摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing, in which a lubricating life can be easily extended and labor saving in maintenance can be achieved while the bearing remains in an unassembled condition.SOLUTION: Guide parts 19c, 19d movably guide a movable part 19. The guide part 19c is movably guided in an inner circumferential part of a wall part 14g, while the guide part 19d is movably guided in an inside inner circumferential part of a bearing cap 14. The guide parts 19c, 19d are cylindrical guide surfaces centering the center axis of the bearing cap 14, allowing the movable part 19 to move in the center axis direction of the bearing cap 14. The guide parts 19c, 19d prevent the movable part 19 from tilting when the movable part 19 moves in a filling chamber. As a result, generation of excessive frictional force between the guide parts 19c, 19d and the filling chamber of the bearing cap 14 can be prevented, and the movable part 19 can be smoothly moved upon replacing and supplying grease.

摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing which can extend a lubrication life and save work in maintenance.SOLUTION: When an opening/closing part 22 is loosened to open a supply/discharge port 21a, a fluid in a bag body 20 is discharged to the outside from the supply/discharge port 21a through piping 21. As a result, an internal pressure of the bag body 20 decreases to shrink the bag body 20 and to increase a volume of an annular filling chamber 14b, forming a space Sbetween the chamber and a bearing 12. When the opening/closing part 22 is fastened to close the supply/discharge port 21a and further a new grease Gis injected through a flow passage 16d, the new grease Gis made to pass through the bearing 12 and fed to an annular filling chamber 14b on a side close to a bearing lid 14. As a result, an old grease Ginside the annular filling chamber 14b and a degraded grease inside the bearing 12 are pushed and expelled to a bottom of the annular filling chamber 14b, while the new grease Gis intermediately supplied to replenish to the space Sbetween the old grease Ginside the annular filling chamber 14b and the bearing 12.

摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing enabling labor saving in maintenance by easily elongating a lubrication life without the bearing disassembled.SOLUTION: A fluid pressure cylinder part 21 transmits driving force to a movable part 19 through a piston part 21c and drives the movable part 19 by driving an extension part 19e. The fluid pressure cylinder part 21 generates driving force outside a filling chamber 14a and transmits the driving force from outside of the filling chamber 14a to the movable part 19. Thus, with the fluid pressure cylinder 21 part separated from the filling chamber 14a, fluid pressure of grease Gfor operation can be applied to the fluid pressure cylinder part 21. As a result, outflow of the grease Gfor operation from the fluid pressure cylinder part 21 to the filling chamber 14a can be prevented, and outflow of grease G from the filling chamber 14a to the fluid pressure cylinder part 21 can be also prevented.
摘要翻译：要解决的问题：为了提供轴承的润滑结构，能够通过在不拆卸轴承的情况下容易地延长润滑寿命来节省维护。解决方案：流体压力缸部分21通过活塞部分21c将驱动力传递到可移动部分19，并通过驱动延伸部分19e来驱动可动部分19。流体压力缸部21在填充室14a的外侧产生驱动力，并将驱动力从填充室14a的外部传递到可动部19.因此，在与填充室14a分离的流体压力缸21的部分，的润滑脂G H 可以应用于流体压力缸部21.结果，润滑脂G H SB 可以防止从流体压力缸部21到填充室14a的动作，并且也可以防止润滑脂G从填充室14a流出到流体压力缸部21。版权所有（C）2013，JPO＆INPIT
