frame (not shown)). The arm (not shown) of the planetary gear reduction device that moves planetary (or planetary) on the circumferential surface and is driven by this planetary gear 2 is rotated and is fixed to this arm (not shown). An engine (both not shown) is rotated (cranked) via the shaft.
上述によれば、各歯車強度が
太陽歯車＞遊星歯車＞内歯歯車 ……(1)
なる関係を有する事から、装置の歯車噛合による
回転騒音が吸収され、ギヤ噛合音が減少し、特に
高回転速度で駆動されるスタータに於て効果を奏
する。 According to the above, since the strength of each gear has the following relationship: sun gear > planetary gear > internal gear (1), rotational noise caused by gear meshing of the device is absorbed, gear meshing noise is reduced, and especially high This is effective in starters that are driven at rotational speed.
なお、上記実施例では、遊星歯車２は焼入アル

考案はこれに限定されるものではない。遊星歯車
２は、上記(1)式の関係を満足するように太陽歯車
４を構成する焼入鋼部材より硬度が小なる部材で
あれば、他の構造部材で構成されても良い。 In the above embodiment, the planetary gear 2 is made of a hardened aluminum member, but the present invention is not limited to this. The planetary gear 2 may be made of any other structural member as long as it satisfies the relationship of equation (1) above and has a lower hardness than the hardened steel member that makes up the sun gear 4.
以上の様に、この考案によれば、遊星ギヤ減速
装置１の各歯車装置〔遊星歯車２、内歯歯車３、
太陽歯車４〕を互いに異種構造部材で構成したの
で、装置の回転騒音が減少する等の極めて優れた
効果を奏する。 As described above, according to this invention, each gear device of the planetary gear reduction device 1 [planetary gear 2, internal gear 3,
Since the sun gear 4] is constructed from mutually different structural members, extremely excellent effects such as a reduction in rotational noise of the device can be achieved.
