密封軸受

Sealed bearing

Abstract

<P>PROBLEM TO BE SOLVED: To provide a sealed bearing which has a long service life and can prolong a checking period for maintenance and inspection. <P>SOLUTION: A pair of sealing covers 16 are attached to both sides of a cylindrical roller bearing 11 having an outer race 12 and an inner race 13. The sealing cover 16 has an annular grease reservior 19. The grease reservior 19 is partitioned by means of a plurality of partitions 20 into a plurality of grease filling chambers 21 and a plurality of unfilling chambers 22. A plurality of the grease filling chambers 21 are filled with grease in order to increase the retained quantity of the grease, and to prolong the service life the cylindrical roller bearing 11 by lubricating the inside of the cylindrical roller bearing 11 for a long time. It is intended to elongate the checking period for maintenance and inspection by supplying grease into the unfilling chambers 22 in the midterm between the checking periods. <P>COPYRIGHT: (C)2005,JPO&NCIPI
【課題】軸受寿命が長く、保守、点検の検査期間の延長を図ることができる密封軸受を提供することである。 【解決手段】外輪12と内輪13間に組込まれた円筒ころ軸受11の両側に一対の密封カバー16を取付ける。密封カバー16に環状のグリース溜り19を設け、そのグリース溜り19を複数の仕切り部20によって複数のグリース封入室21と複数のグリース未封入室22とに仕切り、複数のグリース封入室21にグリースを充填してグリース保持量の増大を図り、円筒ころ軸受11の内部を長期にわたって潤滑できるようにして円筒ころ軸受11の寿命向上を図る。グリース未封入室22にグリースを中間給脂して保守、点検期間の検査期間の延長を図る。 【選択図】 図2
