    • A vertical power unit includes: an engine having a vertically arranged crankshaft; a vertically arranged output shaft provided below the crankshaft; and a torque converter providing a connection between the crankshaft and the output shaft. The torque converter is arranged so as to be offset from the crankshaft toward a cylinder block of the engine. A transmission device is provided between the crankshaft and the torque converter. The output shaft is arranged coaxially with the torque converter. Thus, the center of gravity of the vertical power unit is positioned as close as possible to the central portion of the engine, thereby minimizing bias of the center of gravity due to the weight of the torque converter and the output shaft to facilitate the handling of the vertical power unit.
    • 垂直动力单元包括:具有垂直布置的曲轴的发动机; 设置在曲轴下方的垂直排列的输出轴; 以及提供曲轴和输出轴之间的连接的变矩器。 变矩器被布置成从曲轴向发动机的气缸体偏移。 在曲轴和变矩器之间设置传动装置。 输出轴与变矩器同轴设置。 因此,垂直动力单元的重心定位为尽可能靠近发动机的中心部分,由此由于液力变矩器和输出轴的重量而使重心的偏差最小化,以便于处理 垂直动力单元。

    • A vertical fluid power transmission includes: a vertical crankshaft of an engine; a vertical output shaft; and a vertical torque converter disposed between the crankshaft and the output shaft. An oil supply passage is connected to one end of the circulation circuit of the vertical torque converter, and guides a stored oil that is drawn up from an oil tank and discharged by an oil pump. An oil return passage is connected to the other one end of the circulation circuit, and leads to the oil tank. A normally-closed pressure response valve is provided in the oil return passage. The pressure response valve is opened by an upstream pressure. Thus, the oil tank for storing a working oil of the torque converter is separated from the torque converter, thereby downsizing the torque converter, and the working oil is circulated between the oil tank and the circulation circuit of the torque converter, thereby promoting cooling of the working oil.
    • 垂直流体动力传递包括:发动机的竖直曲轴; 垂直输出轴; 以及设置在曲轴和输出轴之间的垂直变矩器。 供油通道连接到垂直变矩器的循环回路的一端,并且引导从油箱抽出并被油泵排出的储油。 回油通道连接到循环回路的另一端,并通向油箱。 在回油通道中设置常闭压力响应阀。 压力响应阀由上游压力打开。 因此,用于储存变矩器的工作油的油箱与变矩器分离,从而使变矩器小型化,并且工作油在油箱与变矩器的循环回路之间循环,从而促进 工作油。

    • A gear case forming a lower part of a marine propulsion machine is provided with a gear chamber for housing a bevel gear mechanism, used for transmitting power from a drive shaft to a propeller shaft. The gear chamber is connected to the bottom of a vertical drive shaft receiving bore formed in the gear case to receive a drive shaft. The gear case is provided with a vertical shift rod receiving bore parallel to the drive shaft receiving bore and having an open upper end. A connecting hole is formed in the gear case to connect respective upper parts of the drive shaft receiving bore and the shift rod receiving bore. A covering member covers the upper open upper end of the shift rod receiving bore. A shift rod is passed through the covering member into the shift rod receiving bore. The covering member has upward bulging walls defining pressure-compensating chambers. Thus, the covering member attached to an upper part of the gear case and serving as a pressure-compensating structure reduces the number of parts and man-hours necessary for assembling the gear case assembly, and reduces the cost of the gear case assembly.
    • 形成船用推进机下部的齿轮箱设有用于容纳伞齿轮机构的齿轮室,用于将动力从驱动轴传递到传动轴。 齿轮箱连接到形成在齿轮箱中的垂直驱动轴承受孔的底部以接收驱动轴。 齿轮箱设置有与驱动轴接收孔平行的竖直移动杆接收孔,并具有敞开的上端。 在齿轮箱中形成连接孔以连接驱动轴接收孔和换档杆接收孔的相应上部。 覆盖构件覆盖换档杆接收孔的上部敞开的上端。 换挡杆穿过覆盖件进入换档杆接收孔。 覆盖构件具有限定压力补偿室的向上凸出的壁。 因此,附接到齿轮箱的上部并用作压力补偿结构的覆盖构件减少了组装齿轮箱组件所需的部件数量和工时,并且降低了齿轮箱组件的成本。
