Abstract
The present invention provides a magnetic-hydraulic double-suspension bearing experiment table. In the experiment table, four blind holes are uniformly processed on left and right side surfaces of the two radial stators for magnetic-hydraulic double-suspension bearing; four countersunk through holes are uniformly processed on left side surfaces of the left supporting part of the fixed bracket and the right supporting part of the fixed bracket, and the radial stators for magnetic-hydraulic double-suspension bearing are fixedly connected to the upper end of the left supporting part of the fixed bracket by countersunk screws. In addition, the two radial stators for magnetic-hydraulic double-suspension bearing are processed with stops to ensure that the two radial stators for magnetic-hydraulic double-suspension bearing are concentric with the left supporting part of the fixed bracket and the right supporting part of the fixed bracket.
