A universal joint is two rotating joints in a single package. The two shafts are attached at a single cross-shaped spider. Two hinged ends attach to this, with each end providing one axis of rotation around the spider (Fig. 8-7). The U-joint is used for power transmission. The two ends have long shafts attached to them and these rotate. Turn one shaft and this power is transmitted through the U-joint into the other shaft. When you bend the shafts relative to each other, the U-joint transmits the power around the curve. Vehicles of all kinds, from some motorcycles to cars and tractors, use some variation of the U-joint to connect their engines to their wheels.

The standard U-joint, also called a Cardan joint after the Italian mathematician Geronimo Cardano, does have some drawbacks. At higher speeds of rotation it vibrates. If the two shafts are in a direct line, there is no problem. If there is an angle between them, and there will be because that s the whole point of this joint, the geometry of the joint describes a complex arc through space. This causes unwanted vibration at high speeds. A variation on the U-joint, called the constant velocity or CV joint, eliminates this source of vibration. CV joints are found where the rotation needs to be fast, and the simpler U-joints where rotation is slow.

Try This: The machine in Fig. 8-8 consists of two rectangular frames with three rotating joints. It s a simple machine that you can build in just a few minutes. Figure 8-9 shows the rst step. The gear inside the frame is a 24-tooth crown gear. This meshes with other gears at a right angle. This gear drives the wrist plate, which is the larger gear on the outside of the frame. In theory, more parts, perhaps making up a gripping hand, could be mounted on the wrist plate. We talk about angle-turning gears like the crown gear and bevel gears in the next chapter.

The other two gears, added in Fig. 8-10, also have 24 teeth. These mesh with the crown gear and, through the crown gear, with each other. Since they all have the same number of teeth there is no change in force or motion. What happens if you use larger or smaller gears here The last two steps, in Fig. 8-11, add small pulleys and an outer frame. The pulleys are where the power, in the form of your ngers, is applied to the machine. The axles through these pulleys and their matching gears also provide a rotating connection between the inner and outer frames. We have two sources of power that control two di erent motions. One motion is the rotation of the wrist and the other is the tilt of the inner wrist frame with the outer arm. The obvious way to manage this motion might have been to have one power source control the tilt and another to control the rotation. That s not what this machine does. You have probably noticed by now that both pulleys are involved in both motions. If you turn each pulley in opposite and equal rotations, the wrist tilts but does not turn. Note that when one pulley is moving clockwise and the other is moving counterclockwise, their top and bottom edges are moving in the same direction. Clockwise and counterclockwise is determined as you face the outside face of the pulley.

Wrist steps 3 and 4.
If you give both pulleys the same rotation, so their top edges are moving in di erent directions, the wrist turns but does not tilt. Moving one pulley and holding the other still makes the wrist both turn and tilt. Di erent rates and directions of rotation in the two pulleys change the ratio of the turning and tilting motions.
