1526277 Universal joints CTS CORP 15 Oct 1975 [21 Oct 1974] 42215/75 Heading F2U [Also in Division H1] A device 14, e.g. of thermoplastic material, for coupling together two tongued shafts 7, 12 has two mutually perpendicular slots into which the tongues respectively project, each slot having an entrance which narrows inwardly to a region of minimum width at 22a, 23a and an internal cavity 24 of a greater width than the minimum width, the arrangement being such that at least one of the tongues does not enter its respective slot to the fullest extent. As shown, cavities 24 are cylindrical and regions 22a, 23a are hyperbolic, with the jaws of the slot being flexible. The device 14 is used to eliminate end side thrust between the rotary shaft 7 of a variable resistor and an extension shaft 12. |
