Universal spherical cardan joint for transmitting torque, has female element encircling male element and female hemisphere in continuous manner to return translation movement between male and female parts assembled by machining process

摘要

The joint has a male end comprising two semi-toric cavities with a revolution ray that is equal to difference between a ray of a loop of a male element and a ray of a junction ball (3). A ray of a section is equal to the ray of the junction ball. A female element encircles or does not encircle the male element and female hemisphere in a continuous manner so as to return translation movement between two male and female parts that are assembled by a machining process, a molding process, an extrusion process, forging mill process and heat or chemical treatment.
