摘要： A locking ring (1) for joining a first and a second part (2, 3, respectively) of a rotor in a centrifugal separator, the first rotor part (2) having a circular cylindrical end portion (4), which has a certain inner radius and a centre line, which essentially coincides with the rotational axis, and the second part (3) has an annular flange portion (5). The locking ring (1) is arranged to be brought radially outwardly from a position radially inside the inside of the circular cylindrical end portion (4) and axially outside the annular flange portion (5) into a recess (7) and via two radially outer contact surfaces (8, 9) to abut against the end portion (4) and via inner contact surfaces (10, 11) to abut against the flange portion (5). According to the invention the locking ring (1) extends substantially a complete revolution around the rotational axis with two end surfaces turned towards one another and being so formed in one single integrated piece out of an elastically resilient material that it in unloaded condition tends to be substantially annular shaped with an outer diameter, which is at least as large as the outer radius of the recess (7), and that the contact surfaces (8, 9, 10, 11) are so located and directed that they in every axial section around the rotational axis have a middle point, in which the contact surfaces (8, 9, 10, 11) have a direction of normalcy, which is the same and coinciding for all the contact surfaces (8, 9, 10, 11), and in direction towards the separation chamber (12) in the interior of the rotor forms an acute angle with the rotational axis, the contact surfaces (8, 9, 10, 11) being substantially symmetrical with respect to this direction of normalcy.

摘要： Sealing ring (1) for a centrifugal separator with an axially open annular groove (7) for the sealing ring in a first rotor part (2) and a relative to the first rotor part (2) axially movable second rotor part (3), against which the sealing ring (1) sealingly abuts. Both the sealing ring (1) and the groove (7) has a first annular portion (8 and 9, respectively) turned towards the second rotor part (3) and a second annular portion (14 and 11, respectively) turned away from the second rotor part (3). The second portion (11) of the groove has an outer annular recess (12) and an inner annular recess (16) whereas the second annular portion (14) of the sealing ring (1) has at least one projection (15), which is arranged to at least partly fill up the outer recess of the groove (7). The sealing ring (1) and the groove (7) are so shaped and adapted to one another that the sealing ring is kept in the groove locked by its shape and the tightening force is transferred from the sealing ring (1) to the first rotor part (2) by pressing the sealing ring (1) against the bottom (13) of the groove and so that the sealing ring (1) upon elastical deformation of the same and/or the first rotor part (2) can be brought into position in and be taken out of the groove.
