Abstract

In order to support a journalless rotor (2) with a hole (6) in a balancing machine using a support mandrel (5) with holes (10, 20) for the flow of fluid. , enabling the unbalance of a rotor (2) with a blind hole to be determined with high precision, the invention proposes to supply a fluid chamber (40) formed between the end of the blind hole and the end of the supporting mandrel. Fluid is introduced to form a fluid cushion that supports the rotor axially.

Description

technical field

[0001] The invention relates to a method of balancing a journalless rotor and a support device for supporting a journalless rotor with a bore in a balancing machine by means of a support mandrel. Background technique

[0002] A journaled rotor can be precisely balanced on the basis of the rotor bearing points provided on the journal. Rotors to be balanced, which do not have their own bearing points and which are clamped to the auxiliary shaft during balancing, present problems in achieving a certain balancing accuracy.

[0003] A method is known from EP 0104266 A1 with which a journalless rotor can be balanced with high balancing accuracy without an auxiliary shaft. For this purpose, the rotor is mounted on the bearing mandrel of the balancing machine and a bearing fluid is introduced between the opposing rotor and mandrel surfaces. Errors due to surface inaccuracies no longer manifest as shape deviations in the rotor bore or support mandrel are rounded or ...
