Title:
GODET ROLLER
Document Type and Number:
WIPO Patent Application WO/2016/173456
Kind Code:
A1
Abstract:
A godet roller comprises a cylindrical bushing (1) capable of rotating under the driving of an external yarn; a shaft (5), fixed relative to the rotation of the bushing (1) and a bearing (3) disposed in the bushing (1), and also comprises a connecting sleeve (2) and a connecting component. The connecting sleeve (2) can be connected to the inner surface of the bushing (1) in a manner of rotating along with the bushing (1). The connecting sleeve (2), the bearing (3) and the shaft (5) are arranged along the axial direction of the bushing (1), so that the connecting sleeve (2) and the shaft (5) are respectively located on the two opposite sides of the bearing (3) in an axial direction. The connecting component penetrates through the inner circle of the bearing (3) and can be detachably connected to the connecting sleeve (2), the outer circle of the bearing (3) is connected to the shaft (5), so that in a case in which the connecting component is not connected to the connecting sleeve (2) or the connection therebetween is canceled, at least one part of the connecting component and the bearing (3) are inserted into or moved out of the bushing (1) along the axial direction by means of the shaft (5). In the godet roller, after a bearing is damaged, the connecting component and the bearing can be pulled out together and replaced, thereby preventing the godet roller from being discarded due to inconvenience of bearing replacement, and reducing costs.
