    • A measuring apparatus for measuring forces acting upon a bearing, particularly the radial forces, effective at a roller bearing. The measuring apparatus essentially comprises two rings, typically formed of metal, which are concentrically interconnected by means of a web. The roller bearing transmits the force to be measured to one of the rings, whereas the other ring is fixed. The one ring rocks or moves in relation to the fixed ring and the deformation prevailing at the web is electrically measured and indicated in a display or indicator device. The measuring apparatus serves for measuring the tension in belts, bands, and the like.
    • 用于测量作用在轴承上的力的测量装置,特别是在滚柱轴承处有效的径向力。 测量装置基本上包括通常由金属形成的两个环,它们通过腹板同心地互连。 滚子轴承将要测量的力传递给其中一个环,而另一个环是固定的。 一个环相对于固定环摇摆或移动,并且在幅材上存在的变形被电测量并在显示器或指示器装置中指示。 测量装置用于测量带,带等中的张力。

    • A transmission for locomotives, earthmoving vehicles or analogous conveyances has two closely adjacent parallel adjustable starting torque converters, one in the forward and the other in the reverse drive train, a common first gear train which connects the primary shafts of the starting converters with each other and with the input shaft, a second gear train which connects the secondary shafts of the starting converters with each other and with the output shaft, a cruising converter which is coaxial with the starting converter of the forward drive train and has a discrete secondary shaft coaxial with the secondary shaft of the respective starting converter and connected with the output shaft by a third gear train, a hydraulic brake whose rotor is driven by the secondary shaft of the starting converter of the reverse drive train and is effective only when the output shaft rotates in the forward direction, a first control unit which engages the brake and causes evacuation of working fluid from the working circuit of the cruising converter when the RPM of the output shaft is excessive, and a second control unit which reduces the transmission of power by the starting converter of the forward gear train when the RPM of the outut shaft exceeds a rated value by 20-40 percent. The brake and the converters are mounted in the casing of the transmission at the four corners of an imaginary square. At least the starting converters have stationary housing, turbine wheels which are designed for centrifugal flow of working fluid therethrough, and annuli of adjustable guide vanes which are designed for centripetal flow of working fluid therethrough.
    • 用于机车,移土车辆或类似运输工具的变速器具有两个紧密相邻的并联可调起动变矩器,其中一个在逆向传动系中是前进的,另一个在反向传动系中,一个共同的第一齿轮系将起动转换器的主轴彼此连接 并且通过输入轴,将起动转换器的副轴彼此连接并与输出轴连接的第二齿轮系,与前进传动系的起动转换器同轴的巡航转换器,并具有离散的副轴同轴 与相应起动转换器的副轴相连,并通过第三档系与输出轴连接,液压制动器的转子由反向传动系的起动转换器的副轴驱动,仅在输出轴转动时有效 在前进方向上,接合制动器并且使工作油流排出的第一控制单元 d,当输出轴的转速过大时,巡航变换器的工作回路d;以及第二控制单元,其在远端轴的RPM超过额定值时,减速前齿轮系的起动转换器的动力传递 减少20-40%。 制动器和转换器安装在变速箱的壳体中的虚拟方形的四个角上。 至少起动转换器具有固定壳体,设计用于通过其中的工作流体的离心流动的涡轮机叶轮,以及设计用于通过其中工作流体向心流动的可调节导向叶片的环形。
