摘要:
A clamping device (10) which secures a retractor support apparatus to an operating table (12) having a side rail (14) . The clamping device (10) has a first clamping member (16) disposed between a side of the operating table (12) and the side rail (14) . The clamping device (10) also includes a second clamping member (16) disposed between the side rail (14) and the first clamping member (16) . A first securing mechanism (20) operably connects the first and second clamping member (16) s such that a force provided by the first securing mechanism (20) causes the first and second clamping member (16) s to move in opposing directions and frictionally engage the side of the operating table (12) and the side rail (14) .

Die Erfindung betrifft eine Treib- bzw. Förderkette mit jeweils durch ein Kettengelenk (11,12) miteinander verbundenen, sich in Laufrichtung (LF) erstreckenden Kettengliedern (1). Das Schwingungsverhalten einer solchen Kette soll verbessert werden. Hierzu sind zumindest einige der Kettenglieder entgegen der im Betrieb in Laufrichtung (L) wirkenden Zugkraft federelastisch gegeneinander vorgespannt.
摘要:
The invention relates to a chain link (20) of a conveying chain, containing a basic body (1) having a first end region (4) which comprises a first coupling section (7) for connecting in an articulated manner to a coupling section (8) of a first adjacent chain link, and having a second end region (5) which comprises a second coupling section (8) for connecting in an articulated manner to a coupling section (7) of a second adjacent chain link. The invention is characterized in that the basic body (1) has an intermediate region (6) which is located between the two end regions (4, 5) and comprises a body section (15) which has flexurally elastic properties and is configured such that the first end region (4) is elastically bendable out of the longitudinal direction (L) of the basic body (1) in relation to the second end region (5).

The invention relates to a conveying chain for a conveying means (1) of a conveying device, comprising a plurality of chain links (2) connected to each other, wherein the chain links (2) are connected to each other by means of articulated connections so as to each be pivotable about a first axis (A1) and about a second axis (A2) oriented perpendicular to the first axis (A1) in order to form the conveying chain. In regard to shape, the conveying chain is constructed of identical chain links (2). The chain links (2) each comprise a receptacle (5) on a first end section and a coupling body (3) on a second end section that engages in the receptacle (5) of an adjacent chain link (2), wherein the receptacle (5) and the coupling body (3) are shaped in such a way that the receptacle and the coupling body can be connected to each other by means of an insertion-rotation motion in order to form the articulated connection.

Disclosed is an improved swivel joint for use as part of a cable-guided fishing assembly. The swivel joint contains a bearing assembly comprising a series of ball bearings partially encased by an inner and outer race. During a cable-guided fishing operation, the inner and outer race exert a shearing, rather than compression, force on the ball bearing due to the unique configuration of the bearing assembly. This unique configuration increases the strength of the bearing assembly, and the corresponding strength of the swivel joint, without necessitating an increase in the outer diameter of the swivel joint.

In a transmission system, in particular a ball link transmission system, comprising driving wheel(s) and/or reversing wheel(s) (2) with a peripheral circle of concave recesses (14) which mainly have the shape of hemispheres, and cooperating therewith an endless chain (12) of hollow, spherically shaped link members (16) which are individually connected by means of linking rods (18), opposite end parts of which are pivotably embedded in the hollow link members (16), the endless chain (12) comprises hollow, spherically shaped link members (16) of plastics material and is produced by successively welding together hemispherically shaped, hollow link members (20) which prior to welding have been pivotably connected to the said linking rods (18) by means of locking means (22) cooperating with bearing means (26), at least one of the said hemispherically shaped link members (20) being formed with a side opening (40).
