#CMT# #/CMT# The gear set has a pinion integrated with a rotating shaft mounted in an accessory gear box (100) by linking discs arranged to detach the pinion from the shaft in a case of an overcouple between the pinion and the shaft. A roller bearing (80) is mounted between the pinion and the shaft for rotatably guiding the pinion around the shaft in the case of the detaching the pinion from the shaft. The roller bearing extends circumferentially between a trunk (22) and a cylindrical ring (21). #CMT#USE : #/CMT# Gear set for use in gearing boxes for driving auxiliary machines in a turbomachine (all claimed). #CMT#ADVANTAGE : #/CMT# The roller bearing is mounted between the pinion and the shaft for rotatably guiding the pinion around the shaft in the case of the detaching the pinion from the shaft, thus maintaining the efficiency of the gear and preserving the kinematics chain despite the breakage of the shaft. The bearing is small in size and light in weight, so that the bearing can be disposed in the pinion without requiring a guiding unit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a gear set with a roller bearing. 21 : Cylindrical ring 22 : Trunk 41 : Outer ring 42 : Inner ring 80 : Roller bearing 100 : Accessory gear box. |
