歯車１を軸２に取り付けることを得る。In the above explanation, the bolt 4 was used to remove the gear, but after screwing in the bolt 4 firmly to push open the annular groove and finishing the shaft hole 1a, it is inserted into the desired shaft 2. , also by removing this bolt 4, it is possible to attach this gear 1 to the shaft 2.
このような取付は方法に依るときは、部品が軸に組み付
けられた状態ては、余分な部品が一切付いていないこと
になり、極めてスマートで、慣性モーメントか少なく、
安全かつ確実な取付けが可能となるものである。Depending on the method of installation, when the parts are assembled on the shaft, there are no extra parts attached, which makes it extremely smart and reduces the moment of inertia.
This enables safe and reliable installation.
