本発明は、エンジンに装備される遠心式のガバナ装置の
改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a centrifugal governor device installed in an engine.

耗が進むとガバナ特性が変化してしまうとともに、応答
性が更に悪化する傾向があった。Generally, as shown in FIG. 6, a centrifugal governor device has a governor shaft 7 supported slidably in the axial direction on the shaft end of an engine rotation shaft 3 such as a crankshaft or a camshaft. The arm portion 10 connected to the governor weight 9 that rotates together with the governor weight 9 is brought into contact with the 7 run :) 17 side surface of the governor shaft 7, and the governor shaft 7 is shifted in contact with the swinging displacement of the governor weight 9, and the governor shaft A structure is adopted in which the tip of the governor lever 15 is brought into contact with and suppressedly displaced at the outer end of the governor weight 9, but when the governor weight 9 swings, the arm portion IC)
Since the tip slides relative to the side surface of the 7 flange 17 of the governor shaft 7 in the radial direction, the responsiveness of the movement of the governor shaft 7 is poor due to the sliding contact resistance, and wear is likely to occur at the sliding contact portion. As wear progressed, the governor characteristics changed and the responsiveness tended to further deteriorate.
又、ガバナ軸７の先端とがバナレバ−１５の先端とが一
点で接当されるとともに、その接点で相対回転が行われ
るために、ここでの摩耗がはげしく、これによってもガ
バナ特性が変動する欠点があった。In addition, since the tip of the governor shaft 7 and the tip of the governor lever 15 come into contact at one point, and relative rotation occurs at that point of contact, wear is severe here, and this also causes variations in governor characteristics. There were drawbacks.
この発明は、上記従来構造の欠点を解消するためになさ
れたものであって、以下にその実施例の詳細を図面に基
づいて説明する。The present invention has been made to eliminate the drawbacks of the above-mentioned conventional structure, and details of embodiments thereof will be described below with reference to the drawings.

されている。As shown in Fig. 1, bearing 2 is attached to crankcase 1.
A key 4 for driving a camshaft is connected to a protruding part of a crankshaft 3, which is an example of an engine rotating shaft supported through a shaft, and a hole 5 drilled from the end of the shaft is tightly connected to a hole 5. A governor shaft 7 having a spherical head 6 fitted therein is inserted and supported so as to be slidable in the axial direction and swing freely around the spherical head 6.

１２が夫々ピン枢支連結されている。A pair of governor weights 9, 9 are supported by pins facing each other on the bracket (11M) fixed to the outer end surface of the gear 4.
Each bifurcated arm 1 is connected from the base of the vana weight 9
A relay link 12 made of sheet metal is connected between the tip of the guide shaft 7 and both ends of the arm portion 11 integrally formed on the tip side of the governor shaft 7.
12 are pivotally connected to each other by pins.

いる。Further, an intermediate member 14 is attached to the outer end of the governor shaft 7 through a bearing 13 so as to be relatively rotatable.
11 and the stupid lever 15 are pivotally connected by a pin 16.

軌跡を描き、これに対応してガバナ軸７は球状頭部６を
中心に揺動する。According to configuration 1-, as the crankshaft 3 rotates at high speed, the governor weights 9, 9 centrifugally swing, and the centrifugal force is transmitted to the governor shaft 7 via the arms 10, 10 and the relay links 12, 12, and The force is transmitted to the vane lever 15 via the intermediate members 1...1. At this time, as the governor lever 15 is suppressed and displaced, the pin 1G traces an arcuate trajectory, and the governor shaft 7 swings around the spherical head 6 in response to this.
尚、前記中１リンク１２は第５図に示すように逆向きに
取付けてもよい。Note that the middle 1 link 12 may be installed in the opposite direction as shown in FIG.

ることもできる。In addition, the governor shaft 7 is divided into a shaft portion that fits into the hole 5 of the crankshaft 3, and a shaft portion that is pivotally connected to the shaft portion so as to swing freely (1). It is also possible to implement the flexible shaft portion by pivotally connecting the vana weight 9 with the relay link 12.

とともに、枢支１４一
部での摩耗が著しく少ないのでガバナ特性を高められる
うえ、長期間維持でざるようになった。As explained above, in the governor device according to the present invention, one end of the governor weight and the governor shaft are pivotally connected via a relay link, so that only a slight rotational resistance is generated at the second pivot point. Therefore, it is possible to displace the governor shaft with high responsiveness to fluctuations in the rotational speed of the engine rotating shaft, and wear on a part of the pivot 14 is significantly less, so the governor characteristics can be improved and it can be maintained for a long time. Now I can't.

介して相対回動を許し、がっ、枢支連結して〃バナカを
伝達する構造としたので、ここでの摩耗も著しく減少し
、ガバナ特性を高めることができるうえ、耐久性の向」
二を図ることができた。In addition, since the outer end of the governor shaft and the lever lever are allowed to rotate relative to each other via bearings, and are pivotally connected to transmit the lever, wear here is also significantly reduced. In addition to improving the governor characteristics, it also improves durability.
I was able to achieve the second goal.
