摘要： The spring (60) includes a cylindrical body having spaced end faces (62, 63), and wall means (65) between the end faces including a plurality of tiered slots (66) and tiered lands (68) extending circumferentially, the slots (66) alternating with the lands (68). The slots (85, 88) and lands adjacent the end faces are made narrower than the remaining slots (66) to improve fatigue life. For the same purpose the lands (100) may be thickened radially adjacent their ends. The spring may be formed integrally with a nut (125) (see Fig. 8) to compose spring (17) seen in the spindle design of Fig. 1 or spring (135) see in the improved spindle design of Fig. 9 provided according to the invention.

摘要： The bearing assembly (10) is of the hydrodynamic type, for use as a spindle. It includes spaced journals mounted on a shaft (12) for rotation therewith. The housing (20) includes spaced support bearings (16, 18) cooperating with the journals to form a gas gap (16c, 18c) therebetween. The support bearings (16, 18) are resiliently mounted by flexible spring seal elements (23) in the housing for axial, radial and angular movement. The elements (23) are self-energizing and comprised of relatively low coefficient of friction materials to reduce the friction of the system thus allowing rapid adjustment of the bearing (16 or 18) in response to loads on the shaft (12). Various details are described with respect to the various structures illustrated, including the details of an air bearing spindle assembly of relatively light weight and capable of operating at speeds in excess of 100,000 RPM.
