ZWZ bearing railway wheel by Shijiazhuang Railway University acceptance

Recently, independent design, by the national large-scale bearing ZWZ engineering technology research center of railway bearing wheel experimental platform ZWZ equipment company is adopted in the production field of bearing replacement and dynamic test operation, leading in the experimental data and dynamic response speed, smoothly through the user acceptance of Shijiazhuang Railway University, has been sent to the user is installed debugging.

Shijiazhuang Railway College is the Hebei Provincial People's government, the National Railway Bureau, approved by the Ministry of education and universities, Hebei province is the key universities, which is distinctive in the direction of traffic emergency defense engineering, structural health monitoring, traffic environment and safety engineering etc.. ZWZ for the development of Railway Wheelset bearing experimental platform, mainly used in heavy haul railway, high-speed rail and urban rail bearing test. The experiment platform of rail transportation in the bearing load of work under the provisions of state, bearing wear fatigue life experiment, provide the basis for bearing failure analysis and life calculation; can test for fault bearing, such as bearing inner raceway, outer ring raceway, cage and roller crack, peeling, pitting the surface damage, by applying radial and axial dynamic and static load, the real operating environment to simulate the bearing, measurement of internal and external fault signal; can simulate the actual working state of locomotive vehicle bearing, automatic application of line load spectrum, velocity spectrum and wind speed spectrum of locomotive vehicle bearing dynamic simulation experiment. The maximum outer diameter of the experimental bearing is 350mm, the maximum speed of the test bench can reach 3400r/min, the maximum static radial load is 150KN, and the maximum static axial load is 100KN.

In recent years, ZWZ bearing large national engineering research center of test equipment to meet the company needs at the same time, and actively expand the external market, special equipment R & D truck wheel hub test machine leading, to meet the needs of users, to achieve the ZWZ industrial chain from manufacturing extended to two, by providing products to provide the overall solution the direction of development.
