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...
