Description
この発明による転がり軸受は、内輪、外輪、両輪間に配置された複数の転動体および両輪端部間に配置された非接触シールを有している転がり軸受において、内輪端部に設けられて非接触シールの内径側縁部を収容するシール収容溝の軸方向内側の側面が、径方向の内方にいくにしたがって軸方向の外方に傾斜する傾斜面とされるとともに、非接触シールに、シール収容溝の傾斜面に対向してのびる傾斜面を有するリップ部が設けられており、リップ部の先端径は、内輪の外径よりも小さい径とされるとともに、リップ部先端とシール収容溝の傾斜面との間の隙間をＣ、リップ部径方向内方端とシール収容溝の傾斜面との間の隙間をＢとして、Ｃ＞Ｂとされていることを特徴とするものである。 A rolling bearing according to the present invention is a rolling bearing having an inner ring, an outer ring, a plurality of rolling elements disposed between both wheels, and a non-contact seal disposed between both wheel end portions. The side surface on the inner side in the axial direction of the seal housing groove that accommodates the inner diameter side edge portion of the contact seal is an inclined surface that is inclined outward in the axial direction as it goes inward in the radial direction. A lip portion having an inclined surface extending opposite the inclined surface of the seal housing groove is provided, and the tip diameter of the lip portion is smaller than the outer diameter of the inner ring, and the tip of the lip portion and the seal housing groove C> B, where C is the gap between the inclined surface and B, and B is the gap between the radially inner end of the lip portion and the inclined surface of the seal housing groove .

The axially inner side surface of the seal housing groove provided at the inner ring end portion for accommodating the inner side edge of the non-contact seal is an inclined surface that inclines outward in the axial direction as it goes inward in the radial direction. In addition, the non-contact seal is provided with a lip portion having an inclined surface facing the inclined surface of the seal housing groove, and the tip diameter of the lip portion is smaller than the outer diameter of the inner ring. C> B, where C is the gap between the tip of the lip portion and the inclined surface of the seal housing groove, and B is the gap between the radially inner end of the lip portion and the inclined surface of the seal housing groove .
