1532132 Reversing gearing; friction clutches HURTH VERWALTUNGS GmbH 11 Feb 1977 [6 April 1976] 05683/77 Headings F2D and F2C [Also in Division B7] A reversing gearing for a boat has an input shaft 3 which drives an output shaft 8 through bevel gears 5, 7 or 6, 7 depending on which of two multiplate friction clutches is engaged. A clutch, e.g. the left-hand clutch in Fig. 2, is engaged by moving a sleeve 16 to the left which causes an inclined surface 35 of the sleeve to engage a tooth 44 of a clutch engaging member 18 to partially engage the clutch. Full engagement is by balls 66 between wedging surfaces of the member 18 and the sleeve carrier 15. Springs 75, 76 limit the clutch engaging force so that the clutches will slip if excess torque occurs. The rotation of clutch engaging members 17 and 18 relative to the support 15 is limited by a stop co-operating with a recess (Fig. 4, not shown). |
