The invention relates to an elevator traction machine. The elevator traction machine comprises a machine case, a rotary shaft, a traction wheel, a rotor, a stator, a rear end cover, a front bearing, arear bearing and cooling plates. The rear end cover and the machine case are buckled to form an assembly chamber. The front bearing and the rear bearing are mounted on the machine case and the rear end cover correspondingly. The rotary shaft penetrates through the front bearing, the assembly chamber and the rear bearing in sequence. The traction wheel is sleeved on the rotary shaft and does synchronous rotational motion along with the rotary shaft. The stator and the rotor are all arranged in the assembly chamber and collaboratively drive the rotor to do circumferential rotational motion. Thefront end face of the machine case extends backwards to be provided with an annular cooling groove. The cooling plates are fixed to the interior of the annular cooling groove. Thus, on the one hand,the heat dissipation area of the machine case can be effectively increased, the cooling capability of the machine case can be effectively improved, and accordingly, heat of the chamber of the machinecase can be dissipated to the outside in time; and on the other hand, there is no need to increase the volume and weight of the elevator traction machine, and it is ensured that the elevator tractionmachine has the low manufacturing cost.

    本发明涉及一种电梯曳引机,包括机壳、转轴、曳引轮、转子、定子、后端盖、前置轴承、后置轴承以及散热板。后端盖和机壳相互扣合,以共同形成一装配腔。前置轴承、后置轴承分别安装于机壳、后端盖上。转轴依序穿过前置轴承、装配腔、后置轴承。曳引轮套设于转轴上,且跟随转轴进行同步旋转运动。定子和转子均内置于装配腔内,且协同驱动转子进行周向旋转运动。由机壳的前端面向后延伸出有环形散热槽。散热板即内置、固定于环形散热槽内。这样一来,一方面,可有效地增加机壳的散热面积及其散热能力,从而有利于机壳腔体热量向外界的及时散发;另一方面,无须增加电梯曳引机自身体积以及重量,从而确保电梯曳引机具有较低的制造成本。
