摘要： A method of forming a mold for use in the casting of a steel railway freight car truck component is provided. A cope mold is formed by providing a near net shape oversize impression of a cope pattern of a product to be cast in a flask. A cope pattern of the product to be cast is then placed on the flask forming a spacing between the cope pattern and the oversize impression. A resin coated sand is then blown to form a sand layer between the oversized impression in the flask and the cope pattern. The resin sand is set to form a mold of a thickness between the oversized impression in the flask and the cope pattern of the product to be cast. The drag mold is formed in a similar manner.

摘要： A method and apparatus for collecting ultrasonic test data from a railway wheel with an ultrasonic testing apparatus is described. The railway wheel is supported by two drive rollers, each having an indentation which engages with and rotates the wheel. An indexing transducer moves across the rotating wheel, collecting ultrasonic test data while a fixed transducer correlates a reference position on the wheel to the collected test data. To maintain the accuracy of the reference position to the collected test data, it is desirable to maintain the rotational stability of the wheel, minimizing any dynamic instability caused by dimensional tolerances in the wheel. To mitigate instabilities resulting from dimensional tolerances, the indentation of the drive rollers, which engage and drive the flange of the wheel, are variably spaced using a resilient member to maintain frictional contact between the wheel and the drive roller. This allows the indentation to accommodate the varying dimensional tolerances of the wheel flange, mitigating the possibility of dynamic instability resulting from departure of the wheel flange from the indentation.

摘要翻译： 描述了一种用超声波测试装置从铁路车轮收集超声波测试数据的方法和装置。 铁路车轮由两个驱动辊支撑，每个驱动辊具有与车轮接合并旋转的凹口。 分度传感器移动通过旋转轮，收集超声波测试数据，而固定传感器将车轮上的参考位置与收集的测试数据相关。 为了保持参考位置对所收集的测试数据的准确性，期望保持车轮的旋转稳定性，从而最小化由车轮中的尺寸公差引起的任何动态不稳定性。 为了减轻由尺寸公差引起的不稳定性，使用接合和驱动车轮的凸缘的驱动辊的凹陷使用弹性构件可变间隔，以保持车轮和驱动辊之间的摩擦接触。 这允许压痕适应车轮凸缘的变化的尺寸公差，从而减轻由轮缘从压痕偏离而引起的动态不稳定性的可能性。

摘要： A bearing assembly is provided having a roller bearing a cone forming an inner race fitted around the journal portion of an axle. A cup forms an outer raceway that combines with the inner raceway to receive roller elements. A backing ring is centered to the shaft fillet. Tapered roller elements are located between and contact the inner and outer raceways. A cage is comprised of an inner ring, and outer ring, and a plurality of pocket bars extend between the inner and outer rings. The pocket bars of the cage include a protrusion that is received in a groove in the cone.

摘要： A device for monitoring the status of a railcar handbrake having a hand operated handle, which device has a load bearing member configured to be inserted in the linkage of a railcar handbrake system so that the force applied to the brake system passes through the load bearing member. A strain gauge mounted on the load bearing member measures the strain. The information from the strain gauge is indicative of the force applied by the handbrake to the brake and is used to determine the status of the handbrake. Means for determining motion of the railcar is also provided. In one form, if it is determined that the brake is on and the railcar is in motion, information, such as an alarm, is transmitted. A system and method of monitoring a railcar handbrake are also provided.

摘要： A bearing assembly is presented having a novel lubricant sealing design that, in one embodiment, combines the sealing advantages of both a labyrinth-like seal in combination with a contact seal. The improved seal includes a non-rotating seal case working in closely spaced cooperation with a rotor to form a channel. The rotor is attached and turns with the shaft, inducing flow in the channel. Lubricant leakage is impeded by the tortuous fluid path formed by the convoluted channel of the labyrinth-like seal and the fluid shear forces developed by the turning shaft. Any lubricant leakage is further impeded by a resilient seal contacting the surface of the rotor and constricting the channel.
