Abstract

A false twister spindle and a false twister. The false twister spindle comprises a core shaft, a bearing surrounding the core shaft, a transmission piece located on the core shaft and separated from the bearing along an axial direction of the core shaft. The bearing comprises an outer ring of the bearing, first-group rolling elements and second-group rolling elements located between the outer ring of the bearing and the core shaft and separated from each other along the axial direction of the core shaft. The first-group rolling elements are close to the transmission piece. The second-group rolling elements are away from the transmission piece. A damping ring surrounding the core shaft is installed on an inner circumference between the outer ring of the bearing and the second-group rolling elements. The damping ring has a ring-shaped groove having an opening toward the core shaft, and the second-group rolling elements are located between the ring-shaped groove and the core shaft. The damping ring has a simple design, and can implement damping functions along an axial direction and a radical direction of the core shaft.

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 cross-sectional view of an existing false twister spindle. The false twister spindle includes a mandrel 1 and a bearing 2 surrounding the mandrel 1. The bearing 2 includes a bearing outer ring 3 located between the bearing outer ring 3 and the mandrel 1. Between the first set of rolling elements 5 and the second set of rolling elements 8 , the first set of rolling elements 5 and the second set of rolling elements 8 are spaced from each other along the axial direction of the mandrel 1 . At the end of the mandrel 1 is provided a t...
