Godet wheel assembly and godet wheel device

Abstract

The invention discloses a godet wheel assembly and a godet wheel device. The godet wheel assembly comprises a coupler, a bearing fixed at one end of the coupler and a godet wheel provided with a mounting hole, wherein the bearing is positioned in the mounting hole of the godet wheel; a sealing element is arranged in the mounting hole outside the bearing; an outer ring of the sealing element is in close contact with the side wall of the mounting hole; an inner ring region of the sealing element is a flexible part; and the inner ring of the flexible part is in close flexible contact with the coupler so as to reduce or prevent tiny dust from entering the inside of the bearing. The godet wheel assembly has the advantages that gaps existing in the background art are eliminated, the tiny dust (short fiber wadding) can be reduced or prevented from entering the inside of the bearing, and thus the service life of the godet wheel assembly can be greatly prolonged.

Description

technical field [0001] The invention relates to a wire guide device, in particular to a passive wire guide device for ring spinning machine spinning core-spun yarn. Background technique [0002] The production of elastic textile fabrics now uses core-spun yarns, which are made of cotton yarns covered with core yarns. The core-spun yarn is generally spun by a ring spinning machine, and there is a part called a guide wire device, which plays a role in fixing the position of the core yarn. The wire guide device is fixed on the frame of the ring spinning frame. The wire guide device includes a fixed bracket and godet wheel parts arranged on both sides of the fixed bracket. The fixed bracket is composed of a long nut and a bottom bracket. The godet wheel parts include bolts The shaft, the bearing riveted on one end of the bolt shaft and the wire godet provided with a blind hole, the other end of the bolt shaft is connected to the long nut of the fixing bracket, and the bearing i...

AI Technical Summary

Problems solved by technology

[0003] The godet wheel assembly with this structure has the following problems: there is a gap between the inner ring of the ring-shaped rubber seal ring and the bolt, and it is precisely because of the gap that short fiber flocs and floating dust in the air will still enter the bearing through the gap Internally, over time, the performance of the bearings has deteriorated to such an extent that the godet wheels cannot function properly
