Description

Technical Field

[0001] The utility model relates to an embedded sleeve for a circular knitting machine bearing, belonging to the technical field of circular knitting machines. Background Art

[0002] Circular knitting machine generally refers to a circular weft knitting machine, a knitting machine in which the knitting needles are arranged on a circular needle cylinder and is used to produce cylindrical weft knitted fabrics. It is referred to as a circular knitting machine. The circular knitting machine is mainly composed of a yarn feeding mechanism, a weaving mechanism, a pulling-winding mechanism and a transmission mechanism. The function of the yarn feeding mechanism is to unwind the yarn from the bobbin and transport it to the weaving area. It is divided into three types: passive, active and storage types. The passive yarn feeding relies on tension to lead the yarn from the bobbin and send it into the weaving area. This yarn feeding mechanism has a simple structure, but the yarn feeding uniformity is poor. The active yarn feeding actively transports the yarn to the weaving area at a constant linear speed. The advantages are uniform yarn feeding and small tension fluctuations, which helps to improve the quality of knitted fabrics.

[0003] During the installation and use of the existing circular knitting machine bearing sleeve, when embedded installation is adopted, the bearing is embedded in the installation, and thus has no axial positioning structure during use, which can easily cause the bearing to have radial deviation, reducing the stability of the bearing during use; and when the bearing is installed in the sleeve, the bearing needs to be pressed, and it is also time-consuming and laborious to disassemble, which is not conducive to the rapid disassembly and assembly of the bearing.
