Description
【考案の詳細な説明】
この考案は、エンジンの回転を他に伝えるために、スプ
ロケットやプーリ等の駆動輪を取着するクランク軸の駆
動輪取着装置の改良に関する。[Detailed Description of the Invention] This invention relates to an improvement of a drive wheel attachment device for a crankshaft to which a drive wheel such as a sprocket or pulley is attached in order to transmit engine rotation to other parts.
クランク軸の一端にプーリ等の駆動輪とフライホイール
マグネトを取着する場合、通常は第１図に示すように、
クランク軸Ａの段部Ｂに衝合するように駆動輪Ｃを挿通
してキーＤによって回り止めし、クランク軸ＡのネジＥ
にナツトＦを螺合して駆動輪Ｃを固定する。When attaching a drive wheel such as a pulley and a flywheel magneto to one end of the crankshaft, normally, as shown in Figure 1,
Insert the drive wheel C so that it abuts against the stepped portion B of the crankshaft A, lock it with the key D, and screw the screw E of the crankshaft A.
Fix the drive wheel C by screwing the nut F into the .
そして、その外側のテーパ部ＧにフライホイールＨを挿
入して、ナツトＫによって取着している。A flywheel H is inserted into the outer tapered portion G and is attached with a nut K.
このような構造では、クランク軸Ａの太さを徐々に変え
る必要があり、根元のベアリング部分が太くなって、重
くなる。In such a structure, it is necessary to gradually change the thickness of the crankshaft A, and the bearing portion at the base becomes thicker and heavier.
又、クランク軸ＡにネジＥを加工しなければならないの
で、製造コストも高くなる。Furthermore, since the screw E must be machined on the crankshaft A, the manufacturing cost also increases.
この考案は、かかる点に鑑み改善したもので、以下第２
図に示す本考案の実施例について説明する。This idea has been improved in view of these points, and is described below as part 2.
An embodiment of the present invention shown in the figures will be described.
エンジンのクランク軸１には、段部２とテーパ部３を設
ける。A crankshaft 1 of an engine is provided with a stepped portion 2 and a tapered portion 3.
プーリ等の駆動輪４は、芯孔をクランク軸１に挿通して
、段部２に衝合させ、キー５によって回り止めする。A drive wheel 4 such as a pulley has a core hole inserted through the crankshaft 1, is brought into contact with the stepped portion 2, and is prevented from rotating by a key 5.
テーパ部３には、フライホイールマグネトロを挿入し、
ナツト７を螺合して取着する。Insert the flywheel magnetro into the tapered part 3,
Attach by screwing together nut 7.
そして、フライホイールマグネトロを取着するとき、駆
動輪４とフライホイールマグネトロの間にバネ体８を介
在させ、バネ体８で、駆動輪４を段部２に押付けて固定
する。When the flywheel magneto is attached, a spring body 8 is interposed between the drive wheel 4 and the flywheel magneto, and the spring body 8 presses and fixes the drive wheel 4 against the stepped portion 2.
バネ体８は、図では、コイル状バネであるが、皿バネの
ようなものでもよい。Although the spring body 8 is a coiled spring in the figure, it may be a disc spring.
９はベルト、１０はベアリング、１１はオイルシール、
１２はクランクケースである。9 is a belt, 10 is a bearing, 11 is an oil seal,
12 is a crankcase.
作用について説明する。The effect will be explained.
クランク軸１の段部２に、駆動輪４がバネ体８で押付け
られ、キー５によって回り止めされて、駆動輪４が固定
できる。The drive wheel 4 is pressed against the stepped portion 2 of the crankshaft 1 by a spring body 8, and is prevented from rotating by a key 5, so that the drive wheel 4 can be fixed.
そして、クランク軸１は、段部２だけ異径であればよく
、全体として細くなるこれに伴って、ベアリング１０や
オイルシール１１も小さくでき、軽量で安価になる。The crankshaft 1 only needs to have a different diameter at the stepped portion 2, and as the crankshaft 1 becomes thinner as a whole, the bearing 10 and oil seal 11 can also be made smaller, making it lighter and cheaper.
又、クランク軸１の形状も簡単になって、加工が容易に
なる。Furthermore, the shape of the crankshaft 1 is simplified, making processing easier.
以上説明したように、この考案は、クランク軸の段部に
衝合させて駆動輪を挿入してキーによって回り止めし、
クランク軸の端部にフライホイールマグネトを挿入して
螺着するに当り、駆動輪とフライホイールマグネトの間
にバネ体を介在させて駆動輪を固定したので、クランク
軸の形状が簡単になって安価になり、クランク軸の段部
も一つでよいので、根元部が細くでき、これに伴って、
ベアリングやオイルシールも小径にできて、軽量で安価
にできる。As explained above, this idea involves inserting the drive wheel against the stepped part of the crankshaft and preventing it from rotating with a key.
When inserting and screwing the flywheel magnet into the end of the crankshaft, a spring body was interposed between the drive wheel and the flywheel magnet to secure the drive wheel, making the shape of the crankshaft simpler. It is cheaper, and only one stepped part of the crankshaft is required, so the base can be made thinner, and along with this,
Bearings and oil seals can also be made smaller in diameter, making them lighter and cheaper.
又、駆動輪は、圧入のように強い力が加わらないので、
焼結合金等で安価に製作できる。Also, since strong force is not applied to the drive wheel as with press-fitting,
It can be manufactured at low cost using sintered alloy, etc.
