CONVEYING CHAIN SPROCKET AND/OR DEFLECTION CHAIN SPROCKET HAVING AN INCREASED SERVICE LIFE.

摘要

The invention relates to an escalator (1) having a step band (7) or to a moving walkway having a pallet band, wherein the step band (7) or pallet band has at least one link chain (8) which comprises engagement points (27) which are arranged so as to follow one another at theoretically identical engagement spacings (L). The escalator (1) or the moving walkway has a first deflection region and a second deflection region with at least one conveying chain sprocket (14). The at least one link chain (8) is arranged so as to circulate between the deflection regions, and the engagement points (27) engage into tooth gaps (22) of the conveying chain sprocket (14) and optionally into tooth gaps (22) of at least one deflection chain sprocket which is arranged in the first deflection region (5). The at least one conveying chain sprocket (14) and/or the at least one deflection chain sprocket have/has a pitch circle (23) with a pitch (T) which is related to the tooth gaps (22) and corresponds to half an engagement spacing (E) of the link chain (8).
