    • A linear transmission assembly having a lubricant recovery module is composed of a movable member having a chamber; a first oil wick inserted into the movable member and the chamber and having a first oil-absorbable portion and a first oil-dischargeable portion; an oil tank mounted to the movable member and having an oil room for storage of lubricating oil; a second oil wick mounted to the oil tank and having a second oil-absorbable portion and a second oil-dischargeable portion, the former of which extends into the oil room for contact with the lubricating oil and the latter of which reaches the chamber; and a third oil wick having a third oil-absorbable portion and a third oil-dischargeable portion, the former of which reaches the chamber and the latter of which does not contact the lubricating oil. Thus, the lubricating can be prevented from overspill and staining the linear transmission device.

    • An improved method and apparatus for proportionately metering and selectively applying lubricant to the inner surface of a conduit as a function of the conduit curvature, to facilitate subsequent pulling of cables therethrough, is disclosed. A spreading device, when pulled through "straight" conduit sections, meters and applies lubricant in longitudinally extending spaced strips of uniform thickness around the inner circumference of the conduit. Upon approaching a curvature or bend in the conduit, pulling tension force vectors transmitted to the spreading device in the radial direction tilt the spreading device to non-concentric alignment in the conduit, causing the spreader to disproportionately apply increased quantities of lubricant to that surface of the conduit having a shorter bend radius, where such lubricant is most needed to reduce frictional sidewall forces applied to the pulled cables. When tilted, the spreader simultaneously reduces the amount of lubricant applied to the conduit wall having the longer bend radius, where such lubricant is needed least. The spreading device is of symmetrical construction, having a frusto-conical forward section, a cylindrical trailing portion and a plurality of inclined rib members that perform the lubricant metering functions. The spreader device is sized and configured to provide the desired lubricant application functions. Use of the spreading device and method of this invention enables accurate predictions to be made on the volume of lubricant that will be needed to fully complete a conduit lubrication application, even over conduits of extended length and having multiple curvatures and bends.
    • 公开了一种改进的方法和装置,用于按比例计量和选择性地将润滑剂施加到导管的内表面,作为导管曲率的函数,以便于随后拉动电缆通过其中。 当通过“直”管道部分拉伸时,扩散装置测量并且围绕导管的内周围沿纵向延伸的具有均匀厚度的间隔的条带施加润滑剂。 当接近管道中的曲率或弯曲时,沿径向方向拉动传播到扩展装置的张力矢量使扩散装置向导管中的非同心对准倾斜,导致吊具不适当地将增加量的润滑剂施加到该表面上 导管具有较短的弯曲半径,其中最需要这种润滑剂以减少施加到拉动的电缆的摩擦侧壁力。 当倾斜时,撒布机同时减少施加到具有较长弯曲半径的导管壁的润滑剂的量,其中最少需要这种润滑剂。 扩展装置具有对称结构,具有截头圆锥形前部,圆柱形后部和多个执行润滑剂计量功能的倾斜肋构件。 吊具装置的尺寸和构造适于提供所需的润滑剂应用功能。 使用本发明的铺展装置和方法能够准确地预测即使在延伸长度的管道上并且具有多个曲率和弯曲的情况下,完全完成导管润滑应用所需的润滑剂的体积。
