Abstract

940,519. Lathes. ROLLS-ROYCE Ltd. Jan. 11, 1962, No. 1155/62. Heading B3T. [Also in Division F2] A rotatable screw 27 for indicating and/or controlling the axial movement relatively to a fixed nut 31 of a housing 51 in which the screw is mounted, is supported at its ends in ballbearings whose outer races are carried in intermediate members 43, 44 mounted in housing members 45, 46 by resilient 0-rings 47 which permit limited radial movement, the screw being axially located between a spring 60 at one end and a dumb-bell shaped thrust member 54 at the other end, the member 54 tilting to accommodate radial movements of the screw. The nut 31 has recirculating balls 33 and is coupled to a backlash-preventing nut 30 by a packing- piece 32. As shown, the screw is enclosed in a housing 51 secured to a lathe cross-slide 15 running on a guide 14 to which the nut 31 is secured, the cross-slide, Fig. 1, being moved by a separate lead-screw. The screw 27, which is reversible, is thus rotated as the slide is moved and is connected to means (not shown) indieating its position. The radially-resilient mounting of the screw 27 accommodates the small movement between the cross-slide and guide as they are clamped together and prevents the movement affecting the position-indicating means.
