Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, and particularly relates to a measuring tooling for the coupling of a subway vehicle bogie. Background Art
[0002] In subway vehicles, the height difference of the coupling of the bogie is a very important system. If the coupling error is too large, during the operation of the vehicle, it may cause the couplings to collide and rub against each other during operation, generating abnormal noises, and in severe cases, it will affect the normal operation of the vehicle. At present, according to the requirements, the height difference of the coupling is measured, and the conventional test methods are as follows:
[0003] ① Horizontally place the height calibration tool on the rail surface, vertically under the coupling, and fix it.
[0004] ② Select measurement points on the inner gear sleeve surfaces of the two half-couplings respectively, and the distances between the two measurement points (the distances from the tooth meshing center line) are equal to the middle position of the coupling.
[0005] ③ Align the height scale of the height calibration tool with the measurement point of the motor-side half-coupling, and read the reading H1 of the height scale.
[0006] ④ Move the height scale rod to the measurement point of the gearbox-side half-coupling, and read the reading H2 of the height scale.
[0007] ⑤ The difference H between the two readings, H = H1 - H2, is the height difference between the motor shaft and the driving gear shaft.
[0008] This measurement method not only takes more personnel and time, but also has low accuracy and is prone to errors. At the same time, by consulting and analyzing relevant documents, an inclinometer can be used to measure the angle difference of the coupling. However, due to the special structure of the bogie, the inclinometer cannot measure normally. In summary, using the conventional height difference method for measurement cannot meet the measurement requirements, and it is particularly necessary to design a special tooling for measuring the angle difference of the coupling. Content of the Utility Model

[0010] To achieve the above object, the utility model is realized by the following technical solutions: A measuring tool for the coupling of a subway vehicle bogie, including a tool body, which is composed of a left support part, a right support part, and a connecting part.

The front end of the left support part is a left arc measuring part that matches the outer periphery of the inner tooth sleeve surface of the coupling, and the front end of the right support part is a right arc measuring part that matches the outer periphery of the inner tooth sleeve surface of the coupling.

[0027] It should be noted that both the left arc measuring part 1-4 and the right arc measuring part 1-5 are inner arc chamfers.

During measurement, the left arc measuring part 1-4 and the right arc measuring part 1-5 corresponding to each support part are attached to the outer wall of the measuring point, and then the inclinometer 2 is placed on the connecting part 1-3 to complete the measurement.
