The invention discloses a driving main shaft assembly of an escalator. The driving main shaft assembly comprises a hollow main shaft, a bearing, an end cover, a main chain wheel hub, a step chain wheel hub and a handrail chain wheel hub, the hollow main shaft is a single main shaft; inner rings at two ends of the hollow main shaft are provided with step surfaces, and outer rings of the bearings are mounted in the step surfaces; an outer cylindrical surface is arranged in the middle of the end cover, and an inner ring of the bearing is mounted on the outer cylindrical surface; the end cover is fixed on an escalator truss; and the main chain wheel hub, the step chain wheel hub and the handrail chain wheel hub are fixed on the hollow main shaft. The escalator driving main shaft assembly is small in mass, and the shaft end structure is greatly simplified.
本发明公开了一种自动扶梯驱动主轴组件,包括空心主轴、轴承、端盖、主链轮轮毂、梯级链轮轮毂和扶手链轮轮毂;所述空心主轴为单一主轴;所述空心主轴两端的内圈具有台阶面,所述轴承的外圈安装于所述台阶面内;所述端盖中部具有外圆柱面,所述轴承的内圈安装在所述外圆柱面上;所述端盖固定在自动扶梯桁架上;所述主链轮轮毂、梯级链轮轮毂和扶手链轮轮毂固定在空心主轴上。本发明的自动扶梯驱动主轴组件质量小,轴端结构得到大幅简化。
