Embodiment Construction

[0039] It can be seen from the background technology that the bearing raceway of the power input end of the driving spindle shaft of the existing false twister has poor load-carrying capacity.

[0040] Please refer to figure 1 , figure 1 It is a structural schematic diagram of the active spindle of a false twister.

[0041] As shown in the figure, the active spindle shaft of the false twister includes a mandrel 1, a bearing 2 surrounding the mandrel, and the bearing includes a bearing outer ring 3, a rolling body 4 at the power input end between the bearing outer ring 3 and the mandrel 1, and a working The end rolling body 5 , the power input end rolling body 4 and the working end rolling body 5 are separated from each other along the axial direction of the mandrel 1 . At the end of the mandrel 1, an axially arranged gear 6 and a pulley 7 are arranged. The pulley 7 cooperates with the driving belt and is used to receive power transmission to drive the mandrel to rotate. The ...

Abstract

The invention provides an elasticizer, a false twister unit and a false-twister driving spindle. The false-twister driving spindle includes a mandrel, bearing outer rings, work-end rolling bodies, power input end rolling bodies, wherein the mandrel includes a work end and a power input end, the bearing outer rings sleeve the mandrel, the work-end rolling bodies are arranged between the bearing outer rings and the work end of the mandrel and surround the circumference of the mandrel; each power input end rolling body is arranged between the corresponding bearing outer ring and the power input end of the mandrel and includes first rolling bodies and second rolling bodies, the first rolling bodies surround the circumference of the mandrel, are arranged at the first end in the axial directionof the bearing outer ring and can bear the radial load, and the second rolling bodies surround the circumference of the mandrel, are arranged between the work-end rolling bodies and the first rollingbodies and can bear axial and radial loads. According to the embodiment, a rollaway nest of the power input end of the provided false-twister driving spindle has longer service life.

Description

technical field [0001] The embodiment of the present invention relates to the field of textile machinery, in particular to a texturing machine, a false twister unit and a false twister driving spindle. Background technique [0002] The texturing machine is widely used in the textile industry. The false twister unit is a core component of the texturing machine. It not only supports the friction disc, but also drives the friction disc to rotate to achieve the purpose of friction twisting chemical fibers. Taking the three-axis false twister unit as an example, it includes a false twister driving spindle and two false twister driven spindles. The false twister driving spindle receives the driving force through the transmission to generate rotation, and drives the false twister The driven spindle turns. [0003] With the development of technology, more false twister units are integrated on the new texturing machine, and more false twister units lead to an increase in the input p...
