4 sealing member 16 is supported.

The device according to the invention functions as follows.

The sealing members 15 and 1 have a gap 11 (FIG. 3) between the bearing 10 and the drive member 9 facing the projection 17 of the disc 2.
6, and all the bearings 10 are in the chamber 29 (Fig. 1).
The rotor means 4 (FIG. 1) is housed within the retaining means part 5 and through the holes in the end wall 34 and flange 27 of the chamber 29 and through the holes in the disc 2 and into the blocking means, i.e. It is mounted within the disc 2.

the holding platform 36 is moved towards the drive member 9 until the annular member 42 of the movable member 39 contacts the sealing member 16;
The movable member 39 , which is then held on the base 1 by screws 37 , moves the blocking means or disk 2 until it presses against the annular shoulder 28 of the bearing flange 27 . By rotating the handle wheel 41, the handle wheel 41 can be moved in the axial direction.

It is compressed as shown in the figure. Flushing fluid is pumped from tank 33 by pump 26 to pipe 4.
4, through a non-return valve 23 and a pressure passage 20 into the gap 11, the flushing fluid enters the bearing 10 from the gap 11, passes through the bearing, escapes into the chamber 29, and then drains into the drain pipe 30 and into the pipe 31. The fluid passes through the filtration chamber (
filter-chamber) 32 and return to tank 33. The bearing 10 is flushed until it can be determined visually through the transparent side wall of the chamber 29 that the bearing 10 has been sufficiently cleaned.

After flushing, the bearing is blown with compressed air for drying, and this compressed air is passed from the conduit through the check valve 21 and the pressure passage 18 by the pump 24 to the gap 11.
and then to the bearing. The quality of this drying is likewise determined visually by the disappearance of flushing fluid droplets escaping from the bearing 10 through the gap 43 between the rotor 8 and the bearing 10.

Lubricating oil is likewise supplied through the gap 11 and the passage 22 by a pump 25. The filling of the bearing 10 with lubricating oil is visually monitored until the gap between the rotor 8 and the bearing 10 is filled with lubricating oil.

When the lubrication procedure is finished, the movable member 39 or tailstock is retracted by rotating the handle wheel 41;
The sealing members 15 and 16 are released and the disc 2 is moved towards the part 6 of the means 3 by the elastic action of the sealing members, after which the rotor means 4 is pulled out of the part.
