The purpose of the work is to study the dynamics and strength of the components of the elastic motor-axial drive of wheels on rolling bearings. Research methods - mathematical modeling of the dynamics of the elastic motor-axial drive of wheels on rolling bearings when moving vehicles on the track and analysis of the results.The original design of the elastic motor-axial drive of wheels on rolling bearings is developed, in which the torque and force of weight from the traction motor are transmitted to the wheel pair through elastic rubber (or polymer) silent blocks. They filter high-frequency destructive shocks coming from the track when moving and reliably protect the traction motor and motor-axial rolling bearings. Static deflection of elastic silent blocks from the force of gravity of the traction motor with the drive is not less than 0.003 m, which provides a natural vertical oscillation frequency of the traction motor of about 9.1 Hz, ie almost 5 times less than the natural vertical oscillation frequency of the rigid wheel motor unit. elastic track. This contributes to a significant reduction in the dynamic forces acting from the track on the traction motor and wheel drive, which increases their reliability in operation. The drive has the same control panel and gear ratio of the traction gearbox as the serial one, so the traction force of the locomotive does not decrease. Studies have shown that the selected parameters of the silent blocks, hollow shaft and other heavy-duty components of the drive provide the recommended reserves of their strength on the railway. It is recommended to use the developed elastic motor-axial drive of wheels on rolling bearings for modernization of 2TE116 locomotives Product Description popup.authors Yeritsyan Bagish H Liubarskyi Borys B Masliev Vjacheslav H Overianova Liliia V Riabov Ievgen S Iakunin Dmytro I popup.nrat_date 2022-03-09 Close
