The invention relates to the technical field of elevators, in particular to a device and a method for measuring the running precision of a guide wheel or a diversion sheave of an elevator. The measuring method comprises the following steps: measuring the actual inclination amount of the end face of the outer ring of a bearing for bearing the guide wheel or the diversion sheave by using a pressure sensor and a spring; obtaining the maximum radial clearance value of the bearing; obtaining a maximum inclination amount based on the maximum radial clearance value; determining a rotation precision judgment value based on the planeness of the outer ring of the bearing, the allowable axial circle run-out of the end face of the outer ring of the bearing to the reference and the maximum inclination amount; and obtaining an actual rotation precision value based on the actual inclination amount, and comparing the actual rotation precision value with the rotation precision judgment value to confirm whether the rotation precision of the bearing is qualified or not. The measurement method and the measurement device provided by the invention can realize numeralization of rotation precision and effectively improve detection precision.

    本发明涉及电梯技术领域,特别涉及一种电梯导向轮或反绳轮的运行精度的测量装置及测量方法。其中,所述测量方法包括:使用压力传感器和弹簧测量承接所述导向轮或反绳轮的轴承外圈端面的实际倾斜量;获得所述轴承的最大径向游隙值;基于所述最大径向游隙值获得最大倾斜量;基于所述轴承外圈平面度、所述轴承可允许的外圈端面对基准的轴向圆跳动和所述最大倾斜量确定回转精度判定值;基于所述实际倾斜量获得实际回转精度值,将所述实际回转精度值与所述回转精度判定值对比,确认所述轴承的回转精度是否合格。本发明所提供的测量方法和测量装置可实现回转精度的数值化,有效提高检测精度。
