- 共通回転軸(18)の周りで相対的に回転運動可能な2つの構成部材(12、16)の間における隙間を密封するための、第1構成部材(12)に固定配置されて第2構成部材(16)の密封表面(32)と相互作用するブラシ・シール(22)を有する密封構造(10)であって、密封表面(32)が円錐状の形状を呈し、少なくとも1つの構成部材(12または16)が軸方向に変位可能であり、他の構成部材(16または12)に対して調節可能であり、
軸方向変位および調節のための手段(34,36,38)が、前記1つの構成部材(12)と前記1つの構成部材(12)を包囲するケーシング(14)との間に備えられていて、
前記1つの構成部材(12)が調節のため軸方向に変位されるとき、ブラシ・シール(22)は第2構成部材(16)の円錐状の密封表面(32)に対して軸方向に相対変位され、ブラシ・シール(22)が第2構成部材(16)の円錐状の密封表面(32)との密封された接触を維持しつつ、第1構成部材(12)のブラシ・シール(22)の固定部分と第2構成部材(16)の円錐状の密封表面(32)との間の隙間を変化させることを特徴とする密封構造。 - 上記手段が、滑りシート(38)と、ケーシング(14)にはめ込まれた調節ナット(34)と、前記1つの構成部材(12)に切り込まれた変位ねじ山(36)とを含むことを特徴とする、請求項1に記載の密封構造。
