Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the drawings:

[0044] The object of the present invention is to provide a high-speed train gearbox no-load running-in test bench, which is used to detect the working condition of the gearbox running-in under no-load state, so that the gearbox can meet the technical requirements of existing high-speed trains. A certain amount of power is applied to the input end of the gearbox, and no load is applied to the end of the axle, so that the gearbox runs in under no-load conditions. A torque speed sensor is installed between the drive motor and the gearbox, which can adjust different speeds and torques to apply power to the gearbox; both ends of the wheel shaft are supported, positioned and transmitted power torque through the elastic clamp type double-bearing main shaft and the bearing seat ; Support the input end of the gearbox by pressing the column device and limit the rotation of the gearbox at the ...

Abstract

The invention relates to a high-speed train gearbox no-load running-in test bench, which is composed of a driving device, axle end transition bearing positioning clamping devices, a large-span mobile wheel set axle positioning supporting device, a gearbox input end pressing vertical column device and a noise testing device, wherein the driving device is arranged at the left end of a test bench base (1); a fixing-end and a mobile-end transition bearing positioning clamping devices are arranged at the left side and the right side of the test bench base (1) respectively; the large-span mobile wheel set axle positioning supporting device is composed of two sets of large-span mobile wheel set axle positioning supporting devices with the same structure; the gearbox input end pressing vertical column device is arranged on the test bench base (1); and the noise testing device comprises noise testing sound level meters and supporting tube assemblies arranged at the input end and the output end of the gearbox respectively. A series of technical problems that the existing gearbox no-load running-in test bench is complicated to assemble and disassemble, an axle journal is damaged, a high rotation speed can not be met and the like can be solved.

Description

Technical field [0001] The invention relates to a high-speed train gearbox running-in test platform, more specifically, the present invention relates to a high-speed train gearbox no-load running-in test platform. Background technique [0002] At present, due to the implementation of the policy of large-scale railway speed increase in my country, the operating speed of rail vehicles in my country has been greatly improved, which has also led to the rapid development of high-speed train technology. The maximum speed of high-speed trains already in operation has reached 350km / h, the highest speed of the newly developed high-speed train group is close to 600km / h. However, the increase in train speed and the increase in vehicle axle load have increased the vibration between the vehicle and the track, and the safety and stability of the vehicle operation have become prominent. As one of the important components of the high-speed rail vehicle bogie, the traction transmission gearbox is...
