Problems solved by technology

If the driving gear of the train is loose or cracked during operation, especially when the locomotive is under low-speed and heavy-load traction conditions, it will cause the motor winding to burn out and seriously affect the driving safety of the locomotive.
The loading amount of the gear on the motor shaft is 1.7-1.9mm, the installation accuracy is high, and it is difficult to ensure the installation accuracy by the cold pressing process

Abstract

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.

Description

technical field [0001] The invention relates to mechanical tooling, in particular to a heat-fitting limit tooling for a railway locomotive motor gear and an installation method. Background technique [0002] At present, the driving gear of the traction motor is one of the key parts for power transmission of the locomotive profile. It is assembled with the motor shaft in the form of a conical shaft interference fit. When the locomotive is running at full load, it transmits the strong traction of the train. If the driving gear of the train gets loose or cracks during operation, especially when the locomotive is under low-speed and heavy-load traction conditions, it will cause the motor windings to burn out, seriously affecting the driving safety of the locomotive. The loading amount of the gear on the motor shaft is 1.7-1.9 mm, and the installation accuracy is relatively high. It is difficult to ensure the installation accuracy by the cold pressing process. How to design a te...
