Tool for balancing a turbine engine module comprising a cantilevered stator

Tool for balancing a turbine engine module in a balancer, said module comprising at least one stator and one rotor comprising a shaft of longitudinal axis A configured to be guided by a guiding bearing inside the stator and at least one blades stage which is connected to a longitudinal end portion of said shaft and which is surrounded by said stator, and said balancer comprising at least, from the front to the rear, a power drive unit and a table provided with two front and rear supports for maintaining the shaft of the module, wherein said tool comprises at least:

• a stator support, removably fixed axially adjustably on the table of the balancer behind the supports for maintaining the shaft (18) of the module,
• a tubular false bearing, configured to support a guiding bearing of the rotor in the stator and comprising an outer front fixing support configured to extend outside of the stator,
• a guiding sleeve, comprising a rear end configured to confine the outer front fixing support of the false bearing, a front end comprising inner guiding means of the shaft of the rotor, and which is configured to be received on the rear and front supports of the table of the balancer,
• a rear support plate for supporting the stator, intended to be fixed to the stator support, and comprising means for immobilising the rotor with respect to the stator,
• a front support plate for supporting the stator, intended to be fixed to the stator support, and comprising means for immobilising and centring the false bearing.
