Oil-film damped roller bearing |
摘要 |
An additional duct (38) led to the oil feed circuit passes through the inner ring and opens out to the outside of the inner race. The duct feeds oil through the outer ring (16) to the oil film (18) under the effect of centrifugal force generated by shaft (6) rotation. The outer ring has an annular shoulder (42) projecting radially towards the inside of the annular space. A channel (40) of the shoulder opens out in register with the additional duct and opens out into the oil film. The main duct (34) passes through the inner ring (14) and opens out into an inner race for rollers (12) to lubricate the rollers. |
