| 摘要 | These joints are particularly useful for transmitting a flux (electrical, optical, liquid or gaseous) either entirely across the joint, or from one side of the joint to devices mounted on the joint itself that use such a flux. Such devices can, for example, be motors (240a, 240b) to drive the joint itself. The interlocking bodies (211a, 211b) are typically but not necessarily circular rings, mounted to a common internal structure that permits each body to rotate about its own axis. The resulting joints can rotate in all directions with a very high angular range -- in most cases limited only by the angle subtended by connecting stems used to mount the joint to a base or to mount objects to the joint for motion. Some of these joints have hollow central enclosures (264) for passing flexible wires or tubing (261a, 261b) to carry the flux, so that the flux can be transmitted across or into the joint with the same high degree of freedom, and yet without slip rings, brushes, or other expensive motion-accommodating components subject to wear. The common internal structure is extremely simple, inexpensive and easily made -- providing two interfitted tracks (211ab). These can take the form of four identical interfitted discs (211a, 211a', 211b, 211b'); or two identical circular- segment corner pairs, each with offset centers; or ultimately any of a great variety of arbitrary shapes that provide necessary guide surfaces for arcuate motion of the bodies. | ||||||
