Description

Technical Field

[0001] The utility model relates to a split large gear of a circular knitting machine, belonging to the technical field of large gear structures of circular knitting machines. Background Art

[0002] A knitting machine, as the name implies, is a machine for knitting fabrics. A common type is a circular knitting machine. In a circular knitting machine, a large gear is a core component. Generally speaking, the large gear is an integrally formed structure, such as an improved structure of a large gear for a knitting machine mentioned in the authorization announcement No. CN207760516U, which comprises a large gear body, an annular gear plate, a baffle cover structure, a support plate and a baffle fixing ring groove. A threaded hole is provided in the middle of the large gear body, and the threaded hole is fixedly connected to the annular gear plate through the support plate. Tooth grooves are evenly provided on the outer side of the annular gear plate, and threaded holes are evenly provided on the outer side above the baffle fixing ring groove.

[0003] In this device, the large ding gear is cast as a whole. During the actual application process, the researchers found that the large ding gear is inevitably worn during use. When replacing it, if it is replaced as a whole, it is a waste of materials. When installing the large ding gear, if it is accidentally dropped or placed, it cannot effectively reduce the buffer and protect the tooth groove, which is not conducive to its popularization and use.
