The embodiment of the invention relates to a rope wheel, a traction wheel, an elevator driving machine and an elevator. The invention relates to the traction sheave (1, 1 ', 1' ', 1' '') for the elevator for driving a plurality of belts (2), the traction sheave comprises a central axis (x); a plurality of circular rim surfaces (3) side by side in the axial direction, the belt (2) being able to be placed against each of the rim surfaces (3) for passage; and a circular guide flange (4a-4d ''') provided at an axial side of each circular rim surface (3) for guiding the belt (2) placed against and around the rim surface (3) for passage. Each of the guide flanges (4a-4d ''') comprises a circular array of guides (5-5'''), the plurality of guides (5-5 ''') comprises guide surface portions (5a-5a''') for guiding the belt (2), and the guide surface portions (5a-5a ''') is movable towards the central axis (x). The invention also relates to the driving machine (M) and the elevator implementing the traction sheave (1, 1', 1 '', 1'' ').

    本公开的实施例涉及绳轮、曳引轮、电梯驱动机械和电梯。本发明涉及一种用于电梯的曳引轮(1、1'、1”、1”'),用于驱动多个皮带(2),曳引轮包括中心轴线(x);沿轴向方向并排的多个圆形轮缘表面(3),皮带(2)能够被放置为抵靠轮缘表面(3)中的每个轮缘表面以通过;以及设置在每个圆轮缘表面(3)的轴向侧上的圆形引导凸缘(4a‑4d”'),用于引导被放置为抵靠并且围绕轮缘表面(3)以通过的皮带(2)。引导凸缘(4a‑4d”')中的每个引导凸缘包括引导件(5‑5”')的圆形阵列,多个引导件(5‑5”')包括用于引导皮带(2)的引导表面部分(5a‑5a”'),该引导表面部分(5a‑5a”')能够朝中心轴线(x)移动。本发明还涉及一种驱动机械(M)和电梯,电梯实现曳引轮(1、1'、1”、1”')。
