The gear has a pinion (20) integrated to a shaft (201) rotary mounted in a support through a breakable element. The breakable element is arranged for disintegrating the pinion of the shaft in an event of over-torque between the pinion and the shaft. A guide module (50) is arranged with respect to the pinion for maintaining the pinion in rotation on the support during disintegration of the pinion of the shaft. The breakable element is formed of a disk (40) that is incorporated between the pinion and the shaft, where the disk comprises a breakable radial arm. |
