TH118301A - A step-support structure for escalators - Google Patents

Abstract

DC60 (19/04/16) The step support structure for the escalator connects the steps to the shaft of the Steps easily And high accuracy And simply replacing the bearing without separating the step shaft, the step shaft can be rotated with the step shaft driven in the direction of Escalator movement This includes a cylindrical step sleeve arranged with a step and has Section of opening for inserting and removing the step shaft. A number of U-shaped (U) bearings, each of which includes a significantly identical outer-shaped disc, with Inside diameter of the casing of the notched steps for inserting and removing the shaft. Of steps Is set to protrude from its center In the radial direction Where a number of U-shaped (U) bearings are inserted and secured within the step sleeve in an angular position. Of the notched traces relative to the shaft of the steps are displaced apart.
