摘要（英）：

The invention provides a locomotive motor gear hot-charging limiting tool and an installation method. The locomotive motor gear hot-charging limiting tool comprises a sleeve, a locating rod and a locating nut, a screw mechanism is arranged on the first end portion of the locating rod, the inner and outer walls of the first end portion of the sleeve are separately provided with thread mechanisms, and the screw mechanism and the locating nut are connected to the first end portion of the sleeve in a threaded mode. The second end portion of the locating rod passes through the sleeve and extends out of the sleeve, the locating nut is provided with a first locating plate, and a second locating plate which is arranged opposite to the first locating plate is arranged on the second end portion of the sleeve. The gear can be installed on a motor shaft in a hot-charging mode through the locomotive motor gear hot-charging limiting tool to improve the efficiency and precision of gear installation.
