Abstract
Description
ことを特徴とする。
ことを特徴とする。
ここで、2つの部材同士を摺動させたとき「凝着摩耗」が発生する場合、その部材が形成される素材を同種素材という。また、「異種素材」とは同種素材でない素材をいい、すなわち2つの部材同士を摺動させたとき「凝着摩耗」が発生しない場合には、一方の部材の素材に対して他方の部材の素材が異種素材に相当する。異種素材の例としては、例えば任意の素材を金属、樹脂、セラミック、ガラス等のカテゴリーに分類したとき、カテゴリー違いの素材同士が相当する。また、「軸線方向」とは、ここでは弁本体の軸線方向をいうものとする。
図1は、本実施の形態にかかる電動弁を示す全体縦断面図である。図2は、図1に示す電動弁に用いられている遊星ギヤ式減速機構を分解して示す斜視図であるが、理解しやすいように一部をカットして示している。図3は、図2に示す遊星ギヤ式減速機構の遊星ギヤとキャリヤを分解して示す斜視図である。
図5は、別な実施の形態にかかる電動弁のキャン内部の断面図である。本実施の形態においては環状体が用いられておらず、その代わりとして太陽ギヤ41のボス41aに摺動する摺動部材は、出力軸46(図5にハッチングで示す)が兼ねている。つまり、出力軸46の上端部が摺動部材として機能している。
