Drive for small boat - has belt trained over angled pulleys mounted on horizontal and inclined shafts

摘要

The drive for a small boat connects the horizontal drive shaft from the inboard engine to the angled propeller shaft which then passes through the bottom of the hull to the screw. The two shafts have cone pulleys (9, 10) on which the elastic drive belts are positioned. The angles of the pulleys are such that the drive belt can provide good torque transfer without slipping. The drive is considerably simpler and more economic than complex bevel gears.
