<p>The gear box has a shaft carrying an idle pinion (11) and a rubber spider coupling (19). The coupling has jaw clutch teeth (26a-26e) fitted in a jaw clutch side of the pinion. The side has curved U-shaped grooves (16a-16e). The groove has a base that is near the shaft carrying the pinion. The groove has branches extending radially from the shaft to receive the tooth. Each tooth is movable radially with respect to the shaft carrying the coupling for being slid along the groove when the tooth is engaged in the groove.</p> |
