〔産業上の利用分野〕
本発明は流体機械の可動翼装置に係り、特に小形可動翼
ポンプに好適なものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a movable vane device for a fluid machine, and is particularly suitable for a small movable vane pump.

ドに伝達し、インペラボス内でボールジヨイントを用い
インペラの回転運動に変換するのがほとんどであった。As shown in Figure 2, the conventional device transmits the blade operating force generated by the blade operating force generator in a direction parallel to the main axis to the operating rod as it is, and converts it into rotational motion of the impeller using a ball joint in the impeller boss. Most of the time I did it.

ペラの回転運動に変換する機構も提案されている。Furthermore, as described in Japanese Patent Application Laid-Open No. 159396/1983, a mechanism has been proposed in which a spiral groove mechanism and a gear mechanism are provided in an impeller boss to convert the rotational movement of the impeller.

に類する機構が採用されている例もあった。On the other hand, Japanese Patent Application Laid-Open No. 5.9-1735.97 uses a mechanism in which a blade operating force generator generates rotational motion and transmits this rotational motion to the rotational motion of an operating rod. There were also cases where similar mechanisms were used.

。万一潤滑剤が取扱液中に洩れた場合には公害の問題が
ある。The mechanism using a ball joint inside the impeller boss as shown in Figure 2 has limitations due to space constraints inside the impeller boss.
There is a problem that it cannot be applied to pumps with a diameter of 500 mm or less, and the mechanism described in JP-A-60-159396, which uses a helical groove and a gear mechanism inside the impeller boss, requires lubricant inside the impeller boss, making maintenance difficult. There was a problem above. If the lubricant were to leak into the liquid being handled, there would be a problem of pollution.

あった。In addition, the invention described in JP-A No. 59-173597 has a complex set of gears, and the gears rotate even when the blades are not being operated. There were problems such as the need to replenish lubricant.
本発明の目的は、小形ポンプに適用でき、かつ長寿命、
保守点検が容易、公害問題のない流体機械の可動翼装置
を得ることにある。The purpose of the present invention is to be applicable to small pumps, have a long life,
The object of the present invention is to obtain a movable blade device for a fluid machine that is easy to maintain and inspect and is free from pollution problems.
上記目的は、以下の機構を採用することにより達成でき
る。The above object can be achieved by employing the following mechanism.
（１）操作ロッドは回転運動で翼操作力を伝達し、イン
ペラボス内は歯車のみでインペラの回転運動に変換する
機構とする。(1) The operating rod transmits the blade operating force through rotational motion, and the mechanism is such that only gears inside the impeller boss convert it into rotational motion of the impeller.
（２）翼操作力発生装置は、主軸と平行方向の翼操作力
を発生する機構とする。(2) The blade operating force generating device is a mechanism that generates a blade operating force in a direction parallel to the main axis.
（３）翼操作力発生装置で発生する主軸と平行方向の翼
操作力を、操作ロッドの回転運動の変換するためのボー
ルジヨイントを設ける。(3) A ball joint is provided to convert the blade operating force generated by the blade operating force generator in a direction parallel to the main axis into the rotational motion of the operating rod.
操作ロッドを回転運動とし、インペラボス内に歯車のみ
を用いることにより、インペラボス内の機構が簡素化さ

ボス内の歯車は翼操作時のみ回転することから操作頻度
が少なく、歯面に特殊表面処理を施すことにより無潤滑
化が可能である。従って、潤滑剤の補給、潤滑剤の洩れ
による公害の問題を解消できる。By making the operating rod rotary and using only gears in the impeller boss, the mechanism in the impeller boss is simplified and can be applied to even small diameter pumps. Furthermore, since the gear inside the impeller boss rotates only when the blades are operated, they are operated less frequently, and special surface treatment on the tooth surfaces makes it possible to eliminate lubrication. Therefore, problems of lubricant replenishment and pollution caused by lubricant leakage can be solved.
翼操作力発生装置で主軸と平行方向の翼操作力を発生さ

ム部等の機素部品の長寿命化が図れる。This mechanism uses a screw to convert the rotational movement of the worm into movement parallel to the main axis when operating the wings.
The screw part and worm part have a structure that does not move. Therefore, the frequency of replenishment of lubricant is reduced, and the lifespan of elemental parts such as the threaded portion and the worm portion can be extended.

It is necessary to adopt a mechanism that generates this phenomenon.
