A conventional example of a differential shaft generator will be explained based on FIG. 3. In this figure, shaft 2 is connected through bearing 1.
Brackets 3 and 4 that rotatably support the cylindrical frame 5 are attached to both end faces of the cylindrical frame 5, and the brackets 3 and 4 are rotatably supported by a bearing stand 6.
The bearing 1 is generally a grease-filled bearing. The shaft 2 is driven by the main engine of the ship, but since the rotational speed of the main engine fluctuates greatly, the frame 5 etc. are driven by an exhaust gas turbine etc. to equalize the fluctuations in the generator output due to this, and the rotation speed of the main engine fluctuates greatly. The output is taken out via a current collector 7 attached to the bracket 4.

Since the position is not constant, it is difficult to replenish and drain grease.

In order to achieve the above-mentioned object, the present invention supplies grease to the bearing portion from the end face of a cylindrical bearing housing through a supply path, and discharges the waste grease that has lubricated the bearing by the action of a rotating flinger or the like adjacent to the bearing. A plurality of discharge passages are provided radially in the bearing housing so as to face the flinger in the radial direction, and an annular groove communicating with the discharge passage is provided on the outer periphery of the bearing housing, and the outer surface of this groove is removably closed with an annular lid. This is how it was done.

FIG. 1 shows an embodiment of both the inventions, and the same parts as in FIG. 3 are denoted by the same reference numerals. In this figure, a bearing 11 is fitted and held from one end side into the inner peripheral part of a cylindrical bearing housing 14 in the center of a bracket 13, and the bearing housing 14
A bearing cover 15 that surrounds the end face of the bearing 11 is attached to one end face of the bearing 11 . The bearing housing 14 is provided with an axial grease supply path 16 extending from the other end surface to the inner surface of the bearing cover 15, and a nipple 17 is attached to the tip of this supply path 16. When new grease is supplied from this nipple 17 with a grease gun, the grease can be sent to the inner end surface of the bearing 11 through the supply channel 16, and this grease is pushed into the rolling parts of the bearing 11 by the pressure of the gun and lubricates them. I'm starting to do that. A disk-shaped rotating flinger 18 is disposed adjacent to the outer end surface of the bearing 11, and a discharge passage 1 for waste grease that lubricates the bearing 11 is provided in the bearing housing 14, radially facing the flinger 18.
9 are provided in a radial manner as shown in FIG. An annular groove 20 communicating with the discharge passage 19 is provided on the outer periphery of the bearing housing 14, and the outer surface of the groove 20 is closed with a removable annular lid 21. The waste grease is shaken off by the action accompanying the rotation of the flinger 18 and pushed into the discharge passage 19, and this waste grease is pushed out by the centrifugal action accompanying the rotation of the discharge passage 19 and is evenly accumulated in the groove 20. The waste grease accumulated in the groove 20 is removed from the lid 2.
1 is removed and the lubricating grease of the bearing 11 can be replaced with new one by scraping it out from the groove 20 with a scraping stick or the like.

補給および排出作業を容易に行うことができる。 According to the embodiment, the grease supply path 16 is provided from the end face of the bearing housing 14, and the waste grease that has lubricated the bearing 11 is collected in the annular groove 20 provided on the outer periphery of the bearing housing 14.
Grease replenishment and discharge operations can be easily performed regardless of the stop position of the bracket 13.

According to this invention, in a grease replenishment type bearing device for a differential shaft generator, a grease replenishment path is provided from the end face of the cylindrical bearing housing, and waste grease that has lubricated the bearing is transferred to the flinger in a radial direction by the action of a rotating flinger or the like. It is extruded from a radial discharge passage provided in the bearing housing opposite to the bearing housing, and is stored in an annular groove provided on the outer periphery of the bearing housing.
The effect is that grease can be easily replenished and discharged regardless of the stopping position of the bearing housing.
