技術分野
本考案は歯車変速機用歯車装置に関するもので
ある。[Detailed Description of the Invention] Technical Field The present invention relates to a gear device for a gear transmission.
従来技術
一般に歯車変速機用歯車装置は、歯車変速機内
の回転軸に複数の歯車を固定して歯車列を構成
し、従動側の回転軸の回転数を変えている。この
場合、回転歯車は変速機内でその下部をオイルに
浸しており、回転と共に歯車がオイルを引きずつ
てオイル面上部にオイルを導びき、遠心力で周囲
にオイルを跳ね飛ばしている。BACKGROUND ART In general, a gear device for a gear transmission has a plurality of gears fixed to a rotating shaft within the gear transmission to form a gear train, and changes the rotation speed of the driven-side rotating shaft. In this case, the lower part of the rotating gear is immersed in oil in the transmission, and as it rotates, the gear pulls the oil to the upper part of the oil surface, and the centrifugal force causes the oil to be splashed around.
従つて、このようにオイルに与えられるエネル
ギーは歯車のオイル撹拌損失となつてあらわれ、
特にこの撹拌損失は歯車の半径の４〜５乗に比例
するもので、歯車が大型になればなる程、その撹
拌損失を無視することができる。 Therefore, the energy given to the oil in this way appears as oil stirring loss in the gear,
In particular, this stirring loss is proportional to the fourth to fifth power of the radius of the gear, and the larger the gear, the more the stirring loss can be ignored.
考案の目的
本考案はかゝる歯車の撹拌損失を防止するもの
で、従来のような歯車の側面部をむき出しにする
のを避けて、オイル付着防止カバーを設けた歯車
変速機用歯車装置を提供することを目的とする。Purpose of the invention The present invention aims to prevent such agitation loss of gears, and instead of exposing the side surfaces of the gears as in the past, it is possible to create a gear device for a gear transmission equipped with a cover to prevent oil adhesion. The purpose is to provide.
考案の構成
即ち、本考案の構成は、歯車変速機内の回転軸
に固着された隣接ギヤ間にカバーを設けて、歯車
の歯部の下方側面にオイルの付着を防止したこと
を特徴とする。Structure of the Invention That is, the structure of the present invention is characterized in that a cover is provided between adjacent gears fixed to a rotating shaft in a gear transmission to prevent oil from adhering to the lower side surface of the teeth of the gear.
考案の効果
従つて、本考案の構成によれば、
歯車の側面がカバーによりむき出しになつてい
ないので、オイルが歯車の側面部に届かず、歯車
の側面で発生するオイルの撹拌損失を低減するだ
けでなく、オイルを少なくして十分な潤滑等が行
える利点を有する。Effects of the Invention Therefore, according to the configuration of the present invention, since the side surface of the gear is not exposed due to the cover, oil does not reach the side surface of the gear, thereby reducing oil agitation loss that occurs on the side surface of the gear. In addition, it has the advantage that sufficient lubrication can be achieved with less oil.
実施例
以下に本考案を図面の実施例に従つて説明す
る。Embodiments The present invention will be described below with reference to embodiments shown in the drawings.
図面は歯車変速機内部の歯車装置の要部を示
し、回転軸１に一の歯車２，３が固着されてい
る。この歯車は２個以上でも同様なのでその説明
を省略する。 The drawing shows a main part of a gear device inside a gear transmission, and one gear 2, 3 is fixed to a rotating shaft 1. The same applies to two or more gears, so the explanation thereof will be omitted.
また、一方の歯車２は他方の歯車３より大きい

４″が設けられる。これらカバー４，４′，４″は
歯車の噛み合いを防げない程度に歯車歯部より下
部にカバー上面が位置している。 Also, although one gear 2 is larger than the other gear 3, the same applies even if the gears are the same size. A cover 4 is inserted between the gears 2 and 3 to prevent oil from reaching the side surfaces of the gears. That is, the cover 4 is divided into two parts, and is press-fitted (attached by gluing, welding, etc.) between the gears so as to be sandwiched therebetween in a direction perpendicular to the axis. In this embodiment, a cover 4',
These covers 4, 4', 4'' have their upper surfaces located below the gear teeth to such an extent that they do not prevent the gears from meshing.
従つて、図示しないがオイル上面がオイル内の
カバー体積分だけ不要となり、車両の重量を減少
することができると共に歯車によるオイルの撹拌
損失が低減できる。 Therefore, although not shown in the drawings, the upper surface of the oil is no longer required by the volume covered within the oil, making it possible to reduce the weight of the vehicle and reduce oil agitation loss due to gears.
