Abstract
The parts are interconnected by means of split strap arrangement engaging clamping elements which, through wedge action engage flanges of the parts and hold them together.
Claims8
Strap connection for two parts having, annular flanges or beads which, on connection, abut axially;
- overlapping endless strap means looped around said parts;
- two pins extending parallel to each other and axially to said parts the strap means looping around the two pins and being doubled back such that these pins are pulled toward each other in peripheral direction as to the parts;
- at least some part of the strap means being bi-parted;
- spread and tension means for pushing the two pins apart in the peripheral direction as far as said parts are concerned, transversally to said axes so that the strap means is tensioned;
- and
- a plurality of clamping elements arranged under bi-parted portions of the strap means and being held thereby such that axially spaced grooves in the clamping element respectively receive different single strand portions of the biparted strap means, these portions being urged radially inwardly, the clamping elements each being provided with recesses having inclined surfaces in abutment with the flanges or beads so that upon urging the clamping elements radially inwardly, the flanges or beads are engaged by the clamping elements in the respective recesses and forced axially against each other.

Strap connection for two parts having annular flanges or beads which abut in a common interface comprising:
- a pair of pins;
- a first and a second, separate strap, each strap
- (a) being endless;
- (b) looping around one of the parts;
- (c) looping around both pins of the pair, the pins extending parallel to each other, each strap doubling back at each pin;
- a plurality of clamping elements each gripping both flanges or beads to hold them together, each clamping element having two grooves, axially spaced apart for respectively engaging both straps;
- and
- tension spread means including threaded rod means at opposite pitch and being under compression, for spreading the pins away from each other to tighten the straps into engagement with the clamping elements, and urging each clamping element against both parts.
