Drive system for moving staircases and pavements has a drive motor and a gearing mechanism to use a step/pallet chain/handrail drive shaft for an effective link with deflection elements/handrails.

摘要

A power divider (1) connects in series to a drive mechanism (2) with a motor and a reducing gear unit as required and has gearwheels (3-6) inside, two (4,5) of which act upon a step chain wheel shaft (7) on one side and on a handrail drive shaft (8) on the other. A pair (3,4) of gearwheels on the step chain wheel side has variable pitch circle diameters (9,10).
