    • A swing reduction gear assembly for a swing device which prevents admission of grease into the same and in which the pressing force of grease squeezed out from between mutually meshing teeth of a pinion and an internal gear wheel thereof is reduced. The swing reduction gear assembly comprises a lower bearing for supporting an output shaft for rotation on a casing, a sealing collar fitted on an outer periphery of the output shaft and located above a pinion integrated with the output shaft, a retainer mounted on the casing below the lower bearing, and an oil seal fitted around the retainer and normally held in engagement with an outer periphery of the sealing collar. The oil seal has a lower face side lip portion formed thereon, and a disk-shaped plate is mounted on an outer periphery of the sealing collar such that the lower face side lip portion of the oil seal is normally held in contact with an upper face of the disk-shaped plate to prevent oil from entering the swing reduction gear drive.
    • 一种摆动装置的摆动减速齿轮(23),其防止润滑脂进入其中并且减小从小齿轮(7)的相互啮合的齿和内齿轮(11)之间挤出的油脂的挤压力。 摆动减速齿轮包括用于支撑用于在壳体上旋转的输出轴的下轴承,安装在输出轴的外周并位于与输出轴一体的小齿轮上的密封套环(15),保持器(17) 安装在下轴承(14)下方的壳体上,以及安装在保持器周围并通常与密封套环的外周接合的油封。 油封具有形成在其上的下表面侧唇部,并且盘状板安装在密封环的外周上,使得油封的下表面侧唇部通常保持与上表面 的盘形板,以防止油脂进入摆动减速齿轮。

    • A blade control device comprises a change-over switch for providing light receiving position deviation signal sent out from a light receiving device into a light receiving device control system as a command value, and a device for measuring the change in the height of the light receiving device, whereby a topographic survey is conducted based on the height change of the light receiving device.The blade control device may further be provided with a second change-over switch for providing the command value outputted from a manual command value setter during a manual operation into the light receiving device control system, whereby returning the blade to a previous position is carried out in accordance with the operation of the second change-over switch.Further, the blade position can be determined by providing an adder for adding light receiving position deviation and the operation stroke of the lift cylinder at a light receiving time and a detector for detecting the deviation between the added result by the adder and the operation stroke of the lift cylinder at the current time, and by reducing the deviation to zero.
    • 叶片控制装置包括:转换开关,用于将从光接收装置发送的光接收位置偏差信号提供到作为指令值的光接收装置控制系统;以及用于测量接收光的高度变化的装置 装置,由此基于光接收装置的高度变化进行地形测量。 叶片控制装置还可以设置有第二转换开关,用于在手动操作期间将从手动指令值设定器输出的指令值提供给光接收装置控制系统,由此将叶片返回到先前位置 根据第二转换开关的操作。 此外,刀片位置可以通过提供加法器来确定,所述加法器用于在光接收时间处增加光接收位置偏差和提升缸的操作行程,以及检测器,用于检测加法器的相加结果与操作冲程之间的偏差 在当前时间提升气缸,并将偏差减小到零。
