【考案の詳細な説明】
産業上の利用分野
この考案は、軸嵌合における軸穴を有する軸に
関するものであり、軸穴加工を容易にする構造を
提供するものである。[Detailed Description of the Invention] Industrial Application Field This invention relates to a shaft having a shaft hole in shaft fitting, and provides a structure that facilitates shaft hole machining.
従来技術及びその問題点
従来、軸を嵌合してキーで固定するための軸穴
加工は、第５図に示すように、キー溝１を有する
軸嵌合部２、キー溝逃し部３とも旋盤加工による
か、若しくは第６図に示すように、軸嵌合部２′
のみ旋盤加工とし、キー溝逃し穴３′をドリル加
工により行い、キー溝１′はスロツター加工によ
り行つていた。Conventional technology and its problems Conventionally, shaft hole machining for fitting a shaft and fixing it with a key involves a shaft fitting part 2 having a keyway 1 and a keyway relief part 3, as shown in FIG. The shaft fitting part 2' may be formed by lathe processing or as shown in FIG.
The keyway escape hole 3' was formed by drilling, and the keyway 1' was formed by slotter processing.
このため、キー溝逃し部旋盤加工は切粉の排除
が困難であり、又キー溝のスロツター加工は加工
能率が悪いという問題があつた。 For this reason, lathe machining of the keyway relief part makes it difficult to remove chips, and slotter machining of the keyway has the problem of poor machining efficiency.
問題点を解決するための手段及び作用
この考案は、軸嵌合のための軸穴を有する軸を
製作するに際し、中実部と貫通キー溝を形成した
軸穴部を別体として製作し、その突合せ部を溶
接、溶着又は接着により一体化することにより前
記問題点を解決した。Means and Effects for Solving the Problems This invention, when manufacturing a shaft having a shaft hole for shaft fitting, separately manufactures a solid part and a shaft hole part in which a through keyway is formed, The above problem was solved by integrating the butt portions by welding, welding, or adhesion.
軸穴部は貫通キー溝と貫通穴を有するように製
作すればよいから、加工が極めて容易になる。 Since the shaft hole portion may be manufactured to have a through keyway and a through hole, machining becomes extremely easy.
実施例
第２図に示す中実部１０を旋盤加工により製作
した後、別加工により製作した第３図の軸穴部２
０を圧入し、突合せ部３０を第１図に示すよう
に、溶接、溶着又は接着することにより一体とす
る。符号２１が貫通キー溝である。Example After the solid part 10 shown in Fig. 2 was manufactured by lathe processing, the shaft hole part 2 shown in Fig. 3 was manufactured by separate processing.
0 is press-fitted, and the abutting portion 30 is integrated by welding, welding, or gluing as shown in FIG. Reference numeral 21 is a through keyway.
その後、第４図に示すように、軸穴２２と加工
時芯出しされたＹ部と、中実部センタ穴Ｘ部を基
準として、外周部の研削加工を行う。これにより
研削部に対する軸穴の振れは実用上さしつかえの
ない値になる。 Thereafter, as shown in FIG. 4, the outer circumferential portion is ground using the shaft hole 22, the Y portion centered during machining, and the solid portion center hole X portion as a reference. As a result, the run-out of the shaft hole relative to the grinding part becomes a value that is acceptable for practical purposes.
考案の効果
軸を中実部と軸穴部に分割し別加工を行うた
め、キー溝加工と軸穴加工が容易となり加工能率
が上がる。Effects of the invention: Since the shaft is divided into the solid part and the shaft hole part and processed separately, keyway machining and shaft hole machining become easier and machining efficiency increases.
軸穴部として焼結合金を採用することによりよ
り効果は顕著となる。 The effect becomes more pronounced by using a sintered alloy for the shaft hole.
