Securing device for essentially cylindrical components with collars, in particular flange components

摘要

A securing device (1) for essentially cylindrical components (24) with collars (25), in particular flange components in vacuum technology, exhibits a base plate (5) and concentric securing rings (6). Each securing ring (6) is subdivided into at least two sub-rings (7), and each sub-ring (7) has an undercut in its supporting surface and a lug in its supported surface, the angle segments of which are less than 180@ or are the same. Furthermore, each sub-ring (7) exhibits a blind hole for securing the component (24) such that it is fixed in terms of rotation. <IMAGE>
