发明名称 Reel assembly
摘要 A capstan winch includes a reel assembly comprising a reel, which rotates, and two generally annular floating flanges which are supported so that the planes in which they rotate converge toward one another, which has the effect of creating an apparent axial movement of the flanges with respect to the reel as they rotate together. The cylindrical surface of the reel is provided with alternating lands and grooves and floating flanges have formed on them alternating inclined faces which correspond with the lands and the grooves. The inclined faces are angled so that the faces which correspond to each land on the reel are generally parallel to one another. The inclined faces which correspond to each groove converge. Consequently, substantial lateral forces are exerted on a cable being wound onto the reel only when the cable overlies the grooves and frictional forces on the cable are minimized.
