    • A reverse rotation preventing device comprising: a fixed ring disposed in proximity to the external peripheral surface of a coil spring; an input coupling rotatably driven; an output coupling, to which is fixed an output shaft; and a reinforcing ring on the input side and a reinforcing ring on the output side, which cover the opposite ends of the coil spring, respectively. Engaging pawls are projected and bent in the axial direction at the both ends of the coil spring, respectively, and an engaging recession for engaging the engaging pawl is formed on each of both reinforcing rings. An engageable portion of the input coupling is engaged with an engageable pawl formed on the reinforcing ring on the input side to decrease the diameter of the coil spring, so that the output shaft is rotated. An engageable portion of the output coupling is engaged with an engageable pawl formed on the reinforcing ring on the output side to increase the diameter of the coil spring, so that the output shaft is prevented from rotating reversely.
    • 一种反向旋转防止装置,包括:设置在螺旋弹簧的外周表面附近的固定环; 输入联轴器可旋转地驱动; 输出联轴器,固定输出轴; 以及输入侧的加强环和输出侧的加强环,其分别覆盖螺旋弹簧的相对端。 啮合爪分别在螺旋弹簧的两端处沿轴向突出并弯曲,并且在两个加强环中的每一个上形成用于接合接合爪的接合凹部。 输入联轴器的可接合部分与形成在输入侧的加强环上的可接合的棘爪啮合,以减小螺旋弹簧的直径,使得输出轴旋转。 输出联轴器的可接合部分与形成在输出侧的加强环上的可接合的棘爪接合,以增加螺旋弹簧的直径,从而防止输出轴反向旋转。

    • A speed reducing device employs dampers which are provided for power transmission from a worm wheel engaged with a worm gear to an output shaft of the device so as to absorb shocks. The device does not require a metallic plate to which the dampers are adhered nor a bearing which specifically supports the output shaft. A first wheel is engaged with the worm gear and has protrusions on its plate surface facing a second wheel. The second wheel is rigidly connected to the output shaft and has protrusions on its plate surface facing the first wheel. The protrusions of the first and second wheels take complementary positions, in which each protrusion of one wheel is apart from the adjacent protrusion of the other wheel a predetermined distance with respect to the rotational direction. The dampers are provided between neighboring protrusions of the first and second wheels so that the dampers are pressed and contracted to elastically transmit power from the first wheel to the second wheel.
    • 减速装置采用阻尼器,其被设置用于从与蜗轮啮合的蜗轮到装置的输出轴的动力传递,以便吸收冲击。 该装置不需要粘附有阻尼器的金属板,也不需要专门支撑输出轴的轴承。 第一轮与蜗轮啮合并且在其板表面上具有面向第二轮的突起。 第二轮刚性地连接到输出轴上,并且在其面向第一轮的板表面上具有突起。 第一和第二轮的突出物互补位置,其中一个轮的每个突出部分相对于旋转方向与另一个轮的相邻突起分开预定距离。 阻尼器设置在第一和第二轮的相邻突起之间,使得阻尼器被按压和收缩以将动力从第一轮弹性地传递到第二轮。

    • A slip ring with which a pair of brushes make contact includes a conducting portion which extends along an outer periphery of the slip ring over an angle of preferably about 210 degrees, and a non-conducting portion which extends over an angle of about preferably 150 degrees. A conductor which forms the conducting portion has a ring-like shape and also forms the non-conducting portion. The portion of the conductor which corresponds to the non-conducting portion has a small radius such that it is buried in an insulating resin material, a window through which an insulating resin material is exposed, or a recess through which an insulating resin material is exposed. The ring-like conductor provides a balanced center of gravity to the slip ring. The conductor may also include two or more conducting portions and two or more non-conducting portions.
    • 一对刷子与之接触的滑环包括沿着滑环的外周延伸优选约210度的导电部分,以及延伸大约优选为150度的非导电部分 。 形成导电部分的导体具有环状形状并且也形成非导电部分。 对应于非导电部分的导体的部分具有小的半径,使得它被埋在绝缘树脂材料中,绝缘树脂材料暴露的窗口或绝缘树脂材料暴露的凹部 。 环形导体为滑环提供平衡的重心。 导体还可以包括两个或更多个导电部分和两个或更多个不导电部分。
