An elevator with a stable operation function comprises a traction wheel and a steel wire rope wounded on the traction wheel. The traction wheel comprises a first traction area, a second traction areaand a third traction area which are sequentially arranged in the axial direction and are all provided with rope grooves. The steel wire rope passes through the rope groove of the first traction area and is guided by a guiding mechanism so as to sequentially pass through and be wounded in the rope grooves of the third traction area and the second traction area. A downward wrap angle 1 is formed bythe steel wire rope and the first traction area. An upward wrap angle 2 is formed between the steel wire rope and the third traction area. A downward wrap angle 3 is formed between the steel wire ropeand the second traction area. The steel wire rope is wounded out of the rope grooves in the tangential direction of exit points where the steel wire rope is in contact with the rope grooves, and thenis wounded in the rope grooves in the tangential direction of enter points where the steel wire rope is in contact with the rope grooves. According to the elevator, the friction area between the steel wire rope and the traction wheel is large, slipping or detaching is not prone to happening, operation of the elevator is stable, damage to a spindle of a traction machine is small, and operation ofthe traction machine can be guaranteed for a long time.
一种平稳运行的电梯,包括曳引轮以及绕在所述曳引轮上的钢丝绳,所述曳引轮包括轴向依次设置的均具有绳槽的第一曳引区、第二曳引区以及第三曳引区,所述钢丝绳经第一曳引区的绳槽后由导向机构引导实现依次经过并绕在第三曳引区、第二曳引区的绳槽上,且钢丝绳与第一曳引区形成向下的包角1,钢丝绳与第三曳引区形成向上的包角2,钢丝绳与第二曳引区形成向下的包角3;所述钢丝绳,其沿着钢丝绳与各所述绳槽相接触的引出点的切线方向绕出绳槽,沿着钢丝绳与各所述绳槽相接触的引入点的切线方向绕在绳槽上。本发明,钢丝绳与曳引轮的摩擦面积大,不易打滑,且不易滑脱,电梯运行平稳,对曳引机主轴的损伤较小,能够长期保证曳引机的工作。
