軸継手。 In a shaft coupling in which shafts are butt-joined, a through hole 2 with a female taper 3 or a male taper formed at the joint end of the first shaft 1 and a female thread 4 cut in the center is bored, and the second A male taper 7 or a female taper that fits with the taper is formed at the joint end of the shaft 6, and a female thread 8 is carved in the center in the same direction as the female thread of the first shaft but with a slightly different pitch. 1st and 2nd
The threaded shaft 11 that connects the shaft 6 is provided with two male threads 12 and 13 in the same direction at both ends, which engage the female thread of the first shaft and the female thread of the second shaft, respectively, and the female thread of the first shaft 1. Male screw 1 screwed into 4
An engagement recess 14 for a screwdriver member to be inserted into the through hole is formed in the end portion having the number 2 engraved therein, and the screw shaft is screwed into the respective female threads of the first shaft and the second shaft. A shaft coupling using a differential screw, characterized in that it has a structure in which the tapers of both shafts can be fitted together and separated without impact due to pitch difference only by turning.
