Abstract: A reversing gear assembly (13) for a marine angle drive comprises a horizontal input shaft (15), to be connected to a horizontally mounted engine (11) and an inclined output shaft (16) to be connected to the propeller shaft (12). Gear casing (14) includes an intermediate shaft (17) which extends parallel with the output shaft (16). The input shaft (16) fixedly mounts a cylindrical gear (22) which meshes with a forward drive conical gear (23) on the output shaft (16) and with a reverse drive cylindrical gear (25) on the intermediate shaft (17). Center of engagement between the cylindrical gears (22, 25) is located on the sole common perpendicular line of the input and intermediate shafts (15, 17). Reverse drive gear train further includes two meshing cylindrical gears (26, 24) on the intermediate and output shafts (17, 16). The gears (23, 24) on the output shaft (16) are selectively coupled to this shaft by clutch means (32).The parallel arrangement of the output and intermediate shafts (16, 17) and the use of a single conical gear (23) contributes to reducing the manufacturing cost while permitting drive of propeller shaft in either direction with equal power.

Abstract: In a traveling transmission in which an auxiliary transmission is interposed between a main clutch and a mechanical transmission, the auxiliary transmission is configured such that power transmission is cut out interlockingly with the disengagement operation of the main clutch. For example, the auxiliary transmission is configured as a high-low speed selector device including a hydraulic-operated first hydraulic clutch and a spring-operated second hydraulic clutch. Preferably, there should be provided a controller for changing the position of a direction switching valve for the first and second hydraulic clutches based on the operation of an operating member such as a pedal for disengaging the main clutch. According to the present invention, it is possible to shorten a time required for a speed change operation by the mechanical transmission and, also, to achieve a smooth operation by the mechanical transmission.

Abstract: A reversing gear assembly (13) for use in yachts having an angle drive system comprises a horizontal input shaft (15), to be connected to a horizontally mounted engine (11), and an inclined output shaft (16) to be connected to the propeller shaft (12). Gear casing (14) includes an intermediate shaft (17) which extends parallel with the output shaft (16). The forward direction drive path includes meshing cylindrical gear (18) and conical gear (20) on the input and output shafts (15, 16). The reverse direction drive path has on the input and output shafts (15, 16) two cylindrical gears (19, 21) with which a skew cylindrical gear (22) on the intermediate shaft (17) meshes at respective axial halves of the skew gear. The center of engagement between the meshing gears (19, 22) on the input and intermediate shafts (15, 17) is located on the sole, common perpendicular line of these shafts. A reversing clutch (23) is disposed on the output shaft (16).The minimum number of shafts and gears for attaining the forward and reverse direction drives and a speed reduction in a reversing gear assembly is three shafts and five gears. Using only one conical gear in such an assembly reduces the troublesome backlash-adjusting work associated with conical gears.

Abstract: A baffle plate used for a transmission that has a transmission mechanism including a rotating body operatably connected to a drive source and has a housing receiving the transmission mechanism and having a storage space where oil can be stored. The baffle plate is installed in the housing so as to separate the storage space of the housing in a liquid sealing manner into a surrounding space surrounding at least the lowermost end portion of the rotating body and into a main space other than the surrounding space. In the state installed in the housing, oil in the surrounding space is moved to the main space by pump effect induced by rotating motion of the rotating body. The baffle plate can effectively prevent, with a sufficient amount of oil stored in the housing, the lowering of transmission efficiency of the transmission mechanism caused by the stored oil.

Abstract: A reversible PTO shaft having opposite splined ends whose numbers of teeth are different from each other is inserted at one of the splined ends into an output sleeve and not-relatively rotatably connected to the output sleeve. For constituting at a position out of the PTO transmission system an actuator for changing the rotary speed of the output sleeve and holding the output sleeve changed in rotary speed simultaneously to the reversing of PTO shaft, a second collar connected to a shifter collar for changing the rotary speed of output sleeve so as to be slidable integrally with the shifter collar is disposed on an inner end of the output sleeve. When the splined end of PTO shaft having the greater number of teeth is inserted into the output sleeve, a sensor having a cam surface is moved by an end surface of the PTO shaft so as to make a pin project from the output sleeve, thereby holding the second collar at its low speed position. A power take-off assembly which sets the output sleeve into either a low speed mode or a high speed mode simultaneously to the reversing of the PTO shaft is also disclosed.

Abstract: In an inertia lock- and key-type synchronizing clutch assembly, engagement between conical clutch surfaces (29, 36) of a clutch gear (28) and synchronizer ring (35) is enhanced spontaneously under a servo action by a cam means disposed between the synchronizer ring (35) and a hub member (31). Two problems arising from the servo action are solved by additional structures provided to a key member (39) and to the synchronizer ring. That is, an unexpected spontaneous engagement of the clutch mechanism from a neutral condition thereof is prevented with certainty by a cooperation of the key member and a pair of stopper projection (48, 49) on the synchronizer ring. The key member includes at an inner surface thereof a recess (50) for permitting a rotational displacement of the sychronizer ring when a clutch-engaging operation is performed. An end face of such recess includes a ramp surface (51; 51A; 51B) which cooperates with one of the projections of the synchronizer ring so as to assure a clutch-disengaging operation even when a re-engagement of the clutch surfaces due to the servo action is caused in a clutch-disengaging process.
