    • A marine propulsion system comprising a push rod (50) for adjusting the pitch of propeller blades (34). The push rod (50) has a screw-threaded bolt (60) engaged with a nut (78). The nut (78) carries a bevel gear (84) by which the nut (78) can be rotated to cause the bolt (60) and therefore the push rod (50) to move longitudinally. The push rod (50) is connected to a claw with arms couple with pins (170). The pins (170) engage eccentric shafts (174) for unlocking a propeller base (190) so the base (190) can rotate around a transverse axis. The base (190) has an inclined surface which engages with an inclined surface defining an opening in the propeller’s hub therefore locking the propeller blade (34) in position. The inclined surfaces are disengaged by rotation of the eccentric shaft (174) thus the propeller blades (34) can be rotated to adjust the pitch and than the inclined surfaces re-engage locking the propeller blade (34) in the pitch adjusted position.
    • 一种船用推进系统,包括用于调节螺旋桨叶片(34)的桨距的推杆(50)。 推杆(50)具有与螺母(78)接合的螺纹螺栓(60)。 螺母(78)承载有锥齿轮(84),螺母(78)可以通过该锥齿轮(84)旋转,从而使螺栓(60)因此推杆(50)纵向移动。 推杆(50)连接到具有与销(170)连接的臂的爪。 销(170)接合用于解锁螺旋桨基座(190)的偏心轴(174),使得基座(190)可绕横向轴线旋转。 基部(190)具有倾斜表面,其与限定螺旋桨毂中的开口的倾斜表面接合,因此将螺旋桨叶片(34)锁定在适当位置。 倾斜表面通过偏心轴(174)的旋转而脱离,因此螺旋桨叶片34可以旋转以调节间距,而倾斜表面使螺旋桨叶片34在螺距调节位置上重新接合。

    • A control method and system for a controllable pitch marine propeller including operating modes comprised of a manoeuvering mode and a cruise mode and check modes comprised of an engine check mode and propeller check mode. The cruise mode provides for wide open throttle acceleration and power stop. Smooth transition sub-modes are provided for providing smooth transition between cruise mode and manoeuvering mode and vice versa. The system operates by a lever (28) which controls a pitch control unit (10) which in turn controls engine speed and also the pitch of propeller blades (12) of propeller (14). Thus, dependent on the position of the control lever (28) in either manoeuvering mode or cruise mode, an appropriate engine speed and propeller pitch is selected automatically for driving a watercraft.
    • 一种用于可调俯仰船用螺旋桨的控制方法和系统,包括由操纵模式和巡航模式组成的操作模式以及由发动机检查模式和螺旋桨检查模式组成的检查模式。 巡航模式提供广泛的油门加速和停电。 提供平滑过渡子模式,以提供巡航模式和操纵模式之间的平滑过渡,反之亦然。 该系统由控制变桨控制单元(10)的杠杆(28)操作,控制单元又控制发动机转速以及螺旋桨(14)的螺旋桨叶片(12)的桨距。 因此,取决于操纵杆(28)在操纵模式或巡航模式中的位置,自动选择适当的发动机速度和螺旋桨桨距来驱动船只。

    • A potentiometer is disclosed which comprises an opaque screen element (10) and light emitters and collectors (92) for transmitting light through the screen and detecting the light transmitted through the screen. The screen has three sections (A, V and B). The sections (A, V and B) have bars which are parallel to one another and extend transverse to the direction of movement of the screen (10). The section (A) has bars which are arranged in groups comprising the same number of bars, but each of a different thickness. The section (V) has two parts (35, 36), the first part has bars which are formed in the same manner as the section (A) except they are a mirror image to the bars in section (A) and each group comprises less bars than are in the groups in section (A). The second part of section (V) has individual bars which increase in thickness. Section (B) is a mirror image of section (A). This configuration allows for any drifting of voltage indicative of a change in light intensity which is detected by the emitter to be identified and compensated for because the intensity of light passing through the sections and plotted against position forms a U or V-shaped profile, with the apex identifying the maximum or minimum light intensity and therefore voltage at the collector.
    • 公开了一种电位计,其包括不透明屏元件(10)和用于透过屏幕传输光并检测透过屏幕的光的发光器和收集器(92)。 屏幕有三个部分(A,V和B)。 部分(A,V和B)具有彼此平行并且横向于屏幕(10)的移动方向延伸的条。 部分(A)具有条,它们被布置成包括相同数量的棒,但每个具有不同的厚度。 部分(V)具有两部分(35,36),第一部分具有与部分(A)相同的方式形成的条,除了它们是部分(A)中的条的镜像,并且每个组包括 少于(A)部分中的组。 部分(V)的第二部分具有增加厚度的单个条。 (B)部分是(A)部分的镜像。 这种配置允许指示由发射器检测到的光强度变化的电压的任何漂移将被识别和补偿,因为通过部分的光的强度和对位置的绘制形成U或V形轮廓,具有 顶点识别最大或最小光强度,因此识别收集器处的电压。
