The invention belongs to a technology for detecting wheel set bearings of running positions of a railway carriage and a lorry, providing an intelligent online detecting method for a railway bearing and a device using the same. The device mainly comprises a lathe bed (1), a vibration detecting mechanism, a torque detecting mechanism, a correcting mechanism and a computer (38). The method and the device have the advantages that: the intelligent online detecting method for the railway bearing and the device using the same can be used for detecting abnormal information, structural health and failure diagnosis of wheel set bearings for internal railway lorries in utilization states. The method can replace the prior detecting method which completely adopts manual detection to detect the condition of the wheel set bearing in non-disassembly condition by the manual operation of a worker according to feeling in the rolling stock depot. Compared with over 600,000 railway carriages and lorries in the country, the method and the device not only reduce labor intensity for workers, but also have a positive promoting effect for preventing accidents, so that bearing online detection and analysis for railway in the country can be quickly and healthily developed.
