Abstract (en)
[origin: US4735561A] The engagement parts of the external rotor of a machine having plural fixed internal axes are reinforced by locking screws, which extend radially outwards to the side parts of the external rotor at an acute angle parallel to the longitudinal axis of said engagement parts. The thus prevented bulging of the engagement parts due to centrifugal forces permits high rotational speeds in the case of narrow sealing gaps between the external and internal rotors and with respect to the machine casing.
