The term “integrally geared compressor” describes equipment consisting of a large-diameter, direct-driven input gear (the “bull gear”) and one or more (to a maximum of six) driven, smaller-diameter pinions. Because each pinion end can be fitted with a bladed impeller, 12 stages of compression can be obtained. When a reader asked about the feasibility of using variable-speed drives for these integrally geared machines, we advised against it because an infinite number of resonant vibration frequencies could harm one or more of the slender, three-dimensional, contour-machined impeller blades.
