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.
遠心式ガバナ装置は、一般には第４図に示すよ

るために、その摺接抵抗でガバナ軸２１の移動の
応答性が悪く、又、その摺接部で摩耗が生じやす
く、摩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つた。 Generally, as shown in FIG. 4, a centrifugal governor device has a governor shaft 21 supported slidably in the axial direction on the shaft end of an engine rotation shaft 20 such as a crankshaft or a camshaft. An arm portion 23 connected to the governor weight 22 that rotates together with the governor weight 22 is brought into contact with the side surface of the flange 24 of the governor shaft 21, and as the governor weight 22 swings, the governor shaft 21
The structure is such that the outer end of the governor shaft 21 contacts and shifts the tip of the governor lever 25, but when the governor weight 22 swings, the tip of the arm portion 23 moves into contact with the governor lever 25. axis 2
Since the side surface of the flange 24 of the first flange 24 slides relative to the other in the radial direction, the responsiveness of the movement of the governor shaft 21 is poor due to the sliding contact resistance, and wear is likely to occur at the sliding contact portion, and as the wear progresses, the governor shaft 21 As the characteristics changed, there was a tendency for the responsiveness to further deteriorate.
又、ガバナ軸の先端とガバナレバーの先端とが
一点で接当されるとともに、その接点で相対回転
が行なわれるために、ここでの摩耗が激しくこれ
によつてもガバナ特性が変動する欠点があつた。 In addition, since the tip of the governor shaft and the tip of the governor lever are in contact at one point, and relative rotation occurs at that point of contact, there is a drawback that wear is severe here, which also causes variations in governor characteristics. Ta.

応答性が悪くなる。 Moreover, if the swinging force of the governor weight 22 is unevenly applied to the governor shaft 21, the sliding portion 26 between the governor shaft 21 and the engine rotation shaft 20
This will distort the governor characteristics, and the sliding resistance at the sliding portion 26 will worsen the responsiveness of the movement of the governor shaft 21.

み支持するようにするものである。 This invention was proposed in order to eliminate the drawbacks of the above-mentioned conventional structure. The information is transmitted to the governor lever via an intermediate transmission mechanism interposed between the bridge and the input part of the governor lever. The above-mentioned pieces are brought into contact with one race in a surface contact manner and are interlocked, the other race is fixed to and supported by a swinging tool, and the swinging tool is pivotally supported on the input part of the governor lever so as to be able to swing freely. Therefore, the intermediate transmission mechanism is supported only by the governor lever.
以下、本発明の一実施例を図面に基き説明す

心式のガバナ７が取付けられる。 This governor device 1 has a rotating shaft (crankshaft) that is pivotally supported on the crankcase 4 inside a gear case 4 formed on the front side of a crankcase 3 of an engine 2.
A crank gear 6 is attached to the shaft end 5a, and a centrifugal governor 7 is attached to the front surface of the crank gear 6.

る。 The governor 7 consists of a governor base 8 attached to the front surface of the crank gear 6, and a governor weight 10 pivotably supported on a bracket 9 protruding from the governor base 8. The output portion 10a of the governor weight 10 is pivoted here. The governor force of the governor weight 10 is transmitted to the governor lever 12 from a movably supported piece 11 via an intermediate transmission mechanism 13 supported only on the input portion 12a of the governor lever 12.

ある（第２図及び第３図参照）。 The intermediate transmission mechanism 13 includes a swinging tool 14 pivotably supported on the input portion 12a at the tip of the governor lever 12.
and a rolling bearing (radial ball bearing) 15 in which an inner race 15a is fitted and supported by the swinging tool 14. It is brought into contact with the outer race 15b (see FIGS. 2 and 3).

プである。 In addition, the reference numeral 16 in the figure is a governor spring placed between the governor race 12 and the speed regulating lever 17, and the reference numeral 18 is the balance between the governor spring 16 set by the speed regulating lever 17 and the governor force of the governor 7. This is a fuel injection pump that adjusts the amount of fuel injected depending on the situation.
上記のように構成したガバナ装置１の作用を次

５ａから揺動具１４を介してガバナレバー１２の
入力部１２ａに伝えられる。 As the crankshaft 5 rotates at high speed, the governor weights 10, 10 centrifugally swing, and the centrifugal force is transmitted to the outer race 15b of the rolling bearing 15 via the piece 11 of the output part 10a, and the inner race 1
5a, the signal is transmitted to the input section 12a of the governor lever 12 via the swinging tool 14.

収する。 At this time, the output part 10a of the governor weight 10
oscillates while rotating along with the crankshaft 5,
The rotational component of the crankshaft 5 is absorbed by the outer race 15b and inner race 15a of the rolling bearing 15 provided between the input portion 12a of the governor lever 12 and prevents the rotational component from being transmitted to the input portion 12a of the governor lever 12. . Further, when the swinging force of the governor weight 10 is applied unevenly to the intermediate transmission mechanism 13, the intermediate transmission mechanism 13 swings freely to absorb stress in directions other than the axial direction of the crankshaft 5.
本発明は、上記のように構成され、作用するこ
とから、次の効果を奏する。 Since the present invention is configured and operates as described above, it has the following effects.
イ 第１に、ガバナウエイトの出力部に揺動自在

するところがり軸受のレースが自由に回転して
追随し、駒とレースとの接当面は常に一緒に進
退移動するものであつて摺動しないので、摺動
抵抗が生じない。First, as the piece that is swingably supported on the output part of the governor weight swings, the race of the rolling bearing that comes into contact with the piece rotates freely and follows, causing the contact between the piece and the race. For the time being, they always move forward and backward together and do not slide, so no sliding resistance occurs.

かに小さくなる。 Second, the relative rotation between the governor weight and the governor lever is absorbed by the rolling rotation of the rolling bearing, and the sliding rotation of the abutting part A between the governor shaft and governor lever of the conventional product shown in Fig. 4 is absorbed by the rolling rotation of the rolling bearing. The rotational resistance is much smaller than that absorbed by

摺動部を無くすことができて、従来品における
摺動部での摺動抵抗を無くせるうえ、その摺動
部でのこじれによる抵抗をも無くせる。 Thirdly, the intermediate transmission mechanism is composed of a rolling bearing and a swinging tool, and the swinging tool is swingably pivoted to the input part of the governor lever, so that the intermediate transmission mechanism is supported only by the governor lever. Even if the rocking force is applied unevenly to the intermediate transmission mechanism, it can be freely rocked and absorbed, and the governor shaft of the conventional product shown in FIG. 4 is not required. This eliminates the sliding part between the governor shaft and the engine rotating shaft, which eliminates the sliding resistance at the sliding part in conventional products, and also eliminates the resistance due to twisting at the sliding part.

バナ装置の応答感度及び精度を高めることがで
きる。 Therefore, the motion resistance generated in the transmission system from the governor weight to the governor lever can be made much smaller than in the conventional product shown in FIG. 4, so that the response sensitivity and accuracy of the governor device can be improved.
ロ 第１に、ガバナウエイトの出力部に揺動自在
に枢支した駒ところがり軸受のレースとの接当
面は、摺動しないので摩耗しない。(b) First, the piece that is swingably supported on the output part of the governor weight and the contact surface with the race of the rolling bearing do not slide, so they do not wear out.
第２に、ガバナウエイトとガバナレバーとの
間の相対回転を吸収するころがり軸受は、ころ
がるだけで摺動しないので、摩耗しにくい。 Second, the rolling bearing that absorbs the relative rotation between the governor weight and the governor lever only rolls and does not slide, so it is less likely to wear out.
