Abstract
Description
また、第1、第2などの序数を含む用語は多様な構成要素を説明するために用いられるが、この用語は一つの構成要素を他の構成要素から区別する目的でのみ用いられ、この用語によって構成要素が限定されるものではない。
以下、図面を参照して、第1実施形態に係る偏心揺動型減速装置10の構成について説明する。図1は、第1実施形態の偏心揺動型減速装置10を示す側面断面図である。本実施形態の偏心揺動型減速装置10は、内歯歯車と噛み合う外歯歯車を揺動させることで、内歯歯車及び外歯歯車の一方の自転を生じさせ、その生じた運動成分を出力部材から被駆動装置に出力する偏心揺動型減速装置である。
hm=(Ae・Vw)/(Vc・60・1000)・・(1)
(但し、hmは平均切り粉厚み[mm]、Aeは砥石82のストローク当たりの切込量[mm]、Vwはワーク81の送り速度[mm/min]、Vcは砥石82の周速Vc[m/s]である。)
次に、図8を参照して、第2実施形態に係る偏心揺動型減速装置10の構成について説明する。第2実施形態の図面および説明では、第1実施形態と同一または同等の構成要素、部材には、同一の符号を付する。第1実施形態と重複する説明を適宜省略し、第1実施形態と相違する構成について重点的に説明する。図8は、第2実施形態の偏心揺動型減速装置10を示す側面断面図であり、図1に対応する。
32・・内ピン、 70・・入力歯車。
