IPC: G11B5/52
Filed: 1987-12-25
Abstract: PURPOSE:To increase the bearing rigidity by constituting a plurality or grooves in dog-legged-form from a plurality of the first grooves which has a certain width and a depth and is formed in axis symmetry and a plurality of second grooves which has the equal depth and the larger width than those of the first groove and is formed in axis symmetry alternately with the first grooves. CONSTITUTION:The first groove 901A of a fluid bearing device 9A has a certain width and a depth, and said grooves are arranged in axis symmetry around the axis line 301 of a shaft 3. The second groove 901B has the larger width and the equal depth to those of the groove 901A, and the grooves are arranged in axis symmetry around the axis line 301 alternately with the grooves 901A. Therefore, as for the dynamic pressure distribution in the circumferential direction, a middle pressure part 122 due to the groove 901B having the larger width is generated in the intermediate part of a high pressure part 121 due to the groove 901A having the smaller width, as shown by the curve 12, and the bearing rigidity of a whole fluid bearing device 9A is increased, and the dynamic pressure distribution in the circumferential direction is made uniform in comparison with a conventional case, and the revolution vibration due to a revolution unbalanced load is reduced. Further, the bearing loss is not increased so much.
