Abstract

The invention discloses a driving device of an escalator with stable power transmission, high working efficiency, low fault rate and long service life, belonging to the technical field of the escalator. The driving device comprises a stator shaft, a rotor sleeve, a first chain wheel, a second chain wheel, a first bearing and a second bearing, wherein, the outer surface of the stator shaft is distributed with coils, and the inner surface of the rotor sleeve is distributed with permanent magnets, and the rotor sleeve is sheathed outside of the stator shaft; one end of the stator shaft is interconnected with the first chain wheel by the first bearing, and the other end thereof is interconnected with the second chain wheel by the second bearing; and one end of the rotor sleeve is fixedly connected with the first chain wheel and the other end thereof is fixedly connected with the second chain wheel.

Description

technical field [0001] The invention belongs to the technical field of escalators, in particular to a driving device for an escalator. Background technique [0002] Existing escalator driving device comprises motor, reduction box, main drive shaft, driving sprocket, first driven sprocket and second driven sprocket, driving sprocket, first driven sprocket and second driven sprocket The sprockets are all connected to the main drive shaft. The motor and gearbox transmit power to the driving sprocket through the chain, and the driving sprocket drives the main drive shaft to rotate, thereby driving the two driven sprockets to rotate, and the driven sprocket drives the steps and other components to move through the chain. In the above-mentioned escalator driving device, the power is transmitted to the driving sprocket through the motor, the reduction box and the chain, and the power transmission process is not stable, and vibration and noise are easily generated. At the same tim...
