    摘要: A bearing assembly for the rotor shaft of an open-ended spinning machine in which the bearing housing is formed with a bypass passage to allow air flow resulting from pressure differentials between the two ends of the bearing housing to bypass the bearing elements, thereby prolonging their life. In another embodiment, the bypass passage is formed in the rotor shaft.

    摘要: A rotary spindle assembly for a machine tool including a spindle supported at opposite ends by oppositely directed roller bearings. The bearing at that end of the spindle opposite to the nose end is an outer race which is axially slidable in a housing, and a plurality of compression springs are arranged between the outer race and an annular thrust block to bias the outer race away from the axial center of the spindle. Elements are provided for varying the total biasing force on the outer race and the apparatus includes a regulator for controlling the force-varying elements. The force varying elements may be apparatus for applying hydraulic pressure to supplement the biasing force or apparatus for modifying the initial compression state of the springs. The axial force on the outer race reduces or eliminates play in the bearings.

    摘要: A hydrostatic seal is provided for machine tool headstocks having rotary, or rotary and translatable, tool spindles. A pressurized air film is formed between opposite sides of a thrust ring and adjacent hydrostatic seal bearings, forming a substantially frictionless seal and preventing oil leakage from around the tool spindle.

    摘要: An improved spindle assembly for textile spinning and twisting machines is disclosed wherein a plurality of spindle blade supporting ball bearing sets and a whirl-supporting ball bearing set are aligned and supported by a single support sleeve concentric with the spindle blade which sleeve vertically terminates intermediate the whirl. One or more of said sets may have a flexible or resilient member interposed between a bearing set and the sleeve and/or the whirl and/or the spindle blade to help provide and maintain the precise alignment required of all sets from the axial centerline of the spindle blade. Also disclosed is an electromagnetically operable drive and brake clutch subassembly which is positionally adjustable on and supported by the sleeve.
