In the thick plate conveying chain, the bearing top plate is fixedly connected with the chain link.

In the thick plate conveying chain, the double-sleeve structure comprises a roller wheel bushing and a pin shaft bushing.

In the thick plate conveying chain, the pin shafts are sleeved at two ends of the pin shaft in an inserting manner.

In the thick plate conveying chain, the roller is embedded and sleeved in the inner ring of the roller.

In the thick plate conveying chain, the pin shaft bushing is in interference fit with the roller bushing.

In the thick plate conveying chain, the pin shaft bushing and the roller bushing are made of GCr15 bearing steel.

In the thick plate conveying chain, the hardness value of the bushing is HRC 60.

In the thick plate conveying chain, a plastic clamp spring is arranged on the pin shaft on the outer side of the roller.

In the thick plate conveying chain, a gasket is arranged between the roller and the plastic clamp spring.

In the thick plate conveying chain, the diameter of the roller is 102mm, the length of the pin shaft is 203mm, the pitch of the chain links is 250mm, and the length of the bearing top plate is 200 mm.

Compared with the prior art, the utility model has the advantages of the durability is strong, and cost of maintenance is low.
