An elevator traction device with multi-motor mutual cascade belongs to the elevator technical field. The device comprises a pedestal and machine frames, a traction motor and a traction wheel which are installed at the pedestal. The present invention is characterized in that the two sides of the traction wheel are respectively provided with at least one traction motor; a traction motor shaft and a traction wheel shaft are integrated as a whole by mutual cascade. The traction wheel is installed between two machine frames as a bridge form. The present invention has reasonable and compact structure, small size and low cost; the cascade of a plurality of traction motors and the traction wheel is adopted for increasing the power, so as to meet the requirement of satisfying the elevator traction with high speed and large tonnage.
Description
technical field [0001] The invention relates to the structure of an elevator traction device, in particular to an elevator traction device in which multiple motors are cascaded with each other, and belongs to the technical field of elevators. Background technique [0002] The speed and load capacity of elevators are constantly increasing, and the existing elevator traction machine with a single traction motor and traction sheave installed on the base cannot meet the traction requirements of high-speed and large-tonnage elevators. However, the cost of the elevator traction machine capable of high-speed and ultra-high speed is very high, and the volume is huge, which is inconvenient for transportation and maintenance. Therefore, it is an urgent task for elevator research and production enterprises to research and develop a compact structure, small volume, and low cost elevator traction machine capable of high-speed and ultra-high speed.
