This testing machine is used for performance testing, thermal testing, high and low temperature environment simulation testing and durability testing of traction motor bearings for high-speed railways and subway rail transit locomotives with an inner diameter range of 50-160mm.
Traction motor bearing testing machine is mainly used to test and evaluate the traction motor bearings of HXD1, HXD2, HXD3, HXN3, HXN5 electric locomotives and CRH type EMUs. The testing machine can more realistically simulate the use status of locomotive traction motor bearings, subjecting the bearings to corresponding loads, speeds, temperatures, vibrations and ambient temperatures for testing and evaluation. This testing machine is used for performance testing, thermal testing, high and low temperature environment simulation testing and durability testing of traction motor bearings for high-speed railways and subway rail transit locomotives with an inner diameter range of 50-160mm.
