Abstract

1,274,961. Tensioning bolts. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. 22 April, 1970 [23 May, 1969], No. 19384/70. Heading F2H. [Also in Division F1] An assembly in which the bolt is pretensioned comprises, for example, a connecting rod 1 and big end 2 secured together by a bolt 3 the head 3<SP>1</SP> of which rests on a sleeve 5 made of a material having a lower thermal conductivity and a higher tensile and compressive strength than the members 1, 2 which are. secured together. A similar sleeve may be interposed between the big end 2 and a threaded member engaged by the threaded portion 3<SP>11</SP> of the bolt or the lower threaded portion 3<SP>11</SP> of the bolt may co-operate with a threaded sleeve 6 of similar material to sleeve 5 and fastened in the big end. In use, a heating rod is placed in a bore coaxial with the bolt and the bolt is tightened whilst hot, on cooling the bolt contracts and is-tensioned. In a preferred assembly the bolt shank is spaced from the members 1, 2 and the sleeves: are made. of a titanium alloy. The assembly may be used for securing cylinder heads, crank cases and cylinder blocks. Moreover, more than two members may be secured together.
