Abstract (en)

[origin: CN104294432A] The invention provides a false twister spindle and a false twister. The false twister spindle comprises a mandrel, a bearing surrounding the mandrel, and an electromotor located on one side of the bearing and driving the mandrel to rotate in the circumferential direction. The bearing comprises an outer bearing ring radially surrounding the mandrel. A shell of the electromotor is provided with a connecting ring connected with the outer bearing ring. The outer bearing ring is at least divided into a first part and a second part in the axial direction, the external diameter of the second part is the maximum external diameter of the outer bearing ring, the first part is sleeved with the connecting ring, and the external diameter of the connecting ring is not larger than that of the second part. The first part of the outer bearing ring is sleeved with the connecting ring, the external diameter of the connecting ring is not larger than that of the second part, and the connecting ring cannot prevent the false twister spindle from being installed in a base hole of the false twister in the axial direction of the mandrel.
