CONNECTOR MODULE BETWEEN DRIVE SHAFT OF MOTOR FAN AND ROLLING BEARING Russian patent published in 2016 - IPC F01D21/04 F01D25/16 

FIELD: electronics.

SUBSTANCE: invention relates to connection module (18) located between drive shaft (8) of aircraft engine fan and rolling bearing (12b), module includes therein inner structural element (26) attached to shaft (8) and having barrier element (32), and outer structural element (46) that is attached to bearing (12b) and supported in radial direction upon means (42) installed on inner structural element (26), and limits rolling track (48) which is complementary in relation to barrier element (32) for mutual formation of ball joint (50), held in locked state by means of locking device (34), mounted on inner structural element and extending radially outward from barrier element (32), wherein means, forming mechanical safety device (37), form connection between appliance and barrier element (32), so that ball joint is unlocked after destruction of said means. In compliance with this invention, radial support means (42) are added to device (34).

EFFECT: achieved is fact that, when ball joint is unlocked due to destruction of means forming mechanical safety device, said ball joint may operate in optimal mode without negative effect, caused by occurrence of significant resistance forces.
