False twister spindle and false twister

Abstract

A false twister spindle and a false twister, wherein the false twister spindle includes a mandrel, a bearing around the mandrel, a motor positioned at one side of the bearing to drive the mandrel to rotate in the circumferential direction; the bearing includes a radial A bearing outer ring surrounding the mandrel; the housing of the motor has a connecting ring connected with the bearing outer ring; the bearing outer ring is divided into at least a first part and a second part along the axial direction, and the second part The outer diameter is the maximum outer diameter of the outer ring of the bearing. The connecting ring is sleeved on the first part and the outer diameter of the connecting ring is not larger than the outer diameter of the second part. The connecting ring is set on the first part of the outer ring of the bearing and the outer diameter of the connecting ring is not larger than the outer diameter of the second part. The connecting ring will not prevent the spindle shaft of the false twister from being inserted into the base seat of the false twister along the axial direction of the mandrel. in the hole.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a spindle shaft of a false twister and a false twister. Background technique [0002] The spindle shaft of the false twister is a main part of the false twister. It not only plays the role of supporting the friction disc, but also drives the friction disc to rotate to achieve the purpose of friction twisting the chemical fiber. [0003] figure 1 It is a sectional view of an existing false twister spindle, which includes a mandrel 1 and a bearing 2 surrounding the mandrel 1 . At the end of the mandrel 1, there is a transmission member 3 spaced from the bearing 2. In the false twister device, the mandrel 1 drives other spindles through the transmission member 3. A motor 4 is arranged between the transmission member 3 and the bearing 2, the motor 4 and the transmission member 3 are separated from each other along the axial direction of the mandrel 1, and the motor 4 provides power...

Problems solved by technology

However, since the outer diameter of the connecting ring 8 is greater than the outer diameter of the bearing outer ring 9, that is, the connecting ring 8 protrudes from the outer circumferential surface of the bearing outer ring 9, the bearing 2 can only partially enter the seat hole of the base, and the connecting ring 8 blocks the false twister. The spindle shaft is further loaded into the base hole of the false twister device
