The invention provides an overspeed governor wheel, an overspeed governor and a method for verifying the movement speed of the overspeed governor. The overspeed governor wheel is used for the overspeed governor of an elevator and comprises a plurality of annular rope grooves with unequal pitch diameters, the annular rope grooves are used for winding an overspeed governor steel wire rope (S) and thus transmitting movement of the elevator to the overspeed governor wheel, the different annular rope grooves can transmit the operation speed of the elevator to the overspeed governor wheel in different multiple relationships, and thus the overspeed governor wheel rotates at different speeds so as to verify the movement speed of the overspeed governor without removing the overspeed governor steelwire rope (S). The overspeed governor wheel and the overspeed governor are simple in structure, and the movement speed of the overspeed governor can be verified without removing the overspeed governorsteel wire rope and adopting overspeed governor movement speed verifying equipment. The method for verifying the movement speed of the overspeed governor is easy to operate and low in operating cost.
本发明提供一种限速器轮、限速器和限速器动作速度的校验方法。限速器轮用于电梯的限速器,其包括多个节圆直径不相等的环形绳槽,所述环形绳槽用于缠绕限速器钢丝绳(S)从而将电梯的运动传递给所述限速器轮,不同的环形绳槽能将电梯的运行速度以不同的倍数关系传递给所述限速器轮,使所述限速器轮以不同的速度旋转,以实现在不移除所述限速器钢丝绳(S)的情况下对所述限速器的动作速度进行校验。根据本发明的限速器轮和限速器的结构简单,可以在不移除限速器钢丝绳、不采用限速器动作速度校验设备的情况下对限速器的动作速度进行校验。根据本发明的限速器的动作速度校验方法操作简单,运行成本低。
