The invention discloses a low-speed heavy-load traction machine which comprises a machine base, the machine base comprises a first containing cavity and a second containing cavity, a stator and a rotor are arranged in the first containing cavity, a traction wheel is arranged in the second containing cavity, and a main shaft penetrates through the first containing cavity and the second containing cavity and is connected with the rotor and the traction wheel. The first bearing, the second bearing and the third bearing are arranged on the main shaft in a sleeving mode, the two ends of the main shaft extend out of the machine base, and the two ends of the main shaft are connected with brakes. The two brakes are adopted, so that the braking force is enhanced, and the safety performance of the elevator is improved; the machine base is designed to be of an integral structure, the traction wheel is located in the middle, the two ends of the bearing are used for supporting, stress optimization is facilitated, the traction machine is more stable and reliable when bearing large loads, the integral stability of the traction machine is improved, and the service life of the traction machine is prolonged. And by adopting an end cover mounting mode, the brake is more convenient and faster to mount and maintain.

    本发明公开了一种低速大载重曳引机,其包括一机座,所述机座包含第一收容腔和第二收容腔,所述第一收容腔内设置有定子和转子,所述第二收容腔内设置有曳引轮,主轴贯穿所述第一收容腔和第二收容腔并与转子和曳引轮连接,所述第一轴承、第二轴承和第三轴承均套设在所述主轴上,所述主轴的两端均伸出所述机座,所述主轴的两端均连接有制动器。本发明通过采用两套制动器增强了制动力,提高了电梯的安全性能;机座采用整体结构设计,曳引轮位于中间位置,并利用轴承两端支撑,便于受力的优化,使得曳引机在承受大载重时更加稳定可靠,提高了曳引机的整体稳定性和使用寿命;通过采用端盖的安装方式,使得制动器的安装和维护更加方便快捷。
