Abstract
1,177,830. Tensioning bolts by fluid pressure. MASCHINENFABRIK AUGSBUBG-NURN. BERG A.G. 5 June, 1967 [2 July, 1966], No. 25931/67. Heading F2H. A device for tensioning a threaded bolt 6 projecting from a support 9 for tightening a nut 5 threaded on the bolt comprises a pressure fluid-operated piston and cylinder device 2, 1 coaxially arrangeable about the projecting portion of the bolt 6 whilst being supported, e.g. by a sleeve 4, on the support .9, and an auxiliary nut 3 screwable on to the bolt 6 and having a conical surface co-operating with a conical surface on the piston, the fluid pressure acting on surfaces of the piston 2 and cylinder 1 which are parallel to said conical surfaces. Preferably, all said surfaces are inclined at 60 degrees to the axis 6a of the bolt 6. A pressure fluid is introduced through a connection 8 forcing the piston 2 outwardly and thereby effecting a desired elongation of the bolt 6. The nut 5 is then tightened by a spanner until, it abuts the support 9.
