摘要： A shaft coupling includes a first shaft supported by a bearing at a first end, and a second shaft supported by a bearing at a second end. The first shaft and second shaft are coaxially arranged so that the second end of the first shaft is against the first end of the second shaft. On an end surface of the second end of the first shaft, there is a recess, and a protrusion protrudes from the end surface of the first end of the second shaft, and the recess receives the protrusion. The shaft coupling includes only one third bearing, as well as a coupler which receives the second end of the first shaft and the first end of the second shaft. With such a solution, a greater radial error may be allowed between the shafts without the structures of the coupling point being overloaded.
