Problems solved by technology

Invention patent CN101451451A, the patent titled "Silent Timing Chain for Engines" includes chain pieces connected in series and pins connecting each chain piece. Each chain is composed of parallel chain pieces, and the chain pieces of adjacent chains are Interlaced and interlocking, connected by pins, the inner side of the chain piece is made with involute sprockets, the chain is embedded in the rubber belt, and made into a whole with the rubber belt, the tooth surface of the sprocket is equal to the inner tooth surface of the rubber belt , a cord is buried outside the chain in the rubber belt, and the material of the rubber belt is nitrile rubber or fluororubber. The disadvantage is that the service life is short and it needs to be replaced frequently

Embodiment Construction

[0035] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0036] Such as Figure 1-13 As shown, a kind of anti-fatigue eccentric sleeve chain includes an inner chain link 1 and an outer chain link 2 that are staggered inside and outside to form a chain. The inner chain link 1 includes a sleeve 3 and an inner chain plate 4. The sleeve 3 is interference fit with the inner chain plate 4, the outer chain link 2 includes a pin shaft 5 and an outer chain plate 6, the pin shaft 5 and the outer chain plate 6 are interference fit, and the sleeve 3 is inserted with a pin Shaft 5, the inner chain plate 4 includes an inner chain plate hole 7 and an inner chain plate outer edge arc 8, the center of the inner link plate hole 7 is offset from the inner chain plate outer edge arc 8 by 0.10 -0.40mm; the outer link plate 6 includes an outer link plate hole 9 and an outer edge arc 10 of the outer link plate, and th...

Abstract

The invention discloses an anti-fatigue eccentric sleeve chain. The anti-fatigue eccentric sleeve chain comprises an inner link and an outer link which are embedded to form a chain in an internal-and-external staggered manner, the inner link comprises a sleeve and an inner chain plate, and the sleeve is in interference fit with the inner chain plate; the outer link comprises a pin shaft and an outer chain plate, the pin shaft is in interference fit with the outer chain plate, and the pin shaft is inserted into the sleeve; the inner chain plate comprises an inner chain plate hole and an inner chain plate outer edge arc, the circle center of the inner chain plate hole and the circle center of the inner chain plate outer edge arc offset by 0.10 mm to 0.40 mm; and the outer chain plate comprises an outer chain plate hole and an outer chain plate outer edge arc, and the circle center of the outer chain plate hole and the circle center of the outer chain plate outer edge arc offset by 0.10 mm to 0.40 mm. The anti-fatigue eccentric sleeve chain is provided. By means of the chain, eccentric design is adopted, and the anti-fatigue eccentric sleeve chain has the beneficial effects of being compact in structure, high in torque, high in static strength, high in fatigue strength and long in service life.

Description

technical field [0001] The invention belongs to the technical field of chain manufacturing, and in particular relates to an anti-fatigue eccentric sleeve chain. Background technique [0002] Bushing chain refers to a chain in which there are no rollers in the component parts, and the bushing surface is in direct contact with the sprocket teeth when meshing. Invention patent CN101451451A, the patent titled "Silent Timing Chain for Engines" includes chain pieces connected in series and pins connecting each chain piece. Each chain is composed of parallel chain pieces, and the chain pieces of adjacent chains are Interlaced and interlocking, connected by pins, the inner side of the chain piece is made with involute sprockets, the chain is embedded in the rubber belt, and made into a whole with the rubber belt, the tooth surface of the sprocket is equal to the inner tooth surface of the rubber belt , the outer position of the chain in the rubber belt is buried with a cord, and th...
