Abstract
A new type of rotating shaft, is registered in succession with a stepped shaft, a bush, a bearing lock sleeve, a jacket and bearings, in which the bush is rigidly connected with a bearing lock sleeve through a dowel, the bearings are matching with the stepped shaft and bearing lock sleeves by the round keyways respectively, oil filler points are set up on the jacket, bearing lock sleeve and bush, an oil reserving space being surrounded by the stepped shaft, jacket, and the liner outside the bearing. The advantages of rotating shaft is abrasive-resistant, no need of periodic maintenance, extremely convenient in mounting and dismantling, and is dispensable in bearing tightness adjustment.
Claims7
