Detailed Description
The preferred embodiments of the present invention will be further described in detail with reference to the accompanying drawings.
The conveying chain shown in fig. 1-4 comprises an inner chain plate 1, an outer chain plate 2, a pin shaft 3 and a sleeve 4, wherein the pin shaft 3 and the outer chain plate 2 are pressed to form a pin piece, the inner chain plate 1 and the sleeve 4 are pressed to form a single section, a sealing ring 5 is arranged between the single section and the pin piece, and the sealing ring 5 is an O-shaped rubber ring. The cross section of the sleeve 4 is large in the middle and small in two ends, and two ends of the sleeve 4 are connected with the inner chain plate 1. Lubricating grease is coated among the sealing ring 5, the pin shaft 3 and the sleeve 4. The chain adopts a zinc-chromium coating with the thickness of 0.05-0.08 mm, and then a sealant is added to improve the corrosion resistance of the chain.
the chain adopts a structure of a sealing ring 5, the sealing ring 5 is arranged between a single section and the pin piece, the sealing performance is better, the grease for the first lubrication in the hinge pair is ensured not to be decayed for a long time, and the maintenance-free performance is better. The inner single section and the outer single section are controlled in position in the transverse direction through the sealing ring 5, so that the chain cannot sway left and right, the stability of the chain in the conveying process is improved, and the sealing ring 5 is abutted against the sleeve 4 to generate a proper compression deformation.
The above embodiments are only used for explaining the inventive concept of the present invention, and not for limiting the protection of the claims of the present invention, and all the insubstantial modifications of the present invention made by using the above inventive concept shall fall within the protection scope of the present invention.
