PCT No. PCT/NO93/00050 Sec. 371 Date Sep. 29, 1994 Sec. 102(e) Date Sep. 29, 1994 PCT Filed Mar. 29, 1993 PCT Pub. No. WO93/20360 PCT Pub. Date Oct. 14, 1993A swivel link, particularly for use for rotative interconnection of two relatively pivotable machine parts (1, 2) or similar mutually articulated members at their adjacent end portions. The swivel link comprises a bolt (4) and two expandable, internally conical sleeves (5', 5''). The bolt (4) is formed with two oppositely directed, conically tapering end portions (4', 4'') each intended to be positioned in an attachment hole (3) of one of the parts and to cooperate with one of said internally conical sleeves (5', 5''). A nut (6, 7) engages each of said sleeves to axially displace the respective internally conical sleeve (5', 5'') along the tapered end portions, in order to bring the latter into engagement respective attachment hole (3). The bolt (4) is formed with a through-going, central, axially directed bore (8) for rotatively accommodating a shaft (9) having threaded portions for the nuts (6, 7) carrying the conical sleeves. One of the nuts (7) and the adjacent bolt portion (4'') are provided with mutually cooperating guide/retainer elements (15, 16) preventing rotation of the nut (7) with respect to the bolt (4). This enables the conical sleeve associated with the one nut to be tightened and loosened by rotation of the shaft with respect to the bolt. |
