TOOL FOR BALANCING A TURBINE ENGINE MODULE COMPRISING A CANTILEVERED STATOR
First Claim
1. 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:
- one stator support, intended to be 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 a front fixing support configured to extend outside of the stator,a guiding sleeve, comprising a rear end configured to confine the 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 of the stator, intended to be fixed to the support of the stator, and comprising means for immobilising the rotor with respect to the stator,a front support plate of the stator, intended to be fixed to the support of the stator, and comprising means for immobilising and centring the false bearing.

Abstract
A tool for balancing a turbine engine module in a balancer, the module including a stator, a rotor and a shaft, the balancer including at least one power drive unit and a table equipped with two support of the shaft of the module. The tool includes at least: one stator support, fixed on the table of the balancer behind the supports, a tubular false bearing, configured to support a bearing for guiding the rotor in the stator and protruding outside of the stator, a guiding sleeve of the shaft, confining a support of the false bearing, and received on the supports of the balancer, a rear support plate of the stator, fixed to the support of the stator, and immobilising the rotor with respect to the stator, a front support plate of the stator, fixed to the stator support, and immobilising and centring the false bearing.
