摘要： An inboard/outboard stern drive system incorporates a chain drive mechanism. A chain drive extends between the propeller shaft and an intermediate shaft mounted in the stern drive lower unit above the waterline during boat operation for driving the propeller shaft in response to rotation of the intermediate shaft. An input shaft is mounted in the upper portion of the stern drive lower unit, and is drivingly engageable with the intermediate shaft. Appropriate gears and/or sprockets are mounted to the input shaft and the intermediate shaft for transferring rotation therebetween. In a preferred embodiment, a reversing mechanism is employed for selectively imparting rotation to the intermediate shaft in either a first or second rotational direction, thereby controlling the direction of rotation of the propeller shaft. The reversing mechanism is disposed above the waterline during normal operation so as not to impinge on the submerged area of the lower unit. The location of the intermediate shaft above the waterline allows large reductions necessary to efficiently transfer power from the input shaft to the propeller shaft in high power applications, without increasing the frontal area of the submerged portion of the lower unit.

摘要： An improved hydraulic system for a twin propeller marine propulsion unit. A vertical drive shaft is operably connected to the engine of the propulsion unit and carries a pinion that drives a pair of coaxial bevel gears. An inner propeller shaft and an outer propeller shaft are mounted concentrically in the lower torpedo section of the gear case and each propeller shaft carries a propeller. To provide forward movement for the watercraft, a sliding clutch is moved in one direction to operably connect the first of the bevel gears with the inner propeller shaft to drive the rear propeller. A hydraulically operated multi-disc clutch is actuated when engine speed reaches a pre-selected elevated value to operably connect the second of the bevel gears to the outer propeller shaft, to thereby drive the second propeller in the opposite direction. The hydraulic system for actuating the multi-disc clutch includes a pump connected to the inner propeller shaft, and the pump has an inlet communicating with a fluid reservoir in the gear case and has an outlet which is connected through a hydraulic line to the multi-disc clutch. A strainer, a pressure regulator and a valve mechanism are disposed in the lower gear case and are located in series in the hydraulic line. At idle and slow operating speeds the valve is held by a solenoid in a position where the fluid is dumped to the reservoir, so that the pressure of the fluid being directed to the multi-disc clutch is insufficient to engage the clutch. At engine speeds above a preselected value, the solenoid is deenergized and the valve is then biased to a position where the fluid is delivered to the multi-disc clutch to engage the clutch and cause operation of the second propeller.

摘要： A marine propulsion device is provided wherein a flexible bellows (33) surrounding the universal joint (20) disposed between a marine engine (5) and a stern drive unit (2) is mounted to rotate with the universal joint itself. The universal joint is disposed within a chamber (61) delineated by the bellows itself and by end caps (34,43) mounted to the universal joint shafts (25,30). Supports (53,56) for the universal joint bearings (54) are constructed to permit free flow of fluid around the bearings. A quantity of lubricating oil is supplied to the chamber and at least partially fills the chamber when the latter is at rest. Upon driving rotation of the device, the bellows and universal joint and lubricating oil all rotate together. The resultant centrifugal force causes the oil to flow radially outwardly through the bearing supports to lubricate the bearings, with the oil forming a rotating mass engaging the inner bellows face. To support the bellows against the rotating mass, a helical spring (69) is mounted externally of the bellows and within the bellows convolutions, with the spring being anchored (73) adjacent both ends of the bellows. In addition, the bellows function as a finned heat radiator.

摘要： A marine drive unit (1) includes a lower propeller torpedo housing (9) of generally cylindrical configuration having a longitudinal centerline (19). A propeller shaft (17) is mounted in the housing for rotation on an axis (20) offset from the centerline. The shaft is journalled in a forward bearing assembly (18) which is held in place by a support (25) adjustably mounted to the housing and on the offset axis. A nose (30) is removably secured to the forward housing end by a mounting bolt (40) which extends into the support on the offset axis. A single multi-purpose opening or port (34) in the forward end of the nose communicates to an interior entry passage (35) in the nose. The entry passage in turn merges into a pair of passage branches (36,37). One branch (36) is disposed on the offset propeller shaft axis and receives the mounting bolt. The other branch (37) is positioned to communicate with the cooling water passages (21-23) in the lower unit, and which lead to the marine drive engine (4). A torque retention and sealing member (42) is disposed between the support and the nose. Furthermore, a torque retention and sealing member (44) is disposed between the bolt head and the inner end of its passage branch.

摘要： A marine drive for a boat (3) includes a longitudianlly extending propeller shaft (17, 37, 38) which effectively carries the propeller hub (18, 41, 42) between a pair of fore and aft conical surfaces (26-29; 44-47; 51-54) which mate with similar conical surfaces associated with the hub. These mating surfaces prevent orbiting movement of the propeller. The mating surfaces also center the hub on its axis and provide for high torque retention. The construction is such that water is kept out of the joint between the hub and propeller shaft, with pre-applied lubricant being retained therein. The inventive concepts may be utilized with a single propeller system (FIG. 2), or dual propeller installation (FIG. 4).

A dual-threaded nut (49, 37) is removably disposed within the hub recess. The outer nut threads engage the hub threads, while the inner nut threads engage the threads of the propeller shaft. A device (56, 43) is provided for securing the nut against threadable rotation in its mounting. The inventive concepts may be utilized with a single or dual propeller system or any other hub and shaft connection.
