- the greasing mechanism 1 includes a display member 13 having a specific gravity smaller than that of grease in the greasing pipe 10.
- the display member 13 is provided at a predetermined first position in the greasing pipe 10 filled with grease.
- the shape of the display member 13 is arbitrary. Since the grease is semi-solid, the display member 13 having a specific gravity smaller than the specific gravity of the grease does not move in the greasing pipe 10 filled with the grease. However, since the grease flows when a force exceeding a certain level is applied, the grease and the display member 13 move in the grease supply pipe 10 when the grease is supplied by the grease gun.
- a display window 14 is provided in a part of the greasing pipe 10 including the second position.
- the display window 14 is formed of a member that transmits at least part of visible light, and the movement of the display member 13 provided inside the greasing tube 10 can be visually recognized from the outside of the greasing tube 10. For example, when the maintenance staff looks at the display window 14 and the display member 13 is in the first position as shown in FIG. 2, it can be determined that the lubrication is not being performed.
- the greasing mechanism 1 includes a holding portion 15 having a shape that stops the display member 13 that moves in the greasing direction by the pressure of grease during greasing at a second position.
- FIG. 3 is a cross-sectional view of the greasing mechanism according to the embodiment.
- FIG. 3 is a cross-sectional view taken along line AA of the greasing mechanism 1 shown in FIG.
- the greasing pipe 10 is closed at one end and provided with a greasing port at the other end, and has a first pipe 17 having an opening 16 on a side surface along the greasing direction, and one end at the ball bearing 7 or the roller bearing 8. And a second pipe 18 connected at the other end to the opening 16 of the first pipe 17.
- the greasing pipe 10 includes one first pipe 17 and one second pipe 18.
- the holding portion 15 is a part of the first tube 17 including the closed end of the first tube 17.
- maintenance part 15 stops the display member 13 which moves at the time of greasing at the closed end of the 1st pipe
- the opening 16 is provided at a position separated from the second position by a predetermined distance, and the shape of the opening 16 is a shape that prevents the display member 13 from entering.
- the shape of the opening 16 is a shape that prevents the display member 13 from entering.
- the display member 13 is a sphere, it is only necessary to provide an opening 16 having a circular cross section and a diameter of the cross section smaller than the diameter of the display member 13. Since the opening portion 16 has a shape that prevents the display member 13 from entering, only the grease flows into the second pipe 18 during lubrication.
- the position where the opening 16 is provided is determined so that the display member 13 does not prevent the grease from flowing into the second pipe 18.

- FIG. 5 is a cross-sectional view showing the movement of the display member according to the embodiment.
- FIG. 5 is a cross-sectional view taken along line BB of the greasing mechanism 1 shown in FIG.
- the display member 13 moves from the first position indicated by the dotted line in FIGS. 4 and 5 to the second position by the grease pressure during grease supply, and reaches the second position. After the greasing is completed, the display member 13 is held at the second position. For example, when the maintenance staff looks at the display window 14 and the display member 13 is in the second position as shown in FIG. 4, it can be determined that the lubrication has been performed.
- the greasing mechanism 1 is provided with a holding portion 15 that holds the moved display member 13 in the greasing pipe 10 and is provided with a display member 13 that moves according to the pressure of grease at the time of greasing. It is possible to show the implementation status.
- FIG. 6 is a diagram illustrating another configuration example of the greasing mechanism according to the embodiment.
- the greasing mechanism 1 indicates whether or not the greasing is performed, but in the example of FIG. 6, it is possible to indicate the number of times that the greasing is performed.
- the greasing pipe 10 shown in FIG. 6 includes two first pipes 17 a and 17 b and a second pipe 18. One end of the second pipe 18 is connected to the ball bearing 7 or the roller bearing 8, and the other end is connected to the respective openings 16 of the first pipes 17a and 17b.
