| 摘要 | THE PRESENT DISCLOSURE RELATES TO AN APPARATUS FOR SUPPORTING A ROTATING ELEMENT RELATIVE TO A HOUSING OF A FLUID TRANSLATING DEVICE BY PRIMARY AND SECONDARY BEARING MEANS. THE SECONDARY BEARING MEANS INCLUDES FIRST AND SECOND SLEEVES SURROUNDING THE ROTOR SUPPORTING SHAFT WITH EACH OF THE SLEEVES HAVING A PLURALITY OF OUTER RECESSES COOPERATING WITH THE HOUSING TO PRODUCE POCKETS OR CHAMBERS AND A PLURALITY OF INNER RECESSES COOPERATING WITH THE SHAFT TO PRODUCE INNER POCKETS OR CHAMBERS. EACH OUTER POCKET RECEIVES DIVERTED PRESSURED FLUID FROM THE OUTER POCKET RECEIVES DIVERTED PRESSURED FLUID FROM THE PORT WHICH IS IN OPPOSED RELATIONSHIP ON THE ROTOR OR POCKET TO DIRECT THIS FLUID INTO THE AREA BETWEEN THE SHAFT AND THE BEARING SLEEVE. THE INTERNAL SURFACE OF THE SLEEVE HAS TWO OPPOSED CIRCULAR SEGMENTS HAVING EQUAL RADII WITH THE CENTERS OF THE SEGMENTS SPACED FROM EACH OTHER WITH THE RADII BEING SUBSTANTIALLY EQUAL TO THE DIAMETER OF THE SHAFT. THE INNER POCKETS ARE DIVIDED INTO FIRST AND SECOND AXIALLY SPACED PORTIONS SO THAT ANY AXIAL MISALIGNMENT BETWEEN THE SLEEVES AND THE BEARING WILL INCREASE THE FLOW PATH BETWEEN THE BEARING AND THE SHAFT ALONG ONE EDGE OF THE SLEEVE AND DECREASE THE FLOW PATH ALONG THE OPPOSITE EDGE TO PRODUCE A PRESSURE DIFFERENTIAL THEREBY AUTOMATICALLY ALIGNING THE SLEEVE AND SHAFT. | ||||||
