    • PROBLEM TO BE SOLVED: To provide a constant velocity universal joint which is capable of transferring constant velocity rotation even if a center shaft of an input member and a center shaft of an output member are parallel with each other and both the center shafts are separated wide.SOLUTION: An output member 3 is connected to an input member 2 via three or more sets of link mechanisms 4 in such a manner that an attitude can be changed. Each of the link mechanisms 4 includes: input side and output side arm members 5, 6, one-ends of which are connected respectively rotatably to the input member 2 and the output member 3; input side and output side link members 7, 8 which are connected respectively rotatably to another-ends of the input side and output side arm members 5, 6; a center side arm member 9, both ends of which are connected respectively individually rotatably to the input side and output side link members 7, 8; and an intermediate member 10 which is connected rotatably to a midpoint on a straight line connecting rotation pair corner parts of both ends in the center side arm member 9.

    • PURPOSE:To obtain an equal-speed movement joint which can be worked easily, by axially fitting a plurality of transmission shafts with free angular movement on the base board fixed to a basic shaft and installing with free angular movement a longitudinal movement bearing slidable onto the transmission shaft on the base board fixed to a driven shaft. CONSTITUTION:A plurality of transmission shafts 4 are axially fitted with angular movement on the concentric circles having a base shaft 1 as a center, on the base board 2 fixed to the base shaft 1, keeping a distance S1 from the intersecting point O of the base shaft and a driven shaft crossing with each other. The intermediate parts of the same number of longitudinal direction movement bearings 14 as the transmission shafts 4 are axially installed with free angular motion in the equal position to the transmission shaft 4 of the base shaft, on the base board 12 fixed to a driven shaft 11, at a distance S2 equal to the distance S1 from the intersecting point O. The transmission shaft 4 and the longitudinal direction movement bearing 14 are fitted and assembled. A ball bush is the most ideal as the longitudinal direction movement bearing 14.
    • 目的:为了获得可以容易地加工的等速运动接头,通过在固定到基本轴上的基板上轴向装配多个传动轴,并且可自由旋转地安装多个传动轴,并且可自由旋转地安装可滑动到 基板上的传动轴固定在从动轴上。 构成:将多个传动轴4轴向配合在具有基轴1的同心圆上作为中心的角运动,固定在基轴2上的基板2上,与距离轴的相交点O保持距离S1 基轴和从动轴相互交叉。 与传动轴4相同数量的纵向运动轴承14的中间部分在与基轴的传动轴4相同的位置上轴向地安装在固定到从动轴11上的基板12上 距离相交点O的距离S1相等。传动轴4和纵向运动轴承14被装配和组装。 作为纵向运动轴承14,球轴承是最理想的。
