1513928 Universal joints GLAENZER SPICER 9 Sept 1975 [27 Sept 1974] 37134/75 Heading F2U A universal joint comprises on a first shaft 1 three rollers 6, 7 and 8 carried by radial arms and operating in raceways of circular crosssection in a bell 9 of the second shaft, the bell having recesses 13 midway between each of two adjacent raceways to accommodate movement of the first shaft. At the maximum angle 8 it is found that the axis of the first shaft shifts between X 1 -X 1 and X 2 -X 2 which is accommodated by making the radial depth D of each recess 13 equal to E/cos #. In a second embodiment, Figs. 5 and 6 (not shown) the bell is of non-circular shape and in a third embodiment, Fig. 7 (not shown) the recesses (42) are formed by chamfers.
