Abstract
A joined rotor that includes a primary join and a locking device and a method for joining thereof is disclosed. The primary join includes a threaded boss that is inserted in a tapped cavity formed in an adjacent rotor section. The primary join is locked, so as to prevent unscrewing, by at least one locking member that is located partially in both first and second rotor sections. This arrangement enables the join to be locked at a desired torque point.
