[0003] The main drive gear of the circular knitting machine is set on the base plate. The driving mechanism drives the needle cylinder seat and the needle cylinder to rotate through the main drive gear to guide the knitting needles to perform weaving operations in the needle cylinder holding mechanism. There are 6 to 8 wear-resistant blocks evenly distributed along the circumferential direction of the base plate. The wear-resistant blocks are against the inner wall of the main drive gear to keep the main drive gear stable during rotation, reduce the contact area between the main drive gear and the base plate, reduce the wear and friction when the main drive gear rotates, ensure the efficient operation of the main drive gear, and prevent the main drive gear from vibrating and making noise due to excessive friction. The wear-resistant blocks are fixed to the base plate by fastening screws, fastening nuts and locking bolts. It is necessary to regularly check and adjust their swing angle (horizontality) to keep the wear-resistant blocks in good contact with the main drive gear to reduce the vibration and noise when the driving gear rotates.
