    • A winch drum (10) including a barrel portion (12) having composite flanges (16) secured on each end. The flanges (16) including two or more partially independent, segmented, modules (18, 20, 22) with each modular section placed diametrically one on the other thus forming an expanding concentric flange (16). The first modular section (18) secured to the winch drum (10), barrel portion (12) having a relatively small outside diameter with respect to the barrel (12) is treated, from a design standpoint, as the primary shear module. The second (20) and subsequent concentric sections (22) are only secured to the lower modular section (18) at their outer faces (48) and treated independently for shear and bending with each cross section being sized to accommodate the forces applicable only to that modular section thus reducing shear and bending in these modules.
    • 一种绞车鼓(10),其包括具有固定在每个端部上的复合凸缘(16)的筒部(12)。 包括两个或更多个部分独立的,分段的模块(18,20,22)的凸缘(16),每个模块部分沿径向一个放置在另一个上,从而形成扩展的同心凸缘(16)。 从设计的角度将第一模块化部分(18)固定到绞盘鼓(10),相对于筒体(12)具有相对小的外径的筒部分(12)作为主要剪切模块被处理。 第二(20)和随后的同心部分(22)仅在其外表面(48)处固定到下模块部分(18),并且独立地进行剪切和弯曲处理,每个横截面的尺寸被设计成适应仅适用于 该模块化部分因此减少了这些模块中的剪切和弯曲。
