摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing, in which a lubricating life can be simply extended, thus attaining labor saving in maintenance with the bearing unassembled. SOLUTION: As shown in (A), in an initial status, a fluid pressure cylinder part 21 is closely filled up with operation grease G H . When the operation grease G H flows into a fluid pressure cylinder part 21, the internal pressure in a cylinder chamber 21b increases, and also fluid pressure applied to a receiving part 21d of a piston part 21c increases. Therefore, the piston part 21c starts to advance into the cylinder chamber 21b, the piston part 21c presses an extension part 19e to transmit driving force, and the movable member 19 starts to move in a direction separating from the bearing 12. As a result, as shown in (B), grease G O after deterioration moves together with the movable member 19 in a state retained in a retainer 19a, and a gap between the tip surface of the retainer 19a and the end surface of the bearing 12 is gradually filled up with non-deteriorated grease G N .

摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing, in which the lubricating life can be simply extended to save labor in maintenance with the bearing unassembled. SOLUTION: As shown in (A), in an initial status a fluid pressure operation chamber 20 is closely filled up with operation grease G H . As shown in (B), when exchanging the grease, the operation grease G H is injected into a passage 23, and passes through a passage 24 from the passage 23, and the operation grease G H flows into the fluid pressure operation chamber 20. As the injection amount of the operation grease G H increases, the internal pressure in the fluid pressure operation chamber 20 increases, and the fluid pressure applied to a pressure receiving part 19b of a movable member 19 also increases, so that the movable member 19 starts to move in a direction separating from the bearing 12. As a result, deteriorated grease G O is moved together with the movable member 19 in a state of being retained in a retainer 19a, and a gap between the tip surface of the retainer 19a and the end surface of the bearing 12 is gradually filled up with non-deteriorated grease G N .

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.
