Axes of rotation intersecting zvithout viecting. In some casesof transmission between axes not parallel and not meeting it ispracticable to use an intermediate piece or link as shown in Fig. the crank pins are parallel to their respective axes and,since the angle of intersection of the axes is the same for all parts. of the revolution, the pins must make a constant angle. Theintermediate piece or block then is provided with long holesmaking this fixed angle. There is, of course, longitudinal slidingof the pieces in the holes, but this is often permissible and reallyfacilitates lubrication. This mechanism often greatly simplifiestransmission between two axes not meeting, but when an addi- tional link is employed, as sometimes must be done, it becomestoo complicated for efficient application. Here, as also in the next succeeding device—the Hooksuniversal joint—the angular velocity relations are complicated,and there are, in some instances, dead center points which mustbe overcome. Hooks universal joint is a familiar form of connectionbetween rotating axes. The coupling consists of a forked orclevis-shaped attachment on the end of each shaft. The fourbearings of these two forks fit the ends of an intermediate cross-shaped piece. Or this piece may be a di
