摘要： An assembly and method for an axial compressor includes an axial shaft extending between an inlet casing and a discharge casing along the longitudinal length of a compressor housing. The axial shaft assembly includes a first stub shaft, a second stub shaft, and a hollow shaft drum having a longitudinal axis. The first stub shaft and the second stub shaft are coupled to opposing ends of the shaft drum along its longitudinal axis. A plurality of keys is disposed in a radial arrangement near the outer circumference of the first and second stub shafts and the shaft drum. A plurality of pins engage the plurality of keys, whereby the pins prevent the shaft drum from rotating axially relative to the first stub shaft and the second stub shaft and prevent the shaft drum from axially and radially separating from the stub shafts.

摘要： The impeller axial lock limits axial movement of an impeller disposed on a shaft. The impeller is spaced axially from a shaft sleeve disposed about the shaft. The impeller axial lock includes a ring member disposed about the shaft between the impeller and shaft sleeve. The ring member has a body defining a first engagement tab engaging the impeller, a second engagement tab engaging the shaft, and a third engagement tab engaging the shaft sleeve. The shaft sleeve secures the ring member to the shaft via the third engagement tab such that the ring member limits axial movement of the impeller on the shaft during rotation of the impeller. The second engagement tab engages a groove in the shaft, and the third engagement tab engages a groove in the shaft sleeve.
