Embodiment
[0024] Embodiment: a kind of sleeve roller chain inlaid with graphite of this example, as figure 1 , figure 2 , image 3 , including an outer link plate 1 and an inner link plate 2, a pin shaft 3 is connected between the outer link plate and the inner link plate, a sleeve 4 is connected on the pin shaft, and a roller 5 is arranged outside the sleeve, as Figure 4 , Figure 5 , Image 6 , A plurality of through holes 6 are opened on the peripheral wall of the sleeve, and graphite rods 7 are embedded in the through holes. There are 16 through holes in 3 rows, which are radially distributed on the peripheral wall of the sleeve 4, and the through holes in adjacent rows are arranged at intervals, and the through holes and the pin holes of the sleeve run through. Both ends of the sleeve are provided with ring grooves 8 . A fixed plate 9 is fixed on the outer chain plate and the inner chain plate, and the fixed plate is in an “L” shape as a whole, and has a mounting hole 10 on ...

The invention relates to a manufacturing method of a chain, in particular relates to a graphite-embedded sleeve roller chain and a manufacturing method, and aims at solving the technical problems that a sleeve is quickly worn during use without lubricating oil on the chain in the prior art, finally the chain is scrapped, the device operation is influenced, oil cannot be added to a conveying transmission chain of a tobacco or food mechanism to lubricate at present. The chain comprises an outer chain plate and an inner chain plate; a hinge pin is connected between the outer chain plate and the inner chain plate; a sleeve is connected to the hinge pin; a roller is arranged at the outside of the sleeve; a plurality of through holes are formed in the circumferential wall of the sleeve; a graphite bar is embedded into each through hole. According to the chain, the wall thickness of the sleeve is slightly increased based on the self-lubricating, and a plurality of cylindrical through holes are formed in the circumferential wall of the sleeve, so that the graphite bars can be embedded into the through holes.
Description
technical field [0001] The invention relates to a chain manufacturing method, in particular to a graphite sleeve roller chain and the manufacturing method. Background technique [0002] The operation of the chain is based on the transmission principle that the sprocket rotates and advances in one direction. During the operation, the outer roller (big tube) rolls 360 degrees indefinitely, and the inner pin connects the outer chain plate and the inner section. The sleeve (small tube) is pulled forward so that the operation of the chain is achieved. There is a main part in the middle, which is the sleeve (small tube), and its outer surface is matched with the roller (big tube), and the inner hole is matched with the pin shaft, and the inner and outer sides generate friction and tension loads on each other. The Chinese patent discloses a roller chain (authorized publication number: CN 202971742 U), which includes an outer chain plate, an inner chain plate, rollers, a sleeve and...
