Description

本発明は、請求項１の前文に記載の内歯車装置に関する。   The present invention relates to an internal gear device according to the preamble of claim 1.

このような内歯車装置は、例えば、ＤＥ１００５８８８３Ａ１により公知である。その本質的な構成部材は、内歯中空歯車，外歯ピニオン、および双方の歯車の間の三日月形スペースをふさぐ充填部材である。充填部材は、２分割されている。半径方向内方のピニオン側の部分は、ピニオンの歯に当接し、半径方向外方の中空歯車側の部分は、中空歯車の歯に当接する。充填部材の双方の部分は、ハウジングに支持され、その固有の軸のまわりに僅かに回転できるストッパピンに支持されている。   Such an internal gear device is known, for example, from DE10058883A1. The essential components are an internal hollow gear, an external pinion, and a filling member that fills the crescent space between the two gears. The filling member is divided into two. The radially inner pinion side portion abuts on the pinion teeth, and the radially outward hollow gear side portion abuts on the hollow gear teeth. Both parts of the filling member are supported by a housing and supported by a stopper pin that can rotate slightly about its own axis.

充填部材の部分は、運転時に歯車の運動に追従し、半径方向の長い遊びを補償できるよう、可動的に支持されている。   The portion of the filling member is movably supported so that it can follow the movement of the gear during operation and compensate for long radial play.

充填部材の部分に作用する液圧力を制御するため、内歯車装置のハウジングには、制御スリットが設けられている。液圧力は、この制御スリットを介して、充填部材の部分に作用し、かくして、上記部分は、歯車の歯先に押圧されるその最適位置に、少なくとも部分的に保持される。   In order to control the hydraulic pressure acting on the portion of the filling member, a control slit is provided in the housing of the internal gear device. The hydraulic pressure acts on the part of the filling member via this control slit, so that said part is at least partly held in its optimum position pressed against the gear teeth.

充填部材は、運転時に異なる圧力下にある２つのスペースを相互に限定する。圧力スペース内に一定の運転圧力が支配しない場合は、可変の力が充填部材に作用する。かくして、充填部材の部分の「フラッタ」が誘起されることになる。この場合、充填部材の１つの部分は、関連の歯列に当接し、充填部材の他の部分は、歯列に当接しない。この状態は、常に変化する。   The filling member mutually limits two spaces that are under different pressures during operation. If a constant operating pressure does not dominate in the pressure space, a variable force acts on the filling member. Thus, “flutter” of the portion of the filling member is induced. In this case, one part of the filling member abuts the associated dentition and the other part of the filling member does not abut the dentition. This state always changes.

ＤＥ１０２０４０３３４９Ａ１の場合、充填ピン、即ち、ストッパの対応する構成によって、課題を解決するようになっている。充填部材の部分の当接面の面積重心は、特定の態様で調節され、従って、加えられたモーメントは、装置の運転条件とは無関係に、その方向を保持する。   In the case of DE1020403349A1, the problem is solved by the corresponding configuration of the filling pins, ie stoppers. The area centroid of the abutment surface of the part of the filling member is adjusted in a specific manner, so that the applied moment maintains its direction regardless of the operating conditions of the device.

しかし、この場合、実際的な問題点が生ずる。特に、意図する調節状態を、必要な精度で形成することはできない。   In this case, however, a practical problem arises. In particular, the intended adjustment state cannot be formed with the required accuracy.

運転媒体内に遊離空気が存在する場合には、特に問題がある。その理由は、遊離空気、即ち、気泡の存在時に液体の弾性率が減少するからである。内歯車装置の遠心力によって、外部範囲、即ち、中空歯車の範囲の液体は、内部範囲、即ち、ピニオンシャフトの範囲の液体よりも密である。その結果、ピニオンの歯溝の圧力は、遅延して生成される。他方、中空歯車の歯溝の圧力は、ほぼ正常に生成される。更に、充填部材の双方の部分の間の間隙には、同じくほぼ「正常に」圧力媒体が供給される。   There is a particular problem when free air is present in the operating medium. The reason is that the elastic modulus of the liquid decreases in the presence of free air, ie, bubbles. Due to the centrifugal force of the internal gear device, the liquid in the outer range, ie in the hollow gear range, is more dense than the liquid in the inner range, ie in the pinion shaft range. As a result, the pinion tooth gap pressure is delayed. On the other hand, the pressure in the tooth space of the hollow gear is generated almost normally. In addition, the gap between both parts of the filling member is also supplied with a “normally” pressure medium.

その結果、充填部材のピニオン近傍の部分は、ピニオンの歯先により、強く押圧される。従って、ポンプの不安定性および摩耗が誘起され、極端な場合には、故障が発生する。   As a result, the portion near the pinion of the filling member is strongly pressed by the tip of the pinion. Accordingly, pump instability and wear are induced, and in extreme cases, failure occurs.

本発明の課題は、充填部材の部分のフラッタが避けられるよう、請求項１の前文に記載の内歯車装置を構成することにある。即ち、充填部材の１つの部分が、一時的に、または常に、その関連する歯車の歯先に対して、充填部材の他の部分よりも強く押圧されるが、上記他の部分は、その関連の歯車の歯先に押圧されないようにすることを意図するものである。遊離空気を含む媒体の場合も、問題を避けることは、特に重要である。   SUMMARY OF THE INVENTION An object of the present invention is to configure an internal gear device according to the preamble of claim 1 so as to avoid fluttering of a filling member portion. That is, one part of the filling member is temporarily or always pressed against the tooth tip of its associated gear more strongly than the other part of the filling member, but the other part is It is intended not to be pressed against the tooth tip of the gear. It is particularly important to avoid problems even in the case of media containing free air.

この課題は、請求項１における特徴事項によって解決される。   This problem is solved by the features of claim 1.

これにもとづき、中空歯車の歯溝と、ピニオンの歯溝との間に延び、（周面方向に見て）充填部材の範囲に達する伝送接続を設ける。上記の伝送接続は、側板の内部にあるボアによって構成される。   Based on this, a transmission connection is provided which extends between the tooth space of the hollow gear and the tooth space of the pinion and reaches the range of the filling member (as viewed in the circumferential direction). Said transmission connection is constituted by a bore inside the side plate.

添付の図面を参照して、本発明および先行技術について、詳細に説明する。   The present invention and the prior art will be described in detail with reference to the accompanying drawings.

図１に示す内歯車装置は、第１実施例であり、中空歯車１およびこれと噛み合うピニオン２を示してある。ピニオン２は、中空歯車１に対して、偏心状態に設けられている。   The internal gear device shown in FIG. 1 is a first embodiment, and shows a hollow gear 1 and a pinion 2 meshing therewith. The pinion 2 is provided in an eccentric state with respect to the hollow gear 1.

中空歯車１とピニオン２との間には、圧力の異なる２つの範囲を相互に限定する三日月状充填部材３を設けてある。充填部材３は、ピニオン側の部分３．１と、中空歯車側の部分３．２とに分割されている。ピニオン側部分３．１は、中空歯車の歯先に当接し、中空歯車側部分３．２は、中空歯車の歯先に当接する。充填部材の双方の部分３．１，３．２は、ストッパピン４に支持されている。   A crescent-shaped filling member 3 is provided between the hollow gear 1 and the pinion 2 to mutually limit two ranges having different pressures. The filling member 3 is divided into a pinion side portion 3.1 and a hollow gear side portion 3.2. The pinion side portion 3.1 abuts on the tooth tip of the hollow gear, and the hollow gear side portion 3.2 abuts on the tooth tip of the hollow gear. Both parts 3.1, 3.2 of the filling member are supported on the stopper pin 4.

図２の内歯車装置は、基本的に、図１の内歯車装置と同一の構成を有している。しかし、図２によると、本発明の特徴を、正確に把握することができる。   The internal gear device of FIG. 2 basically has the same configuration as the internal gear device of FIG. However, according to FIG. 2, the features of the present invention can be accurately grasped.

図２には、中空歯車１，ピニオン２、双方の部分３．１および３．２を有する充填部材３およびストッパピン４を示してある。ストッパピン４は、その固有の縦軸４．１のまわりに回転できる。このストッパピン４は、充填部材の双方の部分３．１，３．２の対応する平坦面を支持する当接面４．２を有する。この形状と構成にもとづき、運転条件に応じて、充填部材の部分３．１，３．２の位置を、確実に調節できる。   FIG. 2 shows a filling member 3 and a stopper pin 4 having a hollow gear 1, a pinion 2, both parts 3.1 and 3.2. The stopper pin 4 can rotate around its own longitudinal axis 4.1. This stopper pin 4 has an abutment surface 4.2 that supports the corresponding flat surfaces of both parts 3.1, 3.2 of the filling member. Based on this shape and configuration, the positions of the filling member portions 3.1, 3.2 can be reliably adjusted according to the operating conditions.

充填部材の双方の部分３．１，３．２の間には、間隙５が存在する。この間隙５は、パッキン６，７によって密閉されている。従って、媒体は、間隙５の一端から他端へ、間隙を介して流動することはできない。しかし、双方のパッキン６，７の間の間隙５の範囲には、接続ボア１１（図２を参照して詳細に説明する）を介して、高圧媒体を充填できる。   There is a gap 5 between both parts 3.1, 3.2 of the filling member. The gap 5 is sealed with packings 6 and 7. Therefore, the medium cannot flow from one end of the gap 5 to the other end through the gap. However, the gap 5 between the two packings 6 and 7 can be filled with a high-pressure medium via a connection bore 11 (described in detail with reference to FIG. 2).

作業媒体に不溶の空気が、気泡の形で存在する場合、次の現象が起こる。即ち、気泡は、好ましくは、半径方向内方の範囲に集まり、他方、半径方向外方の範囲の作業媒体は、少量の気泡を含む。その結果、充填部材の半径方向内方のピニオン近傍の部分３．１は、充填部材の半径方向外方の中空歯車近傍の部分３．２よりも負荷を受けない。   When insoluble air is present in the working medium in the form of bubbles, the following phenomenon occurs: That is, the bubbles preferably collect in the radially inward range, while the radially outer range of the working medium contains a small amount of bubbles. As a result, the portion 3.1 near the pinion radially inward of the filling member is less loaded than the portion 3.2 near the hollow gear radially outward of the filling member.

従って、充填部材のピニオン近傍の部分３．１は、それ自体−即ち、本発明に係る構成によらずに−比較的大きい力で、ピニオンの歯先に押圧される。しかし、これは、本発明に係る構成によって阻止される。これには、中空歯車の歯先と、ピニオンの歯先との間の伝送接続が役立つ。   Accordingly, the portion 3.1 of the filling member in the vicinity of the pinion is pressed against the tooth of the pinion by itself—that is, regardless of the configuration according to the invention—with a relatively large force. However, this is prevented by the arrangement according to the invention. For this purpose, a transmission connection between the tooth tip of the hollow gear and the tooth tip of the pinion is useful.

図示の実施例の場合、この接続は、ハウジングの構成部材である双方の側板のうち、少なくとも１つの側板のボア、およびダクトによって形成される。これは、図２から明らかな如く、ボア９，１０および接続ボア１１である。接続ボア１１は、側板（図示してない）によって完全に囲まれている。しかし、この代わりに、歯車に向く側板内面に、溝をフライス加工することも考えられる。   In the case of the illustrated embodiment, this connection is formed by a bore and a duct of at least one of the side plates that are components of the housing. These are the bores 9 and 10 and the connection bore 11 as is apparent from FIG. The connection bore 11 is completely surrounded by a side plate (not shown). However, it is also conceivable to mill the grooves on the inner surface of the side plate facing the gear.

双方のボア９，１０、および接続ボア１１の本発明に係る構成にもとづき、次のことが達成される。   Based on the configuration according to the invention of both the bores 9, 10 and the connection bore 11, the following is achieved.

即ち、ピニオン２の１つの歯溝−図示の実施例の場合、２．１で示してある−は、伝送接続９，１０，１１を介して、中空歯車の１つの歯溝−図示の実施例の場合、１．１で示してある−と伝送接続される。かくして、歯溝２．１には、短時間で、高圧媒体（一般に高圧オイル）が供給される。   That is, one tooth groove of the pinion 2 -in the case of the illustrated embodiment, indicated by 2.1 -is one tooth groove of the hollow gear via the transmission connections 9,10,11-the illustrated embodiment. In this case, the transmission connection is made as shown in 1.1. Thus, a high pressure medium (generally high pressure oil) is supplied to the tooth gap 2.1 in a short time.

ボア９は、歯列データにもとづき、最も有効な制御角を生ずる半径Ｒに設けるのが最良である。ボア９の制御開始は、角度αによって調節される。   The bore 9 is best provided at a radius R that produces the most effective control angle based on dentition data. The control start of the bore 9 is adjusted by the angle α.

双方のパッキン６，７の間の間隙５は、接続ボア１１に接続されている。従って、同じく高圧オイルの供給を受ける。   The gap 5 between the two packings 6 and 7 is connected to the connection bore 11. Therefore, the high-pressure oil is also supplied.

更に、同じく側板に加工した双方の制御スリット１２，１３を示してある。制御スリット１２は、歯溝２．１と伝送接続され、制御スリット１３は、接続ボア１１と伝送接続されている。この回路によって、歯溝１．１，２．１の圧力、および双方のパッキン６，７の間の間隙５の圧力は、運転条件に自動的に適合される。   Furthermore, both control slits 12 and 13 processed into the side plate are also shown. The control slit 12 is transmission-connected to the tooth gap 2.1, and the control slit 13 is transmission-connected to the connection bore 11. With this circuit, the pressure in the tooth spaces 1.1, 2.1 and the pressure in the gap 5 between both packings 6, 7 are automatically adapted to the operating conditions.

本発明に係る実施例は、高圧媒体が不溶の空気を、全く、またはほとんど含まない場合にも機能する。   Embodiments according to the invention also work when the high pressure medium contains no or little insoluble air.

図３に示した内歯車装置は、先行技術に属する。この内歯車装置は、中空歯車１，ピニオン２，充填部材３およびストッパピン４を含んでいる。間隙５は、パッキン６，７によって密閉されている。上記間隙は、軸線方向ボア１４，１５および接続ボア１６を介して、中空歯車の歯溝１．１と伝送接続する。回転角による圧力構成は、制御スリット１２，１３を介して、歯溝１．１および２．１のために行われる。   The internal gear device shown in FIG. 3 belongs to the prior art. The internal gear device includes a hollow gear 1, a pinion 2, a filling member 3, and a stopper pin 4. The gap 5 is sealed with packings 6 and 7. The gap is in transmission connection with the tooth space 1.1 of the hollow gear via the axial bores 14, 15 and the connection bore 16. The pressure configuration by the angle of rotation is effected for the tooth spaces 1.1 and 2.1 via the control slits 12,13.

しかし、先行技術のこの装置に欠けているものは、歯溝１．１，２．１の間の伝送接続である。   However, what is lacking in this prior art device is the transmission connection between the tooth spaces 1.1, 2.1.
