Abstract
1,046,472. Chucks. W. NEUKOMM. May 21, 1963 [May 21, 1962], No. 20238/63. Heading B3B. [Also in Division F2] A bearing assembly of a chuck of a highprecision machine tool has at least one pair of separately-mounted elements 8, 16, 11, 17, 19 rotatable with reference to each other, the bearing surfaces of which each comprise cemented metal carbide. An outer-sleeve 3, located by a nut 4 screwed thereon, has a conical seat 5 engaged by a cone 6 of a sleeve 7 which is prevented from rotating by a rivet 27. The sleeve 7 has a bushing 8, of tungsten carbide powder sintered with powdered cobalt, brazed thereto. The sleeve 7 and the bushing 8 have a straight or helical slot 9 therein. The cone 6 may be converged inwardly by means of a nut 10. A ring 11 of cemented tungsten carbide is mounted in an annular recess of the sleeve 7. The bushing 8 and the ring 11 respectively engage a cemented tungsten carbide bushing 16, brazed on a rotatable sleeve 15, and rings 11, 19 of cemented tungsten carbide. The ring 19 is slidable on the sleeve 15 and is brazed to an annular end-face of a ring 21. The latter is positioned by means of a nut 22, screwed on to the sleeve 15 so that axial play of the sleeve 15 and the sleeve 7 can be adjusted. The sleeve 15 contains a collet 24 which can be tightened by a nut 25. The sleeve 15 is driven by a coupling-flange 29 having two pins 30 thereon for engagement with a driverplate. In a modification, a roller bearing is included in the assembly, lubricant passages and a felt-ring are provided.
