Abstract
A coupling (14) axially and non-rotatingly connects two shafts (8, 12). Both shafts, at their ends facing one another, includes shoulders (18, 19) provided with teeth (24). A first tensioning sleeve (29) which, in its bore (28), has a set of teeth (26) matching the teeth (24), is slid onto the two sets of teeth (24) of the shoulders (18, 19), to achieve a non-rotating connection between the two shafts (8, 12). A second tensioning sleeve (30) is threaded onto the outer thread (29) of the first tensioning sleeve (25). The two tensioning sleeves (25, 30) have radially inwardly directed collars (27, 31), which axially contact a contact face (22, 23) of the two shoulders (18, 19). When threaded together, the sleeves cause the two shafts (8, 12) to be axially tensioned so that their end faces (20, 21) are axially tensioned relative to one another. In this way, it is possible to achieve a simple coupling to non-rotatingly connect two shafts, which, even under restricted space conditions, enables re-assembly to replace components.
