AI Technical Summary
The existing chain structure cannot be repaired when the bearing is damaged, and the fasteners are in direct contact with the chain plates, resulting in severe wear and lack of protection.
The bearing is welded inside the sleeve and a groove is made in the inner wall of the sleeve. A retaining strip is welded to the surface of the bearing. The shaft is sleeved inside the bearing and a groove is made in the surface of the shaft. The bearing is installed by using the groove to engage the retaining strip. The surface of the shaft is threaded and fitted with rubber pads and soft pads to reduce friction. Stability is improved by using retaining rings and flat-headed pins.
This allows for the disassembly and maintenance of the bearings, reducing wear on the chain plates, improving the stability and protection of the chain, and extending the chain's service life.
