The invention discloses an elevator traction sheave rope groove design structure which comprises a rope groove body contour, and the rope groove body contour comprises a rope groove wall, a transition section, a lower notch groove, a tangent circle, an initial lower notch angle and a final lower notch angle; the transition section is connected with the rope groove wall and the lower notch groove; the tangent circle is tangent to the rope groove wall; the position of the final lower notch angle is determined through the rope groove angle gamma; when gamma is equal to 0 degree, the intersection point of the sunken tangent circle and the final lower notch angle is the width of the lower notch groove; the initial lower notch angle is larger than the final lower notch angle; the contour of the rope groove wall is a linear section or a combination of a straight line and an arc; the transition section is a linear section or a curve section, the starting point of the linear section or the curve section is the intersection point of the rope groove wall and the initial lower notch angle, and the terminal point of the linear section or the curve section is the upper starting point of the lower notch groove; and damage of a rope groove to a steel wire rope is reduced, the initial traction force is improved, the traction condition is improved, the elevator traction balance weight is reduced, unnecessary cost is reduced, and resources are saved.

    本发明公开了一种电梯曳引轮绳槽设计结构,包括绳槽主体轮廓,绳槽主体轮廓包括绳槽壁、过渡段、下部切口槽、相切圆、初始下部切口角和最终下部切口角;过渡段连接绳槽壁与下部切口槽;相切圆与绳槽壁相切;最终下部切口角的位置通过绳槽角γ确定;γ=0°时,相切圆下沉与最终下部切口角的交点为下部切口槽的宽度;初始下部切口角大于最终下部切口角;绳槽壁轮廓为直线段或直线与圆弧的组合;过渡段为直线段或曲线段,直线段或曲线段起点是绳槽壁与初始下部切口角的交点,直线段或曲线段终点是下部切口槽的上部起点;本发明减少了绳槽对钢丝绳的损伤,提高了初始曳引力,改善了曳引条件,减少了电梯曳引配重,降低不必要的成本,节约了资源。
