Abstract
A belt drive mechanism with gear back-up comprises a driving pulley to which a driving gear is attached, a driven pulley to which a driven gear is attached, a drive belt drivingly connected between the driving and driven pulleys, and a back-up gear disposed between the driving and driven gears. When the drive belt is engaged with the driving and driven pulleys, teeth of the back-up gear are spaced apart from teeth of the driving and driven gears, and at least a portion of the teeth of the back-up gear are interposed between the teeth of the driving and driven gears. Thus, in a normal state, the drive belt is driven by the driving pulley and drives the driven pulley. However, in case of belt failure, the back-up gear is driven by the driven gear attached to the driving pulley and drives the driven gear attached to the driven pulley instead of the drive belt.
