The invention relates to the technical field of elevators, and discloses a traction machine unbalance loading measuring method and system.The traction machine unbalance loading measuring method comprises the steps that when a traction machine is in a non-working state, a first gap between a first electromagnet and a first weighing inductive switch is made to be equal to a second gap between a second electromagnet and a second weighing inductive switch; measuring a first compression value of the shock pad; enabling the traction machine to be in a working state, and measuring a first induction voltage of the first weighing induction switch and a second induction voltage of the second weighing induction switch; measuring a second compression value of the shock pad; according to the first compression value and the second compression value of the shock pad and the difference value between the first induction voltage and the second induction voltage, the unbalance loading condition of the traction machine is obtained. The device has the advantages that the unbalance loading condition of the traction machine is indirectly obtained through the difference value of induced voltages on the first weighing inductive switch and the second weighing inductive switch and the compression amount of the shock pad, the precision is high, the cost is low, measurement is convenient, and noise is low.

    本发明涉及电梯技术领域,公开一种曳引机偏载测量方法及系统,该曳引机偏载测量方法包括:在曳引机处于未工作状态时,使第一电磁铁与第一称重感应开关之间的第一间隙,等于第二电磁铁与第二称重感应开关之间的第二间隙;且测量减震垫的第一压缩值;使曳引机处于工作状态,测量第一称重感应开关的第一感应电压,及第二称重感应开关的第二感应电压;并测量减震垫的第二压缩值;根据减震垫的第一压缩值和第二压缩值,及第一感应电压和第二感应电压间的差值,得出曳引机的偏载情况。本发明的优点在于,通过第一称重感应开关和第二称重感应开关上感应电压的差值,及减震垫的压缩量间接得出曳引机的偏载情况,精度高、成本低、测量方便,且噪声小。
