摘要： PURPOSE: To obtain an oil gage capable of indicating a correct oil level independently of the time of rest or rotation by connecting the oil reservoir, which is connected to the bearing oil box and is not influenced by the dynamic pressure of oil flow of the lower part of the box, with the oil gage.
CONSTITUTION: The runner 2 is fixed to the lower end of the rotary shaft 1, the bearing shoe 3 supported by the thrust bearing 4 is in contact with the runner, and these are located in the bearing box 5 with lubricating oil 6. Also the said bearing 4 is supported by the thrust bracket with the key 9 through the frame 7, the oil reservoir 10 is provided to the inside of the bracket 8. One end of the piping 14 which communicates to the oil gage 13 is opened in the oil reservoir. By this, the oil gage 13 can indicate a correct oil level without an affection of the dynamic pressure of oil flow caused by the rotation.
