Device for connecting a gear motor to an aircraft wheel to allow its selective drive by the gear motor.

摘要

The device has a casing (4) rotatably carrying a shaft (5) that is driven by a gear motor (2). A pinion (7) is rotatably mounted idle on the shaft by a rolling bearing. A toothed ring (3) is rotatively attached with an aircraft wheel and placed for being in permanent engagement with the idle pinion. A rotation securing unit (50) selectively constrains the idle pinion in rotation with the shaft. A smooth bearing (9) is interposed between the shaft and the rolling bearing of the pinion. A sensor senses a relative speed of rotation between inner and outer rings of the rolling bearing. An independent claim is also included for a method for detecting failure of a rolling bearing in a connection device used for connecting a gear motor to aircraft wheel.
