Abstract In this escalator or in this moving walk, the drive (2) is 5 arranged in the reversing area (1). The drive (2) drives chain wheels (5, 5.1) that move the step band or pallet band (5, 5.1) and consists essentially of a motor (6), an axial gear (7), and a first hollow shaft (8) and a second hollow shaft (14). By means of a first pulley (9) the motor 10 (6) drives a belt (10) that in its turn drives a second pulley (12) that is arranged on a gear input shaft (11). Arranged at one end of the rapidly rotating gear input shaft (11) is .an operating brake 13; the other end of the gear input shaft (11) is connected to the axial gear (7). 15 The gear input shaft (11) runs coaxial to the first hollow shaft (8). A first flange (15) bears the first chain wheel (5) on the truss. Arranged at one end of the second hollow shaft (14) is the second chain wheel (5.1). The other end of the second hollow shaft (14) is connected to the housing 20 (7.1) of the axial gear (7). A second flange (16) that is connected to the side plate (4) or supporting plate (34) serves as torque converter bearing for the axial gear (7). 25 (Fig. 2) |
