Abstract

The invention relates to a single-bearing motor test tool. The locking device of the tool is disposed on a side of the longitudinal direction of a supporting device, and operatively fixes the casing of the motor. The middle portion of the vertical plate of the supporting device is provided with a mounting hole, and a connecting flange is installed in the mounting hole. A bearing is installed in the middle of the connecting flange. A rotating shaft is rotatably mounted in the bearing. A blocking device is disposed on the other side of the longitudinal direction of the supporting device. The diaphragm coupling of the blocking device is fixedly mounted on the rotating shaft, and is provided with four blocking holes. Two supporting columns are oppositely arranged on the bottom plate on the tworadial sides of the diaphragm coupling. Through holes pass through the supporting columns. The head of a blocking rod passes through the through holes on the supporting columns and can be inserted into the blocking holes on the diaphragm coupling. The single-bearing motor test tool can perform performance test on a powered-on motor to meet the use requirements.

Description

technical field [0001] The invention belongs to the technical field of test tooling, in particular to a single-bearing motor test tooling. Background technique [0002] At present, the locomotive traction drive system is called "the heart of the train" in the industry, and the performance of its core component, the motor, is the key to determining the performance of the whole vehicle. [0003] In the process of realizing the present invention, the filing date found that there are at least the following deficiencies in the prior art: [0004] Single-bearing motors are tested during the production process and after maintenance. Since there is only one bearing support point, electrical characteristics such as speed and torque cannot be tested, which cannot meet actual needs. Contents of the invention [0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a single-bearing motor test tool, so that the performance test of the ...
