INSTALLATION OF CALIBRATION GAUGE FOR MEASURING CONSTRAINTS

摘要

An installation for calibration of a stress gauge for an external bearing block of a turbomachine roller bearing, the bearing block including a radially internal roller bearing race. The installation includes a support table on which the bearing block is attached; an internal roller bearing ring mounted coaxial with the bearing block; a drive shaft driving the ring. The installation also includes a device for applying an axial stress to the bearing block including a support drum on which the internal ring is removably fixed and a connection with the device for applying the axial stress.

1. Installation (10) for calibration of a stress gauge for an external bearing block (12) of a turbomachine roller bearing, said bearing block (12) comprising a radially internal roller bearing race, the installation comprising:
a support table (14) on which the bearing block (12) supporting the gauge is attached; an internal roller bearing ring (18) that is mounted coaxial with the bearing block (12), that comprises a conical external face (22) that is bearing in contact with the roller bearing race of the bearing block (12) through several balls (20) or rollers; a drive shaft (36) driving the ring (18) in rotation about the principal axis (A) of the bearing block (12); means (24) of applying an axial stress to the bearing block (12); characterised in that it comprises a support drum (42) on which the internal ring (18) is removably fixed, that comprises means (38) for coupling it in rotation with the drive shaft (36) and means (32, 50) of connection with the axial stress application means (24).
