Filed: 1988-12-09
Abstract: PURPOSE:To judge a time of trouble for preventing a bearing from seizing or scuffing beforehand by arranging supply passages and a return passage for pressurized hydraulic oil in an oil pressure bearing, and detecting the pressure in the return passage. CONSTITUTION:Hydraulic oil delivered from oil pump 22 gives oil pressure force to respective floating plates 12, 13 from respective supply passages 36 and returns to a tank 25 by passing through a return passage 39. Oil pressure force in a circular passage 35 is raised to an appointed value and a pressure switch 40 becomes OFF under a condition of floated and supported plates 12, 13 with hydraulic oil. When oil pressure force in the circular passage 35 is lowered below the appointed value on account of cutting off of a belt 24 or such as a trouble on the oil pump 22, the pressure switch 40 becomes ON, engine revolution speed is lowered and at the same time a warning lamp is lighted. Pressure in the circular passage 35 is small is the pressure fluctuation width influenced by delivery pressure variation of the oil pump 22, therefore judgement of a time of trouble can be precisely carried out.
