Abstract
Description
また、特許文献2に記載のアイドラプーリにおいても、転がり軸受へのダスト侵入を確実に防止するため、外周部がベアリングを覆い隠すように断面C字形に湾曲せしめた円板状の板材が設けられ、プーリの内側リング部の外側面に可撓性シール材を板材と支持体の張出部とに接触させたものが知られている。
(1) 外輪の周囲にプーリが設けられた転がり軸受の軸方向側方に配置され、前記転がり軸受の軸受空間を覆うプーリユニット用ダストカバーであって、
前記転がり軸受と軸方向で対向する円板部には、波状部が形成されることを特徴とするプーリユニット用ダストカバー。
(2) 前記波状部は、少なくとも前記外輪と軸方向で対向する部分に形成されており、且つ、前記外輪及び軸受シールと接触しないことを特徴とする(1)に記載のプーリユニット用ダストカバー。
(3) (1)又は(2)に記載のプーリユニット用ダストカバーを備えることを特徴とするプーリユニット。
たとえば、上記実施形態では、転がり軸受12の内輪14が直接ボルト20に外嵌されるように構成されていたが、これに限らず、内輪14は環状の支持体などを介してボルト20に固定されてもよい。
たとえば、ダストカバー30の波状部32は、図3(a)に示すように、軸方向頂部を尖らせたものや、図3(b)に示すように、軸方向頂部に平面を有する形状であってもよい。
