Abstract
An escalator or moving walk has a drive arranged in a reversing area. The drive drives chain wheels that move the step band or pallet band and include a motor, an axial gear, a first hollow shaft and a second hollow shaft. The motor drives a belt to drive a gear input shaft that runs coaxial to the first hollow shaft. Arranged at one end of the gear input shaft is an operating brake; the other end of the gear input shaft is connected to the axial gear. A first flange connects a first chain wheel to a truss. A second chain wheel is arranged at one end of the second hollow shaft; the other end of the second hollow shaft is connected to the housing of the axial gear. A second flange connected to a side plate serves as a torque converter bearing for the axial gear.
