Preferably, the lining is a self-lubricating graphite lining.

Preferably, the height of the boss is five quarters of the thickness of the inner chain plate.

Preferably, the cotter pin is made of stainless steel.

Preferably, the bushing is the same as the sleeve in length.

Compared with the prior art, the beneficial effects are that:

1. the utility model discloses self-lubricating graphite bush can effectively reduce the wearing and tearing volume of axle sleeve and round pin axle, reduces the thickness change of axle sleeve to chain tensile length has been reduced.

2. The utility model discloses all adopt flat position cooperation between axle sleeve and the interior link joint, do not produce rotation between interior link joint and the axle sleeve to reduce the wearing and tearing volume between interior link joint and the axle sleeve, thereby reduce chain tensile length.

Detailed Description

The present invention will be further described with reference to the following specific embodiments, as shown in fig. 1 to 7: a chain structure used in severe environment comprises a plurality of chain units, each chain unit is connected in the end to form a chain,

the chain unit comprises a pin shaft 1 and a shaft sleeve 2, the shaft sleeve 2 is sleeved outside the pin shaft 1, a bushing 3 is coaxially and fixedly arranged inside the shaft sleeve 2, the bushing 3 is coaxially and rotatably connected with the pin shaft 1, the bushing 3 is a self-lubricating graphite bushing, the length of the bushing 3 is the same as that of the shaft sleeve 2, the self-lubricating graphite bushing can effectively reduce the abrasion loss between the shaft sleeve 2 and the pin shaft 1 and the thickness change of the shaft sleeve 2, so that the chain stretching length is reduced,

the two ends of the shaft sleeve 2 are respectively sleeved with an inner chain plate 4, the inner chain plates 4 are matched with the corresponding bosses at flat positions, the shaft sleeve 2 is matched with the inner chain plates 4 at the flat positions, the inner chain plates 4 and the shaft sleeve 2 do not rotate mutually, so that the abrasion loss between the inner chain plates 4 and the shaft sleeve 2 is reduced, the chain stretching length is reduced,
