摘要：The shear-protected plug-in collar connection is intended for mouldings andfor socketed pipes (1) which are produced using the centrifugal casting process and inthe case of which the tip end (3) of the one pipe can be pushed into the collar end (2) ofthe other pipe with radial play. Arranged in the collar end are a sealing ring (8) and aclamping ring (14) which is constructed separately therefrom and has a large number ofclamping segments (15) which are arranged with a mutual separation in the
circumferential direction and have an outer jacket surface (17) of spherical constructionand, on their inner surface (18), in each case one tooth system (19) which, when axialforces occur as a result of the interaction of the spherical jacket surface (17) with an innersurface (18) of the pipe collar (which tapers conically to the end), press radially againstthe tip end (3). An elastomeric retaining part (20), which can be fixed on the collar end andsupports it, is integrally formed on the clamping ring (14). A design which ensures correctretention is achieved even in the case of relatively large nominal widths if the annular-disc-shaped section (23) of the retaining part, which comes to rest on the collar endsurface (22), comprises in the region of the inner edge of the collar end surface (22) atransition region (26) which is of reinforced construction and has a higher bending
strength, and from which the connecting section (24) which leads to the clamping ring(15) originates, and if the collar end surface (22) has, on the inner-edge side, a recessregion which is matched to the cross-section of the transition region (26) which is ofreinforced construction. In this case, a steel ring (28) which increases the bendingstrength and can possibly be inserted through an axial insertion gap (29) is allocated tothe transition region (26) of the retaining part, which region is of reinforced construction.……
