Segment thrust bearing

The innovation relates to a segment thrust bearing, preferably for ship drive shafts. It can be set up separately or with others. Units, e.g. gearbox or motor, can be combined.

It is known to perform thrust bearing housings from a certain size so that they are level with the center of the shaft are divided horizontally. In the event of a malfunction or suspicion of a malfunction, it is necessary to report the entire To solve the thrust bearing housing cover and lift it off to check the condition of the thrust bearing segments. This type of construction requires a great deal of installation effort, especially since handling relatively large individual weights

in heavy seas, it is very difficult, and often even dangerous.

The task of the innovation is therefore to create a segment thrust bearing in which, without difficulty, even in tight spaces on board a ship, and without any risk of the pressure bearing segments can be checked and replaced if necessary.

The innovation is that in the thrust bearing housing a suitable for checking and replacing the segments Control opening is attached.

According to a further feature of the innovation, the inspection opening should be provided with means for securing the cover designed to be lockable segments. The lid can advantageously have a hollow Be provided with a pin extending in the radial direction and on the outer circumference of a Securing pin attached to the segment engages. The segments themselves should be displaceable in the circumferential direction and individually removable in the radial direction

be educated. When using two opposing segment rings, the inspection opening preferably be designed so that it covers both segment rings together with the cover plate. For moving the individual segments in the circumferential direction in order to remove them from the bearing for replacement it is possible to attach an angle to the thrust bearing shaft, preferably to screw it on, which reaches into the gap created by removing the fixing segment. When turning with an already existing turning machine the remaining segments are pushed one after the other in front of the opening.

In the drawing, an embodiment according to the innovation is shown and explained in more detail. Show here:

Fig. 1 shows a section through the segment thrust bearing perpendicular to the shaft axis and

Fig. 2 shows a section through the segment thrust bearing parallel to the shaft axis the control opening.

The thrust bearing essentially consists of the two segment rings 1 and 1 a of 12 segments 2 each and the thrust bearing shaft 3. It serves to absorb forces that act in the axial direction of the thrust bearing part 3. This creates pressure between the support shaft 3 ^and the segments 2 nd relative movement. In the upper housing part 10 of the thrust bearing, the inspection opening 7 is attached with a cover 5 which engages with a hollow pin 11 over a locking pin 12 of the fixing segment 6. This prevents the individual segments 2 from being displaced in the circumferential direction. The Abschlussdedcel 5 is secured by screws 4. To facilitate the removal of the individual segments 2, the angle 8, which is fastened by means of screw 9 on the thrust bearing shaft 3 is used.

As a preventive maintenance measure, it is advisable to clean the running surfaces of the thrust bearing shaft at certain time intervals and to subject the segments to a close inspection. This can be done after removing the screws 4 and the cover 5 through the fixing segment 6

the opening 7 can be removed and checked. If the control of this segment 6 and the part of the running surface on the thrust bearing shaft 3 that has now become free should make it appear advisable to check all segments 2 of the segment ring 1, after fastening the angle 8 with the screw 9, all
Segments of the segment ring 1 are rotated individually in front of the opening 7 and removed with the help of an already existing turning machine. After the check, the same segments 2 or corresponding replacement segments can be installed again through the opening 7 after removing the angle δ.

With the newly designed thrust bearing, it is possible without difficulty, even in tight spaces
Examine ship engine rooms and, in heavy seas, a thrust bearing and, if necessary, the segments
au s to alternate.
