The invention discloses a motor belt pulley for an elevator door machine. The motor belt pulley comprises a belt pulley body, a first edge plate fixed to the end, close to a door machine motor, of thebelt pulley body, and a second edge plate fixed to the end, away from the door machine motor, of the belt pulley body. Internal threads are machined in the center of the belt pulley body, and wedge-shaped wheel teeth are uniformly distributed on the peripheral surface of the belt pulley. The outer diameter of the first edge plate is larger than the outer diameter of the belt pulley body, and a plurality of bolt through holes are formed in the first edge plate at intervals in the circumferential direction; and the outer diameter of the second edge plate is larger than the outer diameter of thebelt pulley body and smaller than the outer diameter of the first edge plate. The thread coordination is adopted between the motor belt pulley for the elevator door machine and the rotating shaft ofthe motor to facilitate the installation, the labor intensity of installation workers is greatly reduced, the working hours are saved, special equipment of a pressing method or a temperature differential method is not required, and the production cost is reduced.
本发明公开了电梯门机用马达皮带轮,包括一皮带轮体、固定在所述皮带轮体靠近门机马达这一端上的第一边缘板和固定在所述皮带轮体远离所述门机马达这一端上的第二边缘板,在所述皮带轮体内的中心加工有内螺纹,在所述皮带轮外周面均布加工有楔形轮齿;所述第一边缘板的外径大于所述皮带轮体的外径,在所述第一边缘板上周向间隔加工有若干螺栓通孔;所述第二边缘板的外径大于所述皮带轮体的外径而小于第一边缘板的外径。本发明的电梯门机用马达皮带轮与马达的转轴之间采用螺纹配合便于安装,大大减小安装工人劳动强度,节省工时,不需要压入法或温差法的特殊设备,降低生产成本。
