The invention relates to a rotary chain for an escalator or a moving walk. The rotary chain comprises a plastic strip, a plurality of plastic shafts arranged on the plastic strip, bearing pedestals arranged at two ends of the plastic shafts, and bearings arranged on the bearing pedestals at the two ends of the plastic shafts, the plastic shafts are made of engineering plastics, and the plastic strip is made of fiber-reinforced engineering plastics. The technical problems of easy contact corrosion, large noise and bad damping effect are solved. The plastic strip is subjected to two-step moldingby each of the plastic shafts, and each plastic shaft is directly fixed on the plastic strip, so that the contact between the bearings and other metal components is avoided, thereby reducing contactcorrosion, and prolonging the service life of the rotary chain.
本发明涉及一种用于自动扶梯或自动人行道的回转链,包含一个塑料带,设置在塑料带上的多个塑料轴,设置在多个塑料轴两端的轴承座以及设置在多个塑料轴两端的轴承座上的轴承,塑料轴采用工程塑料制成,塑料带采用纤维增强工程塑料制成。解决了上述容易接触腐蚀、噪声大和阻尼效果不佳的技术问题。由于多个塑料轴中每根塑料轴对塑料带二次成型,直接将所述每根塑料轴固定在所述塑料带上,避免了轴承与另一金属部件之间的接触,从而减少了接触腐蚀,从而延长了回转链的使用寿命。
