An apparatus for shaping simultaneously both ends of the synthetic resin linings of a pair of metal tubes embodies a pair of carriages provided with punch means for heating and shaping the ends of the linings. A pair of carriages 5, having seated thereon a pair of hydraulically operated punches 3, are mounted for movement in opposite directions upon guide rails 4. Associated with each carriage is a clamp 6, and each clamp contains two recesses R, R1 for supporting a tube parallel to the movement of the carriages 5. A metal tube having a lining is clamped into recess R by jaws 22, 25 whence punch 3 is moved into the lining mouths at each end of the tube. Hot air is then blown through holes 3a (Fig. 2) in the punch to heat the lining, and the lining flared out. The tube is then moved into recess R ...

Universal joint for non-coaxial shafts

... 1,085,540. Universal joints; shaft couplings; telescopic shafts. VSESOJUZNY NAUCHNOISSLEDOVATELSKY 'I PROEKTNOKONSTRUCTORSKY INSTITUTE METALLURGICHESKOGO MASHINOSTROENIJA. Jan. 14, 1965, No. 1645/65. Headings F2A and F2U. In a Hooke's type universal joint, the arms 2 of two forks 1 are pivoted in a cylindrical intermediate member 4 by four bearing assemblies, each comprising, on a headed hollow pin 10 bearing in aligned radial bores in coaxial inner and outer walls 17, 16 of the member 4, an inner race 6 having end flanges a to retain rollers 5, and an outer race 7 narrower than the inner race and housed in a bore in a fork arm 2, its outer end face bearing on balls 8 running in a track 9 in the head of the pin 10. A bolt 18 screwed into a ring 19 secures the bearing assembly in position. A key 12 holds the pin 10 against rotation. For use in a rolling mill drive, two such joints are connected by a short cardan shaft. Alternatively, a longer cardan shaft 21 (Fig. 5) is used, joined at one ...
