TESTER OF ROLLING BEARING OF CARRIAGE WHEEL

The utility model relates to a tester for rolling bearings of a carriage wheel, which is a device of a fault diagnosis system of undecomposed wheel bearings. According to the operating requirement, the tester for rolling bearings of a carriage wheel provides support, drive and load to the wheel bearing to cause the wheel bearing to run correctly so as to accurately and reliably collect fault signals. The tester for rolling bearings of a carriage wheel comprises a supporting assembly, a driving assembly, a loading assembly, a wheel track assembly for a body section and a lifting device which is arranged on the wheel track assembly for the body section or the supporting assembly. The wheel track assembly for the body section can make the heavy wheels accomplish filling the machine by the optimum displacement mode. The specimen machine of the tester for rolling bearings of a carriage wheel is applied to the fault diagnosis system of the undecomposed wheel bearings and is matched with other techniques of the fault diagnosis system, and the tester for rolling bearings of a carriage wheel obtain the good effects that the accurate diagnosis rate is more than 95%, and the missed diagnosis rate is almost zero.
