The traction machine comprises a machine frame, a motor, a brake assembly and a manual brake releasing mechanism, the machine frame is an n-shaped machine frame, the motor is arranged on the left side of the left side wall of the machine frame, a main shaft of the motor rotationally penetrates through the right side of the machine frame from the left side of the machine frame, and a first traction wheel is arranged on the right side of the left side wall of the machine frame; a second traction wheel is arranged on the left side of the right side wall of the rack, and the first traction wheel and the second traction wheel are arranged on the main shaft. The brake assembly and the manual brake releasing mechanism are arranged on the right side of the rack and correspondingly penetrate through the tail end of the main shaft on the right side of the rack. The two traction wheels are arranged on the main shaft at a certain interval, when the traction wheels are subjected to radial load of the lift car, the bearings on the two sides jointly provide radial support, the main shaft has good rigidity and does not generate deflection deformation, meanwhile, the two traction wheels are designed in a separated and spaced mode, stress points between the traction wheels and the lift car are better balanced and evenly distributed, and the lift car is more stable. And vibration of the elevator car to the traction sheave in the elevator running process is eliminated.

    本发明提供了一种双曳引轮的别墅用曳引机,包括机架、电机、制动器组件和手动松闸机构,机架为“几”字型机架,电机设置在机架左侧壁的左侧,电机的主轴由机架左侧旋转穿设至机架右侧,机架左侧壁的右侧设置有第一曳引轮,机架右侧壁的左侧设置有第二曳引轮,第一曳引轮和第二曳引轮分别设置在主轴上;制动器组件和手动松闸机构设置在机架右侧并对应穿设出机架右侧的主轴末端设置。该发明通过在主轴上间隔一定距离设置两个曳引轮,曳引轮受到轿厢的径向载重时,两侧的轴承共同提供径向支撑,主轴拥有良好的刚性不会发生扰度变形,同时两个曳引轮分开间隔设计,使曳引轮与轿厢之间的受力点更好的平衡均布,消除电梯运行过程中轿厢对曳引轮的振动。
