The invention relates to a heavy-load/high-speed elevator traction machine adopting a dual-brake-disc brake structure. The heavy-load/high-speed elevator traction machine comprises a base, a tractionwheel, a power drive part and a brake part, wherein the power drive part is fixedly connected to the base for driving the traction wheel to perform peripheral rotation motion around the center axis ofthe traction wheel; the brake part comprises a first brake sub part and a second brake sub part; the first brake sub part and the second brake sub part are fixedly connected to the base, and are arranged side by side in the horizontal direction; and the first brake sub part and the second brake sub part co-act on the traction wheel. While the traction wheel needs to brake, needed brake force is shared by the two brake parts, so that requirements, on brake ability of single brake part are reduced, and therefore, a small-sized design of the elevator traction machine is possible, and follow-up packaging, transporting and mounting are facilitated. Besides, an impact force peak value, borne at a brake moment, of a bearing which is adaptive to the traction wheel is further reduced, so that theservice life is prolonged.

    本发明涉及一种采用双制动盘制动结构的重载/高速电梯曳引机,包括底座、曳引轮、动力驱动部以及制动部。动力驱动部与底座相固定连接,以用来驱动曳引轮绕其自身中心轴线进行周向旋转运动。制动部包括有第一制动分部和第二制动分部。第一制动分部和第二制动分部均与底座相固定连接,且沿着前后方向并排而置。第一制动分部和第二制动分部共同作用于曳引轮上。当需要对曳引轮进行制动时,所需的制动力由两个制动部进行分担,从而降低了对单个制动部制动能力的要求,从而使得电梯曳引机的小型化设计成为可能,利于后续的包装、运输以及安装。另外,还有效地削减了与曳引轮相适配套使用轴承在制动瞬间所承受的冲击力峰值,进而提高了其使用寿命。
