铁路轴承内外圈

Railway bearing inner and outer rings

该设备是根据对机车轴承环磁粉探伤要求而设计，是固定式、半自动化设备。采用连续法复合磁化，用可编程控制器控制节拍，检测客车轴承内外环、货车轴承外环表面及近表面因锻压、淬火研磨、疲劳引起的裂纹、夹渣等缺陷。设备采用穿棒法与U型磁轭法对工件进行复合磁化。工件进行磁化时不接触工件，属于无接触式。设备一次上料即可完成穿棒、喷洒、充磁、转动观察、退磁等工序，根据工作需要可手动或自动操作，使用方便。具有操作简单，探伤效率高，安全、可靠、工人劳动强度低等特点。

This equipment is designed according to the requirements for magnetic particle inspection of locomotive bearing rings. It is a fixed and semi-automatic equipment. The continuous composite magnetization method is adopted, and the beat is controlled by a programmable controller to detect defects such as cracks and slag inclusion caused by forging, quenching and grinding, fatigue and the like on the inner and outer rings of the bus bearing, the outer ring surface of the truck bearing and the near surface. The equipment adopts the rod penetrating method and the U-shaped yoke method to carry out omnidirectional composite magnetization on the workpiece. When the workpiece is magnetized, it does not contact with the workpiece, which belongs to non-contact type. The equipment can complete the processes of rod threading, spraying, magnetizing, rotating observation, demagnetization and the like by once feeding, and can be operated manually or automatically according to work requirements, thus being convenient to use. It has the characteristics of simple operation, high flaw detection efficiency, safety, reliability, low labor intensity of workers, etc.
