Embodiment Construction

[0039] The present invention is described in detail below in conjunction with accompanying drawing:

[0040] The object of the present invention is to provide a train gearbox no-load running-in test bench with self-centering positioning and clamping device, which is used to detect the running-in condition of the gearbox under no-load state, so that the gearbox can meet the requirements of existing high-speed trains. its technical requirements. A certain 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 under no-load conditions. A torque speed sensor is installed between the driving motor and the gearbox, which can adjust different speeds and torques to apply power to the gearbox; the positioning and clamping device at one end of the wheel shaft is fixed, and is clamped with elastic clamp type double bearings The main shaft is positioned and clamped and transmits the power torque, and the other end is mobi...

Abstract

The invention relates to a gearbox no-load running-in test bed with a self-centering positioning and clamping device. The gearbox no-load running-in test bed is mainly composed of a driving device, a fixed end elastic clamping spindle positioning and clamping device, a movable end self-centering positioning and clamping device, a gearbox input end compression upright post device, a noise testing device and a test bed base, wherein the driving device is connected and mounted to the left end of the test bed base (1) via bolts, the fixed end elastic clamping spindle positioning and clamping device (4) is mounted on the left side of the test bed base (1), the movable end self-centering positioning and clamping device (9) is mounted at the right end of the test bed base (1), and the gearbox input end compression upright post device (8) is mounted on the test bed base (1) via a T-shaped bolt. The gearbox no-load running-in test bed solves a series of technical problems that the existing gearbox no-load running-in test bed is complex in dismantling and mounting, damages axle spindles and cannot meet high revolution speed and the like.

Description

technical field [0001] The invention relates to a rail vehicle gearbox test platform, more precisely, the invention relates to a rail vehicle gearbox no-load running-in test platform with a self-centering positioning and clamping device. Background technique [0002] At present, due to my country's implementation of the policy of greatly increasing the speed of railways, the running 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 maximum speed of the newly developed high-speed train set is close to 600km / h. However, the increase of train speed and the increase of vehicle axle load make the vibration between the vehicle and the track intensified, and the safety and stability of vehicle operation are prominent. As one of the important parts of the bogie of high-speed rail vehicles, the traction transmis...
