Abstract

823,643. Eccentrics. BRINEY MANUFACTURING CO. Sept. 6, 1957 [Oct. 22, 1956], No. 28198/57. Class 122 (1). [Also in Groups XXII and XXIV] An eccentric mechanism for laterally adjusting a driven element relatively to a driving element, e.g. the boring bar 14 relatively to its holder 10, Fig. 3, comprises a cylindrical post 32 on the boring-bar received in a cylindrical aperture 30 in the holder, an angularly adjustable eccentric bush 22 between the facing cylindrical faces of the elements, and antifriction means 34, 36 between the bush and the cylindrical surfaces of the elements. The post 32 on the boring-bar 14 is mounted in a prestressed ball-bearing 36 in the eccentric bush, which bears in a pre-stressed ball-bearing 34 in the holder 10. A frusto-conical shoulder 66 on the bar 14 is pressed against a seating in the bush and the bush against a similar seating in the holder by springs 58 in pockets 56 in a nut 52 on the end of the post 32. The holder drives the boring-bar by a key 62 engaging slots 60, 64 in the nut 52 and holder respectively. Graduations 44 on the periphery of the bush 22 and a mark 46 on the holder facilitate adjustments of the bar which are effected by turning the bush with a wrench engaging pockets 70 in the bush. A turning or facing tool 20, Fig. 2, is mounted on a flange 11 of the holder 10 by an annular ring 18 pressed by springs 116 against the flange. One end of each spring 116 engages the head of a bolt 110 carried by the flange and passing through a clearance hole 120 in the ring 18. The clearance hole 120 in the ring 18. The clearance holes 120 permit adjustment of the ring 18 by means of an eccentric bush 75 rotated between the holder or a sleeve thereon and the bore of the ring or a bush therein. Pre-stressed ballbearings 86, 88 are positioned between the bush and the holder respectively. The bush 75 is retained in adjusted position by a spring- pressed pin 92. The ring 18 is driven by a pin 123.
