Angular Coupling

The coupling mechanism illustrated in Figs. 1 and 2 is utilized for the transmission of power between two rotating shafts which are not in linear axial alignment in most cases.

Previous constant angular velocity couplings have been costly to assemble and produce. In addition, small axial movements of the driving and driven shafts have required such means as splines or a sophisticated coupling design, to eliminate vibrations induced by angular couplings which do not have a constant angular velocity characteristic.

In Fig. 1, driving shaft I is coupled to driven shaft 2 via six cylindrical projections 3. Three of these projections extend from each of shafts 1 and 2. These projections intersect an apertured disk 4 having six equally spaced apertures 5. Torque is transmitted from the cylindrical members 3 affixed to shaft 1 through the disk 4 and to the cylindrical two shafts. Small axial movements of shafts 1 and 2 are not transmitted by coupling disk 4 and impose no stress or mechanical loads on either shaft, thus allowing for end play of the shafts. Disk 4 rotates in the plane of the bisector of the angle formed between lines of intersection of the shafts 1 and 2, and is held in position by the support provided by cylindrical members 3 which intersect it. Some bearing or support for the shafts 1 and 2 would normally be included, but, for simplicity in illustration, has not been shown.
