【考案の詳細な説明】
本考案は、内燃機関における潤滑油ポンプに関するもの
である。[Detailed Description of the Invention] The present invention relates to a lubricating oil pump for an internal combustion engine.
内燃機関の潤滑ポンプは、通常は、機関のクランク軸等
から回転力を取出し、これによって駆動されるようにな
っている。A lubrication pump for an internal combustion engine is normally driven by extracting rotational force from the engine's crankshaft or the like.
したがって、この形式によるときはクランク軸に歯車等
を取付け、該歯車に噛合う別の歯車を用意する必要があ
り、それだけ部品数が増え、またそれに伴うスペースも
必要であるという不都合な点がある。Therefore, when using this type, it is necessary to attach a gear etc. to the crankshaft and prepare another gear to mesh with the gear, which has the disadvantage of increasing the number of parts and requiring space accordingly. .
本考案は、このような不都合を解消したものであって、
内燃機関に設けられているガバナ装置のガバナ軸を潤滑
油ポンプの駆動軸に兼用させたものである。The present invention solves these inconveniences, and
The governor shaft of the governor device provided in the internal combustion engine is also used as the drive shaft of the lubricating oil pump.
従来の装置ではガバナ軸の端部は遊んでいるが、本考案
にあってはこれが有効に利用されるため、部品数、スペ
ース等を少くすることができるものである。In conventional devices, the end of the governor shaft has some looseness, but in the present invention, this is effectively utilized, so the number of parts, space, etc. can be reduced.
以下図面により本考案の実施例を説明する。Embodiments of the present invention will be described below with reference to the drawings.
１はガバナ軸であって、ポンプの駆動軸を兼ねている。Reference numeral 1 denotes a governor shaft, which also serves as a drive shaft for the pump.
ガバナ軸１には、機関の回転を伝える歯車２が固着され
ていて、ガバナ軸１は機関の回転数と同速（又はこれと
比例した速度）で回転する。A gear 2 that transmits the rotation of the engine is fixed to the governor shaft 1, and the governor shaft 1 rotates at the same speed as (or at a speed proportional to) the rotation speed of the engine.
さらに、ガバナ軸１には遠心重錘３、シフタ４等のガバ
ナ部品が取付けられている。Furthermore, governor parts such as a centrifugal weight 3 and a shifter 4 are attached to the governor shaft 1.
ガバナ軸１のガバナ部分と反対側（図面における左側）
には、回転式ポンプ５が取付けられている。The side opposite to the governor part of governor shaft 1 (left side in the drawing)
A rotary pump 5 is attached to the .
即ち、６は回転式ポンプのケーシングで、一端は機枠７
に固着しており、該ケーシング６の中実軸受部８を貫通
してガバナ軸１は延びている。That is, 6 is the casing of the rotary pump, and one end is the machine frame 7.
The governor shaft 1 extends through the solid bearing portion 8 of the casing 6.
９はガバナ軸１に固着した外歯歯車１０は内歯歯車であ
って、両歯車により共やく歯車が構成される。An external gear 9 fixed to the governor shaft 1 is an internal gear, and both gears together constitute a gear.
そしてケーシング６、機枠７、外歯歯車９、および内歯
歯車１０とによって回転ポンプは形式される。The casing 6, machine frame 7, external gear 9, and internal gear 10 form a rotary pump.
なお１１は外歯歯車９をガバナ軸１に取付けるピン、１
２は吸油口、１３は排油口をそれぞれ示すものである。Note that 11 is a pin for attaching the external gear 9 to the governor shaft 1;
2 indicates an oil intake port, and 13 indicates an oil drain port.
したがって、本考案装置は次のごとく作動する。Therefore, the device of the present invention operates as follows.
即ち、ガバナ軸１の回転によりガバナ重錘３が揺動して
シフタ４を作動することにより調速作用が行われる。That is, the rotation of the governor shaft 1 causes the governor weight 3 to swing and actuate the shifter 4, thereby performing speed regulating action.
一方潤滑油ポンプである回転ポンプはガバナ軸と同軸上
に装備されているのでガバナ軸１が回転すると外歯歯車
９が回転して潤滑油を吸油口１２から吸入して排油口１
３に送油することか゛できる。On the other hand, the rotary pump, which is a lubricating oil pump, is installed coaxially with the governor shaft, so when the governor shaft 1 rotates, the external gear 9 rotates, sucking lubricating oil from the oil intake port 12, and draws the lubricating oil from the oil drain port 1.
It is possible to send oil to 3.
内燃機関の機枠とガバナ装置との間の狭いスペースにお
いて、このガバナ装置のガバナ軸の遊端を上記機枠近く
まで延長し、これに共やく歯車を取付け、この共やく歯
車を取囲むように形成したケーシングを前記機枠に取付
けることにより回転ポンプを形成し、上記ガバナ軸の回
転力によって潤滑油を加圧するようにしたから、ガバナ
装置と機枠との間の狭いスペースに潤滑油を圧送する回
転ポンプを装着することができて機関の容積を小さくす
ることができるのは勿論、潤滑油ポンプを駆動するため
の動力源を別個に機関から取出す必要がなくなり、それ
だけ機関の部品数を省略でき、構造を簡単化することが
できるので、極めて安価に潤滑油ポンプを機関に取付け
ることができ、その実用的な効果は著しく大である。In a narrow space between the machine frame of an internal combustion engine and the governor device, the free end of the governor shaft of the governor device is extended close to the machine frame, a gear is attached to this, and a gear is attached to the free end so as to surround the gear. A rotary pump is formed by attaching a casing formed in the form of Not only can the volume of the engine be reduced by attaching a rotary pump for pressure-feeding, but it also eliminates the need to separately take out the power source for driving the lubricating oil pump from the engine, which reduces the number of parts in the engine. Since the lubricating oil pump can be omitted and the structure can be simplified, the lubricating oil pump can be attached to the engine at an extremely low cost, and its practical effects are extremely large.
