摘要： PROBLEM TO BE SOLVED: To offer a lubricating structure of a bearing wherein a lubrication life can be extended and can attain a labor saving in maintenance. SOLUTION: When an opening and closing part 22 is loosened, and a feed and an exhaust port 21a is released; a fluid inside a bag body is exhausted outside from a feed and an exhaust port 21a passing through piping 21. Resultantly, an internal pressure of the bag body 20 falls off and the bag body 20 contracts, a volume of an annular filling room 14b becomes large, a space S N1 is formed with a bearing 12. When the opening and closing part 22 is closed and the feed and exhaust port 21a is closed, and when a new grease G N is impregnated through a passage 16d; this new grease passes the bearing 12 and is sent out to an annular filling room 14b by the side of a bearing lid 14. Resultantly, an old grease G O inside the annular filling room 14b and a degrading grease inside a bearing 12 are pushed away and got away to a bottom of an annular filling room, and to the space S N1 between an old grease G O inside the annular filling room 14b and a bearing 12, a new grease G N is intermediately fed and supplied.

摘要： PROBLEM TO BE SOLVED: To provide a lubrication structure of a bearing capable of saving labor for maintenance by extending lubrication life. SOLUTION: As shown in (A), grease G is filled between an annular filling chamber 14b and a movable plate 20 in the initial state. When a bearing 12 rotates in this state, the grease G in the vicinity of an end surface of the bearing 12 is gradually deteriorated, and wear powder and the like are mixed in the grease G in the vicinity of the end surface of the bearing 12. As shown in (B), when the movable plate 20 starts to move in a direction separating from the bearing 12 in replacing grease, the deteriorated grease G O moves along with the movable plate 20 in a state held to a holding part 21, and non-deteriorated grease G N is pressed by the movable plate 20. Thereby, the non-deteriorated grease G N flows into a guide opening 28 from an inflow opening 27, and is spouted out from a discharge opening 29, and the non-deteriorated grease G N is filled between a tip surface of the holding part 21 and an end surface of the bearing 12.
