Description

TECHNICAL FIELD

[0001] The utility model relates to chain field especially points to a chain suitable for three -dimensional path. BACKGROUND

[0002] The traditional chain is composed of inner links and outer links, including inner chain plates, outer chain plates, pin shafts, sleeves and rollers, wherein the inner chain plates are fixedly connected with the inner links by interference fit between the inner chain plates and the sleeves, the outer chain plates and the pin shafts are fixedly connected as the outer links by interference fit between the outer chain plates and the pin shafts, and the clearance fit between the rollers, the sleeves and the pin shafts realizes the rotational connection between the inner links and the outer links in the plane perpendicular to the pin shafts.

[0003] Taking the traditional chain with a section of pin shafts placed horizontally as an example, since the links are in vertical rotational connection, the chain can be bent in the vertical plane, but it is difficult to be bent in the horizontal direction. Therefore, the traditional chain is suitable for the application scenario where the chain movement path is in a plane.

[0004] However, the traditional chain is difficult to be applied to the application scenario where the chain movement path exceeds a plane.

[0005] As disclosed in the double-layer tentering setting machine with the publication number CN219908143U, the chain not only bends in the vertical plane to form a closed movement path, but also needs to be bent at an angle relative to the setting section in the horizontal plane based on the need of gradually widening the width of the cloth. In this application scenario, when the traditional chain is used, the bending of the cloth section relative to the setting section can only be realized through a long path based on the clearance fit between the sleeve and the pin shaft. This not only passively lengthens the device, but also causes serious problems of abnormal wear of the chain. SUMMARY
