しかしながら、上述の遊星歯車装置では、カバーはキャリアと一体となって回転するものであるため、潤滑油の外部からの油路の形成は困難なものとなる。また、ピニオンギヤに潤滑油を供給する油路の位置決めに対する十分な精度の確保も困難なものとなる。   However, in the above planetary gear device, since the cover rotates together with the carrier, it is difficult to form an oil passage from the outside of the lubricating oil. In addition, it is difficult to ensure sufficient accuracy for positioning of the oil passage for supplying the lubricating oil to the pinion gear.

本発明の遊星歯車装置は、潤滑油の外部からの油路の形成が容易で遊星歯車に供給する油路の位置決めを精度よく行なうことを目的の一つとする。また、本発明の遊星歯車装置は、遊星歯車の回転要素による回転により油路を形成する部材が回転するのを抑止することを目的の一つとする。   An object of the planetary gear device of the present invention is to form an oil passage from the outside of the lubricating oil easily and to accurately position the oil passage supplied to the planetary gear. Another object of the planetary gear device of the present invention is to suppress the rotation of the member that forms the oil passage due to the rotation of the planetary gear by the rotating element.

本発明の遊星歯車装置は、上述の目的の少なくとも一部を達成するために以下の手段を採った。   The planetary gear device of the present invention employs the following means in order to achieve at least a part of the above object.

It is a summary to provide.

この本発明の遊星歯車装置では、ケースの遊星歯車の回転要素の軸方向端部に形成された凹部に凸部が嵌合するよう油路形成部材を遊星歯車とケースとの間に配設することにより、ケースとにより遊星歯車に貫通孔を介して潤滑油を供給するための油路を形成する。ケースに形成された凹部と油路形成部材に形成された凸部とが嵌合するから、遊星歯車に供給する油路の位置決めを精度よく行なうことができると共に遊星歯車の回転要素による回転により油路形成部材が回転するのを抑止することができる。もとより、ケースと油路形成部材とにより油路を形成するから、潤滑油の外部からの油路の形成を容易なものとすることができる。   In the planetary gear device of the present invention, the oil passage forming member is disposed between the planetary gear and the case so that the convex portion fits into the concave portion formed at the axial end of the rotating element of the planetary gear of the case. Thus, an oil passage for supplying lubricating oil to the planetary gear through the through hole is formed by the case. Since the concave portion formed in the case and the convex portion formed in the oil passage forming member are fitted, the oil passage supplied to the planetary gear can be accurately positioned and the oil is obtained by the rotation of the planetary gear by the rotating element. It is possible to prevent the path forming member from rotating. Of course, since the oil passage is formed by the case and the oil passage forming member, it is possible to easily form the oil passage from the outside of the lubricating oil.

The case may be a case in which the first electric motor is housed on the opposite side of the planetary gear from the side on which the oil passage forming member is disposed. Furthermore, the case may be a case that houses the second electric motor so that the oil passage forming member is sandwiched by the planetary gear. In this case, the planetary gear device is housed in the same case as the second planetary gear, the first electric motor, the second electric motor, and the like, so that it can be made compact.

次に、本発明を実施するための最良の形態を実施例を用いて説明する。   Next, the best mode for carrying out the present invention will be described using examples.

図１は本発明の一実施例としての遊星歯車装置２０が組み込まれた駆動装置１０の構成の概略を示す構成図であり、図２は図１のＡ−Ａ断面を示す断面図であり、図３は駆動装置１０の構造を模式的に示す模式図であり、図４は実施例の遊星歯車装置２０が備える油路形成部材としてのオイルレシーバ４０の外観を示す斜視図である。   FIG. 1 is a configuration diagram showing an outline of a configuration of a drive device 10 in which a planetary gear device 20 according to an embodiment of the present invention is incorporated. FIG. 2 is a cross-sectional view showing a cross section taken along line AA of FIG. FIG. 3 is a schematic view schematically showing the structure of the drive device 10, and FIG. 4 is a perspective view showing an external appearance of an oil receiver 40 as an oil passage forming member provided in the planetary gear device 20 of the embodiment.

実施例の駆動装置１０は、図１および図３に示すように、二つのモータＭＧ１，ＭＧ２と、この二つのモータＭＧ１，ＭＧ２の間に配置された二つの遊星歯車３０，３５と、ケースと遊星歯車３５との間に配置されたオイルレシーバ４０とを、右からモータＭＧ１，遊星歯車３０，遊星歯車３５，オイルレシーバ４０，モータＭＧ２の順に配置して一体のケースＣＳに収納している。ここで、実施例の遊星歯車装置２０としては、二つの遊星歯車３０，３５とオイルレシーバ４０とケースＣＳとが相当する。なお、図１および図３には、エンジンのトルク脈動を緩和するダンパ６４や遊星歯車３０，３５のリングギヤに連結された連結ギヤ６０，この連結ギヤ６０に連結しているデファレンシャルギヤ６１も示されている。   As shown in FIGS. 1 and 3, the driving device 10 of the embodiment includes two motors MG1 and MG2, two planetary gears 30 and 35 disposed between the two motors MG1 and MG2, and a case. The oil receiver 40 disposed between the planetary gear 35 and the planetary gear 35 is arranged in the order of the motor MG1, the planetary gear 30, the planetary gear 35, the oil receiver 40, and the motor MG2 from the right and accommodated in an integrated case CS. Here, as the planetary gear device 20 of the embodiment, two planetary gears 30, 35, an oil receiver 40, and a case CS correspond. 1 and 3 also show a damper 64 for reducing engine torque pulsation, a connecting gear 60 connected to the ring gears of the planetary gears 30 and 35, and a differential gear 61 connected to the connecting gear 60. ing.

オイルレシーバ４０は、図４に示すように、環状の板状部材として構成されており、取っ手部４２が折り曲げ加工により形成されている。オイルレシーバ４０の環状部には対面するよう二つの開口した円柱形状の凸部４４ａ，４４ｂがバーリング加工により形成されており、同じく環状部には略均等に５つのオイル用貫通孔４６ａ〜４６ｅが穴あけ加工により形成されている。   As shown in FIG. 4, the oil receiver 40 is configured as an annular plate-like member, and the handle portion 42 is formed by bending. Two annular cylindrical protrusions 44a and 44b are formed on the annular portion of the oil receiver 40 so as to face each other by burring. Similarly, five annular oil through holes 46a to 46e are formed in the annular portion. It is formed by drilling.

ケースＣＳのオイルレシーバ４０が配置される端面には、図１および図２に示すように、凸部４４ａ，４４ｂが丁度嵌合するよう二つの凹部５０ａ，５０ｂが穴あけ加工により形成されており、同じくオイルレシーバ４０が配置される端面には、取っ手部４２の部位からオイル用貫通孔４６ａ〜４６ｅに連通するよう潤滑オイルの油路を形成するオイル溝５２が形成されている。   As shown in FIGS. 1 and 2, two concave portions 50 a and 50 b are formed by drilling on the end surface of the case CS where the oil receiver 40 is disposed, so that the convex portions 44 a and 44 b are just fitted. Similarly, an oil groove 52 that forms an oil passage for lubricating oil is formed on the end surface where the oil receiver 40 is disposed so as to communicate with the oil through holes 46 a to 46 e from the portion of the handle portion 42.

ケースＣＳにオイルレシーバ４０が取り付けられると、図１の左下の拡大部分や図２に示すように、ケースＣＳのオイルレシーバ４０が配置される端面に形成された二つの凹部５０ａ，５０ｂにオイルレシーバ４０に形成された凸部４４ａ，４４ｂが嵌合する。これにより、オイルレシーバ４０の位置決めを高精度に行ない、隣接する遊星歯車３５の回転要素の回転に対してもオイルレシーバ４０の回転を抑止する。また、ケースＣＳにオイルレシーバ４０を取り付けることによりケースＣＳに形成したオイル溝５２はオイルレシーバ４０の面と共に潤滑オイルの油路を形成し、ケースＣＳの取っ手部４２近傍から供給された潤滑オイルをオイルレシーバ４０に形成された５つのオイル用貫通孔４６ａ〜４６ｅに導いて遊星歯車３５の回転要素側に供給する。なお、図１の拡大部分は、波線の上半分についてはオイル溝５２やオイル用貫通孔４６ｂを示し、波線の下半分については凹部５０ａや凸部４４ａを示した。   When the oil receiver 40 is attached to the case CS, as shown in the lower left enlarged portion of FIG. 1 and the end surface where the oil receiver 40 of the case CS is disposed as shown in FIG. The convex parts 44a and 44b formed in 40 are fitted. Thereby, the positioning of the oil receiver 40 is performed with high accuracy, and the rotation of the oil receiver 40 is suppressed even when the rotating element of the adjacent planetary gear 35 rotates. Further, the oil groove 52 formed in the case CS by attaching the oil receiver 40 to the case CS forms an oil passage for the lubricating oil together with the surface of the oil receiver 40, and the lubricating oil supplied from the vicinity of the handle portion 42 of the case CS is formed. The oil is guided to five oil through holes 46 a to 46 e formed in the oil receiver 40 and supplied to the rotating element side of the planetary gear 35. The enlarged portion of FIG. 1 shows the oil groove 52 and the oil through hole 46b for the upper half of the wavy line, and the concave portion 50a and the convex portion 44a for the lower half of the wavy line.

以上説明した実施例の遊星歯車装置２０によれば、オイルレシーバ４０の環状部に二つの開口した円柱形状の凸部４４ａ，４４ｂを形成すると共にケースＣＳのオイルレシーバ４０が配置される端面における凸部４４ａ，４４ｂが整合する部位に二つの凹部５０ａ，５０ｂを形成し、オイルレシーバ４０に形成した凸部４４ａ，４４ｂをケースＣＳに形成した凹部５０ａ，５０ｂに嵌合するようケースＣＳにオイルレシーバ４０を取り付けることにより、遊星歯車３５の回転要素に供給する潤滑オイルの油路の位置決めを精度よく行なうことができると共に遊星歯車３５の回転要素による回転によりオイルレシーバ４０が回転するのを抑止することができる。   According to the planetary gear device 20 of the embodiment described above, the cylindrical receivers 44a and 44b having two openings are formed in the annular part of the oil receiver 40, and the protrusions on the end face where the oil receiver 40 of the case CS is disposed. Two recesses 50a and 50b are formed in the part where the parts 44a and 44b are aligned, and the protrusions 44a and 44b formed in the oil receiver 40 are fitted into the recesses 50a and 50b formed in the case CS. By attaching 40, the oil path of the lubricating oil supplied to the rotating element of the planetary gear 35 can be accurately positioned, and the oil receiver 40 is prevented from rotating due to the rotation of the planetary gear 35 by the rotating element. Can do.

実施例の遊星歯車装置２０では、オイルレシーバ４０に二つの凸部４４ａ，４４ｂを形成すると共にケースＣＳのオイルレシーバ４０を配置する端面における凸部４４ａ，４４ｂが整合する部位に二つの凹部５０ａ，５０ｂを形成するものとしたが、オイルレシーバ４０に三つ以上の凸部を形成すると共にケースＣＳのオイルレシーバ４０を配置する端面における各凸部が整合する部位に三つ以上の凹部を形成するものとしてもよいし、オイルレシーバ４０に一つの凸部を形成すると共にケースＣＳのオイルレシーバ４０を配置する端面におけるこの凸部が整合する部位に一つの凹部を形成するものとしてもかまわない。   In the planetary gear device 20 according to the embodiment, the two concave portions 50a, 44b are formed at a portion where the convex portions 44a, 44b on the end surface of the case CS where the oil receiver 40 is disposed are aligned. 50b is formed, but three or more convex portions are formed on the oil receiver 40, and three or more concave portions are formed at a portion where the convex portions on the end surface of the case CS where the oil receiver 40 is arranged are aligned. Alternatively, one convex portion may be formed on the oil receiver 40 and one concave portion may be formed at a portion where the convex portion is aligned on the end surface of the case CS where the oil receiver 40 is disposed.

実施例の遊星歯車装置２０では、オイルレシーバ４０の環状部にバーリング加工により二つの凸部４４ａ，４４ｂを形成するものとしたが、こうした凸部４４ａ，４４ｂの形成はバーリング加工に限定されるものではなく、如何なる手法によって形成するものとしてもかまわない。   In the planetary gear device 20 of the embodiment, the two convex portions 44a and 44b are formed on the annular portion of the oil receiver 40 by burring, but the formation of the convex portions 44a and 44b is limited to burring. Rather, it may be formed by any method.

実施例の遊星歯車装置２０では、オイルレシーバ４０の環状部に二つの開口した円柱形状の凸部４４ａ，４４ｂを形成するものとしたが、凸部４４ａ，４４ｂは、開口している必要はなく、閉口した円柱形状として形成するものとしてもよい。また、その形状は円柱形状に限られるものではなく、角柱形状としてもかまわない。この場合、オイルレシーバ４０の位置決めが行なわれ、遊星歯車３５の回転要素の回転により回転しないように保持すればよいから、ケースＣＳの凹部５０ａ，５０ｂの形状は凸部４４ａ，４４ｂの形状に完全に一致する必要はない。例えば、凸部４４ａ，４４ｂを断面が正八角形の角柱形状に形成し、凹部５０ａ，５０ｂを正四角形の断面となるよう形成するものとしてもよい。   In the planetary gear device 20 of the embodiment, the cylindrical convex portions 44a and 44b having two openings are formed in the annular portion of the oil receiver 40. However, the convex portions 44a and 44b do not need to be opened. Alternatively, it may be formed as a closed cylindrical shape. Further, the shape is not limited to a cylindrical shape, and may be a prismatic shape. In this case, since the oil receiver 40 is positioned and held so as not to rotate by the rotation of the rotating element of the planetary gear 35, the shape of the concave portions 50a and 50b of the case CS is completely the shape of the convex portions 44a and 44b. There is no need to match. For example, the convex portions 44a and 44b may be formed in a prismatic shape having a regular octagonal cross section, and the concave portions 50a and 50b may be formed to have a regular quadrangular cross section.

実施例の遊星歯車装置２０では、オイルレシーバ４０に５つのオイル用貫通孔４６ａ〜４６ｅを形成するものとしたが、オイルレシーバ４０に形成するオイル用貫通孔の数は４つ以下としてもよいし、６つ以上としてもよい。   In the planetary gear device 20 of the embodiment, the five oil through holes 46a to 46e are formed in the oil receiver 40, but the number of oil through holes formed in the oil receiver 40 may be four or less. 6 or more.

実施例の遊星歯車装置２０では、モータＭＧ１やモータＭＧ２と共にケースＣＳに収納されるものとしたが、こうしたモータＭＧ１やモータＭＧ２と共にケースに収納されないものとしても差し支えない。   In the planetary gear device 20 according to the embodiment, the motor MG1 and the motor MG2 are housed in the case CS, but the motor MG1 and the motor MG2 may not be housed in the case.

実施例の遊星歯車装置２０では、二つの遊星歯車３０，３５を備えるものとしたが、一つの遊星歯車を備えるものとしてもかまわない。   Although the planetary gear device 20 of the embodiment includes the two planetary gears 30 and 35, the planetary gear device 20 may include one planetary gear.

以上、本発明を実施するための最良の形態について実施例を用いて説明したが、本発明はこうした実施例に何等限定されるものではなく、本発明の要旨を逸脱しない範囲内において、種々なる形態で実施し得ることは勿論である。   The best mode for carrying out the present invention has been described with reference to the embodiments.
