Description
小径円弧部のトラバース回数の減少化を図ることができ、加工能率の向上を図って、全体としての加工時間の短縮化を達成できる。
全体加工(転走面全体の加工)のみと、全体加工(転走面全体の加工)と中央部加工(転走面の大径円弧部の加工)とを行った場合における、面粗度と加工時間等を比較した。この場合、外径寸法が50〜80mmのサイズで、転走面角度27°、転走面幅14mmの円すいころ軸受の外輪を用いた。図4(a)は全体加工のみの場合、図4(b)は全体加工と中央部加工の場合のそれぞれの転走面の軸方向中央部の面粗度を示している。
(全体加工+中央部加工)の加工で、タリータイムなしとタリータイム有とで面粗度と加工時間等を比較した。外径寸法が50〜80mmのサイズで、テーパ角度44°、転走面幅13mmの円すいころ軸受の外輪を用いた。ここで、タリータイムとは、転走面Rの軸方向全体の加工中に、小径円弧部41a、41bの端部位置で砥石50のトラバース動作を停止する時間のことで、タリータイムなしとは、この停止する時間を有さない場合であり、タリータイム有とは停止する時間を有する場合である。

13,23,33 外輪
40 大径円弧部
41a,41b 小径円弧部
50(50A、50B、50C) 砥石
Claims (7)
