Horizontal balancing machine HS series

electricfor aeronautics

The high-speed balancing and over-speed testing installations are used to balance flexible rotors under operational conditions and to perform spin tests at over-speed. Hofmann HS installations cover rotor weights from just a few kilograms up to 100 tons. Special features Isotropic bearing pedestals with high stiffness to provide close to in-situ bearing conditions with high measuring sensitivity due to Hofmann force measuring principle even at low speeds designed for use with modern tilting pad journal bearings (large outer bearing diameter, higher oil flow, higher speeds) Roller bearings for low-speed balancing Flexible containment concepts Approval of containment capability by state-of-the-art computational ballistic perforation analysis applying actual fragment data Application Balancing of flexible rotors from turbo-machinery under atmospheric or vacuum conditions at low and high speeds in their own bearings Spin-testing of the rotors at over-speed Special tests with rotors from electric machines Runout measurement
