(54) BLINDED THRUST BEARING

SUPPORT SHAFT

The invention relates to marine engineering.

Known thrust bearings with a two-retentive thrust shaft, containing) a clip, a spherical liner, a balan (fats and fingers, prokod 1Shch through holes in CTeincax clips and interacting with thrust cushions. However, these puffed arms have a large envelope as well as large weight as compared with conventional resistant studs.

The purpose of the invention is to reduce the length and weight of the support.

This is accomplished by the fact that a three-bottom system of balancers that interact with the fingers and with the walls of the cage is mounted inside the cage, and the fingers rest on the seats made on the stop plates mounted on the inner surfaces of the shaft.

In order to increase the rigidity of the cage, a bed was mounted on it, a sha 11ad, made in the form of a lock, covering the wall of the cage.

FIG. 1 shows a thrust bearing with a double-comb thrust shaft, a general view; in fig. 2 - cross-section scan according to the average diameter of the thrust pads.

The thrust sub-shaft contains a two-shaft shaft 1, resting on a spherical liner 2, located in bed 3, lock-shaped and resting on the inner surface of the yoke 4. Inside the yoke, a three-row balanced balancing system 5-7.

On the inner surfaces of the shaft crests there are mounted thrust 8 and 9 with seats 10 against which fingers 11 rest,

The clip 4 lies in the recess of the housing 12 and the cover 3.

Depending on the direction of the stop, the thrust pads 8 and 9, through the fingers 11, which pass through the openings of the walls of the cage, abut against the balancers 5, which rest either on the balancers 6 or on the balancers 7.

When acting, it is time to move the crest of the shaft 1 from the stern to the nose to the thrust pads 8. From them, the thrust load is transmitted through the fingers 11 to the balancers 5, and then to the balancers 6. The balancers 5 and 6 form a circumferentially closed lever system pillows 8 persistent load. The balancers 6 abut against the nasal wall of the holder 4.

If the stop acts in the direction from nose to stern, the balancers 5 and 7 form a circumferentially closed lever system, ensuring a uniform perception of pressure load 9, and legs 8, fingers 11 and balasiers 6 do not perceive the load and remain free.
