Problems solved by technology

[0002] With the development of society and the improvement of living standards, models with large displacement (800CC) and above have gradually developed high-end models such as off-road, straddle, street running, and all-terrain. Ordinary chains have seamed chains, which cannot meet the performance requirements of this type of locomotive.

Embodiment Construction

[0018] A lightweight X-ring oil seal chain for a large-displacement locomotive, which is composed of an outer single joint, an inner single joint and a sealing ring 6, the sealing ring 6 is located between the contact surfaces of the inner and outer single joints; the inner single joint is composed of a sleeve 4, The inner chain plate 1 and the roller 3 are assembled and matched; the outer single joint is composed of the pin shaft 5 sleeved in the sleeve 4 and the outer chain plate 2 through interference fit; the sealing ring 6 is lip-shaped: the outer chain plate 2 1. The inner chain plate 1 adopts the same sheet shape and narrow waist structure, and the inner and outer chain plates are all provided with lightening holes 7 to reduce the chain weight. After the two ends of the pin shaft 5 pass through the sleeve 4 and the outer chain plate 2, they are locked and fixed by square riveting heads. The sealing ring 6 is made of carboxylated nitrile butadiene rubber or fluorine rubb...

Abstract

The invention relates to a light-weight X-ring oil seal chain of a large-displacement locomotive. The light-weight X-ring oil seal chain comprises outer single links, inner single inks and seal ringsfor cooperation. The inner single links are formed by combining sleeves, rollers and inner chain plates. The outer single links are composed of pins arranged in the sleeves and outer chain plates in an interference fit mode. The seal rings are located between the contact surfaces of the inner and outer chain plates. The end face of each seal ring is shaped like a star. The star-shaped cross section is of a cross and circle combined structure. The star-shaped structure has the advantages of excellent wear resistance of an X-ring and excellent compression resistance of an O-ring. The four ends of each star-shaped ring are all of a circular arc structure. The diameter of the circular arc of the end, making contact with the sleeve and the corresponding outer chain plate, of each star-shaped ring is 1.4 times greater than the diameter of the circular arcs of the other three ends of the star-shaped ring. Through the technical scheme, the tensile strength and fatigue strength of the chain areimproved, the service life of the chain is prolonged, and the chain has excellent reliability.

Description

technical field [0001] The invention relates to a chain, in particular to a lightweight X-shaped ring oil seal chain for large displacement (above 800cc). Background technique [0002] With the development of society and the improvement of living standards, models with large displacement (800CC) and above have gradually developed high-end models such as off-road, straddle, street running, and all-terrain. Ordinary chains have seamed chains, which cannot meet the performance requirements of this type of locomotive. . Contents of the invention [0003] In order to break through this current situation, the object of the present invention is to provide a maintenance-free chain suitable for locomotives with a capacity above 800CC. [0004] Technical scheme of the present invention is: [0005] A lightweight X-ring oil seal chain for a large-displacement locomotive, which is composed of an outer single link, an inner single link and a sealing ring; the inner single link is com...
