Abstract

The invention discloses a method and device for balancing a journalless rotor. The method and device relate to a support structure with a support spindle (5) for supporting a journalless rotor (2) having a hole (6) in a balancing device, the support spindle (5) having Openings (10, 20) for fluid to flow through. In order to determine the imbalance with high accuracy in a rotor (2) which can be supported only over its axial extent, a first set of openings for the fluid feed (5) is provided in the support mandrel (5). 10) and a second set of openings (20) for liquid discharge.

Description

technical field

[0001] The invention relates to a method for balancing a journalless rotor and a bearing structure with a bearing mandrel for supporting a journalless, bored rotor in a balancing device. Background technique

[0002] A journaled rotor can be precisely balanced by bearing points on the journal. On the other hand, balancing rotors without their own bearing points, which are clamped on an auxiliary shaft during balancing, present great difficulties with respect to the achievable balancing accuracy.

[0003] European patent application laid-open specification EP 0 104 266 A1 discloses a method for balancing a journalless rotor without an auxiliary shaft with high balancing accuracy. For this purpose, the rotor is mounted on the bearing mandrel of the balancing machine and air is used as bearing fluid which is sent between the rotor surface and the mandrel bearing surface which lie opposite each other. Inaccuracies caused by surface accuracy no longer occur, sin...
